Welcome to the 4E podcast on High Performance Building in Cold Climates. At 4 Elements, we’ve been involved in high performance building since 2008.  At that time, few people stopped to even consider the concept of high performance building in a residential context in a Canadian climate.  The few builders and individuals who did were very much on the fringes of the residential construction industry.  A little over a decade later, things have started to change but still, few people really understand the challenges and constraints that come with building high performance buildings in cold climates.Come join us in Episode 1 and learn about in the importance of air quality in our homes starting with our minimum standards set by code and look ahead to today's best high performance homes.   

Part 2 of our deep dive in healthy indoor air quality and ventilation continues!  History and background of Ventilation in homes, why fresh air supply in important and how we need to deal  with contamination.  Gaining an understanding of filtration and control strategies. Special Guest, Dr. Nielsen, joins us to talk about a medical doctor's perspective on indoor air quality and his goals when building his own LEED Platinum home.
