A brief description of when and why the building energy consumption baseline was adopted:
This is the standard baseline date for all sustainability reporting at Loyola.
A brief description of any building temperature standards employed by the institution:
Loyola's Information Commons uses a Building Automation System (BAS) that divides the seasons into Winter and Summer and monitors indoor and outdoor conditions to react accordingly. In Winter (whenever the the temperature falls below 55 degrees Fahrenheit), space is maintained at approximately 71 degrees. In Summer, the air handlers turn off and windows open when the temperature is between 55 and 68 degrees. When the temperature is above 74 degrees, the air handlers start circulating air.
A brief description of any light emitting diode (LED) lighting employed by the institution:
Loyola is upgrading many of its buildings with energy-efficient technologies, such as energy management systems, heat recovery systems, LED lighting, and lighting sensors. Recently, Loyola completed a major conversion from HID to LED for outdoor lighting fixtures across campus.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Loyola's Information Commons uses sensors that monitor light and only turn on the energy-efficient fluorescent lights when they are needed. When rooms are unoccupied, the lights remain off. The Quinlan Life Sciences Education and Research Center also uses motion-sensor lighting.
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:
N/A
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:
Through Delta Controls we have a building automation system that includes energy management, demand response and emergency operations.
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:
A brief description of other energy conservation and efficiency initiatives employed by the institution:
