New retrofit methodology, and passive design: Spring SABMag In Brief

The Spring, 2022 issue of SABMag recently mailed. See the highlights below.
Clayton Community Centre: Open design process meets high performance and needs of users
By Melissa Higgs, Architect AIBC, FRAIC is a principal at hcma

The 7,000 m2 (76,000sf) Centre combines four aspects of the City of Surrey's community services - recreation, library, arts and parks. Community engagement played a crucial role in the design development and, from the start, the project was aiming for ultra-low energy performance and ultimately Passive House certification. 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 result is a reduction in energy consumption of 98% compared to the average performance of similar buildings in BC, and reduced carbon emissions by 98% compared to the same building built to ASHRAE standards. Photo: Andrew Doran.

Viewpoint: Dowel Laminated Timber: A step towards circularity in construction
By: Sigi Leibmann of International Timberframes

Dowel laminated timber (DLT) is a no-glue product that is 100% recyclable, reusable and does not produce contaminated waste. 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, with no glue or nails. In addition to stacked DLT panels there can be crossed DLT panels, a more environmentally responsible product than glue-bonded, cross laminated timber (CLT). DLT stores carbon in the walls and floors of a building; but has the added benefits that it is 100% VOC-free, recyclable, reusable and ultimately compostable. As such, DLT brings the concept of circularity from the macro scale of forest management to the micro scale of product manufacturing for the first time.

Parcours Gouin Welcome Pavilion: passive-active design brings urban beautification
By Maryse Laberge, Senior Principal at Beirtz Bastien Beaudoin Laforest (Groupe Provencher Roy).

Designed both as a visitor centre and as a showcase for environmental education, the pavilion integrates site preservation, potable water conservation, energy efficiency, renewable energy, local materials, and health and wellbeing. The Net-Zero project is certified LEED Gold which was achieved through a high-performance building envelope, high-efficiency mechanical and electrical systems, and an array of 120 photovoltaic modules capable of generating 31.8 kilowatts of renewable energy. The envelope assembly minimizes thermal bridging with continuous exterior insulation.

Building the future of nuclear through responsible waste disposal. Sponsored by Canadian Nuclear Laboratories
Plans have been laid for the construction of a highly engineered radioactive waste disposal facility in Chalk River, Ontario. 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 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. Read more …
The ReCover Initiative: Deep retrofit methodology cuts operating energy, reduces GHG emissions and upgrades ageing buildings
By Emma Norton, QUEST Canada; Nick Rudnicki, RSI Projects; and Lorrie Rand, Habit Studio
Conventional methods of performing deep energy retrofits are slow and expensive. 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. Read more …
Third & Hawkins Condo: Local residents band together to offer comfort and high efficiency to downsizers
By Mary Ellen Read, Northern Front Studio

Located in Whitehorse, the six-storey was intended as a sustainable, community-oriented residential building. To withstand the harsh winter temperatures and lack of sunlight, an enclosure-first design was critical to reduce energy consumption and improve both thermal performance and airtightness. The compact form minimizes heat loss while the 15-degree rotation of the building and significant overhangs maximize solar-gain in winter and solar-shade during warmer months. The building is equipped with a high-efficiency central ERV system, specifically a Dual-Core RG 2000, by Winnipeg-based Tempeff. Acting as the building's lungs, the ERV not only recovers heat, but also factors in humidity while supplying continuous fresh air supply and frost-free operation in this climate.
