A brief description of when and why the building energy consumption baseline was adopted:
2007-08 is the earliest year for which we have good data.
A brief description of any building temperature standards employed by the institution:
Two main systems are used at WPI, about 50/50 mix of Automated Logic and Schneider Continuum, and each resides in own network for safety and security reasons. These systems are part of the building management systems which are used to monitor and control heating and cooling in campus buildings. In addition, Eco-Bees monitors were installed in a portion of the apartment owned by WPI. These devices prevent the heat from being raised higher than 72 degrees.
A brief description of any light emitting diode (LED) lighting employed by the institution:
LED lighting has been incorporated into the lighting systems in the newest residential building, Faraday Hall. In addition, the Campus Center and Gateway Park were retrofitted with LED lighting in 2014.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Motion and CO2 sensors are used in spaces to control lighting and ventilation across campus.
A brief description of any passive solar heating employed by the institution:
South facing glass is employed in the Sports & Recreation Center and window location design was based on the sun path in East Hall.
A brief description of any ground-source heat pumps employed by the institution:
A brief description of any cogeneration technologies employed by the institution:
Tecogen Ultra CM-75 combined heat and power units have been installed at the Life Sciences & Bioengineering Center and the Campus Center.
A brief description of any building recommissioning or retrofit program employed by the institution:
A building recommissioning program was recently completed in two campus buildings, the Campus Center and Life Sciences & Bioengineering Center.
A brief description of any energy metering and management systems employed by the institution:
The Building Management System was reviewed and overhauled in 2012-2013 to improve building heating and cooling efficiencies. Institution-owned apartment buildings were equipped with Eco-Bees monitored thermostats to ensure heating did not exceed 72 degrees. On our campus, the powerhouse has a management system (SCADA recording monitoring system with webalert) specific to steam generation and has government-required reporting. Individual electric meters have been installed in most buildings across campus so that the institution can measure performance and determine areas in need of improvement.
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
WPI purchases Energy-Star rated 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:
Energy miser electronic sensors are used to decrease energy consumption of vending machines.
A brief description of other energy conservation and efficiency initiatives employed by the institution:
