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


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

Per UMass Lowell's Guideline to Energy Conservation, the temperature guideline for offices, classrooms, residences, and teaching labs is as follows: occupied temperature of 77 ºF for cooling and 70 ºF and unoccupied temperature of 85 ºF for cooling and 55 ºF for heading +/- 2 ºF. These guidelines are prescribed by the Governor's Executive Oder #484 and limit heating to a maximum of 70 ºF and cooling to no lower than 77 ºF.

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

Per UMass Lowell's Electrical Standards (Section 26 00 00), interior lighting must incorporate best available energy efficient technology for lamps, luminaries and control equipment. Use of LED lighting is recommended for maintenance and energy efficiency. All task lighting should be LED.

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

Per UMass Lowell HVAC Standards (Section 23 00 00), separate zones shall be created for areas with solar exposure and interior spaces. Active controls such as CO2 and occupancy sensors shall be used for special spaces such as conference rooms and private offices that can sense space use and respond accordingly. Per UMass Lowell Electrical Standards (Section 26 00 00), enclosed space lighting controls shall include multiple switching and either occupant, daylight or light level sensors. Every luminaire shall be controlled by wall switch or occupancy sensor. Small closed spaces with glazing, provide multiple switching and photoelectric sensors. For small closed spaces without glazing, include multiple switching and occupancy sensors. Occupancy sensors shall be provided for assembly areas, offices, classrooms, toilet rooms, labs and conference rooms. Large open spaces shall be sub-divided into lighting zones and incorporate multiple switching. Classrooms with AV equipment and conference rooms/auditoriums shall have dimming capability. Exterior lighting shall be controlled by a photo sensor.

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:

Extensive retrofit programs are ongoing to replace lighting and HVAC equipment and control systems with newest technology high efficiency systems, e.g. Multi-Stack Turbo-Cor magnetic levitation bearing chillers; North Campus Steam Plant upgrade with new boilers, economizers, etc.

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

UMass Lowell installed more than 100 real-time, building-level energy meters on campus to track electricity, gas and steam usage and identify opportunities for increasing efficiency, especially during peak hours using energy intelligence software. The software allows UMass Lowell to prioritize projects more effectively, mitigate peak demand charges, achieve persistent savings, avoid maintenance costs, and measure and verify savings.

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

UMass Lowell's Accelerated Energy Program (AEP) Performance Contract is being kicked off in FY 15 as a campus wide energy program to save a total of 25% of all energy in buildings being affected by the scope (annual utility usage reductions of 483,000 therms, 5.75 MWh, and 2.5 Million gallons water).

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:
