This study measured the real-world energy use of lifts/elevators in office buildings and found it was 16-36% higher than predicted by industry standards. It also found that promoting stair use through signs and challenges could significantly reduce lift/elevator energy use and save an average of 94 kWh per year for every 10 additional people switching from lifts to stairs. While useful for comparisons, conventional measures of lift/elevator energy use are likely to underestimate actual energy consumption. Stair promotion programs should be considered to lower energy costs and waiting times as well as promote health, as recommended.

News release - European industry can save 5 billion tons of CO2 by 2050Leonardo ENERGY
According to a study conducted by the Leibniz University-Hannover and the Copper Alliance, the five biggest energy-intensive industrial branches in Europe have the potential to save more than 5 billion tons of CO2. They can do this by switching from fossil energy to 100% electricity for heat production. The technology needed for this switch is available through electromagnetic processing of materials (EPM). The significant CO2 savings can be achieved thanks to the ever-increasing contribution of renewable sources to electricity generation in Europe, in combination with the inherent efficiency of EPM technologies.

[Oil & Gas White Paper] Gas Measurement and Analysis to Support FinancialsSchneider Electric
An advanced gas measurement and analysis system provides several benefits to natural gas companies: it continuously monitors pipeline measurements and validates the data in real-time to ensure accuracy for financial reporting; it determines gas composition which is needed to calculate energy content and greenhouse gas emissions; and it detects equipment issues and supports efficient maintenance. This system enables best practices around transparency, estimation, balancing, and documentation of measurement data across the enterprise to improve operations, competitiveness, and environmental stewardship.
Energy-intensive industries – energy efficiency policies and evaluationsLeonardo ENERGY
The webinar will review results from academic evaluations of energy efficiency and climate mitigation policies that have targeted energy-intensive industry on EU and Member State level. The EU emissions trading system, by some portrayed as Europe´s flagship policy to tackle climate change, has had little effect in triggering innovative low-carbon solutions. Other policy approaches taken by Member States have centred on site-level energy management practices linked with national incentives and obligations that stimulates industrial energy efficiency as a strategy aiming at multiple objectives. Remarks are also made about policy design and the role of evaluation to foster policy improvements.

5th International Conference : Angela Druckmanicarb
This document discusses taking a whole systems approach to carbon accounting and avoiding unintended consequences. It presents a typology of unintended consequences including:
1. Knowable and avoidable consequences like inefficient toilets using more water than necessary.
2. Hard to assess consequences like the increased emissions from indirect land use change due to biofuels leading to deforestation.
3. "Knowable" but unavoidable consequences like rebound effects where improvements in energy efficiency lead to increased rather than decreased energy use through things like driving more or heating larger homes.
The document discusses strategies for greening supply chains through industrial energy efficiency retrofits. It found that 30-50% reductions in energy intensity are possible in many factory processes. There are generally four types of energy efficiency projects that can be implemented: 1) simple and low-cost projects with quick paybacks, 2) a series of low-cost projects implemented together, 3) larger and more complex projects affecting overall energy usage, and 4) a portfolio of moderate projects completed sequentially. Engaging factories and providing support through audits, financing, expertise and ensuring data monitoring are keys to successful implementation.
DSM (Demand Side Managament) has changed since it was first introduced in the 1980s as an active policy instrument to make energy systems perform better and more economically. In the years since and primarily in the early years of the new millennium technology has provided new opportunities with smarter applications, decentralised power making use of local renewable sources and with a booming IT for management. We rather talk about Integrated DSM (IDSM).
Policy challenges to make energy systems sustainable and reduce (prevent) climate change has been more pronounced with the Paris accord as the ultimate example. Still market uptake is slow and well beyond expectations (and needs).
It is time for DSM to shape up and deliver!

