2. Almost 40 percent of the total energy consumption goes into
buildings. Above one-third is used for space and water heating
and the rest for cooling, ventilation and artificial lighting. Simple
mathematics show, and society broadly agrees, that the use of
fossil fuels needs to be reduced and eliminated on the long term.
Energy efficiency and conservation in public and private buildings
will therefore be more and more important on the medium term.
However, economics is not the only reason. Improving energy
efficiency in buildings is one of the key measures for tackling
energy supply and environmental problems and reaching our CO2
reduction targets by 2020.
The statutory and regulatory framework has been established
by the European Parliament (EN 15232) and by the German fed-
eral government in the form of the Energy Conservation Regula-
tions (EnEV) from 2002. These regulations define the evaluation
guidelines to be used in drawing up an energy balance sheet for
residential buildings, including technical systems. The 2007 edi-
tion of the EnEV regulations extends its scope to non-residential
buildings and makes energy certification a requirement for exist-
ing buildings. EnEV 2009, effective since October 1st, 2009, has
tightened up the energy requirements for buildings by 30 per-
cent, with a further 30 percent tightening planned by 2012.
As the Scottish physicist Sir William Thomson, later Lord Kelvin,
once said, “If you cannot measure it, you cannot improve it.” Only
if you have the ability to capture, analyse and evaluate your en-
ergy consumption data on the long term you will have a chance to
identify potential savings and to introduce appropriate conserva-
tion measures. To make this happen you need to bring all your en-
ergy-related data together in one central platform. Benchmark-
ing for a wide variety of building types and uses (e.g. including
hotels, hospitals, schools or office buildings) helps to take action
for a better level of energy efficiency.
Finally, we have to invest in the energy assessment of our living
and working spaces to know the specific energy consumption. As
we are aware of the fuel consumption of our car, we have to be
able to give the answer to the question: ‘What is the energy con-
sumption of your building per square meter ?’
“In the same way as we today know the fuel consumption of our car, will we have to be able to answer the question,
‘What is the energy consumption of your building per square meter?’ in the future.”

e3m is the core component of a continuous optimisation process. Its complex statistical
analysis capabilities gives you a choice of comparative options using benchmarks, direct
comparisons or long-term analysis.
Using this technology, e3m users can save up to 40 per cent in energy costs.
shows potential savings
>
e3m is much more than just capturing data – it offers built-in alert functions, tenant
modelling, local visualisation, on/off timer programming and more. e3m is available both
as a classic on-site installation and as an online service. It’s your choice whether to buy
a conventional licence or take the Software as a Service option.
is flexible and modular
>
makes energy consumption transparent
> e3m is the professional solution for analysing the energy consumption of your property.
Choose from a selection of standard reports, or use the intuitive interface to make cus-
tomised data queries.
e3m processes the raw data to generate key figures. Thanks to a powerful database engine,
coupled with web technology, the data is available anywhere at the touch of a button.
e3m is well suited from single use in one office building to distributed applications for
property managers and chain businesses. e3m allows open integration of external sys-
tems at both individual property level (DDCs and building control software) and centrally
(asset and facility management software).
4. The e3m Data Center allows you to centrally manage the relevant key figures for
your properties. This is where all the data comes together. It lets you perform
various analyses covering everything from process optimisation and energy ma-
nagement to maintenance and repairs.
Your web browser is the universal front
end for e3m. Thin Client Technology gives
you access to all data and configurations
in the e3m Data Center from any location.
Features/Modules:
• Display and configuration of
e3m Data Center
• Managing and monitoring
the e3m portal

• Web 2.0 AJAX technology
e3m is a scalable energy data management system, which can be deployed either as Software as a Service or locally as a system solu-
tion. It enables you to centrally manage and analyse meter data, key figures and reference values for your properties at local, national
or global level. As a result, you’ll be in a position to create a continuous information flow, from data capturing through
to financial accounting.
Features/Modules:
• Capturing, storing and processing data
• Overall alert and fault management
• Management of metered and
reference values
• Manual entry of meter readings
• Data verification and correction
• Location and tenant management
• Document management
• Automatic data aggregation
• Load profile management
• Key figures, e.g. electricity or heat
consumption by area, CO2
emissions
by area
• Benchmarking and energy certification

Case Study
Migros is Switzerland’s biggest retailer and also has branches in southern Germany and France. The Migros group comprises over 50 busi-
nesses and is a cooperative with approx. two million members. In 2008 the group employed over 84,000 people and reported sales of
CHF 25.75 billion and profits of CHF 701 million. The e3m energy management solution was introduced across the board in two of the
cooperative businesses. Inside Migros e3m technology is known as MESA.

Environment
Energy
Efficiency
Management
– The Logo
>The idea for the logo came to us quite naturally in an attempt to
define the concept of energy management. A management process
consists of four phases: goal setting, planning, implementation
and review. So what has to be considered ?
It’s all about energy and using it in a responsible way. That im-
plies that beside the economic aspects, the environment also
has to play a role. Reduced CO2
emissions are not only good for
the environment; they also have clear financial benefits. It’s an
undisputed fact that environment-friendly energy is the energy
we don’t consume. Energy efficiency means achieving a desired
benefit with the lowest possible energy input.
The three concepts – energy, environment and efficiency – appear
in our logo as the subject of the management process.
