No. I think one of the areas that NRC excels in is a multidisciplinary approach. Often when we look at energy efficiency, we can realize collateral benefits. We also need to ensure we don't bring along unintended consequences. Increased air tightness means fewer air exchanges, which can mean reduced air quality.
Where NRC is engaging specifically in the north in one collaborative activity with our colleagues at NRCan is in looking at the air quality inside highly energy-efficient homes and looking at ERVs and HRVs—energy recovery ventilators and heat recovery ventilators. We're making sure that the technologies that were developed for the south are applicable in the north and that there's a northern solution that works for the northern people, given their unique set of cultures and needs.
