A home in Canadaâs capital has achieved the highest rating for energy efficiency in a residential renovation, scoring 90 on the federal EnerGuide for Houses rating.
Online PR News – 31-January-2013 – OTTAWA, Ontario – A home in Ottawa has achieved Canadaâs highest rating for energy efficiency in a residential renovation.
The quarter-century home scored 90 on the federal governmentâs 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.
âAll our energy technologies are commercially available,â says Eggertson, who managed the design and installation of most components. âWe just went beyond the normal, to show that older homes can easily meet and surpass the efficiency levels for new construction.â
Eggertsonâs home was the first in eastern Ontario to install a 10 kilowatt solar rooftop array under the microFIT program. He is working with his solar installer to develop a âblack boxâ that will allow the on-site generation to be used during a grid failure, something which the province currently does not allow.
âThe toughest part of the renovation was making concessions to my wife to install granite countertops,â he jokes. âWe complied with LEED (Leadership in Energy & Environmental Design) guidelines, and part of our goal was to show that the most energy-efficient renovation in Canada can also be a beautiful home.â
âOur energy efficiency score of 90 lays down the gauntlet, not only for new homes but for older ones too,â he says. âWeâre saving a lot of money, reducing our carbon footprint to zero, increasing our homeâs equity, and boosting the comfort level significantly for our family.â
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 (we c.a.r.e.). 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 Ottawaâs former Environmental Advisory Committee in 2009.
