On March 9th, 2016, Canada’s net zero home builders gathered in Ottawa, Ontario to celebrate the wrap up of the NRCan OC ecoEII Net Zero Energy Housing Project.

Owens Corning Canada kindly recognized buildABILITY and other partners on the project for their hard work and contribution to the project in the last 4 years.

Michael Lio, President of buildABILITY, spoke about net zero and what the future will hold on this emerging technology:

“This is an emerging technology. As electricity prices go up (and they are and they will) and as solar panel prices go down (and they have and they will) businesses and the public will increasingly adopt these measures,” said Michael Lio of buildABILITY Corporation, a renowned building scientist and manager of the project. “This initiative helped to debug the adoption process so in future, these measures can be adopted seamlessly. To use an analogy: we have built a road through uncharted territory so that others can drive through effortlessly.”

Net zero project is building industry milestone

Canadian initiative sets out to prove energy efficiency is consumer-friendly and accessible

A calm, suburban neighbourhood in the south end of Guelph, Ontario, buzzes as people from various building organizations gather at 197 Goodwin Drive. They’re all standing around a new home that blends well into the Westminster Woods community aesthetic, but was built with a much different intention as the 33 solar photovoltaic (PV) panels on the back roof might indicate.

Unlike other net zero energy (NZE) homes that have been constructed across the country, this one, the first of 25 to be completed as part of a national demonstration project, uses consumer-friendly technology and products geared to the mainstream public.

“This shows a net zero home is not only possible, but also possible on the consumer scale where it can be available to everybody,” Guelph Mayor Cam Guthrie said before a ribbon cutting ceremony. “The home doesn’t just demonstrate new and exciting technologies; it changes the way homes are actually built.”

Rather than viewing the project as a one-off, the builder, Reid’s Heritage Homes, used its standard construction plans in order to replicate the build in a production setting, as well as complete a home others can duplicate.

Reid Heritage Homes was selected to be part of the ecoENERGY Initiative (ecoEII) to build a total of five homes in Guelph. Other building companies—Minto, Mattamy Homes, Provident and Construction Voyer—will each build five NZE residences to be located in Ottawa, Alberta, Nova Scotia and Quebec, respectively. Each builder is working with a technical consultant. In this case, Reid’s Heritage Homes has been working alongside Building Knowledge. Upon overall project completion in 2016, the amount of NZE homes in Canada is expected to double.

Andy Goyda, Canadian builder lead and marketing development manager for Owens Corning Canada, a leader in the project, was also on hand to promote the technologies that make the net zero home healthier, affordable and comfortable. One key feature lies beneath the façade, in the form of the Owens Corning CodeBord air barrier system that helps achieve high levels of air tightness to meet net zero performance standards.

“Net zero starts with the envelope,” said Goyda. “If it isn’t super-insulated, we don’t go anywhere; if it is, everything falls into place.”

This “everything” extends to the installation of high-efficiency water heaters, air source heat pumps, triple-pane, low-e glass windows and market-ready renewables like solar PV and electrical storage capacity.

As for the air barrier system, which insulates the exterior of the building preventing thermal bridging from occurring and increasing wall insulation to R-38, a consequential reduction in condensation adds for more comfort and efficiency.

All of these efficient measures will be closely examined. Jennifer Weatherston, director of innovation for Reid’s Heritage Homes, says the home will be monitored for a two-year period as data is collected and analyzed. She also intends to observe how the technology influences owners.

“Do you take the energy device and throw it in the drawer after six months or do you keep learning and moving forward, changing behaviour?” Weatherston questions. “It will be interesting to see how people live in these homes.”

And with the first build set for listing on September 19, the homebuilders will also get a better feel for how many consumers are willing to pay a little more than the average home.

“Guelph is a greener area and more receptive to this type of thing and the location is ideal,” added Weatherston. “But, at the end of the day, what is going to sell these homes is the innovation, home comfort, the improved air quality and better design with the insulation.”

The project has come a long way since 2013 when the Natural Resources Canada first issued an announcement that it had $262 million to promote research and development in demo projects to improve energy efficiency across Canada. BuildABILITY, project manager and lead consultant for the ecoEII project, worked with Owens Corning Canada to develop a proposal that would take net zero to an affordable community production housing platform. And, Voila.

The remaining 24 homes will be complete by the end of 2016, while the initiative aims to leave an everlasting impression on the state of NZE. That’s not only in the residential sector, but other sectors as well.

Candice Luck, director of strategy and programs for buildABILITY, uses the analogy of “helping to build a road through uncharted land so that others can drive through effortlessly.”

“As electricity prices go up (and they are and they will) and as PV prices go down (and they have and they will) businesses and the public will increasingly adopt these measures,” adds Luck. “Our project promises to debug the adoption process so future measures can be adopted seamlessly.”

Michael Lio, President, speaks to Fine Home Building about the Net Zero Project buildABILITY has been working on with Owens Corning Canada.

Canada Launches a Net-Zero Project

By Scott Gibson Aug 03, 2015

In Canada, private and public interests are working on a common problem: How to build net-zero-energy housing that average homebuyers can afford.

Asked by officials in the government’s ecoEnergy Innovation Initiative for some new ideas on how to encourage energy-efficient building, a company called buildABILITY Corp. put together a program in which five separate builders were invited to tackle the net-zero problem in whatever way they chose. As a result, single-family homes and condominiums are going up in five cities in four provinces as builders work with their own consultants to produce affordable net-zero-energy houses in their respective markets.

Natural Resources Canada chipped in $2 million from the national $278 million ecoEnergy program. Owens Corning Canada provided insulation products for free, and builders themselves came up with in-kind contributions that equaled the government’s ante, says buildABILITY president Michael Lio. The net-zero houses, all of which must be completed by next March, will be sold privately after the government double-checks to make sure they really will produce as much energy as they use.

The larger goal of the Owens Corning Net Zero Housing Community Project is to help production builders figure out how net-zero building practices can become part of their regular repertoires.

“We’ve been talking about it for a long time,” Lio said recently. “There have been lots of net-zero buildings that have been constructed both in the U.S. and in Canada, but there haven’t been many activities that focused on production builders, and even fewer on affordability. So at the heart of this project is to work with large production tract builders to bring them to net-zero so it’s more affordable for their customers, to simplify it and drop it into their assembly-line processes.”

Builders find common ground

Builders are working independently. There’s no central agency directing their work, and there’s no common script they have to follow. Even so, Lio says, builders have settled on very similar approaches. “The technologies are off the shelf,” he says, “very accessible.”

Some of the common building characteristics:

• Grid-tied photovoltaic systems for on-site renewable energy, with arrays rated at about 10kw.
• Exterior walls with R-values between 38 and 44. Wood-framed walls have cavity insulation of fiberglass batts and an exterior wrap of extruded polystyrene rigid insulation.
• Airtightness, measured with a blower door, of 1.5 air changes per hour, or lower, at a pressure difference of 50 pascals.
• Triple-paned windows.
• Although some builders have chosen small-output furnaces, many others are using cold-climate air-source heat pumps.
• Heat-pump water heaters.
• Interior polyethylene vapor barriers.
• Attics insulated with batts or blown in fiberglass to a range of R-50 to R-70.

Lio says the units have fairly small heating loads (most of the projects are located in Climate Zone 6). Half the 10kw output of the PV arrays are on average used for base electric loads, Lio says, with one quarter devoted to space heating and the balance to domestic hot water.

Builders will sell the houses at market rates, Lio says, but because of program restraints they won’t be allowed to make a profit on building components that contribute to net-zero operation.

Construction costs are similar

Projects are underway in Laval, Quebec; the Ottawa suburb of Kanata; Calgary, Alberta; Halifax, Nova Scotia; and Guelph, Ontario, just to the west of Toronto. Lio says land prices vary widely, but construction costs are similar across the country. These houses range from one-bedroom condos to single-family houses of about 2000 sq. ft. in the $500,000 price range.

The incremental cost of getting to net-zero on a single-family home is looking like $60,000 to $80,000, Lio says, a 12% to 16% premium over the cost of a conventional house. Lio says it’s too soon to know whether Canadian homebuyers will be willing to pay it.

“I think that as a full-on market initiative, we’re really early,” Lio says. “I suspect there will be some homebuyers who have an eye on innovation, who want to be the very first to adopt a particular technology and will certainly buy these houses.

“We’ve seen dramatic shifts in the pricing on some of these systems, particularly on-site generation, and as some of these systems become even more affordable and builders start to adopt the technology in volume, then it would be appropriate to have a conversation about what the market would bear. Right now, it’s conjecture. Prices are high, numbers are low, and it’s really unfair to talk about would someone be willing to dish out $80,000.”

Building on a Canadian tradition

Canada has a long history of high-performance building and introduced its R-2000 program in the early 1980s. As Lio points out, standards typically become more demanding as time passes.

“The R-2000 is in many regards the springboard for these net-zero houses,” he says. “R-2000 is an energy standard, but it doesn’t include on-site generation. These net-zero houses not only demonstrate the new type of energy efficiency that’s embedded in the R-2000 standard but it takes that next leap and embeds on no-site renewables.

“That’s the real difference,” he adds. “It’s a continuum. We’ve been at it for a long time and we’ve made lot of mistakes along the way, but it’s pretty obvious that there’s this continuum and these programs that are voluntary eventually become the stuff of code minimums.”
