Another example: NOW House
• 60 Year Old Post-War Housing in Toronto, converted to near net zero energy.
2. Passive House
• The most advanced standard for energy efficiency new home construction in the world.
• The one I visited is so well insulated, it doesn’t require a furnace.
• Examples – see video about Hawkins house and pictures of Naugler house.
What is different about the construction of a Passive House?
• Highly insulated• Thicker walls• Meticulously sealed• Triple-glazed windows• Dual wall construction to eliminate thermal
bridging.• Solar gain through windows is the main heat
source (plus the appliances and people)• Must have a heat recovery ventilator for
ventilation.