ENERGY IN BUILDINGs 50 BEST PRACTICE INITIATIVESJosh Develop
Technology, economics and policy are rapidly transforming energy markets
and the broader economy. Global efforts to reduce emissions of greenhouse
gases are leading to increased focus on policies that can reduce energy use
or promote low emissions generation.
Australia’s economy-wide target under the United Nations Framework
Convention on Climate Change is to reduce emissions by 26-28 per cent
on 2005 levels by 2030. By the second half of the century, achieving net zero
emissions is likely to be necessary to meet international climate commitments.
The cost of producing electricity from renewable resources has declined
significantly over recent years and remains on a rapid downward trajectory.
This document summarizes the findings of a feasibility study into designing and delivering new net zero carbon buildings. The study analyzed two real-world development projects - an office tower and residential block - and compared their original designs to revised net zero designs.
The key findings were that achieving intermediate 2025 net zero targets would result in modest cost increases of 6.2% for the office and 3.5% for the residential building. However, more ambitious 2030 stretch targets led to higher cost increases of 8-17% for the office and 5.3% for the residential building. Overall, the report provides evidence that new buildings can be designed to achieve net zero carbon operations but that support and long-term policy are needed to
This document summarizes the key parameters for upgrading existing buildings to become green buildings. It discusses the markets and benefits for greening existing office, retail, and other commercial buildings. It also examines the costs of upgrading buildings, including cost drivers and return on investment. Some of the main challenges of greening existing buildings are barriers like higher perceived costs, unproven benefits, and lack of appropriate financing. Overall green buildings can provide economic benefits through reduced operating costs, higher rents and occupancies, and marketing advantages.
This report examines options for a green, low carbon community in and around Linlithgow Cross in Scotland. It conducts a baseline survey of energy use in the area and considers seven technologies for reducing carbon emissions, including biomass boilers, CHP systems, heat pumps, and superinsulation. Capital costs for the options range from £1.68 to 5.89 million, with payback periods from subsidies of 5.5 to 196.5 years. The report recommends pilot projects using ground source heat pumps, micro-CHP, and superinsulation at specific buildings identified as energy "hotspots". It emphasizes the need for immediate action to secure funding and leverage available government subsidies to facilitate the transition to low carbon
The document discusses standards being developed for carbon accounting in buildings and construction. It notes that BSI, CEN, ISO, and other standards bodies are working on frameworks to measure embodied carbon in products and services as well as carbon emissions from buildings, materials, and systems throughout their lifecycle from production to use to disposal. The document raises questions about what exactly is being standardized, such as whether it is focusing only on carbon or broader environmental impacts, and whether the standards are for products, systems, or whole buildings.
Towards a Standard for Carbon Accounting | Hywell Daviesicarb
The document discusses carbon accounting standards and metrics for buildings. It notes several ongoing standardization efforts and makes recommendations for carbon accounting, including:
- Defining clear system boundaries and accounting for all scope 1, 2, and 3 emissions
- Developing consistent metrics that allow for comparisons across sectors and activities
- Collecting better quality performance data to improve benchmarking
- Reporting on normalization factors to provide full context for emission reductions
A high performance green building is designed for economic and environmental performance over its entire life cycle, considering unique local climate and cultural needs and providing for the health, safety and productivity of its occupants. With continuous care over its life cycle, it minimises energy use, CO2 emissions, and total environmental impacts, and provides ongoing measurable value to building owners, occupants and society.
Business guide on carbon emission redution and sustainabilityBarney Loehnis
This document provides a 6-step guide for businesses to reduce emissions and addresses climate change. It discusses the risks of climate change and regulations, measuring emissions, setting reduction targets, implementing initiatives, offsetting remaining emissions, and tracking progress. Solutions discussed include energy efficiency in buildings, lighting, office equipment, and green procurement. The business case for action includes cost savings, competitive advantage, and responding to future regulations and consumer expectations.
This report analyzes energy efficiency improvements in shopping centers and their impact on operational costs and asset values. It finds that completely replacing old, energy intensive equipment with new, more efficient equipment produces reductions in energy and maintenance costs, resulting in upward shifts in shopping center values. For relatively modern centers, values increase over 1%, while for older centers values increase substantially over 5%. Failure to make these investments risks effective loss of value up to 5.5% for a £100 million center. The report develops a valuation model to assess impacts across various center types and scenarios. It recommends regular assessments of energy performance and incorporation of energy plans into strategic management to maximize values over the long term.

The Ska environmental rating tool for fit-outs has become widely adopted since its launch five years ago. It promotes sustainability in fit-out and refurbishment projects, which represent a significant portion of UK construction spending and carbon emissions. Ska assessments evaluate projects based on their implementation of simple, good practice measures rather than overall building performance calculations. This makes it suitable for fit-outs that only impact part of a building. While Ska use is growing, few building services engineers are yet trained as assessors, despite fit-outs requiring their input. RICS continues expanding Ska to more sectors like higher education.

This document is the final report of an Innovation and Growth Team examining how the UK construction industry can transition to a low carbon economy. It finds that the construction industry has an opportunity to lead this transition through low carbon product and service innovation. However, a "quantum change" is needed to meet UK climate targets. There are common barriers across sectors, including a lack of clarity on the transition path, a need for government-industry cooperation, and a lack of market incentives for low carbon construction. The report makes recommendations to address these barriers and enable the construction industry to fully realize its potential role in achieving the UK's carbon reduction goals.
Joining Forces - the case for collaborationAlex Lankester
This document discusses the benefits of collaboration between businesses in achieving sustainability goals. It argues that tackling sustainability challenges requires coordinated collective action across supply chains. Working collaboratively through fully-linked information sharing can help businesses save money by reducing impacts and risks, and innovating and growing. Examples show energy efficiency collaborations generating estimated savings of hundreds of millions of euros for food suppliers. Collaboration supports identifying and implementing initiatives like LED lighting and refrigeration upgrades. Case studies demonstrate individual companies achieving energy and cost savings by learning from others' experiences through collaborative platforms.
Out of Hours: The Easiest Way to Improve Building Energy EfficiencyGreensense
This document discusses how reducing energy use in buildings during the 72% of time they are typically unoccupied can be one of the easiest and most impactful ways to improve energy efficiency. It notes that on average, 55% of total electricity usage in commercial buildings occurs when they are empty. The document examines the costs of this wasted energy use and identifies common energy vampires like electronics and appliances that are left on. It provides recommendations for analyzing usage data, engaging occupants, and implementing simple solutions to curb out-of-hours consumption.
The UK has a productivity problem that could threaten economic growth. While GDP has recovered from the 2008 downturn, productivity has not kept pace and lags behind other G7 nations. Only 54% of employees feel their workplace enables productivity. However, research shows the workplace environment impacts performance. Intelligent buildings that use IoT sensors to monitor comfort factors like temperature, noise and lighting can provide data to optimize conditions and boost productivity. Adopting such technology could help solve the UK's productivity puzzle.

