A home of any size or design can be built as an R-2000 Home.
R-2000 is a performance standard. As such there is no typical way of putting together an R-2000 Home. Homes can vary from what appears to be a fairly conventional design to double wall or structural insulated panel high performance systems.
In Manitoba, a house heated by natural gas in the southern portion of the province might typically meet the R-2000 performance target with the following components:
- R-50 attic insulation with raised heel trusses.
- 2 x 6 exterior wall construction with R-20 insulation.
- R-20 or R-24 basement wall insulation.
- Triple paned, lowE, argon filled, window glazing with insulated spacer bars.
- Perimeter rigid foundation insulation over drain tiles.
- High efficiency sealed combustion gas furnace.
- High efficiency heat recovery ventilator.
- Electric or induced draft gas hot water tank.
- Air tight building envelope.
These upgrade costs typically add between 2% to 4% onto the cost of your home depending on your location and local market. Since each of the upgrade items has the effect of lowering your heating bills (R-2000 Homes consume 20% – 30% less energy than equal conventional homes) the upgrade costs are paid off through energy savings.
Because the R-2000 standard takes into account all factors such as local weather conditions and heating fuel used, the design requirements for R-2000 homes vary for each individual house.
