Sustainability at Case Western Reserve University
The sustainability program at Case Western Reserve University encompasses most, if not all, areas of operations,
teaching, and research. Our goal is to infuse sustainability into the classroom, the office, the mechanical rooms, and
the residence halls. The University is a signatory to the American College and University Presidents Climate
Commitment (ACUPCC) and has declared our intention to move the University toward climate (and carbon) neutrality.
We have calculated our GHG emissions (our carbon footprint) at roughly 250,000 metric tons of Co2e per year. The
University is in the initial stages of developing and implementing a “Climate Action Plan” which will be the living
document of mitigation strategies and projects which will move us to neutrality.
This document is intended to highlight many of the various components of our program which we feel are easily
replicable on any campus, or facility. We are focused on reducing consumption of fossil fuel utilities, the conservation
of potable water and the preservation of groundwater aquifers. The components of our program are in various
stages of maturity. Energy conservation has a long and successful history, whereas storm water management is just
getting underway. Renewable energy opportunities are being explored and (soon we hope) implemented. We’ve
constructed our first LEED certified new buildings and now are completing our first LEED certified building renovation.
Lighting:
We have completed our first generation of lighting retrofits. Most (if not all) of our incandescent lamps have been
replaced with compact fluorescent lamps. Our 2x4 and 2x2 lay in fixtures have all been retrofitted with electronic
ballasts and T‐8 lamps. We’re retrofitting the Pathology building which is one of the last to be completed. Motion
sensors are installed in corridors, and daylight sensors have been installed in some specific buildings. We have now
begun to move into the extensive use of LED lamps and fixtures. We have determined that lights in certain locations,
namely building entrances, stairwells, and elevator cabs must remain on 24 hours a day and therefore represent a
“base lighting load” for each facility. We have concentrated our efforts on these areas first.

We’ve also begun to install 30 watt 2’x2’ LED fixtures in corridors.

Several facilities have their lighting systems connected to the Campus energy management system and are controlled by a preset program.
Motors and Variable Frequency Drives:
Throughout most of our major air handling systems we have retrofitted all motors larger than 5 horsepower with high efficiency models. Combined with variable speed drives the energy reduction can be as much as 30‐50%.

The Mandel School of Applied Social Science is a building that received a comprehensive group of energy
conservation measures. All AHU motors were retrofitted, VFD’s were installed on all motors, VAV box controls were
all upgraded , and a 30 year old chiller was retired and a district chilled water line was installed. The total project cost
was $300,000. The utiltiy savings has averaged $50,000 per year for a simple payback of 6 years.
Domestic Water:
Two significant water saving projects that have been implemented are the condensate capture system and the “pint”
urinals.
5
The pint urinals use only 16 ounces per flush compared to the standard 1 gallon per flush. These urinals will become
the standard for the campus
The condensate capture system is a low cost installation that makes use of previously discarded condensate from
AHU’s. In the three years since the installation the smallest of the 7 systems we’ve installed, has generated nearly
350,000 gallons of water. This water was returned to the sump of the chilled water system cooling tower on the roof
of the building.
We’ve also installed closed loop heat rejection systems in lieu of “once through” domestic water systems.
6
Extensive use of touch less faucets and water conserving toilets, throughout the campus, represents a substantial
reduction in domestic water consumption.
Storm Water Management:
The Northeast Ohio Regional Sewer District is about to impose a storm water surcharge for every 3,000 square feet of
impervious surface on a property. For organizations such as colleges and universities this can amount to a substantial
cost. Organizations can receive credits for any areas that qualify as pervious. Storm water management strategies
include pervious concrete‐ pavers‐ and asphalt, vegetative roofs, ground water recharge, rain barrels, cisterns, and
bio‐swales.
Pervious concrete sidewalk Groundwater recharge
Rain from buildings and garage is piped to football field
where it drains back to the earth.
Steam and Chilled Water:
Replace missing and damaged insulation on all HHW, Steam and CHW lines.
Demand control ventilation systems. DDC control system which use a “sensor suite” to sense the presence of CO2
and a variety of VOC’s which may be present in a laboratory. If the system senses no CO2 and no VOC’s it closes the
VAV box to the lab, reducing the air changes.
“Close the Sash” program uses magnetic stickers to remind lab staff to close hood sashes when not in use and at the
end of the day.

Transportation:
The University is converting the maintenance truck fleet to electric powered vehicles. These vehicles cost
approximately $600 per year to operate compared to approximately $2,000 for fuel and maintenance costs for a fossil
fuel vehicle.

Throughout the University there are several centers, programs, institutes and student rune associations and chapters that
emphasize sustainability and social equity/justice.