4. Smarter Buildings Study - 2016 | 4
Foreword
Commercial buildings account for over half of all electricity use in the UK and as much as 50% of
this is estimated to be wasted.
Rising energy costs, combined with ethical and regulatory pressures on companies to report annual
reductions in carbon output, are placing ever greater pressures on property businesses to improve
the environmental performance of their buildings. In parallel, tenants are demanding significant
improvements to the biological or ‘human’ sustainability of commercial buildings. In short, it is no
longer enough for modern office buildings to be ‘green’. They must also benefit the health and
productivity of those who work within them.
A major report published last year by the World Green Building Council, and sponsored by JLL,
Land Lease and Skanska, called for human health to be seen as an integral part of sustainability by
the property sector. New health related certification schemes, such as the Delos WELL Building
Standard and the UK’s Healthy Workplace Charter are now formally rating office buildings for health
- ratings that are now actively being sought by prospective tenants.
It is no surprise then that property businesses are devoting increasing priority and budget not just
to the fabric of their buildings but to the health of those within them. However, managing these
twin drivers of tenant demand is far from straightforward. While there is significant overlap between
environmental sustainability and human health, it is not always the case that improvements in one
area benefit the other.
This paper focuses on an area in which synchronicity between environmental and human health is
clearly evident; one in which outcomes on both sides of the equation are positive, cost effective and
significant.
In the wake of concerns over emissions reporting in the motor sector, it aims not only to provide new
real-world data against which to evaluate lift/elevator systems but to equip property professionals
with a simple mechanism through which to demonstrate to tenants their health and environmental
credentials.
Our findings on the real-world energy consumption of lifts will no doubt trouble property managers
and perhaps even regulators. Certainly it should cause many to revisit the carbon and energy
consumption data for lifts/elevators in their buildings.
Yet there is something that can be done. Our data shows that incentivising stair use appears
to significantly reduce lift/elevator energy consumption. Stair promotion also ticks a box that
is prominent in all the new health certification standards and government workplace health
recommendations. For property owners and managers it therefore one of those rare things: a low-
cost and easy-to-implement solution that kills two birds with one stone.

Executive summary
This study aimed to directly measure lift/elevator energy consumption in typical multi-storey office
buildings and to compare these ‘real-world’ results with manufacturer’s estimates.
We then examined the impact of stair promotion programmes on lift/elevator journey patterns and
energy consumption. The financial savings businesses could make, as well as the quantity of carbon
emissions that could be saved by switching from lifts use to stair use, was then calculated.
Methods
Real-world lift energy consumption was measured across the three principal lift types (hydraulic,
geared and gearless traction) in three office building scenarios using a high-specification digital data-
logger. Real-world stair-use data was also collected.
All data were modelled using Elevate1
lift traffic analysis software. Results were compared with the
predictions for energy use given by VDI 47072
, the industry standard protocol for estimating lift/
elevator energy consumption.
A wide-ranging literature search was conducted to inform and augment the study’s wider discussion
and conclusions.
Results
• Lifts/elevators were found to burn 16% to 36% more energy in real-world use than the de facto
international standard (VDI 4707) predicts.
• The most commonly installed lift type – geared traction lifts – were the worst offenders. The gap
between predicted and measured energy consumption was 36%.
• Changing working patterns appear to have increased pressure on lift/elevator systems by
increasing inter-floor journeys. Standard predictive models of lift/elevator use appear to
underestimate this change, explaining much of the discrepancy between the predicted and
measured energy use.
• Stair use has a larger mitigating impact on lift use than the standard industry model suggests. For
every ten additional building occupants who switch from lift to stair use, the real world modelling
predicts an annual average energy saving of 94 kWh.

Conclusions
Conventional measures of lift/elevator energy use should be employed with caution. While useful for
comparing lift systems on paper, it is clear that they are likely to significantly underestimate real-
world energy use.
Stair promotion programmes should be considered to mitigate lift/elevator energy costs and waiting
times and - in line with official recommendations - to promote physical activity and productivity
among office workers.

Introduction
The ‘green building’ sector has flourished over the past 20 years and is now a trillion dollar indus-
try globally3
.
Certification schemes, such as LEED and BREEAM, have been widely adopted and enable the
environmental performance of a building’s life-cycle to be robustly assessed. The number of green
buildings in the UK risen from 1.5% in 2005 to 13.2% in 20134
. For larger UK office buildings, the
proportion with green certification now exceeds 40%.
Despite this progress, commercial and domestic properties accounted for 51% of electricity use in the
UK in 20145
and were responsible for 37% of total greenhouse gas emissions6
. It is this statistic more
than any other that explains the unrelenting regulatory and ethical pressure on the property sector to
further improve its performance. With it are coming a welter of new standards and targets, several of
which directly link environmental performance to taxes due.
Yet at the same time property businesses are faced with the reality that environmental improvements
are becoming smaller, harder to come by and more expensive to implement. This is because much of
the ‘low hanging fruit’ has long since been picked.
Currently lighting and lighting controls are the most highly commissioned energy efficiency
measures. Lift/elevator, heating, ventilation and air conditioning (HVAC) technologies have, to date,
received much less attention - largely due to their perceived cost.
Suspect data
Compounding this problem further is the erosion of the credibility of sustainability data. Just as the
motor industry has run into serious trouble over the recent emissions scandal, there is evidence the
same may be happening in property.
Recent research by the UK government agency, Innovate UK, highlights a significant gap between
the emissions predicted at a building’s design stage and its performance in reality7
. Of more than 100
commercial and domestic construction projects, it found that, on average, carbon emissions from
non-domestic buildings were nearly four times their design estimate. Shockingly, carbon emissions
matched the original design estimate in only one of the 49 commercial properties studied.
“Homes and offices are not performing as they should do. They are consuming up to 10 times the
energy they should”, said Simon Hart of Innovate UK at the launch of the report.

Healthy buildings
To further complicate matters, tenants are starting to add measures of ‘human sustainability’ to the
growing list of benefits they expect modern offices to deliver.
With ‘people costs’ representing by far the biggest slice of most businesses’ outgoings and mounting
evidence to show that staff health and productivity strongly correlate to the quality of the work
environment, it makes excellent economic sense for prospective tenants to prioritise offices that can
be objectively classed as ‘healthy’.
Facilities management businesses have been aware of this trend for some time but the response
of the majority to date has been largely marketing-led and limited to sloganeering on the lines of:
“We don’t just care for your building but your people too”. That, however, is now starting to change
quickly as more rigorous and objective health certifications for buildings are introduced.
The new Delos WELL Building Standard is the most developed of these to date and appears to be
gaining rapid traction in the US, Europe and Australia. The standard brings together best practices in
design and construction with scientific and medical research in human health.
Backed by the Mayo Clinic in the US, it sets out a long list of criteria that an office or building must
meet before being classed as WELL Certified. Everything from air quality to a building’s propensity
to promote incidental physical activity and fitness is covered. The certification process includes an
onsite audit and is awarded at one of three levels: Silver, Gold and Platinum.
Movement is key
Of all the aspects of an office building that impact on human health, it is its ability to drive regular
physical movement among tenants that (beyond basic health and safety) is the most important.
Sedentary behaviour (sitting) has been identified by the World Health Organization as one of the
single biggest drivers of global ill-health, responsible for as many deaths as smoking8
. According to
Public Health England, prolonged sitting is associated with a wide range of long-term conditions
including obesity, diabetes, heart disease and several cancers9
. It can also negatively impact office
workers’ mental health, productivity and overall sense of wellbeing.
Offices are one of the biggest - perhaps the biggest - offenders when it comes to sedentary
behaviour. British people are estimated to sit for an average of 8.9 hours a day, with 70% of this
sitting time being at work10
. Within the office, studies suggest that 76% of our time is spent sitting. Of
the time not spent sitting, only 4% is classed as moderate physical activity (ie. activity which raises
the heart rate).

10. Smarter Buildings Study - 2016 | 10
It’s important not to confuse sedentary behaviour (sitting) with a lack of exercise generally. The
scientific evidence base now suggests that sitting in and of itself is bad for human health and may
not be offset even by vigorous exercise outside work hours11
. It is this that explains the increasing
focus by health regulators around the world on the creation of ‘active workplaces’. Common solutions
include the promotion of:
• Stair use
• Breaks and breakout spaces
• Walking meetings
• Standing desks
“Simple behaviour changes to break up long periods of sitting can make a huge difference”, says Dr
Ann Hoskins, of Public Health England.
Lifts and stairs
This study focuses on the interaction between lifts/elevators and stairs because it represents a
simple and yet largely unexplored opportunity to produce significant health and environmental
improvements without the need for large scale investment or re-engineering.
Real-world data is also now, for the first time, available on lift/energy consumption and ‘stair factor’
(the impact stair use has on the frequency and pattern of lift/elevator journeys).
Lifts/elevators are significant consumers of electricity within commercial buildings. They account
for up to 3-8% of all energy used12
and there are estimated to be 8.5 million lifts/elevators operating
worldwide13
. Yet in virtually all buildings with lifts/elevators there will also be one or more fully
maintained staircases capable of serving an entire building’s population under fire regulations.
Lift/elevators are not just a drain on energy. They are eating up an increasing amount of tenant
time. Changing working practices (flexitime, hot-desking etc) have altered the pattern of lift use
significantly over the past 20 years14
. There are now many more inter-floor journeys which - despite
the advent of new ‘smart’ call systems - has led to a significant jump in lift/elevator waiting times.
Few facilities managers now escape daily complaints from tenants on this count. Underlining the
issue, the IBM Smarter Building survey 2010 found that US office workers collectively spent 33 years
in elevators in the previous 12 months. Even more time was spent waiting for them – 92 years in
total15
.
The cumulative productivity loss is enormous. Taking the stairs instead of a lift/elevator is - on
average - quicker for most journeys of up to seven floors. A high-quality study conducted in a
Canadian hospital found that staff who took the stairs rather than lift/elevators saved 15 minutes each

per day (or about seven working days per year)16
.
On the other side of the equation are the health benefits of stair use. Stairs have always been a
mainstay of ‘active design’ and are recommended by the WELL Building Standard and health
authorities the world over as a means of promoting movement and health in the urban environment.
It is not only a form of physical activity that is habit forming and accessible but one which has well-
documented health benefits. Findings from high-quality studies include:
• Climbing just eight flights of stairs a day lowers average early mortality risk by 33%17
.
• Seven minutes’ stair climbing a day can halve the risk of heart attack over 10 years18
.
• Just two minutes’ extra stair climbing a day is enough to stop average middle age weight
gain19
.
As an area for property businesses to pilot, the new intersection between environmental and human
sustainability, lifts/elevators and stairs appears ideal. Table 1 below summarises the principal benefits
that would be expected to flow from schemes that successfully altered the balance between stair and
lift/elevator use in modern multi-floor office buildings.

