Testimonials The organization and the set up of this virtual expo were amazing and I think that this first edition was a success. The platform was great at simulating a real Expo hall. A good variety of people visited my booth so that I was able to network with many interesting companies. I loved the sustainable nature of this event: no brochures to print, no booth to build, no travel. Overall an amazing and completely new experience! Congratulations to organizers and we wish you more success at the second edition! Nicholas Varias, Dipl.Arch.,CBCO President Flexsola International Development Corporation For me it was exciting to meet and exchange contact information with so many people from the green building network. High quality exhibitors were easily reached directly from my PC. Walking around the expo was easy and fun. The webinars were extremely informative and easy to attend just in one click without stressing over travelling problems. A smart way of doing business! A great experience for all involved and I’m looking forward to the next such event. Thumbs up!! Virgiliu Petre OAA LEED AP MBA DEA M.Arch. Principal, Eco Revival Consulting

rade shows are an expensive but necessary part of doing business. With the cost of your booth rental and all of that extra promotion you could easily spend up to $100,000 per show. I’ve seen a lot of large stands with major corporates with overall bills approaching the seven-figure mark. And in many ways, beyond the financial implications, a virtual show has much more going for it. A physical trade show can be a hassle for a large corporation and a major logistical nightmare for small and medium players. At a physical convention, hundreds of vendors and thousands of attendees are jammed into a cramped, noisy space. It’s really hard to know who’s worth talking to. Often, the “little guy” gets dwarfed by the “big boys,” armed with substantial war chests, premium advertising and booth space, as well as high-profile keynote presentation exposure. Now, thanks to computer technology, the playing field is level. Imagine a trade show with no costs for transportation, shipping, hotels, hospitality, or booths,

Shawn Marsh, President of Timberworx Custom Homes

Timberworx lauded for designing (and building) Canada’s first certified luxury net zero home

imberworx Custom Homes has achieved the kind of industry recognition that is impossible to top. It’s an extremely impressive feat – gaining fame and recognition as the visionary builder responsible for Canada’s first certified luxury net zero home. “There were a lot of ‘firsts’ with this home,” says Shawn Marsh, President of Timberworx. “But we look at those as stepping stones to the future, where we will be building ultra high performance homes that are not only societally responsible, but also the right thing to do.” A net-zero energy (NZE) home is designed and built to reduce household energy needs to a minimum and includes on-site renewable energy systems that enable the home to produce at least as much energy as it consumes on a yearly basis. In respect to the Timberworx luxury net zero home at 19 Lambeth Lane in Puslinch, Ontario, the design focused on being ultra high performance without compromising the appearance or curb appeal. Situated within the Heritage Lake Estates, a picturesque community of estate style homes, it features the use of Canada’s first Tesla spring 2018

Powerwall 2 battery backup storage systems for the solar energy produced, as well as energy efficient windows, glass curtain walls and energy-saving heat pumps. Just imagine those features, but not in a low-budget, space-

saving home; instead, envision them in a luxurious, 9,200 square feet of living space. “What we always do at Timberworx is talk to the clients first and ask them our favourite question – ‘why not?’” says Marsh.

“Why should we sacrifice a glass area, for example. Couldn’t we engineer the windows to a high standard?” In this case, that meant their engineering

team came up to a new custom design for 19-foot-tall curtain walls of glass in the fourseasons’ room. Timberworx also challenged its HVAC team to deliver a custom system needed

to achieve its net-zero goals. “We were able to get all our trades on board and they were excited to be part of the project,” Marsh says.

“It definitely required extra effort on everyone’s behalf, but the results of that joint effort are evident in the incredible air tightness of the building.

With 0.82 air changes per hour for a 9,200 square foot home with walkout and multi-level ceiling heights that ranged from 12-20 feet, the results speak for themselves. There’s

amazing performance, comfort and, above all, planet stewardship. “We wanted to make the home a model from which to sell,” Marsh continues.

