Energy Retrofit, Air-Tight and High Performing Home Designed by Solares Architecture
This 2017 retrofit near downtown Guelph included a fully renovated main floor and an underpinned basement. Beyond that, two additions were removed from the rear of the property to allow for more light to enter the space. The building is heated through electric baseboards due to the extremely air-tight envelope, essentially the high levels of insulation meant the baseboards were hardly required. The concrete slab was R-20, the walls were R-35 and the roof R-60, this along with a tight building envelope helped to achieve a low air change rate per hour. Above all, the principles of air-tightness, high insulation levels, ventilation and superior quality windows were crucial for the success of this project.
Solares and Evolve were able to work together and produce one of Guelph’s most efficient homes. There were significant challenges but the results speak for themselves. Most noteworthy, by designing and following key details this building was able to produce the following results:

He writes the column titled the “Architourist” where he travels and selects particular buildings that are interesting for many reasons, in this case it was for this spectacular project.
