NAIT Plumber Period 4 Theory Practice Test

The EnerGuide rating system evaluates the energy efficiency of homes. A rating typically in the range of 65-72 often describes a new construction home because new builds are generally designed to comply with current energy efficiency standards and codes, which have progressively tightened over the years.

Homes rated in this range usually incorporate energy-efficient windows, insulation, heating systems, and sometimes renewable energy sources. This standard reflects the improvements in construction practices and materials that have become common in the industry, leading to better overall energy performance compared to older homes.

Higher ratings, such as 75-80 or 80-85, are usually indicative of homes that feature advanced energy-saving technologies and practices beyond the standard new builds, which are not always implemented in every new construction project.
