Refining Your HRV / ERV Choices

New year, new resolutions, new builds. If new HRV/ERV systems is on the top of your list, then this recap article by Gord Cooke, originally published Better Builder Article, Winter 2016, is a must read.

Please don’t blame me, but the new 2017 Ontario SB-12 Supplementary Standard for Energy Efficiency requires all Part 9 dwellings to meet the Principal Ventilation requirements with an HRV or ERV. Certainly I have been an advocate for proper balanced ventilation for over 30 years, but I think most readers will know that this specific new requirement is a natural progression. The requirement for mechanical ventilation first appeared in 1990. With recognition that ventilation without heat recovery can easily represent 15-20% of the annual energy loss of a home, it stands to reason there needs to be an energy efficiency requirement on ventilation in the same way as other house components such as furnaces, water heaters and even windows and walls are required to meet minimum energy efficiency levels.read more
