With a growing campus population, the need for academic and student residence
space has increased and this trend is expected to continue in the near future.
Constructing additional buildings typically means more energy consumption.
However, Salisbury University continually strives to improve the efficiency of
existing and new building construction. In addition, an energy manager controls
and optimizes building HVAC systems using an electronic building automation
system. In 2007, a campus wide energy service contract (ESCO) was initiated
which replaced lighting, plumbing fixtures, pumps, chillers and other aging
infrastructure with more efficient equipment.
At a Glance
- SU installed occupancy sensors in
offices and general purpose classrooms of TETC
and Perdue Hall as well as offices in the
Commons and Maintenance Building, helping to
reduce lighting energy consumption lighting when
these spaces are not occupied.
- A solar hot water system was installed
on the roof of Nanticoke Hall during the major
renovation in 2011.
- A student-approved "green fee" was
passed in the spring of 2013 and is in the final
stages of approval.
- SU purchases renewable energy from
solar, wind projects.
- SU completed an energy service
contract (ESCO) which included a variety of
energy conserving projects with guaranteed
energy savings of at least $300,000 per year.
As an energy saving initiative, occupancy sensors are a standard feature in
all new construction and major renovations. These sensors automatically turn
lights off after an area is unoccupied for a set period of time. Occupancy
sensors are estimated to produce a savings of 30%, and are especially effective
in areas which have frequent periods of inactivity. Sensors are now a standard
feature in new construction projects and major renovations and may be observed
throughout TETC and Perdue Hall. In addition, they were installed in offices of
the Commons and Maintenance Building as well as the classrooms within the
Water Solar Array
A solar hot water array was installed on the roof of Nanticoke Hall during
the renovation in 2011. The array consists of a series of glass chambers
surrounding black-painted copper piping with copper flashing. The system
provides a year-round, renewable source of heated water for the domestic hot
water in this residence hall. In addition, the solar hot water was designed to
serve as the heat source for the mechanical room in the basement of Nanticoke.
The Student Government Association passed a resolution for a
student sustainability fee in the spring of 2013 and it is in
the final stages of approval. Once finalized, the fee will fund
a variety of sustainability projects which are proposed by
students and faculty supervisor. Proposals will be evaluated and
awarded by a committee comprised of students, faculty and staff.
Successful participants will present results of their projects
and each will be posted on the sustainability website.
Renewable Energy Purchases
In 2010, the University System of Maryland (USM) and
the Department of General Services executed three (3), twenty
year Power Purchase Agreements for renewable energy. The
- 16 megawatt
solar project at Mount
St. Mary's University
- 10 megawatt
wind project in western
- 55 megawatt wind project in West
SU purchases a percentage of the output from each
project, which equates to approximately 12 percent of our total
electricity use. The Maryland wind project, Roth Rock Wind Farm,
became operational in July 2011, with the Pinnacle Project (West
Virginia) expected to be operational in the first quarter 2012;
and the solar project at Mount St. Mary’s operational later in
Additional renewable energy is purchased under the
Renewable Portfolio Standard (RPS), which is a requirement of
our electricity providers under Maryland law. For 2013,
electricity providers were required to provide renewable energy
equivalent to 10.7% of our consumption. To put this in
perspective, for every 100 kilowatt hours purchased, 10.7
kilowatt hours will be from renewable energy sources. This
percentage will gradually increase until 2022, when it will
Energy Performance Contract
In 2007, Salisbury University partnered with PEPCO Energy
Services to decrease water usage and energy consumption for a
projected $5.3 million savings. PEPCO provided services for 17
projects, including the replacement of aging mechanical
equipment or the installation of more efficient equipment for
heating and cooling in 14 buildings, the installation of tens of
thousands of more energy-efficient bulbs and lighting fixtures
and the installation of energy “misers” on vending machines.
The project also involves upgrading approximately 1,700
plumbing fixtures to conserve 11 million gallons of water
annually and reducing excessive air and solar infiltration to
building interiors in 38 locations.
Funding for the project comes from the guaranteed savings
through the investment, as well as from residence hall
renovation funding. In all, the project is expected to save
water equal to the amount consumed annually by 473 family homes,
electricity sufficient to power 1,600 homes, and will reduce
emissions equal to removing 1,571 cars from the road.
Landfill Gas Power Generation
Ingenco operates an electricity generation station powered by
recovered landfill gas at the Wicomico County landfill. In 2013,
SU purchased 8,000 RECs from the facility to offset emissions
from campus operations. The Wicomico County landfill is the
repository for the solid waste from the campus and supporting
the landfill gas power generation operations is an
environmentally responsible way to reduce the impact of the
solid waste. The estimated landfill gas being destroyed to
produce 8,000 RECs is the environmental equivalent of the annual
greenhouse gas emissions from 7,552 passenger vehicles, the
carbon dioxide emissions from burning 210 railcars of coal or
the energy benefit of powering 539 homes.
