A brief description of when and why the building energy consumption baseline was adopted:
Building baseline chosen because it represented a high energy use period.
A brief description of any building temperature standards employed by the institution:
The New Science, Trumbower, Shankweiler, Seegers, Trexler Pavilion and Moyer buildings all work under the Niagara/Tridium Building Automation System. Set back temperatures are scheduled through the Tridium BAS based on building occupancy
Life Sports Center operates under Johnson M3 Building Automation System. Set back temperatures are scheduled through the M3 BAS based on building occupancy
The Trexler Library operates under Johnson Metasys Building Automation System. Set back temperatures are scheduled through the Metasys BAS based on building occupancy
Ettinger and Haas buildings operate under Andover Building Automation System. Set back temperatures are scheduled through the Andover BAS based on building occupancy
As of March 2012 all major buildings utilize timer technology
A brief description of any light emitting diode (LED) lighting employed by the institution:
Muhlenberg College uses Light Emitting Diode (LED) technology in at least one lighting application. (LED applications in exit signs and remote controls do not count for this credit.)
LED lighting is only being used in fire extinguisher cabinets
March 2012, LED lighting has been installed in the newly built “light lounge” in Seegers Union and LED theatrical lighting instruments are utilized by the Department of Theatre and Dance. LED lighting is being used for three test lamp posts and lighting in the Hillel/ Sociology/ Anthropology building dining room and classroom.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Muhlenberg College uses motion, infrared, and/or light sensors to reduce energy use for lighting in at least one building.
We are using motion occupancy sensors for lighting in the restrooms of Ettinger, Moyer, Haas, Trumbower and New Science.
The New Science building has a programmable lighting control system that enables us to schedule lighting shut downs
All exterior lighting is on Photocell technology
March 2012, all major buildings have lighting sensors in at least one room
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:
Muhlenberg College does not use a centralized energy management system that allows the College to track energy consumption and performance in multiple buildings in a central location.
We are using a few different management systems on campus such as Johnson Metasys, M3, Tridium, E-Mon, and Andover. The systems allow us to operate equipment, schedule setbacks and trend data. We are working toward utilizing 1 BAS overlay that will bring all of these systems under one data-base.
As of March 2012 Muhlenberg has installed a centralized system to monitor a variety of buildings. Legacy systems are still used as well. The new rehearsal house is tied into this central system.
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:
At least one machine on campus has a sensor to cycle the refrigeration compressor on and off.
A brief description of other energy conservation and efficiency initiatives employed by the institution:
