Message from the Alberta Chapter of the CaGBC The Alberta Chapter – CaGBC strives to transform Alberta’s built environment into sustainable homes, schools, offices, facilities and communities that minimize our carbon footprint while providing leading-edge environments for us all to enjoy.

Through education, advocacy, training and communication, the Alberta Chapter leads and accelerates Alberta’s transformation to high-performing, healthy green buildings and communities.

In addition to the impressive gains in LEED certifications, the Alberta Chapter has introduced a number of innovative ways of spreading the green message. Examples include:

Tools and initiatives include the LEED rating system, the Living Building Challenge, Passive House, Smart Growth, Eco-Districts and the newly formed Canadian Green Schools Coalition. As well, the Chapter’s annual flagship event, the Alberta Sustainable Building Symposium, has become the province’s premiere green building event, attracting decision-makers from all segments of the design and construction industries.

• the inaugural Alberta Green Apple Day in September 2013 at Okotoks’ Westmount Elementary School, focusing on the buildings where students learn, • the inaugural Alberta, and first international, Hack-a-Thon in November 2013, offering superior experiential education for professionals looking to qualify for LEED LEED-specific Continuing Education, and

Consider some of our other recent successes: • Roughly 9% of Canada’s LEED professionals reside in Alberta [1,077 in Alberta, 12,000+ in Canada]. • In 2013, Alberta LEED certified 3.3 square feet per capita. That is more than the U.S. state with the highest per capita rate of LEED certification. • As of Aug. 31, 2013, 100 of Canada’s LEED-registered schools were in Alberta - almost a quarter of all Canadian school projects. • To date, Alberta: - owns 209 of Canada’s total 1,573 LEED certifications, - was the first in Canada for registered LEED project area per capita, at 31 square feet/capita

• the current EcoHouse Design Challenge, inviting student and professional teams to design the ultimate eco-friendly house using recycled and/or materials available regionally. These achievements and initiatives represent tremendous commitment especially from our very generous sponsors and our volunteer Board of Directors. Without the sustaining support of these individuals, the leadership and innovation for which the Alberta Chapter has become known would not be possible. Thank you all. Finally, I look forward to seeing a record number of delegates at the 17th annual Alberta SBS, held this year again in Calgary. Look for program details in this issue of SAB Magazine. The one-day event again promises to refresh, inform and even entertain. Sincerely,

• In the past two years, the CaGBC and its Alberta Chapter provided over 20,000 hours of green building training and education to students and green building professionals.

for future and current generations results from the first 50 provincially funded green buildings show excellent performance in saving water and supporting regional industries it’s hard work, changing the way we do things every day to have a smaller ecological footprint. the government of Alberta is committed to being environmentally responsible in the face of the status quo, to act when we know better. We aren’t afraid of hard work. green buildings are the government of Alberta story that showcases how much Albertans care about the environment. Since 2006 all government of Alberta funded buildings have been required to meet Canada green Building Council’s LEED® Silver for green building design and construction. We currently have 63 LEED certified buildings including two with platinum certifications. Of the first 50 LEED certified buildings, all have used at least 10 per cent regional materials, 42 of the 50 have used at least 20 per cent regional materials and 23 of the 50 have achieved exemplary


performance above that 20 per cent mark. All 50 buildings have used at least 15 per cent recycled construction materials and all have used low-emitting materials including paints, coatings, sealants, carpets and wood products. this makes sense as we Canadians spend 90 per cent of our day indoors. We use LEED to help us target high-energy performance in our new buildings. government of Alberta buildings use an annual average of 1.6 gigajoules per square metre and have been declining in annual per capita energy use for the past seven years. We also strive for excellence in water conservation, using at least 30 per cent less water when compared to the LEED baseline. Our green buildings encourage and support environmentally friendly living and learning.

Fresh spin on old technology provides alternative way to heat Calgary buildings

there’s an alternate way to heat buildings in Calgary’s East village and downtown core. throughout the area, building owners and operators and architects are choosing to replace traditional onsite boiler systems with heat from EnmAX Energy’s Downtown District Energy Centre (DDEC). “people are choosing DDEC because it’s more efficient, has fewer emissions and is more cost-effective than conventional heating systems,” explains pat Bohan, Director of District Energy Business Development at EnmAX. “We monitor and manage both our heating supply and the heat exchange systems in our customers’ buildings 24 hours a day, 7 days a week – meaning our customers can rest easy.” District energy, or district heating, traces its roots back to hot waterheated baths and the greenhouses of ancient rome. hot water produced at a central facility is distributed through underground pipes to buildings connected to the system, using a heat exchange interface between the piping system and buildings’ heating systems. this creates a closed-loop system that takes up much less space in the buildings. While district energy is relatively common in other parts of Canada and the United States, the DDEC is the first of its kind in Calgary. EnmAX is currently supplying heat to City hall, Bow valley College and the hillier Building, with more on tap to join our district energy system soon. DDEC will be capable of supplying heat for up to 10 million square feet of new and existing residential and commercial properties. Contact us for more information and join us to learn how you can bring district energy to your building. Contact

The DDEC was recently granted Silver Level LEED® Certification. “From the beginning, ENMAX planned it with an eye for a low impact design that increases energy efficiency,” said Pat. “This designation affirms our efforts to build with the environment in mind.”

schools the Alberta government is pursuing.

these strategies go beyond best practices to keep learning spaces comfortable, while using as little energy as possible. the mechanical engineer team at Stantec placed air diffusers at a lower level near students and staff and in some cases adjacent to each other. the CFD models confirmed appropriate air distribution within the classrooms and that the classroom’s temperature, temperature gradients, air speed, humidity ratio and CO2 concentrations meet the thermal comfort level.

