None
A brief description of when and why the building energy consumption baseline was adopted:
The baseline year corresponds to the baseline year of the University's climate action plan.
None
A brief description of any building temperature standards employed by the institution:
The standard discharge air temperature is 55 degrees Fahrenheit. The occupied cooling set-point is 74 degrees Fahrenheit and the occupied heating set-point is 68 degrees Fahrenheit.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
Noribachi LED lights in fieldhouse, LED lights in performing arts building
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Occupancy sensors are
used to control lighting in meeting rooms, offices, and restrooms in all new and renovated buildings.
None
A brief description of any passive solar heating employed by the institution:
passive solar heating that provides hot water needs for small residential unit
None
A brief description of any ground-source heat pumps employed by the institution:
none
None
A brief description of any cogeneration technologies employed by the institution:
Bucknell operates a highly efficient natural gas co-gen plant that was installed in 1998. The plant reduced greenhouse gas emissions by 40%.
None
A brief description of any building recommissioning or retrofit program employed by the institution:
The lights in the fieldhouse were retrofitted with LED lights as well as the lights in the performing arts building. The kitchen hoods in the dining areas were retrofitted with a system that allows the fan speed to adjust accordingly to usage. Additionally, the HVAC system in a science building was replaced and heating pumps in the gymnasium were converted to VFDs instead of constant speed drives. Another building was added to the buildings on campus that are automatically controlled so that it can be scheduled when occupied.
None
A brief description of any energy metering and management systems employed by the institution:
WebCTRL, a program distributed by Automated Logic Corporation, shows the electric, chilled water and steam meters for buildings around campus. These are monitored monthly. Additionally, the buildings are scheduled to unoccupied mode when there are no events so that the room temperature is allowed to setback. This allows the equipment to slow down or stop running for a period of time.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
none
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
The engineering building as well as the new LEED certified building have green roofs.
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
VendingMizer occupancy sensors
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
Analytika is a program that evaluates the data from the automated controls system and lists the problems each building is experiencing. This helps formulate work orders so that machinery does not continue to operate inefficiently.
None