“We said ‘let’s build it, monitor it, learn from it, perfect it … then we can implement what we have learned into our work moving ahead.” To that end, Marsh says Timberworx has engaged its energy advisory companies - Building Knowledge Canada and Bowser Technical – to provide regular training for both its staff and trades on best practices in the rapidly evolving field of ultra high-performance homes. All lighting in the home is controlled by a full Lutron HomeWorks automation system, provided by Station Earth, a home technologies company from Fergus, Ontario. This allows the owner to set specific timers and schedules

to maximize energy efficiency, plus there are convenient lighting keypads throughout the house which offer control of the lighting scenes in individual rooms. The house can also run autonomously while in ‘away’ mode. The shades will open and close automatically to harvest or reject sunlight depending on the time of year and weather the house needs heat or cooling. It does this through the control system that integrates HVAC, lighting and shading into one cohesive dashboard. All of these features can also be controlled remotely. So if the owner is away they can view and manage all electronic systems in the house.

The automatic shades, by the way, provide increased energy efficiency by reducing solar gain in the summer without sacrificing the beautiful views. For Marsh and Timberworx, it was important to consider the overall ‘look’ of their net zero home, something they factor into every project. “We don’t want anyone to walk past one this home and say ‘wow, look at that environmentally-sustainable home,’” adds Marsh. “For instance, we took great care to design a commercial-style flat roof complete with parapet walls to hide the solar array. (For the record, this model of home faces north, but the solar array faces south). This had the added benefit of allowing us to turn the array however we needed in order to maximize electrical output instead of being hampered by the orientation of the building.”

Shawn Marsh, President of Timberworx Custom Homes, has started a two-year term on the Net Zero Energy Housing Council (NZC) with the Canadian Home Builders’ Association (CHBA). “I want to be sure we are up to date on the latest technologies,” says Marsh. “I am also in my fifth year on the OHBA Technical Committee where we review upcoming code changes, new terminology and listen to industry progress courses on best practices.” At Timberworx, Energy Star has always been the base building standard. And in 2018, net zero ready will be the new base standard for the company. The next two sites for Timberworx – Heritage Lake Estates Phase II and Fox Run Phase II (partnered with Sloot Construction) – will be among North America’s first net zero estate subdivisions. spring 2018

Winner of wood design award an owner-driven, intergenerational home

The project in Ancaster, Ontario, has won the WoodWorks 2017 residential wood design award. It constructs a scenario for living that allows for autonomy while mutually benefitting from proximity. It confirms that sustainable systems and designing for the elderly are not exclusive from modern expression and exquisite details. As the family changes so can the family home.

dicular to each other, creating a landscaped courtyard setback from the street, and stack at the corner. Ancaster Creek and its associated floodplain traverse the property. This site is one of 596 private properties that accommodate forest, wetland, meadow, and aquatic habitat in this protected area. The house is located at the back of the property in close proximity to the creek, while respecting the meander line to avoid the floodplain and erosion hazards of the watercourse. The landscape moves through the house, creating a natural context and denying the collection of McMansions that have been developed around the site and attempt to contextualize it as suburban instead of as connected to the land. The parentsâ&#x20AC;&#x2122; suite occupies the ground floor with the living and dining space anchor-

ing the view. The suite is laid out as a single floor accessible apartment with added features to accommodate the specific challenges facing the aging parents. Among them, well-located drains and a master power switch mitigate issues that have come with memory loss: a sink left running, or an oven left on. A second bedroom and bathroom are adjacent, but separate, for a live-in relative or nurse. Running parallel to the creek is the main residence. The kitchen anchors the south end of the house. Set in a double height volume, the 20-foot-tall pyramidal ceiling creates an expansive space that opens to the creek, the courtyard, and above to the sky. Back-painted glass and polished Calacatta slabs are meticulously detailed to reflect the surrounding landscape and contrast the heavy, flat-sawn solid oak island with a faceted base.

Second is the envelope: High-performance glazing systems, including triple-pane woodframe windows with an average Uw (heat loss rating) of .77, anchor the highly insulated envelope. Radiant floor heating can then be used sparingly and only to compliment a high efficiency furnace. Finally, a 37 module 9.8 kW Canadian made solar array was installed across two of the flat roofs, offsetting energy

The dining room occupies a glazed link pinched between the landscape that flows from the creek, through the courtyard, and to the front of the house. The living room, with a honed travertine fireplace and oak wall rendered in the form of the exterior cladding, extends under the cantilever in the summer months, doubling in size. These social spaces are shared by the extended family. A connected hallway that is easy to navigate for the parents leads around a softened corner and draws the family together. The grand gesture of a wood-clad spiral staircase connects the living room to the second floor master suite, creating a unique moment in the otherwise orthogonal room and celebrating the connection between floors. The curvature opens as it rises and becomes the ceiling of the adjacent wing, creating a pinwheeling effect that leads to the parentsâ&#x20AC;&#x2122; suite.

