❖ STERLING HOMES
Turns out, the home will be a bungalow, a logical choice for a net-zero design. “It will be an 1,850-square-foot bungalow,” says Courtney Sims, Qualico’s marketing and digital sales manager for Broadview Homes and Sterling Homes. “We chose a popular model for the community with the goal of determining building practices and costing for building this model as a net-zero home. By doing that, we thought we’d be able to offer more net-zero
builds to more customers.” Not surprisingly, there’s a lot more planning required to build a net-zero home. After all, it is going to be anything but an ordinary home. That being the case, building specifications are going to be much higher than that of a typical bungalow. One of the biggest differences between the new show home at 9 Morgan and other standard builds is going to be the home’s
overall insulation values, which are going to far exceed normal standards. “Downstairs in the lower level, added insulation will create a warmer feeling space,” says Dale Verville, production manager for Broadview Homes and Sterling Homes, noting basement insulation will be R14 mineral wool with three-inch Halo GPS (graphite polystyrene) to increase the total frost wall R value to R29.

1 Roof There will be two dozen 500-watt solar panels on the roof modelled to collect 16,140 kilowatt hours of energy per year.
2 Amenities The home will have an electric air handler and a hybrid hot water tank to provide hot water, while a cold climate heat pump replaces the need for an air conditioning unit.
