RAIC REPORT By Angie Sauvé RAIC Member Communications Specialist

A NATIONAL VOICE FOR ARCHITECTURE The Royal Architectural Institute of Canada [RAIC] is Canada’s national advocacy association for architects and architecture. Over the past year, the RAIC and its members have worked on issues concerning fees, contracts and selection processes as well as sustainability, heritage and reconciliation with Indigenous people. As a national body, the RAIC spreads the message that architecture matters through the involvement of its members, among them architects, graduate architects, academics, interns, students, retirees and allied professionals. In 2017, the RAIC joined with architecture organizations around the world to reaffirm a commitment to the Paris Agreement to mitigate global warming through good design. It made recommendations on the Pan-Canadian Framework on Clean Growth and Climate Change; and appeared before the Senate Standing Committee on Energy, the Environment and Natural Resources with recommendations for transitioning to a low carbon economy. Also in 2017, the RAIC Indigenous Task Force held Canada’s first International Indigenous Architecture and Design Symposium. It was at the symposium that a group of members decided to make a proposal for the 2018 Venice Architecture

Biennale; it was accepted, and they will represent Canada with a project called UNCEDED. As an association of peers, the RAIC brings together people who study complex issues and develop targeted and insightful approaches to affect change. RAIC members lend their expertise to groups such as the Age-Friendly Housing Options task force, the Committee of Regenerative Environments, and the RAIC Emerging Practitioners, who are focused on the interests of students, interns and newly licensed architects.

Bergeron Centre for Engineering Excellence Creative facade wraps high-performance envelope Located on a campus of 104 buildings and 10 million square feet, the Bergeron Centre for Engineering Excellence has recently become York University’s first LEED Gold certified building. The facility provides a holistic platform to educate the next generation of ‘Renaissance Engineers’, creative problem solvers and entrepreneurial leaders with a social conscience. By Paul Stevens

The bold architecture of the Bergeron Centre is a metaphor for creativity. Evoking the properties of a cloud, the undulating façade is comprised of a series of triangles positioned according to a complex algorithm. The façade reflects light and pattern while at the same time minimizing the window-to-wall ratio of


the building envelope. Through a highly integrated and collaborative process, the design team was able to attain LEED Gold certification, a first for York University and a considerable achievement for a facility of this size and type. The Bergeron Centre is a highly technical building with a significant infrastructure requirement to deliver a lab-intensive program. Energy conservation strategies included a focus on achieving a high-performance building envelope. Specifically, the window-to-wall ratio was minimized to allow for greater overall insulation and an increased wall thickness. A vegetated roof adds to the insulation value of the roof. Beyond these energy conservation measures, the sustainable design strategy was based on sustainable site development, materials management, waste diversion and innovation credits that included an extensive public education and outreach program. The university is undergoing a transition from a suburban, car-based campus to one that is more urban and sustainable. In keeping with this goal, the building is located on a former parking lot. Optimal orientation was determined using detailed microclimate analysis, and the building footprint was minimized by stacking the program vertically. The project transforms what was a “back of campus” site into an entry point linking two major pedestrian routes and ensuring continuity of the public realm that leads to the University’s recently completed subway station. These strategies are important, as more than 80% of commuters now travel to York by public transit, walking, cycling or carpooling. The design brings the student community together using streetscape furniture, planting strategies, sheltered courtyards and night sky friendly lighting.

Located adjacent to an established naturalized storm water catchment area called Stong Pond, the project involved extensive consultation with the local Conservation Authority extending the naturalization strategy beyond property lines to create a contiguous ecosystem. All storm water not used for irrigation follows a naturally draining system of holding and water polishing ponds. Bird and small mammal habitats established around Stong Pond were enhanced. Planting comprises drought-tolerant grasses and low ground cover, together with local trees that reinforce the existing species mix. The extensive vegetated roof is an important water management tool but also a highly visible ecological and educational component of the project. It exceeds the minimum size mandated by Toronto’s green roof bylaw. Daylight strategies are designed both to save energy and to enhance occupant wellbeing. Occupancy sensors are installed in interior areas, while daylight sensors are used in perimeter areas. Full cut-off ‘dark sky’ LED lighting is used externally. Operable windows were not considered, as all laboratory areas require positive air pressure for exhaust ventilation. Therefore, CO2 sensors are used to regulate air change rates in classrooms, meeting rooms and labs.

Inverting typical campus layouts, student wellness and productivity drove the design process, optimizing spaces for learning, discovery and interaction. Students have access to the best and brightest spaces, while offices are located within the core. Welcoming, flexible social spaces for student gathering frame the entrance, offering panoramic views of the surrounding campus. Echoing a tech start-up, the Bergeron Centre includes a Design Commons, where students are encouraged to gather, discuss and develop entrepreneurial ideas. Social spaces adjacent to research and academic areas facilitate the cross- pollination of ideas. Even corridors are places to learn with small niches and white boards for around-the-clock brainstorming, creating, critiquing and promoting spontaneous dialogue. Recycled materials that could be sourced with minimal to no incremental cost were identified early in the project, and included materials such as structural steel, cast-in-place concrete, gypsum board, carpets, concrete blocks, unit pavers, steel studs and doors. Almost two -thirds of wood products used were FSC certified. The use of native plants in the exterior landscaping enabled the project team to dispense with an irrigation system. Internally, the use of low-flow plumbing fixtures resulted in a significant reduction in the use of potable water. In order to share the sustainable design strategies with


building users and visitors, an audio tour of the building was professionally recorded and has been made available as a downloadable podcast on the university website. Following the success of the Bergeron Centre, York University has decided to support the Paris Agreement on climate change, and to pursue Passive House or Net Zero Energy standards on future projects.

How radiant heating and cooling is transforming high-performance building It is no surprise that as more and more building owners are placing increased emphasis on sustainable and responsible building practices, engineers, architects and designers are looking beyond traditional HVAC solutions to maximize energy efficiency while maintaining occupant comfort and safety. One system that is seeing increased growth in commercial applications is hydronic radiant heating and cooling. Over the past decade, the number of radiant heating and cooling systems designed, installed and commissioned has increased dramatically. These systems are gaining exposure and popularity for a variety of reasons. They can provide greater architectural freedom, superior comfort and more effective control of ventilation. The main driving factor in the increase in radiant systems, however, is the potential for improved energy efficiency. In a radiant heating system, warm water circulates through a series of crosslinked polyethylene [PEX] piping loops embedded in the concrete floor. The flow rate and temperature of the water is controlled to regulate the temperature of the thermal mass. The warmed surface radiates heat to the objects and occupants in the space, creating a comfortable environment. This same principle is used in radiant cooling; the difference is in the temperature of the water being circulated. By controlling the slab temperature, a radiant cooling system can effectively manage all or a portion of the structure’s sensible load, thereby reducing the total demand placed on a forced-air system. Radiant systems can reduce overall building energy usage in a number of different ways. For one, because the heat-transfer capacity of water is much higher than that of air, a radiant system that uses a circulator to move water [in lieu of a fan to move air] can achieve the same heat transfer using significantly less energy. Also, because of the way the human body exchanges heat with its surrounding environment, a radiant system can achieve comparable levels of comfort at lower room temperatures for heating and higher room temperatures for cooling. In fact, studies have shown total energy savings for typical office buildings on the order of 17 to 53 percent. As building owners and jurisdictions continue to demand high-performance buildings, system designers are looking for sustainable solutions to reduce energy usage, while maintaining function. By taking advantage of a building’s thermal mass, an embedded-tube radiant system can be an effective and energy-efficient alternative to a conventional forced-air-only system.

The recently completed Bois Ellen Co-op is located in the City of Laval near the Place de la Concorde train and metro station, a neighbourhood that is in transition toward multi-residential housing. Contrary to current trends that rely heavily on active renewable technologies, the design that emerged from the Integrated Design Process [IDP] focuses on passive design measures to ensure that ongoing maintenance is easily manageable for the Co-op and its residents.

By Daniel Pearl and Cecilia Chen 1 - South-east courtyard facade looking up, shows the low-tech pre-heating solar air wall.

Construction detailing and energy efficiency on a budget The L-shaped building has a six-storey senior’s wing


along Avenue Robert-Élie [with a dining hall opening to a central courtyard] and a 13-storey wing along the northwest edge of the site. Housing both seniors and families, Bois Ellen integrates knowledge, experience, and critical lessons learned by the architects on their previous largescale community housing projects. What may prove to be the most valuable aspect of the project is the deliberate strategy to encourage the residents of Bois Ellen to become the advocates for this creative and affordable housing model with the hope that it can be replicated across Canada. This strategy emerged from open dialogue and active listening between the design team and the residents. Both wings are cast-in-place concrete structures clad in a combination of brick and metal panels tied back to light steel framing. The technical innovations at Bois Ellen are focused on three major themes : • a significant improvement in building envelope performance – with an ‘exterior blanket’ approach to insulation, promoting energy efficiency, thermal comfort, and excellent building air-tightness, rarely seen in Canada for affordable housing at this scale • the simplification of the buildings’ mechanical sys-

• a pro-active, streamlined approach to passing on building operations to the residents via education sessions, ongoing dialogue, continuous monitoring, iterative adjustments, and gradual handover of the various procedures for the different seasons and circumstances.

The project was completed on budget, with a premium less than seven percent above conventional affordable housing. This included an extensive life cycle analysis of the building envelope, and enhanced quality assurance procedures. The envelope design incorporates clear and careful detailing, as well as specifications to increase effective thermal resistance and comfort; investment in the best window and door units within the budget, with coatings tailored to solar orientation; window and door installation details that increased comfort and reduced thermal bridging and condensation risks; insulation placed fully outside of the steel stud wall structure spanning

rigid insulation and fibreglass re-bar; solar-shading devices on south-westerly façades; and careful insulation and air-tightness at all exterior wall penetrations required for electrical and mechanical systems. Key to meeting and exceeding the Passive House standard for air-tightness was the pride taken by the trades responsible for building the exterior envelope. The co-op was fortunate to have a general contractor


excited by the envelope challenge, and motivated by the specified performance clauses and penalties.

A NOTE ON ENERGY USE The final post-construction energy simulation by EnerSys Analytics predicts the total energy consumption for Bois Ellen to be between 130 kWh/m2/year and 140 kWh/m2/year, or about 30 to 35% better than typical new construction in Quebec. Depending on numerous factors [including education, resident user patterns, etc.], energy use could be further lowered by another 10 to 15%.

Saanich house meets Net Zero Home Labelling Program

1 - Ocean front East-facing elevation.

In May of 2017, the Canadian Home Builders Association [CHBA] officially launched its Net Zero Home Labelling Program, following the successful completion of a 15-month pilot to validate technical and administrative procedures. The Program provides the industry and consumers with a clearly defined and rigorous two-tiered technical requirement that recognizes Net Zero and Net Zero Ready Homes, and identifies the builders and renovators who can provide them.

In this way, the program supplements the existing Energy Star and R-2000 certifications, encouraging developers and builders of single-family houses and small multi-unit residential buildings [MURBs] to raise their own standards, and those of the industry as a whole. A network of CHBA NZE Qualified Service Organizations, Energy Advisors and Trainers is being established to work directly with the builders and renovators to design, model, test and inspect the homes, as well as to deliver the required training. The CHBA NZE Building Science Training is mandatory for participation in the CHBA NZE Labelling Program. The training

FIRST NET-ZERO LABELLED HOME The first home in Canada to receive the CHBA’s NZE label is located in Saanich, BC. Designed by Ryan Hoyt and built by Falcon Heights Contracting, the three-storey, 4,500 square foot house steps down its sloping oceanfront lot, maximizing views from each level. The main floor has grade access from the road, and includes the living room, kitchen and home office. Family and guest bedrooms are located on the upper floor, while the full-height basement contains leisure and social space that leads out to a barbecue terrace. The main floor living space is open plan to maximize daylight and views to the ocean, while patios and decks are strategically placed to optimize views, provide shelter and maximize privacy. The house is rectangular in plan, with the longer north and south elevations facing the property lines, the east elevation facing the ocean, and the west elevation screened from the road by a detached garage. The net zero energy strategy began with the compact plan and a high-performance, airtight building envelope, including triple-pane windows and doors, with a solar heat gain coefficient of 0.18 and a North American Fenestration Standards [NAFS] performance grade rating of PG50 Plus.

2 - Steel, timber, and glass breezeway connects garage to house. 3 - West-facing private garden. 4 - Curved lines, timber accents and custom millwork are harmonized throughout.

The roof is insulated to R-65 insulation, and the walls to R-40 insulation, including two inches of continuous mineral exterior insulation. Careful attention to the continuity of the air barrier has resulted in an air change rate less than 0.7 A.C.P.H. The high levels of insulation, together with the optimization of windows elsewhere, enabled the design team to glaze the


east elevation completely, while still achieving net-zero performance overall. Energy efficient mechanical and electrical systems include: a GREE air to water heat exchange unit, [equipped with Tekmor controls] that supplies radiant heating and cooling through an in-floor hydronic system; drain heat recovery; a ductless condensing clothes dryer; and a combination of LED and low voltage lighting systems, controlled by daylight and motion sensors. Having reduced overall energy demand using the above measures, the remaining energy requirements are met using a solar thermal installation for domestic hot water, and an 11KW roof-mounted photo-voltaic array. The garage also has an electric car charging station. The house takes advantage of BC Hydro’s Net Metering program, enabling surplus electricity generated during the summer months to be sold to the utility, then bought back should there be any shortfall in the winter. After one year of operation, the house has a net energy consumption of 0-gigajouels.

For the sixth consecutive year, a graduate from the British Columbia Institute of Technology’s Architectural Science program has won the national CaGBC Student Project Award. This year’s winner, Andrew Martins, joins Ashley Hu [2016], Jason Reid [2015], Alison Walker [2014], Albert Lam [2013] and Simon Vangrootheest [2012]. The objective of the Award is “to recognize a student project that demonstrates leadership, innovation, inspiration and a creative vision for the future of sustainable design in the field of green building and communities” - a national challenge where this small degree program consistently succeeds. By Jody Patterson and Matthew Woodruff In 2016, to recognize the sixth consecutive win from one program, CaGBC also granted the 2016 Academic Leadership Award to program head Ron Kato. This string of success has led us to reflect upon the way in which sustainability is taught in our program, to see if there might be useful clues for other schools or the profession as a whole. Our conclusion is that the tight constraints of our program, the choice to prioritize sustainability as a fundamental design driver, and the explicit adoption of a laddered thinking model are distinct characteristics of our approach, which, when combined with a thoughtful and passionate student body have all contributed to this success. The Bachelor of Architectural Science at BCIT is a compact two-year program, on a 2+2 model: students completing BCIT’s two-year Architectural and Building Technology [ABT] diploma or equivalent may be admitted to the degree program. With a small, aligned faculty of six instructors [the majority of whom teach part-time and continue to practice], the program is characterized by a small cohort up to 24 students with a strong foundation of hard technical skills, and an intensive program of in-class instruction which emphasizes sustainability in every course. This approach gives us the opportunity to support students in exploring sustainability through the gamut of analysis, precedent, and technical performance in all core courses. Most importantly, in design studio courses we seek to develop students’ ability to consider complex questions and whole systems in their design solutions, asking questions such as “how big is here?”, “how does this place work?”, and “how might the nature of here evolve?” What sets this program apart is both the BCIT polytechnic approach – providing technology-based solutions in response to industry needs – and the Architectural Science program methodology: to teach a ladder of critical thought, following a deliberate and evolving framework. This scientific process works through progression, analysis and repetition to ingrain sustainable thinking, reinforced in every core course delivered.

terized as follows:

establishing foundations to guide sustainable design decisions. This is pursued through the study of historical and contemporary precedents, building materials and tectonics, and foundational design studio, while developing essential skills in the building science of sustainability. Level 6 leverages these foundations and skills into applications of sustainable design solutions, increasing technical and graphic communication and continuing the development of building science competencies. Entering Level 7, students are prepared to not only apply but evaluate the implications of design strategies and solutions. A laboratory approach is used in building science and design studio, developing iterations to improve process and results while promoting whole-building systems thinking. Bridging from Level 7 to 8, students perform research and analysis to develop a unique socially-driven high-performance building proposal. All core Level 8 courses converge upon the delivery of that comprehensive capstone project, which integrates the complete technology-based skill set developed and revisits each step of the ladder of sustainable design thinking. This closed-loop approach reinforces and refines not only the learning process but the teaching process, which is revisited with each generation of capstone projects. The most recent program innovation is to weave the building science stream fully into Level 8, to ensure that future capstone projects consistently demonstrate leading-edge tools and techniques for high-performance building design. The goal of this Bachelor of Architectural Science program is to produce industry-ready participants in the real world of sustainable thinking and building. Graduates are valued for their analytical and technical skills in the execution of complex design processes, hard earned through ongoing practice and reinforcement. We are pleased to congratulate our graduates and program head on their CaGBC awards, and proud of this program’s role to pursue and promote a broad vision of sustainability - not as a technical or peripheral solution, but as a vital and integral consideration at the core of every design decision.

DIGGING DEEP Unearthing the Truth About Green Roof Growing Media The Green Roof Innovation Testing Laboratory [GRIT Lab] at the University of Toronto, John H. Daniels Faculty of Architecture, Landscape, and Design, is focused on investigating the environmental performance associated with ‘green’ and ‘clean’ technologies such as green roofs, green walls, and green roof integrated photovoltaic arrays. By Hadi El-Shayeb, Liat Margolis, and Jennifer Drake

Green roof technology is widely recognized as a key component of sustainable building design across North America. The wide range of benefits associated with green roofs is captured to varying degrees in the U.S. Green Building Council’s LEED rating system. USGBC acknowledges that not all green roofs are made equal and the extent to which a green roof can help earn credits varies accordingly. The LEED guide offers general design direction, while municipal standards tend to establish specifications that address regional conditions and priorities. Although the City of Toronto is a North American pioneer in green roof design policy, the City’s 2009 Green Roof Bylaw set few locally nuanced performance targets. The Bylaw stipulates that all developments above 2,000 sq. m. [21,528 sq. ft.] must have 20-60% of their roof area installed


with a green roof. Beyond coverage, the Bylaw simply requires that the selected plant species survive for at least 3 years and maintain a minimum of 80% vegetated cover.

1 - Research by the GRIT Lab confirms that green roofs can reduce stormwater runoff significantly. 2 and 3 - Growing media consist of two types: mineral aggregate mix with a low percentage of organic matter [left], and an organic matter blend designed to support vascular plants.

This benchmark is problematic, as it may result in green roofs that fail to deliver the other important benefits widely

Interestingly, the North American industry favourites are the FLL blends. Hill et al. [2016] found a number of growing media manufacturers in Canada advocating for mature wood-based compost with up to 50% initial organic content, which points to a growing interest in the benefits organic materials can offer. “High organic content” refers to a growing medium that contains a minimum of 30% organic content, as measured by loss of ignition [LOI]. LOI is a lab metric commonly used by manufacturers of growing media, that is determined by burning the medium in a furnace. This is quite different from measuring bulk components by volumetric content. For example, a mix containing 30% organic matter [e.g.



compost] and 70% non-organic, matter [.e.g. mineral] content by volume, will have an LOI considerably less than 30%. This is because the compost itself contains only 50-80% combustible material.

The survey by McGlade and Hill [2014] showed a strong trend toward the use of organic material for roofs in southern Ontario, the average among those tested being 53%. This trend may reflect the emphasis that has recently been placed on ecological objectives, such as increased biodiversity, the use of native plants and the attraction of pollinators, as well as the desire to achieve a meadow-like, or naturalized aesthetic.