The small second floor acts as a private suite. A lounge with concealed bar extends from the large landing, a custom oak library painted a soft blue provides an office space, a light-filled cantilevered bedroom reaches out into the best views of the creek and a serene bathroom clad in gray marble tiles sits across a linear walk-in closet.

asia Hotel Downtown, designed by Singapore-based WOHA Architects, presents a radically different face to the world than its glass neighbours in that city’s central business district (CBD).

The structure incorporates 25 species of creeper plants into its permeable aluminum façade, giving the high-rise a character that is both unique and indicative of the architects’ conception of design for the high-density, yet green, city. WOHA’s design for Oasia Hotel Downtown moves beyond vague notions of “sustainability” by fundamentally embracing living systems into a mixed-use program—one that grows, rather than exhausts, a city’s resources. spring 2018

While buildings most often stand in opposition to nature, replacing green with grey, WOHA’s work proposes that even our highestdensity-built works can amplify living greenery within urban space. Oasia Hotel Downtown actively contributes a lush, living ecosystem to the city, from footprint to skyline, by producing over 1,000 per cent of the greenery found on the site prior to its construction. Over time, the tower’s open terraces, sky gardens and blossoming façade will evolve into a lush and permeable envelope. With the Oasia Hotel Downtown structure divided into both hotel and office uses, there was a great need for a circulation plan that

Green Building + Architecture

could support varied uses and allow for individualized open spaces. WOHA’s plan of distributing necessary elevator and building service cores to the four corners of the building allows for generous open spaces on the sixth, 12th, 21st and 27th floors. As WOHA principal architects Richard Hassell and Wong Mun Summ are keen to point out, this distribution scheme allows the rare pleasure of standing in the center of an upper sky terrace and taking in a 360-degree view. Singapore’s newest tower breathes life into the upper reaches of the CBD skyline. This architectural prototype, with its naturally

ventilated shared spaces and growing material palette, is a novel architectural experience, whether from afar or from within. Moreover, in keeping with the Singaporean firm’s extensive experience and expansive repertoire, Oasia Hotel Downtown embodies WOHA’s vision of high-rise, high-amenity architecture that responds to the complex conditions of megacities and the broader Global South. As a prototype of land use intensification for the urban tropics, this tropical “living tower” offers an alternative image to the sleek technology of the genre.

Closely overlooked by surrounding towers, the tower carves out its own internal spaces and dynamic views instead of relying on external vistas for visual interest. Each sky garden is treated as an urban scale veranda, sheltered at high level by the preceding sky garden and open sided for formal and visual transparency. The openness also allows breezes to pass through the building for good cross-ventilation. In this way, the public areas become functional, comfortable, tropical spaces with greenery, natural light and fresh air instead of enclosed, internalised air-conditioned spaces. Landscaping is used extensively as an architectural surface treatment and forms a major part of the development’s material palette both internally and externally. Achieving an overall Green Plot Ratio of 1,100 per cent, the tower is conceived as a haven for birds and animals, reintroducing biodiversity into the city. This quantum of green is an exciting number, as it effectively compensates for the lack of green in 10 surrounding buildings. The tower’s red aluminium mesh cladding is designed as a backdrop that reveals itself in between 21 different species of creepers, with colourful flowers interspersed among green leaves, providing food for the birds and insects. The creepers will form a mosaic with each type taking over its most suitable conditions of light, shade and wind. Instead of a flat roof, the skyscraper is crowned with a tropical bower; floral, diverse, soft and alive.

