DESIGNED TO PrODuCE ITS OwN ENErGy The Parkland NetZero project is a certified LEED Platinum, single-family home in Parkland County just south of Spruce Grove, Alberta. The two storey, 4,025 square foot home acomodates a couple and their three children with a secondary suite. By Peter Amerongen

ThE PrOjECT AIMED TO AChIEvE fOur kEy OBjECTIvES Net Zero Energy: the project was designed to produce all of its own energy for heating, hot water, lighting and appliances, on site, over the course of a year. the designers were guided by the passive house idea that reducing building envelope losses and using passive solar strategies could be partially paid for by savings from the consequently smaller and simpler mechanical systems. The aggressive conservation measures: of the passive house approach were also the most effective way to reduce the size of the photovoltaic array required to meet the annual heating needs. the end result is a house that is predicted to use only 23% of the energy required for a similar home with conventional construction. heating and domestic hot water loads loads have been reduced to the point where it is more economical for them to be provided by a grid tied photovoltaic system. Reduced Environmental Footprint: materials and strategy decisions were vetted against a comprehensive matrix of environmental considerations: embodied energy, environmental impacts in manufacture, effect on indoor air quality, proximity of manufacture, durability, recycled content, and recyclability. Demonstration: the owners felt a responsibility to demonstrate that it was possible to make these deep reductions without sacrificing beauty and comfort. they have hosted numerous public open houses, and guided tours. On-going monitoring will tell whether it reaches the net zero energy goal.
