The RMA Administration Building was built on unused Alberta Transportation land left over from the creation of Highway 2, between the Edmonton International Airport and the main rail line. The 1,252 m2 building was constructed using a highly-insulated wood frame wall and roof system and incorporates the following energy efficient technologies:
Lighting – Motion-sensor, high-efficiency T8 fluorescent lights were installed throughout the building.
Water Systems – The building uses dual-flush toilets, waterless urinals, and faucets with ultra-low flow restrictors and occupancy-activated shutoff controls.
Geothermal Heating and Cooling – A geothermal heating system uses 60 holes located in the field north of the building to an approximate depth of 200 feet. The system provides both the building’s heating and cooling needs with a loop temperature between 55 and 60 degrees Fahrenheit. Slab heating with embedded pipes provides even heat throughout the floor area, allowing for complete fan shutdown when the building is unoccupied.
HVAC – Ventilation is supplied by heat-recovery ventilators, which are rated to extract 75% of the thermal energy from stale air exhausted from the building.
Building Envelope – The building’s stucco is made from recycled tire crumb, increasing the insulation value of the exterior. Walls and roof are made from a highly insulated wood frame system.
Solar PV – Thirty-three solar panels were installed in 2007. The panels produce more than 7,000 kilowatt hours of power a – slightly more than the amount of energy needed to power a large home.