Active House: a model of sustainable suburban development By Sarah Hicks Communications Cordinator Ontario WoodWORKS!

ctive House has a vision for the future. It’s one where buildings create healthier and more comfortable lives for occupants, without negative impact

spring 2018

on the climate, moving us towards a cleaner, healthier, and safer world. The Active House label is a world-wide quality stamp for comfortable and sustainable buildings. Its metrics emphasize energy efficiency, low environmental impact, and superior occupant comfort. Active House – Centennial Park is a model for modern, suburban development that sets

a new standard of sustainable design for the thousands of new homes built in Canada every year. Wood and panelized wood construction were central in achieving the home’s high level of performance, so the project was a natural standout in the Environmental Award category at the Ontario Wood WORKS! Wood Design Awards. Green Building + Architecture

The system employs an integrated 3-ply exterior sheathing material (rigid Insulation, OSB sheathing and house wrap all in one). Fabrication in a factory setting, using computer generated cuts, optimized material use resulting in minimal waste.

Marianne Berube, Executive Director of the Ontario Wood WORKS! program that hosts the awards, remarked on the use of wood in contemporary construction. “Today’s wood products and systems are technologically advanced. Project teams are using these highperformance building materials in exciting ways, actively and imaginatively exploring wood’s expanding potential. Design professionals who understand the need for sustainable development are increasingly specifying wood products for innovative, environmentally responsible construction.”

exterior LED lighting systems, triple-glazing, low-flow water fixtures, low-VOC finishes and energy-performance monitoring systems complement the primary design strategy of

maximizing opportunities for natural daylight and ventilation, ultimately achieving a greater sense of health and well-being for the occupants.

Great Gulf’s H+ME Technology system — an advanced indoor automated manufacturing plant that allows roof, wall and floor assemblies to be built as integrated panels in a controlled environment — was essential to the project’s success. The H+ME Technology facility is supported by construction visualization, prototyping and fabricating technologies that reduce environmental waste and increase energy performance through the manufacture of tight-fitting building components. The system even provides the opportunity to build full-scale mock-ups to verify a project’s energy efficiency. Wood’s environmental credentials and superior thermal comfort over other materials made it the obvious choice on this project. Its low embodied-energy and ability to capture and store atmospheric carbon is unlike any other building product – making it a natural choice for building sustainable, comfortable, high-performance homes. The house occupies a modest footprint, but enjoys a greater feeling of expansiveness from the amount of natural daylight filtering in through the generous and strategically placed windows and skylights. This strategy also increases the potential for cross-breezes which naturally ventilate the house while decreasing reliance on air conditioning. An open-plan configuration with doubleheight spaces connects all areas of the house without sacrificing privacy, removing visual barriers while creating a greater sense of engagement between family members. Consequently, the home feels far more spacious than its 2,900 square feet. Light and nature is brought further into the house through the provision of a small C-shaped courtyard, with views from all three sides outside to the surrounding flora and fauna.

Active House – Centennial Park is a prefabricated, panelized wood structure. The wall, floor and roof panels were factory built, flat packed, and brought by truck to the site for assembly. This efficient construction strategy reduced both construction waste and the duration of onsite construction; the frame of the entire house was erected in just a few days. The innovative structural wood roof and wall system has an integrated air barrier that streamlined the weatherization process and vastly simplified and accelerated the assembly of the exterior walls.

It will guide the way towards more sustainable and more legacy-driven sporting competitions, opening up hosting opportunities to countries all over the world. The stadium is aiming to achieve a fourstar Global Sustainability Assessment System

(GSAS) certification. People who live close to the stadium site will enjoy a verdant waterfront development that will occupy the site once the stadium has gone. Work will begin soon after the final whistle brings the venue’s World Cup quarter-

final match and the stadium’s tournament duty to an end. As soccer fans make their way to Ras Abu Aboud Stadium, enjoying stunning views of Doha’s skyscrapers from across the bay, they will marvel at a soccer stadium unlike any other.

World Cup soccer stadium features transportable, socially-responsible design

panish firm Fenwick Iribarren Architects (FIA), led by architects Mark Fenwick and Javier Iribarren, has conceived the first transportable and reusable stadium in the world, to be unveiled at the Qatar 2022 FIFA World Cup.

