TCAAP Energy Integration Resiliency Framework Policy White Paper – Exhibit I - Definitions 64 Exhibit I – Definitions The following definitions are provided for those unfamiliar with energy system terminology: Air Handling Unit (AHU) – A central unit consisting of a blower, heating and cooling elements, filter racks or chamber, dampers, humidifier, and other central equipment in direct contact with the airflow. This does not include the ductwork through the building. Active solar – As an energy source, energy from the sun collected and stored using mechanical pumps or fans to circulate heat-laden fluids or air between solar collectors and a building. Alternative-rate Energy Efficiency program assistance – An Energy Efficiency (demand-side management) program assistance that offers special rate structures or discounts on the consumer's monthly electric bill in exchange for participation in Energy Efficiency programs aimed at cutting peak demands or changing load shape. These rates are intended to reduce consumer bills and shift hours of operation of equipment from on-peak to off-peak periods through the application of time-differentiated rates. For example, utilities often pay consumers several dollars a month (refund on their monthly electric bill) for participation in a load control program. Large commercial and industrial customers sometimes obtain interruptible rates, which provide a discount in return for the consumer's agreement to cut electric loads upon request from the utility (usually during critical periods, such as summer afternoons when the system demand approaches the utility's generating capability). Arden Hills Army Training Site (AHATS) – A military training area of Minnesota National Guard and the Minnesota Department of Military Affairs that is directly adjacent to the Rice Creek Commons Project to the east. ASHRAE Bin temperature data – Temperature frequency in 5 F intervals available from American Society of Heating, Refrigerating and Air-Conditioning Engineers. Boiler – A device for generating steam for power, processing, or heating purposes; or hot water for heating purposes or hot water supply. Heat from an external combustion source is transmitted to a fluid contained within the tubes found in the boiler shell. This fluid is delivered to an end-use at a desired pressure, temperature, and quality. British Thermal Unit (Btu) – The amount of heat required to raise the temperature of one pound of water 1 degree Fahrenheit. The Btu is a small amount of heat equivalent to the heat released by a burning matchstick. For district heating systems, heat is often measured in million Btus (MMBtu) which is equivalent to one million Btu’s. Building Commissioning - a building performance quality assurance process that begins during design and continues through construction, occupancy, and operations. Commissioning ensures that the new building operates initially as intended by design and that building staff are prepared to operate and maintain its systems and equipment.