High organic media also tend to be less dense than mineral alternatives, which makes them ideal for reducing the imposed load, particularly on existing structures, without compromising stormwater retention and plant health. Correlating growing media, plant selection and maintenance practices As discussed by McGlade and Hill, the original objective for the extensive green roof on the Earth Rangers facility in Woodbridge ON, was to provide stormwater retention and cooling for the building. The FLL growing medium originally specified was planted with succulents only. However, over the first six years the vegetation did not mature, and in fact grew sparse. Clearly the initial design did not meet the performance expectations of either the installer or the client. Learning from this mistake, the owners replaced an adjacent green roof with a high organic content growing medium to support a mix of native perennial plant species. When analyzing extensive green roofs 10-years of age or older, the composition of the growing medium, rather than its depth, proved to be the most significant design consideration for robust and biodiverse plant growth. Even green roofs with less than 10cm of growing medium, such as on the roof of the Royal Ontario Museum, successfully sustained a broad range of succulents and herbaceous plants, so long as the organic content was at

The University of British Columbia consistently showcases its interest in building innovation. UBC’s enrollment growth meant that new student housing was needed. Additional housing for over 400 students called for a quick, sustainable and cost effective building solution. The building was completed less than 70 days after the prefabricated panels were delived to the site, with the installation rate averaging two floors per week. Adhering to the province’s “wood first initiative”, Brock Commons is the first mass wood, steel and concrete hybrid project over 14 storeys tall in the world. Due to the upkeep costs of natural wood, Trespa® was introduced as a substitute to eliminate any


SABMag - WINTER 2017/18

Think Trespa

additional life cycle costs while preserving the desired aesthetics. DESIGN

The choice of colours was another factor in selecting the cladding material. As a signature structure on campus, a beautiful and low maintenance facade was mandatory. Trespa® fulfilled the requirements creating a building that will continue to be an architectural gem on campus for many years. In order to house over 400 students, the tower includes 404 beds within 33 four-bedroom suites. Centrally located with stunning campus and ocean views, it is the pinnacle of student housing and was completed in the spring of 2017.


Standing at 53 metres (174 feet) high, Brock Commons is currently the world’s tallest mass timber structure. The entire façade of this student residence is constructed with steel stud framing with exterior sheathing, insulation and Trespa® Meteon® for the rainscreen. The use of modular construction reduced the build schedule by over 10% and improved installation quality using a controlled environment. DURABLE

Trespa’s patented Electron Beam Curing (EBC) process creates the industry’s most colour stable and homogenous phenolic panel. Resistance to weathering, UV

exposure, dirt accumulation, scratches and dents means the panels will look as beautiful today as they will in decades to come. Trespa® helped reduce the façade life cycle costs which would have included cleaning, re-staining or re-painting every 3–5 years. This was essential in meeting budget requirements over the life of the building. SUSTAINABLE

Not only does Trespa® add to the beauty of UBC’s campus, it is also PEFC and FSC certified and made with 70% wood fibres, making it an environmentally responsible product. As part of the rainscreen system, it contributed to the building achieving LEED Gold certification by meeting R-16 thermal resistance. Trespa® helped attain UBC’s vision of a beautiful, long lasting and sustainable building.

“Wood is increasingly recognized as an important, innovative and safe building material choice. This new tall wood building reflects UBC’s leadership in sustainable construction and our commitment to providing our students with more on-campus housing.” Santa J. Ono, UBC President


This remarkable building, the first of its kind in the world, is another shining example of Canadian ingenuity and building innovation. With a large global push for sustainable wood construction, the project was a popular destination for those eager to learn how it was designed and built. Visitors comprised of delegates from around the world including the 2020 Japanese Olympic Committee for construction of Olympic venues and housing. Brock Commons paves the way for additional “wood first initiative” projects across North America and the world.









