As I write, Earth Day 2022 is fast approaching and the Trudeau government is about to introduce it’s 2030 Emissions Reduction Plan. This is the 11th in a series of federal government initiatives that began in 1988, all of which have set targets and all of which have failed to meet them. We have not played our part in this global effort and the price of procrastination is apparent. One effective way of representing the situation is to look at the retreat of Earth Overshoot Day.

Earth Overshoot Day was first calculated in 1970, and marks the date when humanity's demand for ecological resources and services in a given year exceeds what the Earth can regenerate in that same year. The deficit represents the irrecoverable liquidation of stocks of ecological resources and the irreversible accumulation of waste, primarily carbon dioxide in the atmosphere.

An Earth Overshoot Day of December 31 would mean we are living within the ecological boundaries of the planet. In 1970, Earth Overshoot Day was calculated as December 30, meaning resource depletion and regeneration was happening at a (very nearly) sustainable rate. However, by 1995, the same year as the first Conference of the Parties (COP) meeting, Earth Overshoot Day had retreated to October 5. This meant that resource depletion was happening at 1.3 times the sustainable rate.

With the sole exception of 2020 (where human activity of all kinds was constrained by the COVID lockdowns) earth Overshoot Day has continued its retreat. In 2021, and preceding COP 26 by a few months, it came on July 29. This meant that resource depletion was at almost 1.75 times the sustainable rate.

These figures make it clear we must move immediately from siloed and linear approaches to problem solving, to holistic and integrated ones.

Whereas in the past, technology has often been the tool by which the ignorant and uncaring have amplified environmental destruction; it must now be applied to systems-based solutions that make ecological regeneration their highest priority.

Rather than discounting the consequences for future generations, this concern must be central to all our accounting. Our repeated failure to meet our own declared emissions reduction targets has undermined the value of optimism, with many now investing in resignation and despair. There will no doubt be announcements of shiny new sector-specific five-year plans, but we must also look for less volatile and more broadly-based long-term investments to ensure the future well-being of the planet.

These investments must include a restructuring of our education system; underpinning our current STEM-focused programs with a foundation in ecological literacy. With this, we could guarantee that our grandchildren at least would be equipped to inherit the Earth. The challenge for this generation is to ensure there is an Earth left for them to inherit.

VIEWPOINT

DOWEL LAMINATED TIMBER: a step towards circularity in construction

By Sigi Liebmann Wood is widely promoted as a renewable and environmentally responsible material, based on the third-party certification of sustainable forest management (SFM) practices. While this can be successfully argued at the scale of the forest, until now, the argument has not applied equally at the scale of the building.

Crossed DLT in thicknesses up to 30cm.

All durable wood products will store the carbon they have sequestered while part of a living tree, until destroyed by decay or fire at the end of their service life. However, this remains a cradle to grave evaluation that fails to consider the potential for reclamation and repurposing of the product, the GHG emissions associated with manufacture, and the potential environmental and health impacts of any adhesives used.

As mass timber fabricators, we believe that solid wood is the best material to build with from an ethical standpoint, and that using natural timber, as uncontaminated as possible, is the most sustainable approach to take for the planet and for future generations. This is why we chose to manufacture 100% wood, no-glue dowel laminated timber (DLT), a product that is 100% recyclable, reusable and does not produce contaminated waste.

DLT is a relatively new arrival in Canada, although it has been available in Europe for more than 20 years. To produce DLT, layers of dimension lumber are assembled face to face. A hole is drilled through the entire assembly and a wooden dowel is inserted to hold it all together. No glue, no nails, just the wooden dowel.

The wood boards have a moisture content of 10-15%, while the dowels are bone dry. As soon as the dowels are installed and in contact with the surrounding wood, they will absorb the moisture from the boards and expand. This forms a mechanical connection that is incredibly strong.

This type of assembly results in ‘stacked’ DLT panels, so called because ‘stacked’ is a direct translation of the German term ‘Brettstapel’. The surface appearance can be flat or fluted – the latter when 2x4 and 2x6 material is alternated.

