Green rater training at CaGBC Conference There are over 5,000 homes registered for LEED certification across Canada, and each requires third-party, on-site verification by a green rater. For new LEED v4 projects, these green raters must also be credentialed through the LEED Canada for Homes Green Rater program.

Those wishing to become a LEED Canada for Homes Green Rater need to complete the HOMES 401: Green Rater Training. Part of this training is being provided at a two-day workshop on June 4 and 5 in Toronto, in association with the Canada Green Building Council’s Building Lasting Change National Conference.

This interactive workshop is eligible for CE hours and provides training in: • Identifying responsibilities of a LEED for Homes Green Rater in each phase of a project.

• Managing and conducting verification activities.

• Effectively using the project checklist file.

• Communicating with project teams and LEED for Homes Providers.

• Applying the sampling protocol on applicable projects.

• Preparing accurate and complete certification submittal packages.

Date: June 4 and 5, 2014 Time: 8:00 a.m. - 5:00 p.m.

Location: Metro Toronto Convention Centre Info: Search on “HOMES 401: Green Rater Training”

Built Green Canada expands across western Canada Coinciding with Built Green Canada’s 10th anniversary, the green home rating system has expanded to Saskatchewan and Manitoba.

The expansion addresses the growing demand for responsible sustainability practices driven by builders, developers, government, and homeowners. Built Green’s programs recognize energy efficiency as a fundamental component and move beyond this to include electrical efficiency, water efficiency, indoor air quality, resource use, and overall environmental impact.

Built Green Canada is an industry-driven organization offering programs for single-family and high-density projects, with a renovations and a communities program under development. It is affordable, thirdparty certified, and easily implementable with pre-approved sample checklists and guides.

The organization is “by builders for builders”, so the programs are informed by the industry to ensure they are robust, credible, and achievable with pre-approved sample checklists and guides.

Since its inception, Built Green® has enrolled and completed over 20,500 Built Green® certified homes in Alberta, BC, and Ontario— including the units in multi-storey projects, the total is over 23,500. www.builtgreencanada.ca

Ottawa builder hits three Platinum houses Ottawa’s RND Construction has completed three homes that have earned the LEED Canada for Homes Platinum rating.

President Roy Nandram is a green building pioneer going back 20 years in the Ottawa area, and has the certificates and awards on his office walls to prove it. The oldest of these might be a framed certificate denoting his completion of a Canadian General Standards Board course on Insulating Homes for Energy Conservation nearly 30 years ago in 1982, many years before “green” was the buzzword it is today. He became one of the first LEED [Leadership in Energy and Environmental Design] accredited professional in 2009.

At first glance, it is difficult for an average person to identify a ‘green’ home or ‘green features’. To Nandram a green home typically uses less energy and water, fewer natural resources, creates less waste, and is healthier and more comfortable for the occupant. In a nutshell, green features of a home will dramatically reduce or eliminate the negative impact on our environment, and result in lower energy bills and better indoor air quality.

ecohouse CANADA | SPRING | 2014

“We use an integrated design process to get the team together and work towards a common goal,” he says. “Everyone needs to be thinking about sustainability from the start for a project to really be effective,” says Nandram.

RND’s eco-friendly construction starts with attention to details such as recycling discarded wood, repurposing disused materials and using low-VOC products at all times to reduce the impact of indoor air quality and the environment. Because of its recognized expertise, RND is as much advisor as builder on a project, often providing guidance for local architects, engineers, project managers, designers and subcontractors. www.rndconstruction.com

Powered by ions found in regular tap water, the clock easily keeps time thanks to two proprietary metal plates specifically designed for Bedol. Once the plates encounter water, naturally occurring positive [+] and negative [–] ions generate enough electricity to keep the clock ticking.

Located in the Grandview-Woodland neighbourhood of Vancouver’s east end, the original house was representative of the houses constructed during the early decades of the last century: poorly insulated, disconnected from the street, and with little natural light. The new owners - young professionals with modest funds and a new baby looked to transform the house to suit a contemporary lifestyle with an eye to sustainable building.

STRATEGIC DECISIONS While the project contains numerous sustainable strategies like low-VOC paints, high-efficiency fixtures, and in future may include on-site water reclamation, and solar hot water, the most important operation was the simple act of lifting the existing house to make livable the ground floor.

This radically altered the ground floor, introducing light and air, and changed the house’s relationship to the surrounding grade. It also preserved more than 60% of the existing shell of the house, saving construction costs directly and making for faster approvals with the City.

The success of the renovation could be a solution to the housing affordability problem in Vancouver – the idea of doing modest alterations in the city’s urban fabric rather than relying on grand, expensive ambitions.

For this renovation the owners maintained rigorous control

of both the budget and material and product selections to make the project possible. Limited by a modest budget, but with high sustainability aspirations, the project team rarely discussed the house in terms of ever being “complete”.

The finished two-storey house [1], and the original house [2]. Since the owners elected to maintain the majority of the existing house, they were not forced by the city to provide on-site parking.

THE INTERGENERATIONAL FAMILY HOME novel living concept wrapped in a passive design

1 Located between two major transportation bus routes and within walking distance of local amenities, the project combines three different living units connected by shared green spaces and gardens. The typical two-car garage is replaced by a laneway house and single carport [1].

Designing the framing in a 3D CAD program allowed for better detailing of the structure, reduced typical problems of thermal bridging, and brought better coordination of mechanical and electrical services [2].

The Intergenerational House is a prototype 3,000 sf energy-efficient residence inspired by multi-generational living in close yet separate quarters as can be found in Europe and Asia.

The design provides a three-storey main house, lower suite and a laneway house on a typical 33’ x 122’ Vancouver building lot with space allocated as: two adults and two children in the main house, grandparents in the spacious, lower two-bedroom suite, and tenants in the small laneway home, which could possibly house the children in future.

WORKING TO MAKE EVERY BUILDING GREENER

Thomas Mueller

Welcome to the LEED速 for Homes Canada in Review Supplement, the very first publication of its kind. We are pleased to be working with ecoHouse Canada and SABMag on this new feature, as we do with the LEED Year in Review publications each year. It is a great way of recognizing how far green home building in Canada has come in the past decade.

I am proud to say that there were a total of 1,013 registered and certified LEED for Homes projects in 2013.

The green home building market has been growing steadily over the past decade. I firmly believe that this success proves that more and more people are recognizing that living in sustainably built homes makes sense: for their wallets, for their health and for the environment.

The CaGBC is pleased to be giving credit to all of the professionals involved in the growth of the green home building industry and recognizing them for being at the forefront of green building innovation.

Thank you to those who have participated in this supplement, and congratulations on contributing to projects that give Canadians healthier homes in which to live and raise their families.

Thomas Mueller President & CEO, CaGBC

12R04_Cohabitat Québec Founded in 2001, Québec City’s TERGOS Ecological Architecture + Construction is a leader in sustainable residential design and construction.

With six LEED for Homes Platinum buildings, TERGOS redefines the way we live today, whether in be in the city or in the country.

Specialised in new high-end homes, residential enlargements and major renovations, TERGOS is equipped to make every project ecological and sustainable. From the tiniest makeover to major multifamily housing developments, TERGOS distinguishes themselves with a resolutely contemporary architecture.

Winner of Québec City’s prestigious Mérites d’Architecture Awards 2013 in the Residential New Building – Mid and High Density Housing, Cohabitat Québec distinguishes itself on many levels. Composed of five independent LEED for Homes Platinum buildings, the province’s first Cohousing project has gained the respect of the city’s municipal officials and other professionals province-wide.

The colossal mandate was to insure that within the limited budget, the 42 unit housing project attain the CaGBC’s highest LEED standing.

With an average building cost of 130$/square foot, TERGOS has proven with Cohabitat Québec that it is not only possible to attain a high performance and ecological building at market construction costs, but it is also possible to exceed the country’s average energy housing performances and build significantly more beautiful buildings in which to live.

Major criteria used in designing and building the development include: • Superior quality of construction details; • Passive solar orientation; • Integration of a recycled industrial building in the design; • Use of local, healthy, natural, recycled and recyclable materials; • Superior building envelope, attaining the province of Québec’s Novoclimat standards; • Excellent resource management; • Aesthetics and acoustical comfort

HAWKINS PASSIVE HOUSE Driven by the belief that highly energy-efficient homes should be available to people with modest construction budgets, we created the Hawkins House. As the first certified Passive House in Canada, we used it to develop the techniques and materials that have now been applied on several other high-performance homes in our climate. We were able to achieve this for such a small increased capital cost that the combined mortgage and energy bills are the same as in code-built houses of a similar size.

Once it became clear that we would hit the Passive House targets, adding LEED for Homes certification was a logical next step. By combining the very rigorous energy standards of Passive House with the more holistic credits of LEED, Hawkins House is one of the greenest homes in Canada.

Using conventional building materials in unconventional ways, we were able to hire contractors who work in the production home market. The speed and efficiency of these trades combined with careful design and detailing was our key to cost effectiveness. The result is a house that looks and feels like a regular home, but has a total heating bill of under $200 annually. The temperature inside will hover around 15 degrees during the coldest months of winter with no heating at all. That, combined with the ample daylight, good indoor air quality, and attention to age-in-place accessibility, ensures that this house will be highly desirable for many decades to come.

Passive House E-Design, with the help of third-party certification and commissioning from our colleague Jordan MacDonald at ThermalWise, has been pioneering the design and construction of the greenest homes in Nova Scotia. We’re proud to have built the first certified Passive House in Canada, and are continuing the work of making ultra-green homes accessible to everyone.

Dueck Homes Dueck homes began with a mission to bring affordable green Homes to Winnipeg. Their very first house was built to Manitoba Hydro’s Gold power smart standard, and they have never looked back.

Shortly after they built their first homes, they registered to be R2000 builders. Then, when a client asked them to build a LEED registered home, they were more than ready to proceed.

According to Dueck, they had already been building most of their homes to a LEED standard. Now it was just a matter of documenting the process and verifying the LEED eligibility of the various components.