The stadium’s design is unique. Its structure is based on shipping containers, which can be easily assembled or disassembled as required. The main objective is to create a sociallyresponsible stadium based on following concepts: modularity, movability, legacy, functionality and iconic image. Using adapted shipping containers as 24 Green Building + Architecture

building blocks cuts down on the amount of building materials required, creating less waste and reducing the stadium’s carbon footprint. Fenwick assures that “we are confident that this innovative and sustainable concept will serve as an inspiration for other architects from all over the world; and will allow for the creation of aesthetically pleasing spaces to serve as a legacy for future projects.” Constructed using shipping containers, removable seats and other modular ‘building blocks,’ not only will this innovative, 40.000-seat venue have a remarkable design, but it will be completely dismantled and repur-

posed following the tournament. “This venue offers the perfect legacy, capable of being reassembled in a new location in its entirety or built into numerous small sports and cultural venues,” said Hassan alThawadi, secretary-general of Qatar’s World Cup organizing committee. “All of this in a stadium that delivers the atmosphere fans expect at a World Cup and which we will build in a more sustainable way than ever before.” In its short lifetime, Ras Abu Aboud Stadium will create an innovative blueprint that will give global stadium developers and tournament planners a fine example to follow. spring 2018

SINGAPORE TOWER blends nature and architecture with high-tech

The result will be a distinctive, boldly colourful and thoroughly modern arena that will almost look like it is made from building blocks. The design uses prefabricated and modular elements. This approach reduces the waste generated during production of stadium components and the waste created on site during construction. The use of modular elements also reduces the venue’s construction duration.

Green Building + Architecture

The venue’s temporary nature and clever modular design will mean that fewer building materials will be required than in traditional stadium building, helping to keep construction costs down. And with other projects reusing the seats, roof and other components of the arena, parts of the venue will be utilised for years and even decades to come. Minimizing construction costs and ensuring regular future use are the key ingredients in

making a new stadium and sporting megaevents sustainable.

The tower, one of the tallest in Singapore, will redefine and elevate workplace and living standards while adding an elegant new landmark to the Singapore skyline.

The design concept will result in the swift, cost-efficient construction of a stunning arena, which will have an elegant curved square form. The enclosed shape of the stadium will ensure a memorable atmosphere for both fans and players.

Located in the heart of Singapore’s financial district, the new 93,000 m2, tech-integrated and verdurous

skyscraper which includes the ‘office of the future’, a serviced residence and retail components, transforms the site of a former car park complex built in the 1980s. The tower is set to make a distinctive mark on the Singapore skyline: the building’s exterior facade consists of vertical elements that are pulled apart to allow glimpses into the green oases blooming from the base, core and rooftop.

A dynamic interplay of orthogonal lines and lush greenery presents itself in the contrasting textures of steel and glass, interweaved with tropical vegetation. At the ground floor, visitors will be met by a public rainforest plaza and park. Meandering garden paths and covered passages create natural entryways into the City Room, a 19m-high generous open space at the foot of the tower. The first eight floors of the tower are dedi-

cated to the serviced residence including a wide range of facilities such as a swimming pool, jacuzzi, jogging track, gymnasium, social kitchen, residents’ lounge and barbeque pits. The top 29 floors of the tower offer premium office spaces with panoramic views to the Singapore River and Marina Bay. At the core of the building between the hardscapes of the offices and residences are four connected levels of organic softscape, called

the Green Oasis – a mesmerizing 30m open-air garden for work, casual strolls, relaxation, exercise and events. Four interconnected levels of the tower, at the 100-metre point, will be dedicated to a 30-metre high vertical park, with a covered spiral stairway rising through the centre. This tropical garden will also feature a jungle gym, cocoons suspended in the treetops, “sky hammocks” and a cafe.

BUILDING WITH WOOD

“Working in nature will be as essential to the experience of the building as the most advanced digital technologies, offering us a glimpse of tomorrow’s offices,” said Carlo Ratti, CRA’s founding partner. Tech-wise, the Singapore Tower is due to have sensors, Internet of Things-enabled devices and artificial intelligence capabilities “scattered throughout” to allow tenants to “fully customise” the skyscraper. “The upcoming integrated development will set a new benchmark for workspaces of the future as we harness the best-in-class design, engineering and smart technologies to empower occupants with new levels of flexibility and mobility,” said CapitaLand president and

CEO Lim Ming Yan. While the upper 29 floors will be office spaces, a sky terrace on the rooftop is set to feature more cascading greenery, a restaurant, and what the developers claim will be Singapore’s “highest urban farm”. “The upcoming development will define the possibilities for workspaces of tomorrow,” says the firm, which has some experience in such things. “With facial recognition technology, executives will enjoy seamless and secure access to their offices with a mere glance at a camera. Imagine cycling to work via the park connector, storing your bicycle in one of the available lots, freshening up at the end-of-trip

facilities and booking a meeting room via an all-in-one lifestyle app before you even arrive at the office. With a simple touch on your mobile device, adjust your ambient thermal comfort or lighting to customize your workspace preferences. To further optimize user experiences and business operations, sensors, Internet of Things (IoT) and artificial intelligence (AI) technology will be deployed throughout the development. Robots and digital technologies will supplement cleaning and security services, enhancing productivity and efficiency in building maintenance.” The two firms expect to complete 88 Market Street by 2021.

Climate and Cost Benefits of Wood Building Systems By Peter Moonen Canadian Wood Council

orldwide, the building sector contributes up to 30% of global annual greenhouse gas (GHG) emissions, which are a significant cause of climate change. The UN Environment Programme estimates that these emissions could double in the next 20 years if nothing is done. In Canada,

the building sector accounts for about 12% of total GHG emissions – only the oil and gas and the transportation sectors have higher emissions. Concerns about climate change are encouraging decarbonization of the building sector, including the use of construction materials responsible for fewer carbon dioxide (CO2) emissions and improvements in operational performance over the life cycle of buildings. Wood and forests can make a contribution to

both avoidance and mitigation of climate change in four major ways – Sustainable Forestry, Carbon Sink, Carbon Sequestration and through Substitution of emissions-intensive materials -- the 4-‘S’ solution. Forests and Climate Change The Intergovernmental Panel on Climate Change believes that a sustainable forest management strategy aimed at maintaining or increasing forest carbon stocks while producing and using timber in longer lasting applications can generate the largest sustained benefit to mitigate climate change. Carbon pools, or sinks, are reservoirs that can store or release carbon. The forest represents one carbon sink, storing biogenic carbon in soils and trees. The carbon remains stored until the trees die or decay. When a tree is cut, 40% to 60% of the biogenic carbon remains in the forest; the rest is removed as logs and much of it is transferred to the wood products carbon pool within the built environment. Wood products continue to store this biogenic carbon, often for decades in the case of wood buildings, delaying the release of CO2 emissions. When the forest is regenerated, it begins to store carbon again, leading to a net overall gain in the total carbon pool. Once they reach the end of their life cycle, wood products are often recycled or recovered to generate renewable energy, displacing the use of fossil fuels. A forest is a natural system that is considered carbon neutral as long as it is managed sustainably, which means it must be reforested after harvest and not converted to other land uses, including non-native forest types. Since Canada’s forests are mostly held by government bodies, Canada has some of the strictest forest management regulations in the world, requiring successful regeneration after public forests are harvested. Canada is also a world leader in voluntary third-party forest certification, having more certified forests than USA, Russia, Australia and Sweden – combined - adding further assurance of sustainable forest management. Advantages of wood building systems A building that is a good choice for the environment can often address broader social needs and offer higher economic value. People prefer to live, work, study and play in a well-designed and visually appealing building – and this is more likely to extend its life and make it a better investment. It also sends a signal that the building owner is environmentally responsible and cares about the well-being of occupants. A study by FPInnovations found that people are happier, healthier and more productive when they are connected to nature. The use of natural elements in a built environment – including daylight, plants, nature soundscapes and natural materials such as wood – creates a more positive space for any activity. It reduces stress and improves productivity and concentration. Green Building + Architecture

In health care facilities, the presence of natural materials is associated with faster recovery times, lower pain perception and positive dispositions. This benefits not only the patients, but visitors, health professionals and health care budgets as well. A comfortable indoor environment affects the health and well-being of occupants. Good interior air quality reduces exposure to pollutants and provides moderated humidity levels. Bare wood is hypoallergenic. Bare wood can also help modulate indoor humidity by absorbing or releasing moisture to maintain equilibrium with the indoor environment. Wood is an excellent choice when acoustics are a design consideration. Its unique cellular structure can help to dampen sound vibrations. This is especially important in home and office environments where unwanted noise can cause stress or interfere with activities. Wood is often the material of choice where quality acoustics are important, such as concert halls and auditoriums. The most energy-efficient buildings are made with materials that resist heat flow, and are constructed with accuracy to make the best use of insulation and air barriers. Wood has millions of tiny air pockets, making it a natural thermal insulator. It loses less heat through conduction than other building materials. Wood-frame construction techniques support a wide range of insulation options and low-energy design solutions. Once a building has reached the end of its service life, the potential environmental impact of its disposal must be considered. Designing for disassembly and adaptability can be critical in end-of-life scenarios that allow for recovery of materials and avoidance of disposal to landfill. End-of-life alternatives such as reuse, recycling and energy recovery often lead to lower GHG emissions. Many wood products are often reused, recycled or recovered for energy.

Trees absorb CO2, store carbon and provide wood products that can replace other more GHGintensive materials. Learn more about the carbon benefits of wood buildings by visiting the Carbon Calculator tool on the Canadian Wood Council’s website (http://cwc.ca/carboncalculator/). This tool will help you to learn about how much time is needed for Canadian and U.S. forests to grow a particular volume of wood along with the associated carbon stored. In general, bio-based products like wood that are naturally grown with help from the sun have lower embodied emissions. Costing One of the underline considerations common in the planning and execution of any project is cost. However, the notion of cost considerations span beyond dollars and cents. There are many elements to consider as part of a cost comparison when evaluating a project or building material versus another. The term ‘cost’ can be perceived interchangeably with ‘value’. When we think about the value that wood buildings bring in terms of social and economic benefits, the examples are vast. A building that is a good choice for the environment can often address broader social needs. People prefer to live, work, study and play in well-designed and visually appealing buildings. Concerns about climate change are encouraging the use of construction materials responsible for fewer carbon dioxide emissions and improvements to the overall operational performance of buildings. Trees absorb carbon dioxide, and the carbon is stored in wood products. When used in construction, wood products replace more GHG-intensive materials. Cost is also dependent on material availability. Canada has about 40% of the world’s certified forests. As such, wood is vastly abundant and readily available to many communities throughout the country. Most communities often rely economi-

cally on the wood product sector for employment and have an abundance of qualified tradespeople with wood product and installation experience. These factors contribute to minimized construction times, ultimately minimizing overhead costs for construction. In the wake of advanced technologies, wood prefabrication is largely gaining in popularity. The accuracy of prefabrication helps to speed up the construction process, resulting in reduced costs, as well ensuring greater accuracy of assemblies resulting in improved building enclosures. Whether prefabrication is used for a specific element of a project such as the walls, or for the entire project (modular construction), wood prefabrication often takes place offsite and in an indoor environment – negating construction delays due to external weather elements, improving worker safety, reducing waste and allowing a more comfortable work environment. Wood products are also lighter and easier to work with, providing the potential for lower construction costs, such as reduced size of foundation substructures and tight tolerances of manufactured and preassembled components. Brock Commons Tallwood House is an 18-storey wood hybrid student residence at the University of British Columbia. The structure was completed less than 70 days after the prefabricated components were delivered to the site. A short time lapse video is posted on YouTube. Wood buildings deliver higher economic benefits because they can be designed to be flexible and adaptable. Buildings are sometimes demolished before they reach their expected lifespan because of changing land values and user needs. Seldom are buildings - of ANY material - torn down due to structural issues. Construction using wood products can extend the life of a structure by making it easier to adapt to changing needs. When it comes to cost comparisons, two things are imperative; that similar data is being compared (apples-to-apples), and that additional factors outside of nominal value are considered. Atlantic Wood WORKS! published a 3rd party mid-rise cost comparison study that analyzed four different building types of equal structure and architectural design to identify cost discrepancies associated with each one. The building types evaluated were: 5 Storeys of Wood + 1 podium of Concrete 6 Storeys of Steel 6 Storeys of Concrete 6 Storeys of Wood Visit Atlantic Wood WORKS!’s website to view the results www.atlanticwoodworks.ca
