A brief description of when and why the building energy consumption baseline was adopted:
The baseline was adopted because it is the first year that the data was obtained.
A brief description of any building temperature standards employed by the institution:
University Temperature Guidelines – As per the UAA Energy Policy
UAA follows ASHRAE Standard 90.1 comfort standard guidance that has a range
of 68 to 81° F. Generally speaking classroom and office buildings “hibernate” after 11 p.m., when heating and ventilation equipment is set lower. Buildings start to come back online around 6:30 a.m. so that they are at their preferred temperature by 8 a.m. Building starts are staggered based on the type and time of building occupancy and nature of equipment. Most buildings are set to hibernation mode during the weekends. If we anticipate a prolonged period of To maintain reasonable comfort and lower energy expenditures, summer building temperature comfort ranges(cooling) are to be between 70 and 78° F, and winter settings (heating) are to be between 68 and 74° F.sustained cold (below 10° F), the buildings will be maintained at normal day time temperature ranges 24/7 until the weather improves.
A brief description of any light emitting diode (LED) lighting employed by the institution:
Along with photocell sensors, UAA also uses timers. After 11 pm, half of the campus
lights are scheduled to turn off, and when more lighting is needed for snowplowing, the contractors are able to push one button to turn additional lamps on for a limited time.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
UAA uses motion sensors in most of the newer buildings and these buildings can also be programmed to a non-occupancy mode when applicable.
A brief description of any passive solar heating employed by the institution:
Passive Solar Heating and Daylighting are hit and miss buildings in Alaska, but we incorporate as much as possible while maintaining as high an insulative value (R-value) as possible to retain heat. Loss of heat thru south-facing windows of R-10 (at best) in 0F to -20F temps and low light of DEC, JAN, and FEB may negate any gains of 20-hour lighted days in MAY, JUN, JUL. Building orientation and siting is taken into consideration for potential passive solar application for every new building we construct (master planning effort).
A brief description of any ground-source heat pumps employed by the institution:
We do not have any ground-source heat pump at UAA
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:
Recommissioning – For our most recent new construction, we have instituted a procedure where we recommission a building at 18-24 months from date Certificate of Occupancy to reassess the actual building performance compared to the design and original commissioning data, and make adjustments/corrections/repairs accordingly.
A brief description of any energy metering and management systems employed by the institution:
UAA employs the use of Energy Monitoring & Controlling (EMC), a Siemens product, for tracking and analyzing energy utilities, i.e water, gas and electricity.
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
Energy Audit – In 2011, UAA FP&C did contract a company, Ameresco, to perform an energy audit with a grant from AHFC (Alaska Housing Finance Corp). We have taken the results of that report and invested in less costly repairs or upgrades that had immediate or short term paybacks (like upgrading parking lot lighting from halogens to LED lights) and saved the more expensive and disruptive projects for departmental remodeling or whole building capital renovation projects, which cover things like window/door replacements, high-efficiency boiler upgrades, and “smart” energy control & monitoring systems.
A brief description of any energy-efficient landscape design initiatives employed by the institution:
The landscaping team at UAA integrates environmental responsibility into their daily operations, and has been recognized by TREErific, and the American Society of Landscape Architects Alaska Chapter for its sustainable practices. UAA has created a campus tree tour, a geological rock garden, and an herb garden to promote both student
and public engagement. The landscaping team uses five sustainable principles throughout campus as it composts, reuses materials,
reduces water consumption, and protects and restores natural
habitats. All of this helps to keep plants healthy naturally and avoids the need for pesticides
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
In 2006, after confirming energy savings, UAA wrote into its vending machine supplier contract that Vending Misers must be installed on all UAA vending machines, with the exception of food and hot beverages. All vending machines with the exception of food and hot beverages utilize vending misers. As of now theUniversity of Alaska Anchorage has 74 Vending Misers installed on vending machine throughout the campus.
A brief description of other energy conservation and efficiency initiatives employed by the institution:
Most of the time older buildings are remodeled and during that remodeling, more efficient equipment are installed.