In addition to stacked DLT panels there can be crossed DLT panels, a more environmentally responsible product than glue-bonded, cross laminated timber (CLT).

In ‘crossed’ DLT, the large sized panels are manufactured by assembling multiple layers of lumber on top of one another, each layer being at different angles to the one below, and pegging them together with hardwood dowels. DLT need not be glued. Windows and doors are left open as the panel is laid up, rather than being cut out from a finished solid panel. This process minimizes the amount of ‘waste’ material produced.

Building a Better World with Entuitive’s Sustainable Performance Group There’s a strong push by government and society for sustainable solutions across Canada. At Entuitive, we recognize this and are committed to helping our clients develop sustainable solutions in the areas of energy, carbon, and sustainable buildings that work for all stakeholders.

Entuitive offers a broad suite of energy modelling, auditing, and retrofitting services spanning the full asset lifecycle to our clients, from design through to operation and building renewal.

“Often lost in the sea of mandates, standards, certifications, and incentive programs is that there really is only one target for energy performance that we need to achieve – zero emissions. In the coming decades we need to build, retrofit, and replace our existing building stock to transform it into one with a neutral GHG impact. Achieving this will mean creating project designs with an eye to optimizing building performance so that both capital and operational costs are manageable. We work with our clients to be sure that performance targets are achieved in a manner that ensures long term value for all stakeholders. It is truly a generational undertaking,” said Tristan Truyens, Associate and Building Performance Analysis Lead.

Our commitment to sustainable performance has led us to ensure that we’re offering a comprehensive suite of carbon responsible building services to our clients. Our aim is to deliver environmentally sound, highperforming buildings and infrastructure that work for us and for future

Building for today, with tomorrow in mind!

In 2018, Local 144 undertook the construction of a new administrative center and a training center for pipe fitters and pipe welders in Quebec.

This project, funded almost entirely by workers in the pipe trades, had several objectives.

First, we wanted to give our union members access to a state-of-the-art training facility. We also wanted to erect a building that was inspired by the notions of sustainable development. This desire has resulted in the installation of photovoltaic panels, a geothermal system, the recovery of wastewater, the optimization of the use of natural light and, high-performance materials. Pipes and plumbing of this building is a showcase of the know-how of the members of Local 144.

We chose the location of this center in an industrial district in the Montreal region where our union members worked a lot. This is an area that needs revitalization. By settling there, we show our attachment to this community.

Efforts rewarded The USGBC certified our project LEED v4 Platinum; it is the first industrial building to obtain such certification in Canada.

Our building also won two honors at the GRANDS PRIX DU DESIGN – 14th edition in the architecture discipline in the categories: • Special Award / Architecture + Climate Change : Bronze Winner • Commercial Building/Mixed-Use Building : Gold Winne Our pride Today, our members enjoy a modern environment.

New courses are taking place there. They improve the competence of pipe fitters and pipe welders.

We feel that we are leaving a lasting place for generations to come.

Construire pour aujourd’hui, mais aussi pour demain !

En 2018, le Local 144 entreprenait la construction d’un nouveau centre administratif et d’un centre de formation pour les tuyauteurs et les soudeurs en tuyauterie du Québec. Ce projet, financé dans sa quasi-totalité par les travailleuses et les travailleurs des métiers de la tuyauterie, poursuivait plusieurs objectifs.

D’abord, nous désirions permettre à nos syndiqués d’avoir accès à un lieu de perfectionnement à la fine pointe de la technologie. Nous souhaitions également ériger un édifice qui s’inspirait des notions de développement durable. Cette volonté s’est traduite par l’installation de panneaux photovoltaïques, d’un système de géothermie, de la récupération des eaux usées, de l’optimisation de l’utilisation de la lumière naturelle, de matériaux performants… Au niveau de la tuyauterie et de la plomberie, cette bâtisse se veut une vitrine du savoir-faire des membres du Local 144.

