mitigate and adapt! BuIldInG our CommunItIes In tHe AGe oF ClImAte CHAnGe The weather was once the worry of only farmers and parents dressing children for school. Today, climate change makes front page and business headlines. Stories of recent natural disasters and their impact on our economies have heightened everyone’s concern − and rightly so.

A 2011 united nations report on disaster risk reduction identified that losses from disasters are rising faster than gains made through economic growth across many regions. In Canada, the national roundtable on the environment and the economy (nrtee) predicted that by 2020, climate change impacts could cost the Canadian economy up to 1% of Gross domestic product (Gdp), or $5 billion per year. that cost could climb to $43 billion per year by 2050. If 2013 was any indication, these predictions appear accurate. According to the Insurance Bureau of Canada, 2013 was the most expensive year on record for insurable losses in Canada, with $3.2 billion in weather-related claims. the 2013 Calgary flood alone is estimated to have cost upwards of $6 billion, including non-insurable losses.

the scientific research indicates that our climate will continue to change, with rising temperatures and sea levels, fluctuating rainfall and snowfall patterns, and more unpredictable extremes ranging from floods to droughts and freezing winters. the certainty of that reality has a direct impact on how we define and grapple with the concept of sustainability. While sustainability is most commonly understood in terms of reducing the immediate impact of human activity on the environment, climate change and other environmental and social pressures are illustrating that sustainability is an even more complex goal as we search for solutions responsive to a dynamic and changing world. As we strive to reduce greenhouse gases (GHGs) for example, we must also prepare for a world of more uncertain weather extremes wrought by changes to our climate that are by now inevitable.

A 2012 report from the Insurance Bureau of Canada stated that “climate change is likely responsible for the rising frequency and severity of extreme weather events, such as floods, storms, droughts and fires since warmer temperatures tend to produce more violent weather patterns.”

resIlIenCe: more tHAn A BuzzWord We have been hearing a lot about sustainable construction over the past few years. now “resilient construction” are the new buzzwords. “resilience” has become a cornerstone of “sustainability”. When it comes to our communities, resilience can be defined as our ability to maintain structure and functionality in the face of turbulent internal and external change. more precisely, the u.s. department of Homeland security (dHs) defined resiliency as the ability of any system (infrastructure, government, business and citizenry) to resist, absorb and recover from or successfully adapt to an adversity. Community functions decline swiftly as citizens respond to a disaster. A more resilient community can more quickly restart local services (utilities, businesses, schools) and adapt, as necessary, to a “new normal”. these communities avoid major loss or recover more quickly because they have taken measures to minimize a disaster’s impact. those measures include: improved land-use decisions and building code implementation as well as the construction of resilient infrastructure, to name a few. 3 the key to disaster recovery is not only to get essential services back up and running, but also to get people and their communities back to their daily routine – work, school, home-life, etc. that means buildings and structures must not only resist damage caused by adverse events, but must also be in a condition suitable for occupancy as soon as possible. For example, having schools that are operational after a major event helps create a sense of normalcy and mitigates the massive financial and emotional hardship on the community. While resilience and lowering our environmental footprint are both central to sustainability, they are often considered independently as two separate strategies that are sometimes at odds, involving trade-offs and a balance of priorities. unfortunately, that balancing act is currently failing in many of our communities. the trend in Canada, especially for structures that are not owner designed, built, and occupied is to maximize profitability by simply satisfying the least stringent provisions of the local building code.

5 412 Building communities in the age of climate change sabMag -our SPRING 2016

tHe mIssInG lInK to date, most building code requirements have an emphasis on life safety, i.e., they do not aim to prevent major damage or total collapse of a building or other infrastructure asset, but only to ensure that occupants can be safely evacuated prior to or during the event. However, excessively damaged buildings and infrastructure impede recovery in communities. the speed of a community’s recovery is determined in large measure by the resilience of the community’s infrastructure. even in our best practice codes, in the form of “green construction” certification programs, the focus is almost exclusively on energy, material, water conservation, indoor environmental quality and site selection/development. While these are important aspects of sustainable building design and construction, plans for resilience are not yet inherent in these programs. Communities built to last start with comprehensive planning, including stricter building codes that produce robust structures with long service lives.

tHe resIlIenCe oF ConCrete Consider this staggering fact: since the 1970s, property losses by decade have increased by more than 3500%. our communities require proactive plans to mitigate and recover from disasters. those plans must include conscientious construction methods using durable, resilient and sustainable materials. Concrete is an example of such a material; it is designed to absorb large static and dynamic loads and resist damage due to snow, flooding and fires. Wall, floor, and roof systems constructed of concrete products offer an unsurpassed combination of structural strength and wind resistance. Add hardened exterior finishes for walls and roofs and a home or business will have the best combination of strength and security available. Concrete products are resistant to wind, hurricanes, floods, and fire. As a structural material and building exterior skin, it has the ability to withstand nature’s normal deteriorating mechanisms as well as natural disasters. properly designed, concrete products are resistant to extreme loading conditions such as earthquake and blast loads. And concrete is GHG efficient, offering thermal mass based energy efficiency to buildings, low carbon pavements and durable infrastructure with low maintenance and long service life.

plAnnInG For A sustAInABle Future the residents of more robust cities and towns experience major benefits from the overall improvements associated with resilient building practices. they include: fewer burdens on local services, a more stable local economy that provides consistent sources of money to run the municipality, and a more enduring legacy for future generations.

Concrete products are made of natural raw materials (stones, gravel, sand, cement) which are locally available almost everywhere. this helps minimize the whole lifecycle impact on the environment when compared with other construction materials. Additionally, almost 100% of a concrete building can be recycled, no matter how heavily reinforced.

Builders, architects, and designers have come to recognize that more durable structures also reduce the impact communities have on our planet. For example, multiple academic studies illustrate that the passive energy-efficiency benefits of concrete, via its thermal mass, represent gains in efficiency of up to 8% over other materials, with corollary benefits for reducing GHGs. typically, this more than makes up for the energy and GHG impact of the cement and concrete manufacturing process. more importantly, and as many real world examples demonstrate, integrating concrete’s thermal mass as a design strategy and pairing it with passive and/or active radiant heating and cooling systems can magnify efficiency benefits by a factor of ten. real world examples show this holistic approach yields energy-efficiency improvements in excess of 70% over the model national energy Code for Buildings.

Innovations in the cement and concrete sector are further enhancing the lifecycle sustainability benefits of concrete. For example, in the last 20 years, the industry has reduced the energy required to make a tonne of cement by about 20%. Additionally, the recently introduced lower carbon cement — Contempra — reduces Co2 emissions by a further 10% compared to regular cement. If Contempra were to replace all cement consumed in Canada, it would save almost 1mt of GHG emissions per year. other emerging technologies including carbonated concretes and related carbon capture processes promise to dramatically reduce the carbon footprint of the built environment. When taking the broad view of sustainability, and acknowledging the realities of our future climates, concrete is a critical component of building safe, lasting and environmentally efficient communities. It is climate-friendly and climate-ready.

STRONG, DURABLE, AND LOW MAINTENANCE Concrete products last decades longer than alternative building materials. not only is concrete’s structural stability maintained for longer periods, it is non-combustible, preventing the spread of fire from one unit or one building to another. It is resistant to moisture and doesn’t rot or mold. And it is sufficiently strong to resist impacts, blasts and natural catastrophes like earthquakes, tornadoes and floods.

ENERGY-EFFICIENT the ability of concrete products to store energy (their thermal mass) helps moderate interior temperature conditions, allowing a more constant temperature both in cold and hot regions. It improves a building’s “passive survivability” in the event that services such as power, heating fuel, or water are lost — minimizing energy demands for the city as a whole and reducing the GHG emissions from heating and cooling energy.

COMFORTABLE Concrete products have intrinsic properties of acoustic insulation. this can help amplify sound within a space or dampen it between spaces. Concrete buildings can measurably reduce sound transmission between residential units, giving occupants more privacy.

EMISSION-FREE An inert substance when cured, concrete is emission-free and will not emit any gas, toxic compounds or volatile organic compounds.

VERSATILE While strong and functional when hardened, concrete’s plasticity when freshly mixed lets designers adapt it to whatever form, shape, surface and texture they can imagine. Innovations such as ultra-high performance concrete, photocatalytic

concrete and pervious concrete are also enabling new and creative uses.

IDEAL FOR ADAPTIVE REUSE Because of concrete’s strength, sound attenuation, and fire resistance, concrete buildings can easily be converted to other occupancy types during their service life. reusing buildings in this way can help limit urban sprawl and further contributes to the conservation of our resources and preservation of the environment.