Vertical cross-section of classroom air Velocity (metres/second)

the use of CFD definitively demonstrated that the designed Dv system is effective and has the capability to meet the thermal comfort requirements specified by Alberta infrastructure and AShrAE standard 55.

By striving to exceed standard best practices we can design and create indoor environments that promote heath, wellbeing and productivity — enhancing the learning experience for students and staff.

Net Zero prototype for Habitat for Humanity brings fresh ideas for affordable housing

Can a sustainable home be affordable? That is the question Stantec, Lafarge, and Habitat for Humanity set out to answer with the development of a Net Zero energy duplex in Edmonton.

1 - Lafarge and Stantec partnered to design the first netZero energy precast concrete home in north America, which is targetting LEED® platinum certification.

By Klaas Rodenburg

the habitat net Zero prototype was developed as a collaborative project supplying a social, innovative, and affordable housing option to urban infill developments. this project was constructed as a pilot project allowing all parties involved in its development a chance to further refine the and reflect upon strategies that were implemented to supply Edmonton’s habitat for humanity with their first net-zero home. the project explored the collaborative development of a precast concrete housing unit that would be manufactured by Lafarge and donated to habitat for construction as a prototype on an Edmonton infill site. inspired by the unique properties of precast concrete construction, an innovative design was sought to reinterpret and challenge habitat’s current construction layouts, including a lofty ambition of attaining net-zero status.

Thinking Outside the “Wooden” Box What started with a simple lunchtime conversation between the team involved soon grew into a vehicle for innovative thinking about high-performance buildings. Lafarge wanted to prove that pre-cast concrete is a viable alternative to


the traditional wood- frame house. habitat for humanity had a standard plan for a duplex home – 1060 sq. ft. on each side – that they can build on single lots or small infill communities at a very economical price. that is where Stantec’s design team started. By adopting a standard model, it was possible for our team to compare prototypes by capital cost and performance throughout the life cycle of the homes.

2 - Casting the walls. Load bearing and non-load bearing exterior wall panels vary in thickness from 14” - 17” in thickness but both sections include 8” thick layers of continuous insulation.

the design team decided to explore the full potential of concrete. the fluid nature of concrete and its ability to record the shape and texture of the precast forms allowed us to explore a wide range of alternatives to standard bed liners. this eliminated the need for vinyl siding on the outside or drywall on the inside, which reduced the cost and construction waste.

Solar Photovoltaic System: photovoltaic panels are sized and positioned on the roof in an orientation that will provide adequate electricity production on an annual basis.

Green walls: precast planters allow the native landscape plantings to converge with the facade and be brought up to second floor operable windows. planters utilize rainwater collected and drained from the second floor roof.

Solar hot water collectors: are group with the photovoltaic panels to satisfy the homes hot water needs. Green Roof: The high bearing capacity of the hollowcore roof structure allows for green roof plantings to occupy the roof in areas not required for solar collection.

Hydronic In-Floor Heating: Fed by the geothermal loop, water is circulated through the interior of the structure.

Net Zero systems

Geothermal Loop: A geothermal loop is shared between living units and assists in providing a thermally comfortable interior environment

Going Mod modular wall panels gave us the opportunity to create a modern aesthetic with an exterior design that can be integrated into any community. At the same time, the modular wall panels offered sustainable features such as durability, living exterior walls, a “cap” for solar panels, and enough structural strength to house a green roof [although that option was not pursued for this project. meanwhile, the ultra-high performance of the foam sandwiched between two layers of concrete provided an excellent exterior envelope.

LEED v4 in Canada What’s Coming and What it Means to You The Canadian green building market has evolved rapidly over the last 10 years. There are now over 4500 LEED projects registered in Canada, of which over 1500 are certified. The Canadian green building industry and LEED have driven continual improvements in building construction and operation and maintenance meanwhile making real impacts on energy and water consumption, waste reduction and occupant well-being. LEED was always intended to evolve with the market, and LEED version 4 (LEED v4) is about taking the next step towards market transformation and raising the ceiling of building performance.

Parkland NetZero House

DESIGNED TO PrODuCE ITS OwN ENErGy The Parkland NetZero project is a certified LEED Platinum, single-family home in Parkland County just south of Spruce Grove, Alberta. The two storey, 4,025 square foot home acomodates a couple and their three children with a secondary suite. By Peter Amerongen

ThE PrOjECT AIMED TO AChIEvE fOur kEy OBjECTIvES Net Zero Energy: the project was designed to produce all of its own energy for heating, hot water, lighting and appliances, on site, over the course of a year. the designers were guided by the passive house idea that reducing building envelope losses and using passive solar strategies could be partially paid for by savings from the consequently smaller and simpler mechanical systems. The aggressive conservation measures: of the passive house approach were also the most effective way to reduce the size of the photovoltaic array required to meet the annual heating needs. the end result is a house that is predicted to use only 23% of the energy required for a similar home with conventional construction. heating and domestic hot water loads loads have been reduced to the point where it is more economical for them to be provided by a grid tied photovoltaic system. Reduced Environmental Footprint: materials and strategy decisions were vetted against a comprehensive matrix of environmental considerations: embodied energy, environmental impacts in manufacture, effect on indoor air quality, proximity of manufacture, durability, recycled content, and recyclability. Demonstration: the owners felt a responsibility to demonstrate that it was possible to make these deep reductions without sacrificing beauty and comfort. they have hosted numerous public open houses, and guided tours. On-going monitoring will tell whether it reaches the net zero energy goal.
