BC Government funds Passive House education

Econ Group’s Marcel Studer was part of the ceremony in Victoria last week at which Bill Bennett, Minister of Energy and Mines, presented a $100, 000 ICE (Innovative Clean Energy) grant to Canadian Passive House Institute West for their Passive House education and certification efforts.

“This announcement is an enormously significant, clear message that the work and education we all in the Passive House community have been up to in the Vancouver area for the past decade, is beginning to pay off,” says Marcel.  “It’s really an exciting moment to be involved.”

The grant will support increased training and certification opportunities for construction and design professionals so that they can build the most energy-efficient buildings in the world, right here in British Columbia. It will help sponsor and subsidize introductory or certification courses in Passive House design principles offered by CanPHI West for up to 200 qualified professionals in British Columbia.

Econ Group has been building to the Passive standard for over a decade, and actually built the first residential Passive House in BC. Our next Passive House project breaks ground in North Vancouver in April 2015, with two others on its heals in May and in the summer. Learn more about Passive House technology at my previous North Shore News article on the topic.

The international Passive House standard is the one of the most rigorous and advanced building performance standards in the world, achieving reductions in heating energy of up to 90% compared to other buildings.

Passive House Catches On

Through the last decades, the notion of building homes in more environmentally friendly ways has become much the norm. Slowly but surely, at least here in Canada, the conversation has shifted onward from discussing why building technology needs to evolve to discussing how exactly building technology can evolve in order to most responsibly take on its own environmental inefficiencies. What once was considered alternative has now become quite mainstream.

Consider Vancouver Mayor Gregor Robertson’s Greenest City 2020 Action Plan target: “Require all buildings constructed from 2020 onward to be carbon neutral in operations.” Other municipalities around the world are setting the same tone: Melbourne officially became carbon-neutral this year, Copenhagen is pushing for the same by 2025, Seattle by 2050, the entire country of Costa Rica by 2021. According to Vancouver’s Action Plan, greening up construction practices here would mean big positive impact: “the electricity and natural gas that buildings use make up 55% of Vancouver’s greenhouse gas emissions.” Essentially, we need to get building green, and get building green mighty quickly! But we’re in luck…enter, Passive House.

The initial principles that eventually gave rise to the Passive House movement were actually developed here in Canada as part of the Saskatchewan Conservation House demonstration project of 1978. And though the project also stimulated the creation of NRCan’s R-2000 building certification program, the technologies and methodologies were never adopted into any municipal building code, thus slowing the positive momentum inside our borders. Instead, the findings took root in Germany and Passivhaus was born into receptive hands. Today, thanks in part to stricter environmental regulations driven by proactive policymakers, there are about 50,000 Passive House units worldwide.

At the heart of Passive House is not an overly novel idea. Rather than using old tires or straw bales (like some of its green building cousins), and rather than tallying vast arrays of enviro-scoring criteria (like some other of its green certification relatives) Passive House aims to do one thing extremely well. And that is: keep heat where it’s supposed to be.

In order to regulate temperature within the home, a more robust envelope is needed to make the building essentially airtight. Standard framing walls (see my Framing 101 article from 3 July 2013) are made to be super-insulated and double or more the thickness, windows become triple-paned, and solar orientation becomes paramount to success. The need for fresh air and moisture control is managed by a low energy active heat recovery ventilation (HRV) system. The impressive energy savings potential of Passive Houses (many use 90% less energy than traditional, to-code builds) is at the concept’s core, however, neither comfort nor affordability are overlooked.

A Passive House, absent of typical drafts, is kept at a constant temperature ever replenished with fresh air. Warming up the space even further literally means either inviting over a friend, turning on another light, or even just lighting a candle! How’s that for comfort?

And the costs to build Passive are coming down (as with any other newer technology engaged in the process of catching on and becoming the norm). In places like Germany (the first real adopter of Passivhaus), the incremental cost to build Passive runs under 5% more than a traditional home built to code.

As a wholly performance-based environmentally aware building methodology, Passive House utilizes energy modeling software to accurately predict how heat and energy will behave in a given (and unique) construction scenario. The design is then honed to produce the most optimal result based on the parameters of the site, etc.

With 2020 around the corner for our Vancouver area’s target to build only carbon-neutral buildings, Passive House offers a proven platform onto which photovoltaic solutions or the like can be added in order to supplement the small amount of active energy input required to become Net-Zero or carbon-neutral. It is a no-nonsense, science-backed solution that reduces our housing footprint while creating homes and communities that are built to last.

Merging the Greens: looking longer at Vancouver housing affordability

It’s no news that Vancouver’s average monthly carrying costs for a new home far exceed the 30% of household income mark of housing affordability. As RBC’s Economics Research arm reported in March 2012 owning a home at current prices would still take up a huge chunk (86% in the case of a bungalow) of a typical household budget. And while it is astonishing that Canada is still the only G-8 country with neither a National Housing Strategy nor a coordinated strategy on affordable housing, we are pleased at our City’s recent reinvigorated efforts to tackle housing affordability.

As a modern residential contractor doing business in Vancouver, Econ Group is well aware of the financial challenges in not only owning a home, but also in the underlying process of its construction. We live and work in a place where labour is not cheap, construction regulations are time-consuming and climate constraints are structurally demanding. In a nut-shell, and as elementary as it may seem, what is inexpensive to build in Regina might never be inexpensive to build here in Vancouver.

However, thanks to Vancouver’s Greenest City 2020 Action Plan we now all have a shared mandate which we must meet in order to even move forward with homebuilding. From 2020 onward all new buildings constructed in Vancouver will be required to be carbon neutral in operations. With 55% of Vancouver’s greenhouse gas emissions caused by the electricity and natural gas that buildings use, this requirement will be of enormous positive impact. What’s more is that while some may see this (“yet another”) requirement by the City as a further financial burden negatively impacting the bottom-line of affordability, Econ Group sees it all as an incredible opportunity to merge the two greens: dollars and ecology.

As with all other building materials, the costs associated with the wares of environmentally responsible construction are determined by the laws of supply and demand. The quicker that early adopters (both home-owners and home-builders alike) of the carbon-neutral mandate fully embrace utilizing materials standard to Passive House and Net-Zero building methodologies, the quicker the costs will come down to light the way to a future we all can truly afford.
