One of the best first approaches to reducing energy use is through optimizing the building envelope to minimize heating and cooling (HVAC) loads – this can be accomplished through increased insulation, air tightness, and the quality of the windows.
The ERC is highly insulated in order to keep heating and cooling loads to a minimum. A minimum of R40 insulation is used on the roof and R30 in all of the walls – both assemblies of which exceed the insulation requirements of Canada’s Model National Energy Code for Building.
By increasing the insulation in the building, resultant demand on mechanical systems is reduced, this leads to greater overall energy savings for the building. The Earth Rangers Centre is nearly 90% more efficient than other “normally constructed” buildings of its size.
