Currents is the energy conservation newsletter for Thomas Jefferson University. This newsletter highlights energy conservation efforts throughout the enterprise. This issues presents Jefferson's Building Commissioning project with Cimetrics Analytika. Result - energy cost savings of over $1M Dollars, reduction in CO2 from reduced energy use.
Jefferson’s Energy Strategy is to reduce energy costs and reduce energy use
which will lower our carbon footprint. This article describes how we do this
while delivering a world class patient experience.
Energy Use at Jefferson
First, how much energy do we use at Jefferson?
Hospitals generally use energy as shown below:
We are one of the largest energy users in the City of Philadelphia. We spend
over $40 Million a year in energy costs (includes the cost for electricity, natural
gas, steam, water and sewer services). We use over 260 Million kilowatt-hours
(Kwh) of electricity every year.
To get a feel for just how much energy this is, consider your home:
• Energy use for an “average” home in 2017 – 10,400 kilowatt-hours per
year (U.S. Energy Information Administration)
• Jefferson annual electricity use equivalent to 25,000 homes
• Assuming 2.5 people in the “average” home (U.S. Department of
Commerce, Economics and Statistics Administration), our electricity use
each year is equivalent to approximately 62, 500 people
• The population of Harrisburg is approximately 50,000. Therefore,
Jefferson buildings use more electricity each year than all of the homes in
the City of Harrisburg.
The Energy Conser vation Newsletter • W I N T E R 2019
Welcome to our Jefferson
Currents Newsletter. This
newsletter will highlight our
energy conservation efforts
throughout the enterprise.
The total energy spend for
Jefferson is now more than
$40 Million per year. The
challenge – how do we
manage this for maximum
savings. The good news –
we have a solid proven plan
for doing this, as described
in this newsletter. But we
need your help.
Every employee in every
Department can help to
reduce our energy costs.

2. Energy Efficiency projects
• Co-generation units were installed
at Abington (2012) and Torresdale
(2016). The Torresdale unit saves
• Long-term energy efficiency
projects conducted in Center
City over the last 18 years are
now saving over $4.4 M/year in
• Installation of a new software
system by Cimetris Inc. to perform
continuous commissioning of
our energy using equipment

(bulbs) with higher efficiency LED
products and also adding over
3000 new occupancy sensors
3. Load Shedding
• Voluntary program for the electrical
“grid” that we are in
• Financially rewards companies that
can reduce their energy use when
needed by the grid…we have
developed a plan to do this, safely
• We receive payments each year for
YOUR Role in Jefferson’s
Energy Management Plan
Energy management and conservation
at Jefferson has two parts:
1. What the Enterprise does to
conserve energy, described above
2. What YOU can do to conserve
You may not realize how important
individual employee energy
conservation is to Jefferson.
We would like to ask everyone to
practice the following energy saving
steps in your everyday job:
1. Turn out lights when not needed in
public spaces such as conference or
2. Close fume hoods when not in use
3. Turn off unused vacuum lines
4. Call in water leaks to 5-6846 for

Jefferson’s Building Commissioning Project
What is Building Commissioning?
• checking and testing (“tune-up”) your building’s energy-
using equipment during design, construction and turnover
to the building owner.
What is Continuous Commissioning?
• checking and testing your equipment continuously, 24/7.
while it is operating.
Buildings change, all the time, in many ways. Interior spaces and
uses can change. Equipment wears down with age and is
oftentimes changed in piecemeal fashion. Active buildings like
ours change quickly. Continuous commissioning helps us know
that our buildings are changing in a way that won’t waste energy,
while increasing occupant comfort at the same time.
Jefferson’s Continuous Commissioning Program
The Jefferson continuous commissioning program began in
March of 2013.
We selected the following team of recognized experts in
continuous commissioning for the project:
• 30-year old Boston-based company that is a leader in
analytics technology for building automation systems
• Recognized leader in continuous commissioning using their
Analytika software, which is now being used by Jefferson.
• A Philadelphia commissioning company that coordinates the
Cimetrics project for us.
• Alex Martinez, the owner of this company, has worked
locally in facilities maintenance and management for over
20 years and has done commissioning work for the past 10
How Does the Jefferson Continuous
Commissioning Program Work?
Before Cimetrics, it was difficult for us to identify building energy
problems because they can easily be “hidden”, such as heating
and cooling an area at the same time.
The Cimetrics program overcomes this with sophisticated
technology developed by Cimetrics.
• The Cimetrics Anaylika software has now been added to our
Siemens building automation system to help identify and
target energy-wasting issues.
• The Cimetrics Analytica process not only helps us find
existing energy wasting problems with our equipment, it can
also “predict” a problem and can identify where a problem
exists but is “hiding”.

Currents WINTER 2019
The Cimetrics program includes:
• The analysis of 18 Center City buildings that have a combined
floor space of almost 4 Million square feet.
• The Cimetrics software analyzes over 76,000 system
operation sampling points in our Siemens Apogee Building
Automation System, (BAS).
• Over 1.2 Million sampling points are evaluated by the
Cimetrics system every day. These sampling points are in:
• 20 Chillers and 4 cooling towers
• 116 pumps
• 247 air handling units
• 100 fume hoods in 200+ lab areas
• 41 operating rooms
• 4,300 exhaust fans
The Cimetrics workflow is a two-part process:
1. Cimetrics Analytika software:
• Determines where a mechanical and control system fault is
occurring that can result in unusual energy use
• Identifies a corrective action for the situation and also
identifies cost factors for the potential problem
• Documents the incident and sends this to Martinez Cx for
2. Martinez Cx and a Jefferson Facilities supervisor
• visit the problem condition or area to confirm or deny the
• If confirmed by Martinez Cx, Jefferson Facilities personnel
correct the problem using the Facilities Department’s work
The final step in the Cimetrics process is a follow-up evaluation of
the repair or correction.
What Have Been the Cimetrics Results So Far?
The Cimetrics program results so far have been:
• Energy cost savings of over $1 Million dollars.
• The reduction in CO2 from our reduced energy use is over
7,000 Metric Tons. This is the equivalent of taking 1500 cars
off the road for a year.
Jefferson continues to sustainably provide its world class patient
experience every day.
Bob Pizzo and Alex Martinez do extensive field checking and verification of
potential energy-using problems with our equipment on a regular basis.
Home Heating Tips for Winter
Heating your home:
• uses more energy and costs more money than any
other system in your home
• typically makes up about 42% of your utility bill.
• No matter what kind of heating system you have in
your house, you can save money and increase your
comfort by properly maintaining and upgrading your
Using a “whole house” plan can save about 30% on your
energy bill while reducing environmental emissions.
Here’s some tips for saving home heating energy costs
• Upgrade ceiling insulation to R-38 (higher R values
mean greater insulation levels and thus more energy
• Insulate exterior heated basement walls to at least
• Set your home thermostat as low as comfortable
(68 F is suggested) when the house is occupied.
• Set back the thermostat by about 8 degrees at night
or when the house is unoccupied during the day.
• Set back the thermostat to 50 to 55 F when the house
is unoccupied for over 24 hours.
• Install a programmable thermostat to automatically
provide the setbacks mentioned above
• Replace furnace filters once a month during the
• Remove any obstructions and clean heating
• During winter, keep the draperies and shades on
your south-facing windows open during the day
to allow the sunlight to enter your home and
closed at night to reduce the chill you may feel
from cold windows.
And if you replace your heating system, remember that
you may be able to get a PECO rebate to help with the
costs. See more information here: www.peco.com/
And finally, here are a fewYouTube video’s on home
heating energy savings that we hope can help you save
your home energy costs:
