What would happen if you built the most energy-efficient new home available in the neighborhood, and put it up for sale right beside regular new homes? That’s what Natalie Leonard of Passive Design Solutions has done in Halifax, Nova Scotia, Canada. Her goal is to prove that a Passive House will sell in an ordinary new neighborhood.
Passive House is the most energy-efficient home design standard in the world. Drawing inspiration from Saskatchewan, Canada, and developed to science in Germany, Passive House has now come home to North America on a wave of desire to save energy and reduce greenhouse gas emissions. The basic principle of Passive House is - insulate, insulate, insulate! The extra money spent on insulation is saved by needing only tiny heating equipment and getting only tiny energy bills.
This lovely new home on Hadley Crescent, heated with one mini-split heat pump, will have a heating bill of less than $250 per year. Its neighbors will spend just over $1400 per year on heat alone. Add in the savings on air conditioning in the summer, super-efficient appliances like a heat pump hot water tank, and the Passive House is ahead on total energy savings by over $2,400 per year.
The catch? It cost about $15,000 extra to build. But you know what? The savings on energy (~$200/month) are greater than the extra cost on a mortgage (~$90/month). You save $110 a month to live in this Passive House! We can't say it any clearer. Oh, and there are three other benefits of this home you will appreciate:
