A brief description of when and why the building energy consumption baseline was adopted:
A brief description of any building temperature standards employed by the institution:
A brief description of any light emitting diode (LED) lighting employed by the institution:
We use over 100 LED lights at Chatham University, with a variety of indoor usages for common areas and elevators and some of our offices. We also use 46 watt LEDs in outdoor lighting to replace the 250 watt metal halide units.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Chatham University has lighting sensors in all of our classrooms and hallways at our Eastside campus and in most major classrooms at the Shadyside campus to reduce energy when rooms are unoccupied.
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:
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:
A brief description of any energy metering and management systems employed by the institution:
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
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:
Rather than have on-off motion sensors, we have turned permanently off the lighting in the vending machines.
A brief description of other energy conservation and efficiency initiatives employed by the institution:
