A brief description of when and why the building energy consumption baseline was adopted:

FY11 is the first year the College was able to collect much of the data required for energy and carbon footprint calculations.

A brief description of any building temperature standards employed by the institution:

It is college policy to heat interior spaces during normal occupied hours to a temperature of 68°F - 74°F, which is the established occupied setpoint for the campus during the heating season. Facilities Management recognizes that temperatures will vary within the building and every effort will be made to stay within 3°F of this range. These temperatures will be set by the Energy Manager and Facilities Management using a centralized building control system. Occupants who control their own temperature are asked to adhere to this policy. Please note that temperature readings are taken at the thermostat level.

A brief description of any light emitting diode (LED) lighting employed by the institution:

All newly constructed or renovated buildings are converted to LED lights. Additionally, as light fixtures fail, they are replaced with LED fixtures. The College is currently in the process of evaluating LED replacements for all exterior pole and lantern light fixtures.

A brief description of any occupancy and/or vacancy sensors employed by the institution:

All recently renovated buildings are equipped with occupancy sensors that control lighting. Sports Complex was renovated and expanded in 2015. This building is equipped with occupancy sensors that control both lighting and HVAC equipment.

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:

The College has been systematically retrofitting and recommissioning buildings for the past 3 years and will continue to do so on a continuous basis. A major part of the retrofits is to add direct digital controls to HVAC systems.

A brief description of any energy metering and management systems employed by the institution:

All buildings are separately metered for natural gas, water and fuel oil. Over 95% of the campus' electricity usage is on one master electric meter. Since 2012, 20 electric meters have been installed and more will be installed over the next few years. Currently 80% of the College's electricity consumption is able to be measured at building level. The College is also in the process of implementing a campus wide energy management system (EMS). Currently 13 buildings are equipped with direct digital controls that are tied to the campus EMS. Each year 1 to 2 buildings are added to the centralized EMS.

A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

All appliances, kitchen equipment, copiers and printers, computers, and HVAC equipment replacements are 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:

All vending machines are equipped with LED lighting and internal timers that place them in standby mode over night.
