Various techniques can significantly reduce energy consumption. Passive methods are becoming popular; i.e. Proper building orientation to maximize passive solar potential and the positive impact of appropriate shading.
– Low E, Argon & Super Spacer
– smart window technologies
– increased thermal resistance in all insulation
– high furnace efficiency
– integrated furnace/hot water heating systems
– stationary fuel cell utilization
– heat recovery ventilators
– energy efficient lighting (i.e. Compact fluorescent and electronic ballasts)
– zoned heating/cooling systems and improved ductwork distribution
– programmable thermostats and smart technologies
EnerGuide for houses is an energy rating system designed to evaluate the efficiency of existing houses according to Natural Resources Canada guidelines. EnerGuide for houses uses software to analyze house data and produce an energy efficiency rating based on the home’s estimate annual energy consumption.
Homes are rated on a 1 – 1—scale. A 0 indicates significant air leakage, limited or no insulation and high energy consumption. A home rated near 100 is very well insulated, properly ventilated and requires no purchased energy (i.e. a solar house). Older homes typically rate in the 50-65 range, with R-2000 being above 80.
