A brief description of when and why the building energy consumption baseline was adopted:

Villanova signed the Presidents Climate Commitment in 2007. As part of the commitment we were required to choose a baseline year to compare our carbon emission reduction progress to. The year we chose is the academic year from 2007 to 2008. This year was adopted because it was the same year we signed the Presidents Climate Commitment.

A brief description of any building temperature standards employed by the institution:

Our building engineers are told to design our buildings, and their HVAC systems to meet ASHRAE. Building temperature set points fluctuate throughout the campus depending on building function and occupant comfort level.

A brief description of any light emitting diode (LED) lighting employed by the institution:

The University retrofits lighting to LED when lamps are being upgraded due to aesthetics, function, or age. All exit lighting is LED powered, and there has been an effort to use LED in outdoor and 24 hour lighting. Other applications include athletic facilities, library stacks, classrooms, and office space.

A brief description of any occupancy and/or vacancy sensors employed by the institution:

As we renovate offices, classrooms, and public areas the University retrofits the areas with switch sensors (Infrared and ultra sound) , occupancy sensors or vacancy sensors depending on the space use type.

A brief description of any passive solar heating employed by the institution:


A brief description of any ground-source heat pumps employed by the institution:

One dormitory on campus utilizes a geothermal heating and cooling system to condition 20,000 square feet.

A brief description of any cogeneration technologies employed by the institution:


A brief description of any building recommissioning or retrofit program employed by the institution:

We recently conducted a recommissioning of our largest lab building on campus. Due to its size and energy intensity the savings should prove to be substantial.

A brief description of any energy metering and management systems employed by the institution:

The 5 LEED buildings on campus have sub metering systems for electricity, water and heat. We also have a DVC system that controls many of the buildings on main campus. With this system we are able to reset hot water temperature based on the outside temperature and lower the temperature at night. Additionally, lighting in one of our LEED buildings is managed through the DVC system. Lastly, in our main office building occupancy sensors have been installed that turn down heating and cooling when the room is unoccupied.

A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

When an older appliance breaks they are replaced with newer more efficient appliances. When available we use energy star certified appliances.

A brief description of any energy-efficient landscape design initiatives employed by the institution:


A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