Study design
The study set out to answer two distinct questions: Does the predicted energy use of lifts/elevators
using industry standard protocols match the real-world energy use of lifts/elevators? And does
increasing stair use in a modern office building impact upon the energy use of lifts/elevators?
To answer these questions we:
1 Sourced real-world data on the in situ energy consumption of lift/elevators in a range of UK
office buildings.
2 Sourced real-world data on on the impact of stair promotion schemes by UK corporates (stair
prompts and gamification).
3 Compared real-world energy consumption data with that predicted by industry standard
models for different lift types.
4 Calculated the impact stair promotion schemes had on lift journey patterns and energy
consumption.
Baseline scenarios
Lifts/elevators are usually directly controlled by their passengers, which makes energy consumption
highly variable and difficult to predict. New ‘smart’ call systems are being introduced but increasingly
these are being gamed by users as waiting times grow.
The power demanded by a lift/elevator over a single journey peaks with the actions of accelerating
and braking. Factors such as the number of passengers and the frequency of stops can also
dramatically change the power demanded during operation. Traditionally, energy consumption varies
across the day, with peak periods in the morning, lunchtime and evening demanding more power
than at night time when lifts largely remain idle20
. Gradually daytime use is becoming more consistent
and energy intensive as working habits change and more journeys are made outside peak hours.
An additional stair journey does not equate to one less lift/elevator journey. Many, if not most, lift/
elevator journeys are shared, although numbers vary dramatically over the course of the working day.
Runs during peak periods tend to transport more passengers but stop at more floors. Journeys that
stop and start demand more power as do journeys in which the elevator carriage is not optimally
weighted. An increase in inter-floor journeys in many buildings - again caused by changing working
habits - is increasing the number of stop-start journeys overall. Lift energy demand in real buildings
depends on these and other factors, but can be broadly summed-up as:
20 Peters R, et al, Elevator World, Lift Passenger Demand in Office Demand, 2011
14. Smarter Buildings Study - 2016 | 14
• choice of lift/elevator technology21
• building layout22
• users travel habits22
To get credible baseline data, we directly recorded energy demand for the three main classes
of lift mechanism using a data-logger in real buildings. Hydraulic, geared traction and gearless
traction mechanisms were selected as they are the most ubiquitous categories of lift operating
today and there are known differences in efficiency between each23
. This allowed us to develop an
understanding of both the energy savings to be realised from the least efficient systems, as well as an
understanding of how significant the margin might be on the most efficient lift/elevator systems.
See Table 2 overleaf.
The geared and gearless traction lifts were chosen to encompass the range in energy consumption
across all traction mechanisms in use today, where the motors chosen represent the upper and lower
margins of efficiency. The recorded average energy consumptions for both of these traction systems
were transposed onto the real lift traffic pattern of a seven-storey building to allow direct comparison
of their efficiencies. Any traction elevator system in a medium-to-tall building will reside in the range
defined by this study. Hydraulic lifts are rare in buildings taller than four storeys as they become very
inefficient, slow and have high installation costs24
. For this reason, it was reasonable to only model a
single building and lift mechanism.
Measurements were carried out by SVM Associates staff at UK office buildings to generate three lift
energy models. These offices were:
• A seven-storey (excluding ground) building with three gearless traction lifts, serving 460
employees
• A seven-storey (excluding ground) building with three geared traction lifts, serving 460
employees
• A two-storey (excluding ground) building with two hydraulic lifts, serving 410 employees
The energy consumption of lifts in the baseline scenarios has been derived from the original energy
surveys conducted by SVM Associates. All data were modelled using Elevate software and SVM’s
large, unique database of lift energy profiles recorded in real buildings. Elevate simulates how lifts
serve passengers and allows analysts to alter variables to create different scenarios of passenger
demand. We used Elevate to calculate lift energy consumptions and savings according to increased
stair passenger traffic.

A brief history of Lifts
• The ancient Greek polymath Archimedes is credited with inventing the
lift. The Romans adopted it to unleash wild animals into the Colosseum
and Louis XV of France installed one to allow his mistresses to pay private
visits undetected
• The industrial revolution laid the foundations for mechanical lifts. In 1823,
Burton and Hormer developed a steam-powered mechanism for tourists in
London
• In 1835, Stutt and Frost improved safety and efficiency by adding a belt
and counter-balance.
• Elisha Otis, considered ‘the father of the modern elevator’, invented the
‘safety hoist’ in 1854 that prevented accidents if cables snapped. This more
fully addressed safety concerns and paved the way for the ubiquity of lifts
in modern buildings.
• In 1880, German engineer Werner von Siemens pioneered electric motors
in elevators, allowing faster and higher journeys than previous systems.
• The fundamental mechanisms powering lifts have not changed in more
than a century. New systems focus on minimising lift machinery space,
improving comfort, and energy efficiency.

Existing lift energy models
For estimating a lift system’s energy consumption, lift manufacturers and facilities managers accept
guidelines on lift energy consumption drawn up by the Association of German Engineers.These
guidelines - known as VDI 4707- transparently and comprehensively compare different lift systems’
energy consumption according to a set of common, simple-to-apply criteria25
. All lift manufacturers
are now expected to complete an assessment for their products.
VDI 4707 assigns lifts a rating from A to F (where A is best), similar to ratings given to domestic
appliances. The rating is derived from:
• Usage Category: How intensely the lift is used (based on the time spent travelling and standby
per day)
• Travel Demand: How much energy lift journeys require (power used in a single top to bottom
lift cycle with an empty car)
• Standby Demand: How much energy is required in standby mode (measured when the lift is
stationary for 5 minutes)
Using the VDI 4707 standards, the lifts we analysed fell into the following categories:
• gearless traction system - category A
• geared traction system - category C
• hydraulic system - category G
These classes are consistent with other research which states that category A can only be realistically
achieved with a regenerative drive – which is present in our gearless model26
.
The final output of the VDI 4707 assessment is a metric for a lift’s annual energy consumption known
as the “Specific Total Energy Demand”. This is derived from the usage category, travel demand and
standby demand.
VDI 4707 takes direct power measurements allowing comparison of different lift systems in their
real settings. However, these are derived from an artificial and idealised scenario. This stems largely
from the fact that passenger traffic is poorly accounted for by the “usage category”, leading to
underestimates in travel demand energy consumption27
.
The assessments are intended to be building-specific. However, manufacturers are allowed to
complete lift assessments under idealised circumstances which, while comparable, poorly reflect how
their products actually perform in real buildings.