Nous avons choisi l’emplacement dans un quartier industriel de la région de Montréal où nos syndiqués ont beaucoup travaillé. Il s’agit d’un secteur qui a besoin de revitalisation. En nous y installant, nous montrons notre attachement à cette communauté.

Des efforts récompensés Notre projet a reçu une certification LEED v4 Platine du USGBC ; il s’agit du premier édifice industriel à obtenir une telle homologation au Canada.

De même, notre bâtiment a remporté deux honneurs lors des GRANDS PRIX DU DESIGN — 14e édition • Catégorie : Prix spéciaux/Architecture + Changement climatique : Lauréat Bronze • Catégorie : Bâtiment commercial/Immeuble à usage mixte : Lauréat Or Une fierté Aujourd’hui, nos membres profitent d’un environnement moderne.

De nouvelles formations s’y déroulent. Elles améliorent la compétence des tuyauteurs et soudeurs en tuyauterie. Nous avons le sentiment que nous léguons un lieu durable aux générations qui nous succéderont.

THE BARRETT CENTRE FOR TECHNOLOGY INNOVATION (HUMBER COLLEGE) The Barrett Centre for Technology Innovation (Barrett CTI) received LEED-Platinum certification in April 2021. The 93,000 square-foot facility was created to spearhead a new model of education, one that omits traditional classrooms for cuttingedge technology zones, interactive demonstration areas, and open-concept gathering spaces. The dynamic Barrett CTI is central among Humber’s campuses, creating a new community hub for students, staff, faculty, industry partners and community members to gather, create and innovate.

Sustainability was an integral part of the design and construction of the Barrett CTI. The facility prioritized passive strategies and extensive energy conservation measures, including high-performance building envelope, natural ventilation to supplement mechanical cooling and a 700 KW-DC solar installation on an adjacent building resulting in net-zero energy. The building boasts floor-to-ceiling windows in the atrium, illuminating the spectacular space with an abundance of natural light and views of the surrounding community while maintaining an average window to wall ratio of less than 40 per cent. Using a conservefirst approach, the building was designed to operate with an annual energy use intensity (EUI) of less than 100kWh/m2. The Barrett CTI is also designed to integrate with Humber’s low carbon District Energy System, which will further reduce EUI and greenhouse gas (GHG) emissions upon completion.

The Barrett CTI was designed to enrich the lives of students, staff, faculty and the surrounding community. The unique cantilevered structure, colourful interior and accessible rooftop courtyard differ from standard LEED projects which tend to result in box-like, bland forms. Occupants’ health and wellbeing will benefit from enhanced air quality, ample daylight and the use of natural, nontoxic materials with long lifespans. As an educational institution, thoughtful design pieces were implemented, including sheer panels that showcase the buildings’ interior elements, optimized to function as teaching tools for students and the community.

As one of the largest net-zero buildings in Canada, the Barrett CTI is a shining example of Humber’s leadership in sustainable campuses.

The world-class technologies used to design and construct the facility, along with the technologies situated inside the building, provide an opportunity for students to immerse themselves in future-focused experiential learning opportunities, mending the gap between education and real-world scenarios.

MISSISSAUGA EXECUTIVE CENTRE Mississauga Executive Centre (MEC) is a first-class office complex, located in the heart of Canada’s sixth largest city.

Its four buildings are situated on 20 acres of land surrounded by lush landscaping, multiple outdoor leisure spaces and walking/biking trails along Cooksville Creek. It has become a preeminent property to launch many of Colliers Real Estate Management Services cutting-edge sustainability initiatives.

MEC was the first existing building in Mississauga to achieve LEED-EB Gold certification. In keeping with this tradition of excellence, MEC 2 and MEC 3 upheld their Gold distinction, while MEC 1 and MEC 4 were elevated to Platinum this year.

Non-condensing boilers were replaced with modern near-condensing modulating boilers in each building, reducing natural gas consumption by upwards of 24%. Operational changes, including damper control to regulate air flow, CO2 sensor recalibration, and hot deck/cold deck system upgrades. Also, sweeping LED retrofits throughout the complex, including the installation of occupancy sensors in the underground parking garages, resulted in over 800 MWh of electricity avoidance overall.

Recent indoor air quality testing results showed that mechanical ventilation systems were providing strong filtration of outdoor air; a central contributor to high tenant satisfaction. At MEC 1 and MEC 4, 90% of tenants said they were extremely, or very satisfied in our survey. Strong tenant engagement is critical as MEC continues to model high quality environmental stewardship in the years ahead.

KINGS DAUGHTERS AND SONS VILLAGE Environmentally friendly and sustainable design is a fundamental component of each of CSV Architects’ projects. KDS Village (Kings Daughters and Sons) - a senior’s residence which provides a high quality of life on a modest budget - is a prime example of this.

The project facilitates the KDS vision of integrated residential living with health-related support services.

To address residents’ specific needs and to facilitate aging-in-place, a generous ground floor space was included for a range of care and recreational services. All of which made use of environmentally friendly building materials and features for maximum energy efficiency.

CSV set ambitious targets for sustainable design and energy performance. With a full-time, in-house energy modeller who provides real-time, energy assist throughout each phase of a project, CSV’s team was confident they would meet their goals.

The space uses 25 per cent less energy and achieved LEED® Platinum for Homes certification through Canada Green Building Council. This performance was achieved with modest additional cost above a budget that was set before LEED certification was settled on. “We are incredibly proud of this achievement,” said Anthony Leaning, Principal at CSV Architects. “It supports our goal of helping to create equitable, healthy, and affordable communities.”

FEDERATION OF CANADIAN MUNICIPALITIES Located in the heart of Ottawa’s ByWard Market, an updated workspace provides the Federation of Canadian Municipalities (FCM) headquarters a contemporary work environment. The three-story building underwent a complete transformation towards a more open, modern, and team-centric space. CSV Architects incorporated several sustainable design features throughout.

The most important decision made was to rejuvenate and utilize their existing building rather than building new.

Following this, other sustainable features included the selection of non-toxic, low or no-VOC products, energy efficiency in the form of carbon offsets, water efficient fixtures, biophilic elements throughout, and bird-friendly glazing on windows to prevent injury.

“The project goals were to help FCM improve occupant health and achieve a LEED certification through the Canada Green Building Council, proving they walk the talk,” said Darryl Hood, Principal at CSV Architects.

This project had the wellbeing of employees in mind.

To create a people-centric space, the CSV team worked alongside FCM representatives and staff to ensure the collaborative space anticipation was met. In support of staff wellbeing, the design featured a clean and bright color palette. The design also features an eclectic staff lounge and meeting space to improve collaboration and enhance FCM’s office culture.

8 HURON BRANT DRIVE NORTH Located on the Tyendinaga Mohawk Territory in Southern Ontario, the 8 Huron Brant Drive North 4plex was an affordable housing project funded as a cost-share between Indigenous Services Canada and the Mohawks of the Bay of Quinte. This project consisted of four new affordable rental units for the Membership of the Mohawks of the Bay of Quinte (MBQ) and is located within the Community’s Huron Brant Drive Housing Development. Each unit is 1,248 ft2 and consist of 3-bedrooms, with an on-suite for the master bedroom. The design included an open concept for the kitchen, dining and living rooms with each unit having private entrance with shared parking.

The design-build team, led by AGC and Associates Inc. with LEED evaluation provided by Clearsphere Consulting, assisted the MBQ’s Housing & Band Property Maintenance Department in achieving LEED Gold certification under the LEED v4 BD+C: Homes and Multifamily Low-rise for each unit. This achievement is possibly the first project for a First Nation Community in Ontario to reach this certification.

This project also received R2000 certification by Natural Resources Canada (NRCan) for all four units, and fits into the Mohawks of the Bay of Quinte’s overall history of sustainable building approach and builds off past and current successes in constructing safe, affordable and healthy housing opportunities for the Band’s membership.

The new multipurpose building is a 17,352 m2 single complex light rail vehicle (LRV) storage facility that condenses the functionality of three individual buildings into one: an LRV heavy maintenance area, an LRV storage and maintenance area, and an administration and workshop area.

It is part of the southeast leg of the Valley Line LRT, which is anticipated to host over 100,000 trips per day with the completion of the western leg circa 2027. The Gerry Wright OMF’s completion and certification represents a major construction milestone, with the building being a striking visual highlight of the City of Edmonton’s new low floor, urbanstyle LRT system.

The Gerry Wright OMF will play a critical role in ensuring timely operation and maintenance of the Valley Line’s LRV fleet for the next 30 years and beyond, and was consciously designed to meet the City of Edmonton’s Sustainable Urban Integration principles. These principles focus on integrating all new infrastructure into existing communities and environs in a sustainable, efficient, and aesthetically suited manner.

The OMF incorporates two notable innovations in its design.

The first innovation mitigates significant heat loss during operations. This issue was resolved by designing and manufacturing specialized rubber gaskets for each catenary cable, which were then attached to each oversized bi-fold door. Once opened, air curtains found above these doors turn on, and prevent the warm interior air from escaping.

The second innovation was to rethink and refine how the OMF’s commercially-produced metal panels were co-joined.

Design innovations led to a paneling system that eliminated thermal bridging, improving the insulation performance of the exterior envelope.

Regarding aesthetics, land and water use, the building was designed with a modern, forward-thinking identity meant to enhance the surrounding commercial and industrial zone. This included extensive use of landscaping, berming, and building massing to screen open material storage and soften the industrial function of the site. There are also external cladding/ louvres used to conceal all the major mechanical rooftop equipment from the public view. Potable water is not being used for the landscaping, and water use in the facility is estimated to be at 40% below baseline.

The facility also includes future strategic measures to promote conservation, including re-using the overhead LRV wash water in the undercarriage wash cycle.

The Gerry Wright OMF features active and sustainable transportation options for staff and visitors including electric vehicle charging stations, bike racks, and close proximity to the Valley Line LRT.

Clayton Community Centre Open design process meets high performance and needs of users

By Melissa Higgs Located about 10km east of the Surrey City Centre, Clayton Heights is transitioning rapidly from a predominantly agricultural community to an increasingly urban one. Designed to feel like it is part of the surrounding forest, the Clayton Community Centre focuses on meeting the current and evolving needs of residents, with social gathering spaces that help foster wellness, connection and resilience.

The 7,000 m2 (76,000sf) Centre combines four aspects of the City of Surrey’s community services - recreation, library, arts and parks — in a seamlessly integrated facility. Previously accustomed to operating out of their own separate buildings, the four programs pooled space and resources during the design process, maximizing the potential for positive impact on both the community and their own operations.

The social fabric of the surrounding context has informed a design that addresses the needs of young people, while providing key gathering spaces to support the development of overall community connections. The unique mix of spaces combines arts and culture programming including music studios, recording studios and a community rehearsal hall, with recreational activities including a gymnasium, fitness centre, and a branch library.

1. The Clayton Community Centre is designed to fit into the surrounding forest as the area transitions to a more urban community.

2. The façade is a rainscreen assembly in which the flutes in the cladding allow the air to move from top to bottom without interruption.

6 These services are supported by a range of shared social areas and a unique mix of supplementary spaces, imagined and developed in close collaboration with the community, and designed to allow for community-led programming. Clayton Community Centre initially opened its doors in February, 2021 with reduced programming due to COVID-19 restrictions, before opening fully in the summer of that year.

Community engagement played a crucial role in the design development. Rather than simply informing neighbouring residents of the building’s progress, the architectural team invited people into the process to shape its development. In the absence of a recognized independent standard, hcma created its own social impact framework based on principles of equity, social inclusion, sustainability and adaptability. Clayton Community Centre is the first building to have been completed using hcma's framework from start to finish.

