DESIGNING & BUILDING AN ENERGY EFFICIENT HOUSE
Construct a tight envelope
Insulate with R-values 20, 40, and 60. R-value is a measure of an insulation’s ability to reduce the rate of heat flow.
Efficiency Tip: use R20 for basements and under slab, R40 in walls, R60 in attic/roof.
OTHER KEY ENERGY FACTORS ?!
GLAZING - The area (ft2) and performance of glass windows and doors
PSI VALUE - The measure of heat loss along a junction, i.e. floor & external wall
YEARLY ENERGY DEMAND - All the energy needed by the building, assessed for HEATING & COOLING, HOT-WATER AND PLUG-LOAD ENERGY
PLUG LOAD ENERGY CONSUMPTION - Lights, appliances, anything plugged into the wall
PEAK POWER LOAD - Assessed for worst-case heating & cooling needs in winter and summer months
