Report: ecoEII Net Zero Energy Housing Demonstration Project

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.

The Globe and Mail: Can Net-Zero Net the Average Homebuyer?

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.

Candice Luck honoured as one of Canada’s 2017 Clean50

for driving net zero housing innovation

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: Housing Consulting Group Pursues a Mass-Market Net-Zero Home

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.

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.

Why Trades Should Care About Net Zero

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.

Press Release: Canadian Net Zero Energy Home Builders Recognized for Contribution to Industry-Changing Demonstration Project

Thursday, March 10th, 2016

(March 10, 2016, Ottawa, ON) Canada’s elite net-zero energy (NZE) home builders gathered last night in Ottawa to celebrate and accept awards for their contribution to the largest Canadian net-zero energy (NZE) housing demonstration project by advancing building science and responding to the global climate change challenge.

A total of 26 homes were built in four provinces as part of the Net-Zero Energy Housing demonstration project with Natural Resources Canada (NRCan) and Owens Corning Canada.

The five project home builders (and community locations) are: Construction Voyer (Laval, Quebec); Mattamy Homes (Calgary, Alberta), Minto Communities (Ottawa, Ontario); Provident Developments (Halifax, Nova Scotia); and Reid’s Heritage Homes (Guelph, Ontario).

Parliamentary Secretary to the Minister of Natural Resources, Kim Rudd was on hand to congratulate the five builders and all those involved in the project

“With support from Natural Resources Canada’s ecoENERGY Innovation Initiative (ecoEII), five home builders and leading industry suppliers, we have proven that net-zero energy housing can be built using existing technology, at prices that are accessible to the average homebuyer,” stated Salvatore Ciarlo, Technical Services Manager, Owens Corning Canada. “Building entire net-zero communities is a viable, short-term goal”one that we are much closer to as a result of this project’s success.”

Mr. Ciarlo was joined by Kim Rudd, Parliamentary Secretary to the Honourable Jim Carr, Minister of Natural Resources Canada to present the awards.

“Congratulations to Owens Corning Canada, the five participating home builders and the many important players involved in this impressive project,” said Parliamentary Secretary Rudd. “Our government proudly shares your vision of energy-efficient home construction. These net-zero energy homes will reduce our environmental footprint, create clean jobs of the future and help Canada become a global leader in low-carbon energy.”

Measured over a year, a NZE home can potentially produce as much energy as the home consumes. This could mean an average annual energy bill of zero for its homeowner. Natural Resources Canada data suggests that housing accounts for 15% of the country’s greenhouse gas emissions. These NZE energy homes can significantly reduce Canada’s energy use, reliance on fossil fuels, and carbon and greenhouse gas emissions.

“A net-zero energy home loves you back,” explained Kevin Lee, CEO of the Canadian Home Builders’ Association (CHBA). “It shelters you from rising utility costs, it delivers exceptional comfort, it works better, and it lasts.”

Working with NRCan and the CHBA, the outcomes of the home designs and the learnings from the five builders will be shared and disseminated to the industry. This was not only a demonstration project to show that NZE homes are feasible in today’s market but it is also a knowledge transfer success story. Participants of this project do not believe that the NZE home recipe should be a secret. These innovative builders have become educators and mentors to their peers, sharing their learnings and designs at numerous building industry events.

“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.”

All the NZE homes will eventually be sold to the public. Beyond this project, these builders will offer net-zero energy-ready (NZEr) homes as a standard or an upgrade on a production scale for their next subdivisions“ featuring energy efficiency equivalent to their full NZE houses. Preliminary simulations show that some of these NZEr homes have an impressive 70% reduction in energy costs compared to comparable houses built to code. Solar panels to make them full NZE will be offered as an option.

“While the homes met the same standards to achieve net-zero, each community arrived in a slightly different way,” concluded Ciarlo. “This not only points to the ingenuity and skill of the local home builders, technical experts, equipment suppliers and tradespeople, but demonstrates that we are ready to build net-zero across Canada’s diverse climatic regions.”
