The idea of a Net Zero Energy (NZE) home is that it employs enhanced energy efficiency design strategies to cost effectively reduce energy needs, while meeting those needs with renewable energy technologies, with the result that the building consumes equal to or less energy than it produces on an annual basis.
The Net Zero Energy community project attempted to assess and resolve the challenges in relation to, among other things, site planning, construction, equipment, grid connections, cost, trade capability, warranty, reliability, sales, marketing, and homebuyer information/education.
The project successfully engaged production builders and completed 26 net zero energy or net zero energy ready homes. Team members continue to be involved in the net zero community and volunteer their time to move net zero forward as the country considers a near net zero or carbon neutral future.
This project demonstrated that NZEH is technically feasible for a production builder. The next step is to continue to disseminate this knowledge and encourage other influential production builders to build NZEH communities of their own. More field experience and data will help regulators move this target forward.

Michael Lio was recently interviewed by the Globe and Mail for his insights on net-zero. Below is a clip of the article containing Michael’s observations.
Can net-zero net the average homebuyer?

…
Millennials aren’t buying single-detached houses, yet, she says, but when they do, net-zero will be an expectation, not an upgrade. These buyers “tend to expect [net-zero] to be a feature within the home,” Weatherston says, based on the company’s experience selling town homes to millennial buyers. “They expect it to be standard.”
Weatherston says the market may be forced to respond even before the codes make them.
But for Michael Lio, a leader with the for-profit BuildAbility Corp., in Ontario, which works to create change in the housing industry, the key is electricity and energy prices.
Lio uses Ontario as an example of where net-zero can and can’t make sense to the average consumer. “In Ontario, for instance, given the high price of electricity, if you have a house that’s disconnected from natural gas lines and you’re currently heating with electricity or you choose not to use oil, then it makes a whole lot of sense to go that extra little bit and go to net-zero,” Lio says.
But, thanks to the cheap price of natural gas, “We are absolutely not at the tipping point of moving off it,” he adds.

TORONTO, SEPTEMBER 26, 2016—buildABILITY Corporation is proud to announce that our Director of Strategy & Programs, Ms. Candice Luck, is the recipient of Canada’s 2017 Clean50 award for her efforts in net zero energy housing innovation and adoption. She is one of 50 honourees in Canada to receive this recognition for 2017.
At the young age of 30, Candice is the project leader on an over $4 million initiative that doubled the number of net zero energy homes built in Canada—homes that, over the course of the year, generate as much energy as the occupants consume. Her pivotal role in unifying a team of production builders, regional consultants, and product manufacturers made the construction of 26 net zero homes in five communities across Canada a reality. The project successfully demonstrated to homebuilders the feasibility of building net zero and paved the way for widespread acceptance and industry adoption of net zero energy housing. With a focus on clean energy and green building in the recent Canadian federal budget, the project has given builders across Canada the opportunity to witness and learn about net zero in their own communities.

The Globe and Mail has featured us in an article for our participation in the Net Zero Energy Homes Project.
Net Zero Energy is an aspirational goal and there’s a lot more work to be done. Join us on our next adventure to make Net Zero Energy a reality!
Housing consulting group pursues a mass-market net-zero home
John Bentley Mays
Special to The Globe and Mail

Among the ideas about housing afloat in official Ottawa these days, few are more potentially significant over the long haul than the dream of the net zero energy (NZE) home. That’s a house, affordable and constructed for Canadian winters, that produces as much energy as it consumes over the course of a year. Theoretically, this means the homeowner might pay net nothing annually for heat, cool air and light – while usefully taking a load off the country’s power grid.
For its part, the federal government has been encouraging the translation of this dream into reality. But Canada’s suppliers of mass-market houses, mindful of market whims and the bottom line, have so far proven reluctant to invest in super-efficient residential buildings.
Enter, about four years ago, buildABILITY Corporation (bC), a for-profit consulting group whose principal client is the housing industry. The company, in co-operation with the federal ministry of natural resources and insulation and roofing products manufacturer Owens Corning Canada, had a plan for showing the industry, once and for all, that mass-produced NZE houses are feasible and desirable – and they aimed to get the industry itself to do the heavy lifting for their experiment.
For their first net-zero home as part of the Eco-Energy program, Reid’s Heritage Homes adapted one of their most popular home designs by adding a covered porch so they could accommodate 8 kilowatts of solar PV. (David Dodge / buildABILITY Corporation)
Backed by some $2-million in public money – the cash was earmarked for consultants’ fees and up-front design costs – bC recruited five Canadian developers whose task it would be to construct, at their own expense, 26 NZE case-study homes, prototypes ready for the market and suitable for future factory manufacture. Before the $4.2-million demonstration project was completed earlier this year, Construction Voyer had put up a three-storey, six-unit NZE condominium complex in Laval, and Minto Communities had done a detached NZE home and four townhouses in the Ottawa suburb of Kanata. Mattamy Homes constructed five detached houses in Calgary, while Provident Development and Reid’s Heritage Homes contributed five each in Halifax and Guelph, Ontario.
The efficiency of these houses has been largely promoted by the stepped-up use of familiar technologies and techniques and the establishment of a high-performing building envelope – nothing exotic or avant-garde – I was told by bC president Michael Lio and by Candice Luck, bC’s director of strategy and programmes and the project manager from the outset.

The NZE standards that each developer agreed to meet were designed during what Mr. Lio called “a national charette” held at the beginning of the process. All windows were to be triple-glazed. Rigid insulation in the walls, extra insulation under the roof and an exterior air barrier would curb energy leakage. An air source heat pump, effective down to -30 degrees Celsius, would be the principal device for warming the house, eliminating the need for a furnace. Power for appliances and lights was to be generated by photovoltaic cells installed on the roof.While such thriftiness is welcome anywhere, it might have been interesting to see how this venture in efficiency played out, say, in an inner-city high rise or a dwelling designed by an architect on the leading edge of his or her art. All in all, bC’s project has been a very suburban affair. The building sites are in suburbia. While a couple have also had experience with condominium towers, all the selected builders made their mark in the suburban, low-density housing market, and they have continued to do here what made them commercially successful in the past. The images I’ve seen of these NZE homes show entirely predictable façades and interior layouts, and nothing at all that expresses their sophisticated innards.

But if they remind one of sprawl, that’s because they are supposed to.“There is nothing odd about how one would live in one of these houses,” Mr. Lio said. “They walk and talk like regular houses. Our focus has been on production house design. Suburban style housing is the dominant housing form across Canada.”
Operating them effectively, however, will require common sense on the part of residents. “The houses are only net zero energy in simulation. If [the home-owners] keep the TV on all night, or sleep with the windows open, they won’t work.”

It is still too early to tell if they work as well as Mr. Lio and Ms. Luck predict. The last one went on the market, after all, only in February. Because NZE performance is calculated on a yearly basis, we won’t know for some time if these dwellings live up to their billing.Meanwhile, there are few signs that the Canadian housing industry is ready to change its mind about putting such houses on an assembly-line footing. For one thing, NZE is expensive. One of Mattamy’s NZE houses in Calgary, for example, has sold for $459,000, a price roughly comparable to that of an ordinary home in the neighbourhood. But, as Ms. Luck pointed out, the price-tag would have been 15 per cent more, had the developers not been subsidized to the tune of $2-million.

Nor does it appear that public regulatory regimes at the provincial and local levels are about to encourage NZE construction on a large scale.“There are huge barriers to seeing these houses built in large numbers,” Mr. Lio said, while maintaining that the project “demonstrated their technological feasibility in a production setting.” NZE for the millions, for the time being at least, remains an engaging, suggestive dream shared by many in government and industry, in Canada and throughout the world – but a dream nonetheless.

In the Fall 2016 Premiere Issue of Build Force Magazine, Sonja Winkelmann, Director of Net Zero Energy Housing at CHBA, writes about Net Zero Energy Homes and mentions buildABILITY’s role in the Net Zero Energy Pilot Project:
…
The five builders were supported by
a strong technical team that guided
them through the initial design process
and helped them address the
particular challenges of applying Net
Zero Energy construction in a production
building environment.The lead consulting firm was
buildABILITY, and was assisted by
energy advisors from across the country.
The process began with a design
charrette that brought builders and
consultants together to focus on how
best to achieve NZE by adapting
the traditional building techniques
and trades roles typical to a subdivision-
scale production building site.While a number of NZE homes had
been built in Canada prior to the pilot
project, most involved custom construction
approaches on “one-off” houses,
where a single team of trades and site
managers work together as a team,
through the entire build process.Production building relies on a more
sequential process where trades cycle
through a site, each carrying out a
specific part of the overall process using
standardized techniques. This results in
a high degree of efficiency, but makes
the introduction of innovative techniques
and a more integrative building process
more challenging.…

Mentoring Innovation with New Home Builders
Michael Lio
July 5, 2016
I took my first R-2000 workshop in 1982. Natural Resources Canada (NRCan) mounted these workshops to make builders aware of this new innovative way to build and also to demonstrate some of the new practices that define R-2000. Three facilitators (including one builder) talked about insulation, did live demonstrations on poly wrapping windows, and led multiple HOTCAN (HOT-2000’s predecessor) modelling exercises for the builders in the room. Thousands of builders attended these workshops over more than 20 years. Despite the enormous training effort, R-2000 housing starts never captured more than a few percent of the market.
What became clear later, when we introduced Energy Star into the Ontario market, was that it was completely unreasonable to expect builders to be able to understand and adopt complex R-2000 practices by attending a workshop. Perhaps the junior staff person, who was assigned to attend the workshop, understood the implications of adopting the innovation, but they could never communicate all of the implied changes to the rest of the company, let alone to the trades who actually built the houses.
Ten years ago we suggested to NRCan that workshops alone should not be relied on as means to facilitate change in the homebuilding marketplace. We suggested that workshops build awareness but that deep engagement and mentoring was needed with individual builders over an extended period of time to truly build enduring change. NRcan supported the Building Canada initiative to do just that. Building Canada engaged and mentored just 4% of registered Energy Star builders. These builders, however, labelled almost 50% of all of the Energy Star houses during that same period.

In March 2016, we completed the largest net zero energy housing community project to date (read more about it at www.zeroenergy.ca). In our commitment to share our learnings with the building industry, we’ve created a mini-video series to tell the story of our partners. Rheem Canada and JELD-WEN Canada were pivotal in helping our 5 builders achieve net zero energy performance. Rheem’s innovative Hybrid Heat Pump Water Heater and JELD-WEN Canada’s high performance triple pane windows are two key net zero energy technologies that every builder should consider. Take a look at these two videos to hear their story and learn more about the technology.