18. Smarter Buildings Study - 2016 | 18
VDI 4707 calculates lift energy based on a single lift. In the buildings served by the geared and
gearless traction elevators, the lift in question was part of a group of three lift cars. In the hydraulic
elevator building, the lift was one of a duplex pair. To be consistent with our baseline model’s outputs,
we have scaled up the outputs of the energy results accordingly.
Determining the effects of stair use
We set out to determine how incentivising people in a building to climb the stairs affects lift use and
consequent savings in terms of energy, costs and carbon emissions. A number of scenarios were used
to illustrate increasing stair climb engagement. More people climbing the stairs affects lift use in
terms of:
• Reducing the number of lift journeys taken
• Reducing the weight carried by lifts (and therefore the power demand of hydraulic lifts; the
weight: power relationship is more complicated in traction lifts due to their counterbalance28
)
• Reducing the number/frequency of stops on lift journeys (and therefore the power required to
accelerate and brake)
The layout, lift properties and population parameters of the real office buildings were fed into Elevate
to create the stair climb scenarios for each building modelled.
SVM Associates analysts used StepJockey’s unique set of stair climbing data to generate a realistic
representation of stair factor. This ‘stair factor’ (the probability of stair use in terms of the proportion
of all up journeys and all down journeys) was then modified within these stair climb scenarios to
quantify the effect of increasing the proportion of stair users in each building compared to baseline
stair use.
The StepJockey data used to generate stair factors was derived from a combination of original
research, including assumptions about best practice, and gamified stair climb data taken from real
buildings.
To calculate the savings resulting from incentivising stair use we subtracted the annual consumption
output of each stair climb scenario from the equivalent baseline output for all lift types. These
scenarios of stair climb engagement fall into two categories: installing signs and running stair
climbing challenges.
Installing signs
We created scenarios to look at lift energy usage and carbon emissions after stair climbing prompts
had been installed. StepJockey Smart Prompts display messages promoting the health benefits of
stair climbing and point out stairwells from salient locations, particularly lift lobbies. The evidence
base for the use of stair prompts to increase stair use in multi-storey buildings is extensive29
.

19. Smarter Buildings Study - 2016 | 19
Running challenges
Separately, we created a range of scenarios to look at lift energy usage and carbon emissions after
not only stair climbing prompts had been installed but after stair climbing had been “gamified”.
Gamification incentivises stair use by adding a competitive element, and this has a significant effect
on the proportion of people climbing the stairs30
. Participants in a building’s gamification initiative
join teams to compete and collaborate in climbing the highest cumulative distance during challenges.
Research into gamification of stair climbing shows that not only does it encourage more stair climbs,
but it also tends to push people to make longer stair climbs. In an eight-floor example building, 16%
of all stair journeys cover a distance of eight floors which would be rare in a building that did not
have stair prompts or gamification.
Model assumptions and justifications
Gamified stair climbing engagement varies in offices because of building layouts, office culture and
working practices. To account for these we ran our models at several levels of engagement.
In the hydraulic lift scenarios, the number of floors climbed was constant because the building was
only two storeys high. We believed this was a reasonable assumption as the proportion of stair
climbers will not directly affect the distance a user is likely to travel in a low-rise building.
In the geared and gearless traction lift/elevator scenarios, the number of floors climbed increases
with signage and challenges. These scenarios are in high-rise31
buildings, so our model assumes users
who have been influenced by stair prompts are more likely to climb and if they do, to climb more
floors per journey.

Results
Real-world versus VDI 4707 predicted energy use
Specific Total Energy Demand as predicted by VDI 4707 was significantly below actual energy use in
all scenarios. The differences between the estimates of VDI 4707 energy outputs compared with the
outputs generated from our model are shown in fig. 1 below.
The VDI 4707 baseline scenario finds that a geared traction system with three lifts demands 63,636
kWh of energy a year compared to the 98,852 kWh described by our model. Thus the VDI 4707
standard is underestimating energy demand from this lift system by 36%.
For the gearless traction system, VDI 4707 states baseline energy consumption is 14,716 kWh
compared to 19,862 kWh from our model, a 26% underestimate.
Finally, for the two-lift hydraulic system there is a 16% difference between the baseline outputs for
VDI 4707 (121,978 kWh) and our model (145,130 kWh).