COST-EFFECTIVE thanks to their durability, resilience, low maintenance requirements and energy-efficiency, structures built with concrete products reduce operating costs related to operational energy consumption, maintenance, and rebuilding following disasters. Insurance costs for concrete buildings during the construction and operating phases have also been shown to be significantly lower than for buildings constructed with combustible, moisture-sensitive materials.

100% RECYCLABLE Concrete products can be recycled as aggregate — for use as sub-base material in roadbeds and parking lots, for gabion walls, as riprap to protect shorelines or in other applications — or as granular material, thereby reducing the amount of material that is landfilled and the need for virgin materials in new construction.

PRODUCED LOCALLY Concrete is typically manufactured within 160 kilometers of a project site, using local resources. this greatly minimizes shipping and pollution and makes a significant contribution to the local economy.

UBC’s new Pharmaceutical Sciences Building claims six awards For Nick Maile, the only thing better than having a building he helped plan and develop win a series of major architecture awards, it’s seeing the people who use the building truly enjoying it. The development manager for UBC Properties Trust believes the university’s new Pharmaceutical Sciences Building is “architecturally pleasing, but any building, no matter how beautiful, if it doesn’t work for the students and faculty, it’s not a success. This one, though, is incredibly lively – people like to be in it and they use every space.” “At UBC, we are trying to be on the leading edge of sustainability and energy efficiency,” says Nick, “but it’s definitely a challenge with a building like this, where there is a data centre in the basement plus a lot of a lot of laboratories and many fume hoods.” (Fume hoods limit exposure to hazardous chemicals or toxic fumes, but they are energy-guzzlers: one fume hood alone can use more energy than three typical B.C. homes.) For help, UBC turned to BC Hydro’s New Construction Program, which provides funding for an energy-modeling study – a simulation of how a building might function throughout a full year if it’s designed and built with a variety of energy saving measures – along with additional financial incentives for implementing those measures. The energy-saving measures include capturing waste heat from the data centre and recycling it into the building, as well as daylight sensors and a low temperature water system. Together, these measures are estimated to add up to about 1.2 million kilowatt hours of savings every year over a similar building that does not include them. In addition, says Nick, “The incentive from BC Hydro for installing these measures really does help. It may be a small percentage of the overall construction budget, but we can give that money back to the Pharmacy people to use for long-term operations. So not only does the university win by saving on energy use, the department wins as well.”

Ontario Regional Winner and Technical Award Winner

BILL Fisch FOREST STEWARDSHIP AND EDUCATION CENTRE

Whitchurch-Stouffville, ON

JURY COMMENTS: The first Living Building Challenge contender in Ontario, this benchmark project goes beyond net zero energy by meticulously pursuing a range of familiar conservation strategies including: a high-performance envelope with R-40 walls and R-60 roof; a window-to-wall ratio of less than 30%; and triple-glazed windows oriented for optimal solar orientation. A 35kW photovoltaic array contributes to the net positive energy result. Other notable achievements include net zero water, with rain and well water meeting 100% of occupant needs.

Site plan

The new, 370m2 Bill Fisch Forest Stewardship and Education Centre [BFFSEC] is located at the heart of the Hollidge Tract in the York Regional Forest. It provides space for education, meetings, and operations, helping visitors learn about the importance of natural resources and forest ecosystems. As Ontarioâ&#x20AC;&#x2122;s first contender in the Living Building Challenge [LBC], the project team envisioned the BFFSEC functioning as an integral part of the forest ecosystem. To achieve this goal, the facility would have to run on only the zero-carbon energy provided by the wind and the sun, generating no pollution or greenhouse gas; it would have to capture rainwater, returning it to the watershed as clean as when it arrived; and it would have to be uniquely rooted in its place, reflecting the natural landscapes that surround it.

Fresh air is provided via ERV and HRV according to the minimums of ASHRAE 62.12010 and controlled by CO2 sensors. Lighting is connected to automatic controls for occupancy and daylight adjustment. Constructed entirely of wood, and accented with stone, BFFSEC was designed to reflect the materials of the surrounding forest. To meet the LBC Red-List requirements, all building materials had to be free of toxic substances or compounds. Extensive research was conducted to source locally manufactured, RedList-compliant materials that would not compromise performance, including Black Spruce glulam beams and FSC-certified CLT [cross-laminated timber] panels from Quebec. The comprehensive and meticulous approach to the design of the BFFSEC has resulted in a project that represents a new benchmark for building performance in eastern Canada.

