Interior Design Award


Jury Comment: At a time when the nature of work is in flux, the transformation of six floors of rigorously repetitious 1970s office space into a dynamic, flexible and inspiring workplace provides cause for optimism. The open, collaborative spaces and non-specific perimeter workstations flow through all levels, encouraging mobility and personal choice of working and relaxing environments throughout the day. Sit/stand desks, lighting programmed to support natural circadian rhythms, and 20 living walls contribute further to psychological and physiological wellbeing.

The first project in Canada to be certified under Version 2 of the WELL Building Standard, the new headquarters for BNP Paribas , the French international banking group, exemplifies current best practice in employee-centred office design. To alleviate overcrowding and bring its 140 staff under one roof, the company chose to relocate and refit 140,000 sq.ft. of space spread over six floors of an existing 1970s office building.

From the outset, the aim was to achieve WELL Building certification and to create a dynamic work environment that would promote social interaction and collaboration as well as the health and comfort of occupants. The challenge was to meet the client’s desire for a fluid, flexible, non-Cartesian layout of space within the physical constraints of the existing structure, which included working with the two feet by four feet ceiling grid.

This led to the development of a workplace where the main open spaces are divided into several zones alternating those intended for work, collaboration and rest. Work areas are not assigned; employees can settle wherever they want in the building, or even telecommute. The workstations are arranged at the perimeter, so employees benefit from maximum natural light.  Common spaces are located at the core of the building and include glazed meeting rooms, changing rooms, and sanitary facilities.

To energize the occupied spaces, the strategy was to create what the design team refers to as “organized chaos” through the choice and arrangement of lighting and office furniture. Artificial lighting integrates a variety of high-performance luminaires, adapted to the functions of the different areas with dynamism in mind. As required by WELL, the lighting is designed not to disrupt the occupants‘ circadian rhythms.

The office furniture system includes a spine that integrates all the wiring required. Workstations can be moved along this spine in either direction to modify the space and employees can alternate between sitting and standing positions. Low VOC materials minimize airborne pollutants and 20 living walls help purify the air while enhancing the human biophilic response.

Institutional (Small) Award

Mackin Tanaka Architecture

Jury Comment: With the growing concern for the embodied carbon in our built environment, this small building for the Tsawwassen First Nation stands out for its commitment to that cause. In fact, its widespread use of wood and its projected low operating energy demand, may make the building carbon negative for a decade or more. In addition to its low environmental impact, the location next to the Salish Sea and on the Pacific flight path for migratory birds, make it an invaluable teaching tool for Indigenous youth – and for all of us.

This community centre for young people and their families provides spaces for drop-in and scheduled programs and community gatherings. Located on treaty lands south of Vancouver, the waterfront site is part of a unique cultural and ecological area, the meeting place of cultures and ecologies.

The design of the two-storey building bridges tradition and modernity, its narrative unfolding through its form, structure, materials and relationship to site. In this way, it teaches future leaders 4,000 year old lessons about stewardship of the land and sea.

An interactive design process, involving children, teens, leadership, and artists guided the development of the program and the approach to building design. Among the program elements that emerged from this collaborative process were, climbing walls, art and music studios, MMA and weight room areas, a teen lounge and an outdoor oriented activity space for the younger set. TFN citizens of all ages expressed their commitment to maintaining the health of their traditional lands and using environmentally responsible and durable materials and systems for their new building.

The gymnasium on the second floor with a Sportec underlayment 4 mm overlaid with Sportec UNI classic 4mm. Damtec wave 3D 17/8 was installed as a resilient layer (acoustic insulation under screed) over the entire second floor, with 6 mm Damtec estra installed as a de-coupler strip around all wall perimeters, logs, MEP routing etc. Sportec and Damtec supplied by Ideal Fit.

Prefabrication and Modular Construction

The thermal performance of off-site prefabricated buildings and building enclosure systems

By Val Sylaj and Brian J Hall

As designers and owners are becoming more aware of the environmental impacts of the construction industry, including the types of materials used, more stringent requirements are being imposed by specifiers, and national codes and standards.   

This article provides some insights on the important measures of prefabrication and panelized systems on the thermal performance of buildings, the energy consumption, and the financial impacts to the investors.

A recent report from Dodge Data and Analytics published in 2020 shows a significant interest by the construction industry in prefabrication and modular construction mainly because of the improved productivity, reduced timeline, and cost, better sustainability performance, etc.

An earlier report from Dodge Data and Analytics published in 2011 had also highlighted the following as the underlying drivers and benefits of prefabrication and modular construction: (1) Improved productivity and quality are key benefits in its usage, (2) Positive impacts on budget and schedule performance are widely experienced, and (3) Construction sites are ‘greener’ due to less waste being generated, and safer due to working with structure assemblies and modules produced offsite. 

Although major advances have been made in both prefabrication and modular construction since the 2011 report, many of the above mentioned factors are still consistent with the findings of the latest report from 2020. 

What is Prefabrication and Modular Construction?

With rapid population growth, the construction industry is always challenged to adapt its technologies based on the market demand such as the need for taller buildings, reduced onsite construction times, enhanced building performance, etc. Prefabrication and modular construction are certainly a solution to most, if not all, of these demands. 

Prefabrication is a construction method that involves fabricating and assembling building components offsite. It can refer to both flat elements (often known as prefabricated panelized systems), or to modular volumetric units that typically include complete spaces of a building such as an apartment unit, hotel room, jail cell, etc. In either case, prefabrication construction also provides innovative solutions in buildings where the entire building envelope can be fabricated offsite using prefabricated building components.

In addition to the need for accelerated building construction technology and consistency in quality, prefabrication and modular construction are also being considered to address concerns with site-specific skilled labour shortages. With prefabrication that is completely performed at an offsite facility, plant workers can be trained to perform specific skilled trades such as electrical and plumbing that form part of the finished element or room. 

Standard building construction practices require individual building components or materials to be delivered to a job site, stored and then placed or installed by labourers from multiple trades. This requires significant on-site space as well as time for setup and construction. Another very time-consuming on-site operation process is the exterior finish of the final building façade.                                                               

Conversely, off-site prefabricated components are delivered ‘just-in-time’ and installed by a smaller crew of skilled installers/erectors, directly from the truck onto the building, with the façade and architectural finishes already complete.    

It is clear that prefabrication is an ideal construction technology with minimal site disturbance and less labour required compared to traditional construction. Another important factor is improved safety, mainly because the work is done at ground level at a prefabrication facility, instead of working at elevated heights which is common with traditional construction. Further, the safety measures such as physical distancing during a pandemic can be easily implemented with very minimal or no effect on production.


Design practice: Rethinking Multi-Unit Residential Design

Optimizing flexibility, affordability and construction efficiency

By Michelle Xuereb, Dev Mehta, Adryanne Quenneville and Tiffany Wong of BDP Quadrangle

The world is in a period of increased urbanization. In 2018 the United Nations estimated that by 2050 68% of the global population will be living in an urban area. Urban population growth has driven up land value and the costs associated with residential building construction. For most, living in an urban area means residing in a multi-unit residential building (MURB).

As the costs related to urban residential development have increased, the average unit size has decreased. For example, a typical two-bedroom-plus-den unit in one of Toronto’s older stock of residential buildings is usually around 1,000 square feet. Current residential developments fit the same program into roughly 750 square feet.

This squeezing of the floor plans, however, has reached its breaking point. Residential units can only be tightened so much without sacrificing the quality and functionality of the space. When every room is competing for floor area, designers need to get creative.

In March, BDP Quadrangle held a studio-wide ‘Shrinking Spaces Charrette’ to come up with innovative solutions for small units. We took a typical residential unit apart – examining every inch of space from the master bedroom to the pantry shelf – to find creative new ways of maximizing square footage within a limited space.

The future MURB unit does away with fixed rooms with set programs. Isolating in response to the pandemic has prompted all of us to find more flexibility in our living spaces, and also to question how MURB design can go further to support a sense of community and foster interaction with others while still maintaining privacy and a safe distance if required.

This pandemic experience has equipped us with a direct and immediate understanding of the specific desires for an improved at-home wellness experience – such as a need for both togetherness and separation from other family members; having a place to stow away a computer at the end of the day; the possibility to grow vegetables on a balcony; and the benefit of socializing with neighbours. We identified a need for more resilient, sustainable, flexible, and healthy spaces – all within a small footprint in order to maintain an affordable unit.

We began rethinking MURB units by asking: what would happen if we reduced or eliminated set programs? In order to optimize flexibility, we propose blurring the lines between rooms, rather than delineating them with demising walls.

To accommodate this, the building is designed with a structural column grid instead of shear walls, as is typical of Toronto construction. This structural system also uses less concrete – thereby reducing the building’s carbon footprint. For other elements that are typically fixed in place, such as the plumbing stacks and mechanical shafts, we arranged them in a manner that allows for an open plan: the kitchen, bathrooms, and laundry closets are consolidated on the perimeter of the unit. These shifts allow for a more flexible floor plan.


Sponsored content: Ontario Association of Architects Headquarters retrofit

Inline Fiberglass elevates envelope performance

Dubbed “Wings Over Don Mills” when it opened in 1992 for its Toronto neighbourhood location and for its uplifted winged roof framing, the three-storey, 21,400-square-foot Ontario Association of Architects (OAA) Headquarters was deemed in need of a retrofit.

The goal was to refresh the interior and improve energy performance – in fact, to meet the 2030 Challenge which is intended to reduce greenhouse gas emissions in new buildings, developments and major renovations. As a result of the retrofit, the OAA Headquarters has moved to electrical power and is targetting a remarkable 85% energy use reduction to an impressive 55 kwh/m2/year.

The envelope upgrade included additional insulation, curtainwall retrofits, and new fiberglass frame, triple-glazed windows by Inline Fiberglass. Fiberglass frames combine strength with very low levels of conductivity, and have the lowest embodied energy when compared to other common window frame materials. They also resist corrosion for long life expectancy. Our Series 3000 windows are Passive House International certified.

Inline’s products can be treated with specialized resins that have been tested and are in compliance with CAN/ULC S134 test protocol allowing them to be used in non-combustible applications when approved by building inspectors, as in the case of the OAA project.

According to David Fujiwara, the architect of the retrofit, “Fiberglass frames were considered for the OAA office windows because of their thermal effectiveness, ability to carry a triple-glazed unit, slim profile and strength. They met all the requirements of the building code and of the project.

The replacement windows needed to fit within the existing frame opening available, so removal of old thermally unbroken aluminum frame windows, site measuring and installation of the new frames for an airtight fit was an essential part of the work. Coordination was also needed with the electrochromic glazing supplier View Smart Glass. The final touch was the addition of 3M light redirecting film to the upper transom strip of window.”



Hobin Architecture – Existing Building Upgrade Award

Jury: This conversion of a 1940s City Works Yard building into an Innovation Hub demonstrates how the careful and pragmatic adaptive reuse of an unprepossessing building can transform the dynamics of a neighbourhood, create a sense of place, and at the same time support social and  cultural continuity. The act of preservation conserves embodied energy in the existing structure and avoids that associated with a new building. The LEED Gold  certification is exemplary for an adaptive reuse project.

Also known as The Innovation Centre at Bayview Yards, Cours Bayview Yards is Ottawa’s epicentre for entrepreneurial programs and services. The centre was developed within a 4,460 m² (48,000ft²) industrial building, originally constructed in the 1940s as a City Workshops facility, and now having historical importance as one of the few survivors of a once sprawling industrial area.

The project showcases the potential for the adaptive reuse of vacant industrial buildings and demonstrates that such adaptation can be done both affordably and sustainably. Aside from retaining more than 85% of the original structure, the project integrates a broad spectrum of design strategies that address issues of economic, social and ecological sustainability.

These include maximizing thermal performance through the use of premium insulation and fenestration, achieving an envelope performance twice that required by the MNECB; specification of high-efficiency mechanical and electrical systems, supplemented by a comprehensive building automation system that modulates equipment runtimes to varying building loads and not fixed schedules; embracing alternate modes of transportation and urban agriculture.

The Well, a multipurpose space for events, parties and exhibitions, is also accessible for casual use when not in use. Daikin supplied the Maverick roof-mounted air handler unit, and SmartSource water source heat pumps.

REACH GUESTHOUSE, Prince Edward County, ON

Kearns Mancini Architects – Residential [Small] Award

Jury: A meticulous rehabilitation and upgrade project, that converts a 19th century four-bedroom farmhouse into a 2-bedroom guesthouse, with the original post and beam structure being enclosed in a new high-performance building envelope. The addition of a Passive House standard kitchen, dining and living area to the rear of the house integrates seamlessly with the original, being barely discernible as a new structure. An elegantly detailed project notable for its restraint.

Originally a four bedroom, one‐bathroom house, this 19th century farmhouse was renovated into a two bedroom, two-bathroom house incorporating Passive House EnerPHit standards. Conceptually, a new insulated, airtight structure was built over the existing post and beam house. The rear of the building was substantially rebuilt to accommodate a large, double height kitchen, dining and living space. The new front gable window was intentionally oversized, offering visitors a glimpse of the original arched front gable window within. In future, the house will serve as a guesthouse for a new great house on the same property. In the interim, it serves as a vacation property for visitors to Prince Edward County.

The original post and beam building was exposed and meticulously cleaned and sealed inside an airtight envelope. Structural Insulated Panels were used as a new building envelope, providing a continuous R43 insulation value in the walls. New roof trusses were added to the existing structure, surmounting the existing roof and walls. This allowed for a 600mm cavity to be filled with new cellulose insulation, providing a continuous insulating value of R67. To achieve an airtight seal, all ground level floorboards were lifted, and an oriented strand board sub-floor installed before the floorboards were re-laid.

Battersby Howat Architects – Residential [Small] Award

Jury: A beautiful example of how the transparency, openness and site responsive character of traditional West coast Modern design can be integrated with the high-performance requirements of Passive House. The project is also notable for its prefabricated cross laminated timber structure. The project team also made a commendable effort to provide educational and other benefits for the community, creating a video series about the project and by donating demolition and surplus construction materials to Habitat for humanity.

Located on the West Vancouver waterfront, the West Bay Passive House achieves a rare fusion of beauty and efficiency in its pursuit of net zero energy performance. With a super-insulated, airtight envelope and highly efficient mechanical and electrical systems, the home achieved a Passive House Plus certification, an Energuide Rating confirming zero tonnes of Green House Gas emissions, and net-zero Giga-Joules of energy consumption when measured on an annual basis.

Other notable attributes of the house include the use of a Cross-Laminated Timber (CLT) superstructure constructed on top of a concrete foundation, floor-to-ceiling glazing for uninterrupted ocean views, and a passive solar design achieved through a combination of built-in and environmental shading.

Located in one of Metro Vancouver’s luxury home markets, this project introduced a sustainability-conscious design ethos to the area by creating a home that was both architecturally pleasing and Passive House certified. Capturing the ocean view was critical to the success of the design so triple-glazed thermally-broken glazing systems were used to minimize heat loss and overhangs designed for passive shading. The superstructure was built with factory prefabricated CLT panels to provide a robust and durable building core that would also store carbon. 

By prefabricating the components, the construction schedule was reduced by two months with a significant reduction in waste.

The active mechanical system consists of an energy recovery ventilator (ERV) for ventilation and a heat pump hot water tank. The same small heat pump also feeds a heating and cooling coil on the ERV’s supply lines and is able to provide a comfortable indoor environment for all occupants.

  • Energy intensity (building and process energy) = 36KWhr/m2/year
  • Energy intensity reduction relative to reference building under HOT 2000 V11 = 99.87%
  • Recycled material content by value = 10-20%
  • Construction waste diverted from landfill = 84%

Schock Isokorb provides structural thermal breaks.

Balanced ventilation with energy recovery provides continuous filtered fresh air and ensures optimum indoor air quality. The active mechanical system consists of a Zehnder ComfoAir Q600 energy recovery ventilator (ERV) for ventilation and a Daikin heat pump.