Impact of stair use on energy consumption
Increased stair use was found to translate into energy savings in all buildings. The modelled scenarios
fall into three broad categories:
• Baseline - no stair climbing intervention
• Signs - visual stair prompts put in place to nudge staff to take the stairs
• Gamification - in addition to signs, building users are motivated and rewarded by forming
teams to climb the stairs to achieve a shared goal
The baseline scenario represents a typical office building with no stair climbing incentives. The
stairwells are used, but their uptake is low. All of the subsequent stair climb scenarios have been
compared against this benchmark. Results were as follows:

Intuitively, increasing the proportion of stair climbers always increases the energy saved through
avoiding lifts although not by a simple linear relationship. Lift energy is a complex parameter that
depends on many variables and which changes from building to building32
.
Assuming a midpoint engagement scenario for each building and lift mechanism, stair promotion
schemes can be conservatively predicted to deliver the following energy/carbon savings:
• Three-floor building with a hydraulic lift system: saves 33,003 kWh of energy and 15,254 kg of
CO2 annually.
• Eight-floor building with a geared traction lift system: saves 23,567 kWh of energy and 10,892
kg of CO2 annually.
• Eight-floor building with a gearless traction lift system: saves 2,724 kWh of energy and 1,259 kg
of CO2 annually.
Total estimated returns (energy, health, time)
To estimate net financial savings we combined the predicted energy savings above with estimates of
the time and health savings stair-climbing initiatives are estimated to deliver, minus installation and
running costs of stair prompts and gamification.
The ROI calculation at Table 4 below borrows from the Physical Activity Business Case Tool
developed by the UK National Institute for Health and Care Excellence (NICE). For each element, we
have looked to the published evidence and applied those findings conservatively.

Which is faster:
man or machine?
• We know driving, motorcycling and pedal-cycling are all faster than
walking. You’d be forgiven for imaging the same is true for lift journeys.
• In fact, the opposite is the case for the majority of lift journeys. Waiting for
lifts and intermediate stops to pick up and drop off other passengers all
add up.
• In 2010, IBM surveyed office workers across 16 US cities and found that
they waited for lifts for an estimated combined total of 92 years that year
• A separate 2011 study in a Canadian Hospital found staff could save
15 minutes of their working day by using stairs instead of waiting for
elevators.
• Time savings are most extreme for short stair journeys but - on average -
taking the stairs is quicker for all journeys up to 7 floors in most buildings
• The realisation that stair use saves time may explain why it is a form of
movement that can quickly become habitual
26. Smarter Buildings Study - 2016 | 26
Table 4: Projected financial savings by building type (energy, health, time)
Basis of calculations
Time savings: High-quality research published by the Canadian Medical Association shows it is on
average quicker taking the stairs than waiting for a lift/elevator for journeys of up to seven floors.
The study found that workers saved 3% of their time, equating to 15 minutes each per day, in a busy
Canadian hospital by taking the stairs. Office staff are less active so we assume a benefit of just 1.5
minutes saved per day for those substituting lift/elevator use with stair use via StepJockey.
Health savings. Sickness absence costs UK businesses over £20 billion a year. According to the
National Institute for Health and Care Excellence (NICE), physical activity programmes at work have
been found to reduce absenteeism, with physically active workers taking 27% fewer sick days. We
assume 1/4th of this benefit.
Assumed values. 230 working days per year; 7.5 hours working per day, average salary £25,000
Non-quantifiable benefits
Evidence suggests physical activity programmes result in a number of other, less tangible, benefits
for which is it not possible to calculate a monetary value. Examples are included below and taken
from the National Institute of Health and Care Excellence (NICE).
Staff retention Staff turnover is expensive. The average recruitment cost per employee is £7,750
(accounting for cover for the vacancy and additional training the new recruit needs). Average annual
turnover among employees in the UK is over 15%. Well-designed wellness programmes can increase
employee job satisfaction and reduce staff turnover by between 10% and 25%.

Productivity Reduced performance and productivity at work due to ill health (‘presenteeism’)
could cost employers two to seven times more than absenteeism. Productivity levels, both in terms
of presenteeism and in general, have been found to increase after the implementation of wellness
programmes.
Team working Organisations that have implemented physical activity programmes have seen an
improvement in team working and communications between different departments, as teams learn to
interact more effectively. Stair-use promotion encourages people flow and face-to-face interactions.
Reputation A well-designed wellness programme can help improve the organisation’s external
reputation, so helping to attract and retain quality staff. Being an ‘employer of choice’ is a powerful
way to attract talented people in a competitive recruitment market.

Gaming ‘smart’ call systems
So-called ‘smart’ lift call systems have become de rigueur in modern high-
rise buildings. Rather than passengers calling the lift, they hit a button desig-
nating the floor number they are travelling to. While this should in principle
allow the lift system to more optimally schedule journeys, in practice ‘smart’
lifts are increasingly being gamed:
Trick 1: Repeatedly calling a lift to a certain floor gives the impression that
several people wish to make the same journey. Thinking it’s being
helpful and about to collect an optimum load the system gives the
lone caller priority.
Trick 2: Pushing the button for a destination floor, plus several floors above
has a similar effect. Several lifts will head your way, thinking there’s a
crowd. Your journey will not just be quiet but uninterrupted.
Trick 3: Allowing groups of visitors new to the building to feel it is enough
to push the button just once for their floor. Meanwhile, initiate trick 1
above for yourself.