The Parker house was designed to reach the Gold LEED standard. However, since the geothermal was not installed as of the test date the house was awarded Silver. The Geothermal field was installed but not connected until a few years after certification.

Many of the standard features in a Dueck Home were employed in the LEED home. For example, the insulating materials used are Cellulose and Polyiso. The Cellulose was “dense packed” into 2x 6 “smart framed” walls and used to a depth of R60 in the attic. Three inches of Polyiso was used under the basement floor, resulting in an R18 rating. An inch and a half of Polyiso was also used on the outside walls so that they ended up with an R32 rating. The Polyiso also provided a complete thermal break for the house by connecting to the foam on the ICF basement walls.

ecohouse CANADA | SPRING | 2014

Other energy saving features include large south facing 2 low E windows, grey water recycling, grey water heat recovery, energy efficient HRV, and LED and florescent lighting. As in all Dueck Homes, no OSB was used inside. The main floors areas are covered with engineered elm rescued from the local city dump and treated with a zero VOC finish.

A home built to LEED standards results in a happier, healthier home. Make your next home a Dueck Home!

HRVs ERVs Essential components of a high-performance

Energy recovery from exhaust air is becoming common place in cold regions, and two types of equipment can do this- an HRV [Heat Recovery Ventilator] and an ERV [Energy Recovery Ventilator].

Both HRVs and ERVs are somewhat new to mainstream home construction, and can often be confused.

In an effort to clear that up, we will first explore why ventilation is so crucial, then explain the options and their best applications.

Up until the last few decades, houses were so leaky that sufficient cold dry air seeped in to meet the needs of occupants, and ensure homes had no moisture damage. These houses were said to ‘breathe’, but that would be like breathing through your skin instead of through your nose.

It meant that cold, dry winter air would need to be warmed as well as humidified, while hot and humid air would enter in the summer.

Nowadays, in the name of energy efficiency, houses are built to much higher standards of air tightness, so a mechanical ventilation system is essential for the following reasons: To provide oxygen for occupants since people deplete oxygen as they breathe. In a reasonably airtight home with no ventilation you would feel the effects of that in quite short order.

To remove contaminants – because along with the toxins emitted by the human body [ammonia, benzene, carbon monoxide and methane to name a few], chemicals in building materials and furnishings continue to

Whether natural or mechanical, ventilation in homes is a must. Houses are no longer built to leak heat and moisture the way they used to be; we now build them as airtight as we can. This makes mechanical ventilation essential in a high-performance home.

How much fresh air is enough?

It is very difficult for humans to detect low levels of health hazard. An ideal ventilation system would include sensors that could detect the presence of excessive humidity and all harmful agents in order to provide fresh air accordingly, but no such system exists yet.

air supply at all times. Most building codes rely on the *ASHRAE standard 62.2 [or some variation of it] to establish ventilation norms for homes. *ASHRAE [American Society of Heating, Refrigeration and Air-Conditioning Engineers] is the most respected and authoritative source for interior air quality standards. ASHRAE 62.1 and 2 are the recognized standards for ventilation and indoor air quality [IAQ].

1 According to Ecohome’s engineer Denis Boyer, in most parts of Canada with very specific building dimensions, orientation and window design, the sun can provide sufficient heat to keep a house around normal room temperature with no auxiliary heat source, even in the dead of winter.

Using regionally-specific climate data [average temperatures, sun hours and cloud coverage] and analysing it through Passive House Planning Package software [PHPP], Ecohome can determine the thermal performance and design parameters required to achieve 0 kWh of heat demand in a given location.

While they have several homes in the design phase, there is only one NZH house standing so far, and with that Ecohome

quick to point out that aiming for zero heat demand is not always recommended for the good of the planet or your wallet. There may come a point where you are best to stop insulating and start heating, as in some cases you man not recoup the financial investment nor the energy used to produce added insulation.

“This is not a rigid system intended to chase a goal at any cost” says engineer Denis Boyer, “The shape, wall assembly, orientation and location of your home may mean your lowest impact and best return on investment happens by limiting insulation at a given point, and adding a bit of heat. The intent of this program is to help you find that point.”

The Net Zero Heat program pays homage to the Saskatchewan Conservation House built in 1977, and recognizes any home that can at least match its performance of 75 kWh per square meter per year of heat requirement.

Our web partners at Ecohome.net have recently taken passive heating and cooling to a new level, and released a program called Net Zero Heat [NZH]. It is a rating system unlike most others, as it is also a design service that promotes an entirely new philosophy in home design.

Aiming for zero heat demand is not always recommended in Net Zero Heat design, as economics may dictate that at a certain point it’s best to stop insulating and start heating. Net Zero Heat is about finding that point. [1]. Photo: Erin Warder, Architect: Andrew Reeves. The Kenogami House in Saguenay, Quebec is the fist house designed using the Net Zero Heat concept [2].

CoolTouch – Technology that ensures the entire outer surface never exceeds your preferred shower temperature. An innovative cooling channel creates a barrier between the hot water and the chrome surface – so it’s never too hot to handle.