GROUPE DYNAMITE ATRIUM

Montreal, QC

JURY COMMENTS Injecting life into a dead space between two large floor plate industrial buildings, this project achieves the greatest possible benefit to the companyâ&#x20AC;&#x2122;s employees with the minimum possible intervention. Despite the lack of an overt energy strategy, the atrium addresses issues of community, light and air, wellness, material efficiency and building life cycle - all of which are key aspects of sustainability. The simple form of the atrium is clad in high-performance, low-emissivity double glazing [1]. The structural frame is made from black spruce glulam, with simple steel connections [2].

Site plan

Aerial view - the project fills the space between two buildings

sabMag - SPRING 2016

The design workshops, marketing department and distribution centre were housed in vast warehouse-like spaces with no access to natural light. To create a better working environment for its 400 employees, Groupe Dynamite took the initiative to create an interior ‘oasis’ - a glazed atrium space bathed in natural light - by roofing over an abandoned space left between two of its buildings. One of the principal concerns for the project was that the construction of the new Atrium should not disturb the daily operations of the workshops and the distribution centre. Another was to design the structure to avoid unwanted or uneven snow accumulation, and the consequent need to reinforce the adjacent roofs. Other drivers of the design were the desire to create a dynamic and attractive collaborative space with programmatic flexibility, provide much needed access to natural light, maximize the use of wood for its environmental attributes, and minimize the use of interior finishes. Unifying the two existing buildings, the atrium is characterized by a simplicity of formal and material expression. A transparent skin of high-performance, low-emissivity double glazing covers a wooden skeleton and reveals the life inside the building, otherwise hidden from the outside. The glass roof floods the Atrium with natural light, creating a bright, open and transparent space. The bricks of the existing walls were left exposed. Similarly, the steel connections of the glulam frame are also left exposed as a reminder of old industrial structures. The result is an interior space with much the same material character as a typical Montreal alley. Clerestorey windows in the existing side walls, which had previously been covered over, were opened to reintroduce natural light to the adjacent work spaces. In addition, some light fixtures were placed on the side walls to light the atrium during the evening when the new space is sometimes used for fashion shows, parties and special events.

4 5 The high-performance glazing prevents overheating in the summer and reduces heat loss in the winter. The high volume encourages the stack effect and natural ventilation can be supplemented by mechanical means via two ducts that run longitudinally at high level. During the winter, the heat escaping from the adjacent buildings is sufficient to keep the atrium at a comfortable temperature. As the site is located in an industrial park, employees did not have easy access to more congenial places to meet, nor suitable options for lunch, without having to take their cars. They have quickly appropriated the Atrium, and use it as an informal place for creative sessions, meetings, exchanges of ideas and relaxation - as well as eating lunch in the 540m2 cafeteria. The atrium has encouraged employees to initiate and participate in group activities before, during and after work. In this and many other ways, this elegant and economical intervention has maximized the benefits to Groupe Dynamite and its employees using the absolute minimum of materials.

The renovation of this 84m2 home in Torontoâ&#x20AC;&#x2122;s Roncesvalles neighbourhood was completed in May 2014. The occupants, co-founding partners of a Toronto-based sustainable architecture firm, acted as both architects and general contractors, with their two young children in tow. The property is small, with a front yard, detached garage, and proximity to schools, shops, and the ownersâ&#x20AC;&#x2122; architecture office. Two main considerations were to maximize energy efficiency and the apparent space within the small 42m2 footprint on each floor. The occupants wanted to maintain the brick structure

and traditional character of the building while retrofitting it with a high-performance envelope and energy efficient systems. The occupants also wanted ample outdoor space for the children to play. The second floor includes a shared kids bedroom with bunk beds, a playroom/guest bedroom, a master bedroom and a bathroom with laundry facilities. The main floor living room acts as a family area, while the basement was underpinned and finished as a separate apartment unit for added income. The large tree in the front yard was preserved and a green roof was installed over the front porch. The side terrace act as a second living area for the family in the warmer months. With two air changes per hour at 50 Pa, the house is extremely airtight for a renovation project.

5 The ERV and boiler are both small, compact and efficient. All windows in the project are triple-glazed fiberglass units. An operable triple-glazed thermal skylight was installed over the staircase, allowing light to penetrate both levels of the home and promoting stack-effect passive ventilation in the summer months. A solar tube was installed in the upstairs hall, significantly brightening the otherwise dark space. The open and naturally bright communal room creates a warm and inviting space for the family to spend time together. The large storage areas enable family clutter to be cleared away restoring a sense of serenity to the space.

The airtight envelope, continuous insulation and high-performance boiler, about the size of a backpack, make heating and cooling the home easy and efficient, with a 92% reduction in annual space heating over the original building. Fresh air and ventilation is provided by two Energy Recovery Ventilator units, one for each dwelling unit. In the walls, 100mm of water-blown closed-cell 2-lb polyurethane foam, gives an an R-value of 27. Between the ceiling rafters, an open-cell 1/2-lb insulation spray-in foam was applied, followed by 150mm of polyisocyanurate board insulation above the sheathing. These measures create the well-insulated shell that minimizes the required size of the mechanical systems. Though this house is just a starter home for the young family, the finished product is built to last for generations. Having introduced new innovative features to the already existing heavy brick structure, this house will perform optimally for generations down the road.

while mutually benefitting from proximity. Research into the unit types allowed by the City of Toronto provided the raw material for the spatial organization of the project. A second suite, plus duplex, plus bed-sitting room gives the project the right mix of unit types to make it both economically feasible and allowable under the zoning by-law. Increasing density on the site while at the same time increasing the useable green space was a critical aspect of this project.

SKYGARDEN HOUSE NATIONAL WINNER

JURY COMMENTS: A renovation project that transforms a highly compartmented and energy intensive century old, single-family house into a bright, open and efficient residence. Organized around a central stair that also functions as a light well and ventilation chimney, the house achieves an impressive level of energy performance - close to Passive House standards. With green space provided at every level, the relationship between indoor and outdoor space is apparent everywhere, a remarkable achievement given the constrained site.

The renewal of this century old, 225 m2 single family residence on a small urban lot in Toronto transformed an old leaky house into a highly efficient three-storey home; one that takes advantage of active sustainable systems integrated with as many low cost passive sustainable strategies as possible. The project is part of an overall strategy to revitalize the urban fabric instead of razing it, creating livable environments for modern lifestyles in smaller footprints. Working within the existing shell, the Skygarden House uses design strategies to ‘expand’ the interior space without expanding the footprint of the house. The design provides outdoor living spaces on multiple levels to address the owners’ desire for a better connection to the home’s natural surroundings. Green space is increased with the installation of green roofs and the replacement of the paved backyard with a plant-filled oasis. Through careful spatial organization, passive strategies such as natural ventilation, passive cooling, daylighting, and solar gain were maximized. These were integrated with efficient active systems, such as in-floor radiant heating, high-velocity cooling, low-flow plumbing fixtures and high- efficiency lighting.

FORT ST. JOHN PASSIVE HOUSE Fort St. John, BC

1 British Columbia Regional Winner

South elevation

JURY COMMENTS: A highly commendable effort by a small and remote municipality to create a prototype residential building to the highest energy performance standards. One of the few singlefamily houses to be certified to Passive House standards anywhere in Canada, the educational opportunity this project represents is profound - and all the more remarkable because it is located in an area where the economy is dominated by the oil and gas industry. With a population of 18,000, the northern city of Fort St. John is the hub of British Columbia’s oil and gas industry. As the selfstyled ‘Energetic City’, Fort St. John recognizes that an excellent source of energy is conservation. This project is an exploration of what is achievable, even in an extreme climate, and serves as an example of the important role that municipalities can play