Discussion
Comparison with accepted VDI 4707 standard
VDI 4707 is, by its very nature, a simplification of lift energy demand as it provides a common set
of guidelines to calculate and compare the efficiencies of lift systems33
. The concern, however, as
demonstrated by our results, is that it consistently underestimates lift energy compared to real
building use.
The reason for this underestimation is that the three calculations that form the basis of this
assessment poorly reflect the real-life performance of lifts.
Specific energy demand
VDI 4707 determines a lift’s running energy based on a single top to bottom run divided by the run
distance and the lift car’s rated load. This value is then multiplied by two different arbitrary constants
for hydraulic or traction systems.
This is a problem because in real buildings, lifts typically stop at several floors during a run cycle,
picking up and dropping off passengers. This changes the load in a lift car and results in spikes in
power demand for each stop as lifts use the most energy during acceleration and deceleration. The
Reference runs used to calculate the VDI ratings don’t account for these energy intensive aspects of
lift use and will always lead to an underestimate of a lift’s energy use33
.
Standby energy
VDI accreditation does not set out to prescribe what features constitute a lift’s standby mode except
that it is determined five minutes after the last trip has ended. This leaves lift manufacturers free to
turn off lights and shut down ventilation systems during this idle measurement which may not be
invoked when the lifts are commissioned .
Lifts sit idle for a large portion of a 24-hour period which acts to exaggerate the idle energy
inaccuracy. While some may operate a power-down standby mode, it is seldom used during an
extended working day. Lights almost always remain on and ventilation prevents cars from becoming
stuffy34
. This tends towards an underestimate of lift energy consumption in the VDI model compared
with what actually happens.
Usage category
The usage category represents the number of hours a lift is running compared to standby. This
is a gross oversimplification of passenger traffic. Due to its coarseness it is an ineffective way to
33 Thumm G, Lift Report, Energy Efficiency of Lift Systems - Comparison on Basis of VDI 4707, 2009
34 Thumm G, Lift Report, Energy Efficiency of Lift Systems - Comparison on Basis of VDI 4707, 2009
31. Smarter Buildings Study - 2016 | 31
categorise the frequency of lift use and the travel pattern of its users.
Faster lifts fall into a lower usage category simply because they run for less time and typically require
more energy. Two identical lift systems would also have different running times and would require
very different amounts of power if one is stopping at every floor, and the other is set to run express
from the ground to the top of the building45
.
Lift energy consumption in real buildings
The annual energy consumption data given are an assessment of how lifts perform in real buildings
and factors-in the effects of building layout, passenger traffic, acceleration, deceleration and idle
periods in its calculation.
Put in this context, hydraulic lifts still remain substantially less efficient than geared and gearless
mechanisms, consuming 47% and 631% more energy respectively. Despite this, all mechanisms
require significant amounts of energy and costs - enough to demand the attention of any facilities
manager. In the three medium-sized office building scenarios, containing about 400 employees each,
the lift systems cost between £2,754 and £20,122 a year and on average released 40,000kg of CO2.
One would typically expect lift energy to be a greater concern for facilities managers in tall buildings
and skyscrapers because they will be used more frequently and take longer runs. However, our data
show that managers of low-rise buildings, which commonly house hydraulic lifts, should also pay
close attention. Hydraulic lift efficiency is so poor that these systems actually consume comparatively
more electricity than the traction examples housed in taller buildings.

non-domestic buildings
are nearly four times
their design estimate.
33. Smarter Buildings Study - 2016 | 33
Conclusions
Inefficiency in buildings’ systems is a headache for all property and facilities businesses.
When the causes of inefficiency are known they can either be dealt with (and costs and emissions
saved), or accepted (if capital outlay for refurbishments are unacceptably high). But problems are
compounded when the causes of inefficiency are barely glimpsed - as is clearly the case in the
energy consumption of lifts/elevators.
It is well-known that not all lift systems are equally efficient. It’s also well-known that different
building layouts and use can greatly affect the amount of energy a lift uses in a year. Industry
guidelines help. But what has not been clear, until now, is the potential variation in lift energy
consumption based simply on the difference between industry standard models and real-world
demands.
Some readers will be sceptical about our findings. And they’d be right to if our findings were raising
this problem for the first time and in isolation. But they’re not. As recently as February 2016, the
government agency Innovate UK found similar discrepancies between the claims made for green
buildings and their real-world performance35
.
Innovate UK found that in non-domestic buildings carbon emissions were typically 3.8 times higher
than the average design estimate, with the worst example being 10 times higher. In addition only one
of the 49 buildings monitored had carbon emissions which actually matched the design estimates.
Innovate’s study echoes the results of this report. In all of the lift scenarios studied, real energy
consumption exceeded the official VDI 4707 estimates by between 16% and 36%.
On a more positive note, it is clear from the study data that much if not all the excess energy being
used by lifts/elevators can be mitigated through the use of easily implemented stair promotion
schemes. In all scenarios, stair promotion decreased lift/elevator use significantly.
The benefits resulting from such a switch are not confined to energy/carbon savings - although
these were not insignificant. When time and projected health savings are taken into account, stair
promotion initiatives appear to generate quite large and predictable monetary savings year-on-year.
There are also a clear set of non-quantifiable savings to be gained from nudging a proportion of a
building’s occupants to use the stairs. These are detailed above but perhaps the most significant in
light of the new health standards for offices being introduced is that they will enable property owners
and managers to score well in such standards without heavy capital outlay.
Stairs are common to all office buildings and are an asset that has already been paid for. Sweating
them therefore makes excellent economic as well as practical sense.

Case study:
Merton London Borough
Council
When the lifts at the iconic Civic Centre in Morden, south London, were going
to be refurbished, Merton Council’s Public Health team saw an opportunity to
kill two birds with one stone.
The council - which looks after services for more than 200,000 people in an
ethnically diverse part of London - wanted to engage staff to use the stairs
so they could boost their health and reduce pressure on the lifts.
Merton implemented StepJockey signs and launched a stair climbing
challenge to get staff to ‘climb Mount Everest’ together. In just a month, they
had scaled the equivalent of the world’s tallest mountain on the stairs and
burnt 74,223 calories.
“We needed a way to encourage our staff away from the lifts and onto the
stairs not only because some of the lifts needed renovating, but also because
we wanted to improve our staff’s health and wellbeing”, said Barry Causer,
Public Health Commissioning Manager. “It worked well for both.”