From the start, the project was aiming for ultra-low energy performance and ultimately Passive House certification. As most of the Passive House projects completed in North America have been in the residential sector, there are few completed non-residential projects from which to learn. By designing complex non-residential buildings, design professionals are charting new territory.

Natural ventilation patterns

DESIGN PROCESS From the outset of the project, team collaboration was critical for success. Working closely with the City of Surrey, the design team invested significant time in the discovery phase to understand the building's occupancy patterns. From the number of visitors anticipated during operating hours, to the energy use of the equipment in each room—all had to be considered to calculate the building’s proposed energy use. (For a more complete account of the challenges presented in the design of this project, see Charting New Territory in Passive House’ in the spring 2019 issue of SABMag.) The detailing and construction of the building was also a departure from the norm, and demanded a high-level of on-site communication and accountability to achieve the quality assurance needed to realize the exacting Passive House air tightness requirements.

The envelope, along with many other details, required greater precision in construction than for a more conventional building. The team, led by EllisDon, built a full-scale façade mockup to optimize and confirm the construction sequencing required to hit the necessary targets. The quality of work was confirmed with air tightness tests at key stages of construction to confirm the envelope met the rigorous performance

Building the future of nuclear through responsible waste disposal P lans have been laid for the construction of a highly engineered radioactive waste disposal facility in Chalk River, Ontario, Canada. The facility is being proposed as a permanent and modern technological solution to an environmental issue that goes back almost a century.

Today, Canadian Nuclear Laboratories (CNL) is seeking the support of the industry and its supply chain to move this project forward and advance the future of waste disposal in Canada.

Canada’s storied Chalk River Laboratories (pictured right) was established in 1944 on the Ottawa River, about 180 km (114 miles) from the City of Ottawa. An adjacent community, the Town of Deep River, was developed to support the site and remains home to generations of employees. The site is located on the traditional and unceded territory of the Algonquin Nation.

CNL is once again using leading-edge technology to put forward a long-term environmental solution. Taking guidance from domestic and international experience, CNL has proposed an engineered containment mound – the Near Surface Disposal Facility, or NSDF – as the solution for low-level radioactive waste at Chalk River Labs.

Waste management is a challenge facing the entire nuclear industry.

Artist’s rendering of NSDF closure phase As a fundamental component in the revitalization of the Chalk River campus, the NSDF is critical to both the long-term protection of the environment and to the continued development of breakthroughs in nuclear science and technology.

“Chalk River Laboratories is undergoing a transformative change that will propel CNL into the forefront of nuclear research in Canada and the world. The Near Surface Disposal Facility is key to this revitalization,” said Kristan Schruder, CNL Deputy Vice President of Environmental Remediation Management.

The proposed facility will include the construction of a highly engineered containment mound, site infrastructure and waste water treatment facilities. The project is estimated to cost C$365 million. A skilled The NSDF is designed to be protective of the Ottawa River workforce of 225 to 300 people will be needed to build it from the ground up. If CNL’s proposal is approved by Canada’s nuclear regulator, the Canadian Nuclear Safety Commission, construction of the NSDF is anticipated to start in the fall of 2022.

SABMag - SPRING 2022

At CNL, we are committed and prepared to implement this modern solution to an old environmental problem.

Artist’s rendering of NSDF operations phase CNL has successful experience with the engineered containment design through the construction and operation of waste management facilities in the two Southern Ontario communities of Port Hope and Port Granby, located about 100 km (60 miles) east of Toronto on Lake Ontario.

In 2021, CNL completed the closure of the engineered aboveground mound in Port Granby, with 1.3 million tonnes (1.4 million tons) of contaminated soil and industrial waste placed in the mound for safe, long-term storage.

Completed Long-Term Waste Management Facility Port Granby, Ontario, Canada

SABMag - SPRING 2022

37

The Chalk River Laboratories campus The design technology specific to the NSDF has been tested extensively. The facility will use natural and synthetic barriers that work together to isolate the waste from the environment for generations. Testing on the synthetic geomembrane done at Queen’s University concluded the membrane will stay intact for more than a thousand years – much longer than the time it will take for the radioactivity contained in the facility to decay to a safe level.

The NSDF proposal is nearing the end of a five-year, federally regulated environmental assessment and the Canadian Nuclear Safety Commission has scheduled a public hearing starting in May of this year to consider CNL’s proposal. Anyone can participate in the hearing process by submitting a written intervention or letter of support to the Commission by April 11.

1. Rendering of the building after the ReCover process.

2. The building in its current state.

In light of these facts, the ReCover Initiative was established to develop a Deep Retrofit methodology for Nova Scotia that can be implemented at a large scale.

Our goal was to achieve enough energy savings to ensure that the building could be net-zero with the addition of renewables. As such our approach involved energy savings through superinsulation AND an airtightness target of 1 ACH (passive house retrofit target), fuel switching of the building mechanicals (from fuel oil to electric), and addition of high-efficiency new equipment, including dedicated ERVs in each unit and then solar PV.. Essentially the pathway is to conserve as much energy as possible, to electrify everything, and then to offset the small amount of energy needed with renewables.

The ReCover Initiative A deep retrofit methodology to cut operating energy, reduce GHG emissions and upgrade ageing buildings

to demonstrate the potential reductions in energy consumption and GHG emissions that could be achieved by applying this methodology to the retrofit of a low-rise MURB (multi-unit residential building) pilot building in Halifax.

Conventional methods of performing deep energy retrofits are slow and expensive, because every project is custom, as every building is unique. The ReCover Initiative is based on a systematic, turnkey approach to affordable deep energy retrofits, developed in the Netherlands, called Energiesprong (“energy leap”).

The ReCover process involves wrapping the building in a new prefabricated skin and replacing the mechanical systems with smaller, more efficient components. This work is faster and less disruptive than a typical renovation, and it allows for occupants to remain in their homes throughout the work. Additionally, following a proven, systematic process reduces risk to the contractor and reduces costs to the owner.

Third & Hawkins Condo Local residents band together to offer comfort and high efficiency to downsizers

By Mary Ellen Read Located in downtown Whitehorse, this six-storey, predominantly wood-frame structure is the brainchild of three couples, none with previous construction or development experience. They joined forces with a common purpose: to develop a sustainable, community-oriented residential building that would also meet market expectations of comfort and luxury.

Enthusiastically supported by the local council, the development objective was to encourage downsizing owners to return to the city’s downtown core. Located in the well-established south-end of town, the building is only a few blocks from the dynamic urban amenities of Main Street, three parks with playgrounds are within 0.5 km, and both the Waterfront Trail and Millennium Trail (popular among urban hikers, dog-walkers, and joggers) are just steps away.

The majority of the units are 1,200 square feet with two bedrooms. The developers occupy three of the four penthouses, while the remaining units were sold 2

The building is a pinwheel shape in plan; rotated 15-degrees from the property lines to allow each unit to have multiple exposures for daylight and views to the mountains.

With the primary target market being active seniors, the building is designed to facilitate aging in place.

However, the generous hallways and wide wheelchairfriendly doorways create a sense of spaciousness that appeals to everyone. Other accessibility features include zero-threshold showers; grab-bars strategically placed throughout; lever handles on doors and faucets; under counter and task lighting in kitchens; and high-contrast edges between walls and floors for

The building is equipped with a high-efficiency central ERV system, specifically a RG 2000, by Winnipeg-based Tempeff. Acting as the building’s lungs, the ERV not only recovers heat, but also factors in humidity making it the best choice for occupant comfort in a cold, humid climate. The ERV makes use of Dual-Core technology allowing for continuous fresh air supply and frost-free operation in this climate.