The site is a south-facing lot in a residential area that the City has designated for development as a sustainable neighbourhood. Passive Design strategies were used to maximize the thermal and environmental benefits through careful consideration of the thermal performance of building components and systems, minimizing heat losses in winter and heat gains in summer and maximizing energy efficiency. Energy conservation is achieved through the use of high performance triple-pane wood windows, a prefabricated wood structure with cellulose and mineral wool insulation, and ultra air-tight construction. This minimizes the required size of mechanical and electrical systems, which include heat pump hot water and space heating and a 3.5KW photovoltaic array. Passive House design demands large south-facing windows to optimize solar heating. The high-performance tilt and turn windows have an insulation value of R-9, eliminating draughts and cold spots. The Passive House design software permits detailed calculations of summer cooling loads, which have been optimized using solar shading and spectrally selective glass. A heat recovery ventilation system ensures a continues supply of fresh, filtered air from the outside at a minimum rate of 0.3 air changes per hour, providing indoor air quality that is far superior to that in a conventional home. The PV panels generate enough power to run an air conditioner without purchasing additional electricity. Air-source heat pumps with backup electric baseboards will emit 0.05 tonnes of GHGs per year â&#x20AC;&#x201D; which represents a 99% reduction relative to a typical single-family detached dwelling. The 9KW photovoltaic system is anticipated to cover up to 50% of the electric energy consumed over the year - the remainder coming from hydroelectric sources. The heating/cooling cost for the year is estimated to be $200-$400, which amounts to annual savings of approximately $1,000-$1,800 compared to an average house in this climate. The Fort St. John Passive House has achieved certification as a Passive House plus [PH+] through PHIUS. The building has an Energuide rating of 91 and an application for LEED Platinum certification is in progress. The project has been used to teach the local building community about Passive House construction and low-energy building design. The house is a living classroom with public open houses, brochures, signs, workshops and website information.

Atlantic Regional Winner

Dura House

Terence Bay, NS

JURY COMMENTS: An exemplary project that responds to the opportunities of its site, while respecting the rigours of the North Atlantic coastal climate. A compact plan, strategically placed thermal mass, airtightness 50% better than Passive House standard and a highly insulated building envelope make this a truly low energy house. Add to this the live/work configuration that will reduce transportation energy and the result is a compelling prototype which combines energy conservation, clever programming and contextual sensitivity. With its simple form, Dura House fits comfortably into the vernacular context of Terence Bay [1]. The fenestration responds to the orientation of each facade, but also to the opportunities for panoramic views [2].

1 2

Once a thriving fisheries-based community Terence Bay is transforming into an ocean-side suburb of Halifax, with the majority of residents commuting daily to the city. In this context, live-work residential configurations hold the promise of small-scale home enterprises that can enhance family flexibility, balance the demands of life and work, and enrich the local community. The built character of Terence Bay reflects its origins as a fishing community, retaining numerous traditional houses and private wharfs with fish shacks dotted along the rugged north Atlantic coastline. This site has a beautiful layered view to the south-west across islands and rocks to the Betty Island light house. To capitalize on this view the building had to be placed as close to the east property line as possible, and the living space had to be elevated 3.6 m above established grade. This immediately suggested a live-work configuration, in which 165 m2 of living space could be placed above 110 m2 of work and ancillary space. Fiberglass-frame windows have been strategically placed and sized to achieve solar heating, natural lighting, views, or ventilation. East and west elevations have large horizontal windows to catch sunrises and sunsets, with operable portions for cross-ventilation. Large operable horizontal bedroom windows preserve privacy, admit ventilation and day lighting and allow for flexibility of furniture placement. South-facing picture windows have no mullions, both for unobstructed views and higher performance.

Windows and doors are double-pane, argon-filled units with low-e coatings that vary according to orientation. A projecting balcony protects the south-facing windows from the sun for eight weeks either side of the summer solstice.

The balcony hangers are detailed to minimize thermal bridging. Ventilation is driven by a heat recovery ventilator that operates at 75% efficiency. It has an intermittent high speed booster eliminating the need for separate kitchen and bathroom exhausts. A ducted de-stratification fan operated by a cooling thermostat at high elevation in series with a heating thermostat in a lower bedroom run a low CFM fan that pulls hot air from the top of the house and circulates it to the lower rooms on the cooler north side of the building. Due to the poor quality and unpredictable supply of local well water, all domestic needs are met by rainwater collection. PH buffering takes place in storage tanks in the basement level ancillary room. Electricity and sunlight are the only two energy sources to the house. Thermal mass is used in the insulated concrete form [ICF] basement walls and hydronic radiant floor slabs to modulate temperature fluctuations. The air tightness of the envelope is 0.32 ACH @50 Pa; the roof achieves R60 with loose fill cellulose insulation, and the slab achieves R-16. with extruded polystyrene [EPS]. With its practical and economical approach to design and its flexible mixed-use program, this project continues the tradition of resourcefulness and resilience that has characterized Atlantic Canada for many generations.
