A brief description of when and why the building energy consumption baseline was adopted:
2006 was chosen as the baseline year as it is the first year for which UNH has meter data.
A brief description of any building temperature standards employed by the institution:
All core campus buildings are tied to our energy management system, which increases and decreases temperatures based on occupancy and time schedules. Typical spaces are heated from 7am-10pm as a maximum M-F and off on weekends. We also use sensors to turn off space heating in some areas. For classrooms, we use the schedule from the registrar’s office to also shut down spaces when unused. If someone is in the space when the system is off, they have an override button that will give them 2 hours of heat. For areas not on the core campus, we employ programmable thermostats which mimic the normal hours for the space.
A brief description of any light emitting diode (LED) lighting employed by the institution:
UNH does use LED lighting. More information can be found in the University of New Hampshire Construction and Renovation Standards - Section 16510 Interior Luminaries
Choice of fixtures are made with the following considerations:
a. Energy efficiency and sound rating
b. Quality of lighting
c. Ease of installation and installation flexibility
d. Ease of maintenance
e. Suitability for the specific application
f. Replacement parts availability
g. Consideration of potential abuse
UNH has also moved away from exterior metal halide fixtures and has identified LED replacements as the new exterior fixture of choice. We are already using them in walkway, street, and building exterior fixtures.

A brief description of any occupancy and/or vacancy sensors employed by the institution:
Light sensors are used in over 75% of campus buildings ranging from occupancy sensors in office, bathrooms, classrooms, etc to daylighting controls that reduce light output based on incoming natural light through windows. Our occupancy standard is Wattstopper brand sensors and other systems have been utilized to control corridors, daylighting, and A/V controls such as Lutron and Square D. More information is available in Section 16510 and Section 16530 of Design Standards.
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:
As mentioned above, EcoLine is the primary fuel source for the on-campus COGEN plant. The COGEN plant retains waste heat normally lost during the production of electricity and instead uses this energy to heat buildings, in turn reducing sulfur dioxide and nitrous oxide emissions. The installation of the COGEN plant resulted in an estimated reduction in greenhouse gas emissions of 21% in Academic Year (AY) 2006 compared to AY 2005.
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:
UNH utilizes an energy management system featuring Andover controls (TAC) that allows the UNH energy office to monitor and adjust building energy systems based on automatic occupancy sensors, classroom scheduling, and other devices that trigger the equipment to turn off or ramp down in energy use to minimize consumption.
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:
UH has begun using EnergyMisers in vending machines on campus. When equipped with the VendingMiser®, refrigerated beverage vending machines use less energy and are comparable in daily energy performance to new ENERGY STAR qualified machines. Maintenance savings is generated through reduced running time of vendor components, estimated at $40 - $80 per year, per machine. Energy consumption is reduced an average of 46% -- typically $150 per machine annually.
