A home in Ottawa has achieved Canada’s highest rating for energy efficiency in a residential renovation. The quarter-century home scored 90 on the federal government’s EnerGuide for Houses (EGH) rating, well above the 80 required for a new R-2000 house. Of all homes built in the 1980s that have upgraded their efficiency levels, the average EGH rating is 72.
The green home is owned by Bill Eggertson, head of the Canadian Association for Renewable Energies, who spent five years lowering the demand for electricity and space conditioning, while installing a range of technologies to supply low-carbon energy.
Notable additions include a geothermal heat pump, heat recovery ventilator, Energy Star metal roof and, most recently, tripled-glazed windows with Krypton gas to handle the expansive south-facing vista.
Eggertson has been involved with renewable energies since 1985, and worked for the national solar, wind and geothermal associations before launching the broad-based Canadian Association for Renewable Energies. He recently worked for the UK government on climate change diplomacy in Canada, was trained by Al Gore under The Climate Project initiative, and was appointed to the City of Ottawa’s former Environmental Advisory Committee in 2009.
