The first home in British Columbia to meet international Passive House Standards will also double as affordable housing for Whistler families, proving that building energy efficient homes can be affordable.
The passive solar design and orientation of homes is anything but new. Solar heat collection is a technique that has been used in home construction for thousands of years. What is relatively new is the rating system developed to certify them.
The Passive House or PassivHaus standard originated in Germany in the late 1980’s and currently boasts over 30,000 certified buildings around the world, with 16,000 in Germany alone.
In 2010, a passive house from Austria was assembled in Whistler for the Olympic Games, however, the Rainbow Duplex designed by Marken Projects marks the first Passive House to be solely constructed in B.C. using primarily local products.
Using up to 90% less energy for heating, cooling and building operation than a standard house, the Rainbow Duplex was assembled in 4 ½ days using a prefabricated panelized system manufactured by BC Passive House.
A successful passive solar home is designed to absorb as much of the sun’s heat as possible in the winter months, without over heating in summer months. Solar hot water collection, a subsoil heat exchanger and cross-laminated timber decking are a few of the extensive sustainable building features incorporated into the prefabricated design, which also meet requirements for Whistler’s Price Restricted House Initiative.
“One of the major hesitations associated with ultra-low energy buildings is the construction costs,” said Alex Maurer, director of Marken Projects and a leading expert in Passive House Design and Planning. “We wanted to show that building sustainably isn’t only for the affluent. With a little innovation homes can be both energy efficient and affordable.”
“We’re very excited to see the continued growth of PassivHaus construction in Whistler,” said Mayor Wilhelm-Morden. “Affordability and energy efficiency are both core to our long-term sustainability strategy in Whistler.”
The Rainbow Duplex Passive House will be open for public tours on both Saturday April, 14th and 28th from noon to 7 pm. For more information on the project, visit http://www.markendc.com/ and http://www.whistlerpassivehouse.com.