McFarland Marceau Architects Ltd. – Institutional [Large] Award

Jury: A remarkable response to the challenging industrial workshop program and an equally challenging climate. The result is a refined, restrained and beautiful building, with a great sense of warmth emanating from the exposed wood finishes and the high levels of natural light. The requirement for large expanses of solid wall is cleverly used for the collection of solar heat. And, the overall performance metrics are impressive.

With a population of 13,000, Dawson Creek is located in the Peace River region of northern British Columbia, the western extremity of the Canadian Prairies. The city has become the regional centre for the province’s energy industry and home for BC’s ‘Energy College’. The recently completed Trades Training Centre is the third phase in a campus expansion plan that has previously included a Centre for Excellence in Clean Energy Technology (CECET) and a 26m-high cross laminated timber (CLT) training tower for the college’s wind turbine maintenance program.

Seeking LEED Gold certification, the Trades Training Centre subverts the sprawling pattern of adjacent rural development by framing positive public outdoor space and inverts the standard trades building typology in favour of one more suited to a multi-disciplinary, interactive approach to trades education.

The 5,600m2 Trades Training Centre provides workshops for the instruction of carpentry, welding, plumbing, millwright, and wind turbine technology, as well as student commons, classrooms, and offices. The building is located at the entrance to the campus, close to the phase 1 CECET building and linked to it by a colonnaded walkway.

These connected structures define three sides of an open courtyard that embraces visitors and forms a new and welcoming entrance plaza for the college. The colonnade has a continuous CLT rear wall and an exposed CLT roof supported on laminated veneer lumber columns. The colonnade continues into the trades building where it defines the edge of a student commons that looks out to the courtyard. The student commons is screened from adjacent classrooms with a playful curved partition of LVL posts.

Beyond the student commons, the workshops are positioned either side of a ‘shops commons’ and have overhead doors opening onto it. The shops commons is a new type of space for the trades program that provides flexible, interactive space for the workshops – and was also deemed essential to accommodate shipping and receiving functions in a climate where winter temperatures can dip well below -30°C.

The energy requirements of trades buildings in northern climates are extreme, due to the high ventilation demands of the shops. The building mitigates this by integrating architecture and structure with its lighting and mechanical systems. The heat is supplied by a biomass-fueled boiler that burns waste wood. To achieve optimal performance, the biomass boiler is oversized and was installed in advance to supply hydronic heat to two additional buildings as a campus energy system.

Quadrangle (Architect of Record) and Dubbeldam Architecture + Design (Collaborating Design Architect) – Residential [Large] Award

Jury: This conversion of the original 1939 Bata Shoe Factory provides the small town of Batawa with an amenity uncommon in a community of this size: mixed income rental accommodation with recreational amenities for residents; a daycare and a community art space. The project is exemplary for its respectful adaptation of an important part of Ontario’s industrial heritage, its well-considered mixed-use program, and its rehabilitation of the former parking lot that surrounded the building. In addition to the carbon benefit of retaining the concrete structure, the project has very good energy performance.

The late Sonja Bata pursued her passion for architecture and the built environment through the revitalization of the town of Batawa, located 30km east of Belleville on the Trent river. As a sustainable community and satellite town adapted to 21st century living, where residents could live close to nature but maintain a connection to work through broadband, she envisioned Batawa as a model community for social and environmental sustainability.

The renovation to the Bata Shoe Factory is an ambitious adaptive re-use project located at the gateway to Batawa. Central to Mrs. Bata’s vision for Batawa was the conversion of the manufacturing facility built by her family’s shoe empire during WWII, into a modern mixed use residential, commercial and community building with a light environmental footprint and a social mandate.

With a focus on integrating the most sustainable approaches – the renovated building retains the original 1939 concrete structure; the HVAC systems are powered entirely through a geothermal energy source; and any new materials or systems are as sustainable as possible – the resulting renovated building is a model for increased housing density in a rural setting with the lightest impact on the environment and a focus on community and social sustainability.

Aside from not building at all, the lightest impact on the environment is accomplished through adaptive re-use strategies – retention and rehabilitation of existing buildings. With close to 80% of a building’s embodied carbon found in the structural components, retaining and highlighting the existing concrete structure of the building in combination with new sustainable materials and systems was one of the key strategic decisions for this adaptive re-use project.
