In terms of energy efficiency, the original plan was to upgrade the windows and the insulation in the above ground framing. However, due to the fact that the perimeter drain of the home was failing and had to be dug up and replaced, we got the opportunity to foam insulate the entire foundation from the exterior so as to achieve superior thermal resistance. Then, the decision was made to add and exterior layer of 2” rigid Rockwool comfortboard insulation to the entire exterior so as to stop any thermal transfer through the wall assembly. By combining the upgrades of the windows, the building envelope and the mechanicals we were able to achieve and energy efficiency equivalent to a newly built Step Code 3 house.
- The client wanted to do a renovation on their 1970’s Whistler home.
- The aim was to enhance the original interior layout of the home to make it more useful for their stage in life, as well as upgrading the mechanical and electrical systems, kitchen, bathrooms and the overall energy efficiency.
- At the same time, the client wished to maintain the original look and feel of the home. This required us to re-use a large amount of the original cedar paneling (green retrofit) of the interior and the original siding on the exterior.
