Mark Ashby Architecture offers design service for Passive House design and certification. This state-of-the-art European sets the bar for energy performance in residential and commercial construction. A Passive House is an energy-efficient home that saves as much as 90% of the energy used to heat a conventional home. This is achieved with efficient design, superior insulation and high-quality, triple-glazed windows. Passive Houses are: Comfortable, Quiet, Affordable, Healthy, and Resilient.
Passive Houses are comfortable
Superior insulation and air-tight construction ensures that Passive Houses are comfortable, warm and draft-free all year round. Careful design admits the sun’s heat in the winter months and shades windows in the summer months to keep the Passive House warm in winter and cool in summer. No more cold floors or uncomfortable rooms! Thick insulation and high-quality windows keep all surfaces warm to touch and prevents uncomfortable temperature swings, day and night, all year long.
Passive Houses are quiet
Thick walls and high-quality, triple-glazed windows block noise at the door, allowing you to enjoy your home in quiet comfort.
Passive Houses are affordable
Designing and constructing a Passive House can cost as little as 10% more than a conventionally constructed custom single-family home.
(Economic study of Canadian Passive House projects in British Columbia indicate a construction cost premium of less than 10% over a base construction budget of $200/sq.ft.)
Passive Houses dramatically reduce heating costs.
In many cases monthly energy savings negate the monthly cost for additional construction financing. With energy prices on the rise, the benefit of energy efficient design will increase in the future.
Passive Houses are healthy and resilient
An efficient ventilation system using heat-recovery technology provides filtered, fresh air directly to bedrooms and living spaces. Passive Houses are virtually dust-free. Passive Houses provide peace of mind. In the event of a prolonged black-out, a Passive House will lose heat much more slowly than a conventional home and will stabilize at 16-17°C due to solar heat gains, even in the winter. Mark Ashby Architecture is the architect for the first house designed to the Passive House standard on Salt Spring Island.