“What I like about the Natural Bagenda is it does not mimic an actual wood grain. Rather, it is a man-made pattern that evokes the spirit of wood. Trespa is also made with 70% wood fibers, which was a compelling consideration as it aligns with the spirit of Brock Commons’ mass wood structure.” Russell Acton, Principal of Acton Ostry Architects Inc.

SABMag - WINTER 2017/18

The truth is, had we tried to expose the wood, and prove its performance through fire-simulation modelling, the building could not have been built within the tight schedule or the available budget. The research done for this project suggests that an exposed wood structure is more than twice the cost of an encapsulated one. However, the realities go beyond the straightforward comparison of structural costs to include the additional costs of running exposed services, and the kid-gloves handling required on site for any mass wood component that is also to be exposed as a finish material. The time and effort required upfront to achieve successful results also adds to the cost. All this results in a premium few clients would be prepared to pay however committed to sustainability they might be. So common sense suggests that the interests of sustainability would be better served by mass wood buildings that are cost competitive, therefore more attractive and accessible to developers. With this affordable and replicable approach, we would be building far more mass wood buildings, using far more wood and storing far more carbon dioxide than would be achieved with the construction of fewer and more expensive, exposed wood solutions.

In this way, sustainability can be more effectively advanced through the construction of more encapsulated mass wood buildings at a lesser cost. At Brock Commons, we were permitted by Code to expose the wood on the top floor, and to include a mass wood canopy, and we should be realistic in our expectations that, in a building like a student residence, this is really all that is appropriate. Exposing more would be asking for trouble in terms of vandalism and increased maintenance costs due to wear and tear. In countries like Germany, Austria, Switzerland and the United Kingdom, where most of the world’s mass wood buildings are being designed and constructed, it is relatively rare that the wood structure is left exposed, with the exception of a feature wall or ceiling. Frankly, this is what the market seems to want anyway. Most clients and building users don’t want wood exposed everywhere – they prefer white or plain surfaces for the most part. If we accept these realities, exposed wood buildings then become the rare, evocative showpieces they are intended to be, made possible by much higher budgets. Such feature buildings will most likely be limited to taller, image-conscious corpo-


rate buildings and public buildings such as libraries, community centres and possibly academic buildings, where the constant presence of people will provide a significant level of reassurance and security regarding vandalism concerns. The use of exposed wood in such applications will likely be considered well worth the added expense in the long term. In most other building types, we must get past our fixation with philosophical posturing that the ‘beauty’ of exposed mass wood structures must be achieved at all costs, and instead focus on practicality and economy.

This is not to deny the unique visual quality that the strategic use of exposed wood can bring to a building, however, this is not the core concern of the mass market, any more than sustainability is. What they are interested in is the speed, the precision, and the cleanliness of the construction site. We achieved all of this at Brock Commons, and the experience will certainly influence the attitudes of the contractors and subtrades toward future mass wood projects. These changing attitudes will also help to move mass wood technology forward, and so long as the wood option is cost-competitive — the current cost premium will inevitably lessen over time as the industry innovates, evolves and matures — the sustainable attributes of the material will be more widely available and include an environmental bonus of carbon sequestering and use of a renewable resource in the future growth of cities.

INTERVIEW WITH BRIAN EBERLE Brian Eberle, Director of Marketing & Sales at EUROSHIELD® Roofing Products [htttp://www.euroshieldroofing.com/] in Calgary loves old tires since they are the main ingredient in a line of slate and shake roofing styles that can out-perform the real thing.

What’s the ‘elevator pitch’ on the EUROSHIELD® story? G.E.M. Inc. [EUROSHIELD® Roofing Products] was founded in 1999 by local Calgary entrepreneur Henry Kamphuis with the goal of producing the world’s finest rubber roofing shingles using the deluge of used tires ultimately destined for landfill sites. Years of research and development has led to the creation of a unique formula containing approximately 70% tire rubber and 95% recycled content, resulting in the very best synthetic roofing products available on the market today. Approximately 400 [but up to 1,000] rubber tires are diverted and recycled in the production of a single EUROSHIELD® roof for a residential home. Scrap material generated during the
