What Makes a Home Livable to You? The way we live is changing. As both an architect and a resident of Vancouver, I am regularly confronted with how our cities are changing through urban densification and shifting demographics, to accessibility and affordable housing. I think about the smaller units we are building as a response to this change, and I find myself considering livability as an important factor in the design of multi-family units.

1 Envelope renewal of the Belmont Building in Vancouver by RDH Building Science Inc. [http://bit.ly/2bm1G6L]. The varying vapour permeability of different insulation products, membranes, and other building materials adds complexity to wall assembly design [1]. [Photo courtesy RDH]


This education article is sponsored by: www.metlspan.com

Overview More stringent energy codes demand higher levels of insulation for external walls, and in many cases this means using exterior insulation, either as a substitute for traditional cavity insulation, or to supplement it. Additional insulation thickness and changes to the insulation location require additional consideration with regards to vapour diffusion and condensation control. The varying vapour permeability of different insulation products, membranes, and other building materials adds complexity to wall assembly design.


sabMag - FALL 2016

Some insulation materials, like mineral wool and fibreglass are vapour permeable, while others, like XPS, polyisocyanurate, and closed-cell spray foam are relatively impermeable. Energy codes are silent on this issue and building codes can be confusing in regard to the selection of exterior insulation and vapour diffusion control for walls. This article clarifies and provides guidance on vapour diffusion and condensation control in these new wall assemblies.


PERFORMANCE REDEFINED The use of insulated metal panels (IMPs) for building materials is on the rise. IMPs are an ideal solution to achieve the performance and durability necessary to compete in today’s demanding marketplace and comply with evolving energy codes. Metl-Span delivers high-quality, durable and energy-efficient solutions designed for unparalleled performance that stands the test of time.

60 Atlantic Avenue New life for an industrial building


The three-storey brick structure had undergone multiple alterations since its construction in 1898.

The renovation of 60 Atlantic Avenue in Toronto's Liberty Village is part of the ongoing transformation of this historic industrial zone in Toronto’s west end into a mixed-use neighbourhood. By Quadrangle

Originally built as a warehouse for St. David's Wine Grower's Co, it was taken over by the T. Eaton Company in 1922, and then in the 1990s it was converted into artists’ studios by Artscape, a not-for-profit urban development organization. Twenty years later, the exterior of the building was in rough shape and the interior was congested and convoluted. Outwardly, the aggregated effect of the many additions and alterations seemed to have compromised the integrity of the building, but more thorough investigations revealed that it still had great potential.

Design Objectives A comprehensive rehabilitation was proposed by the

The Mosaic Centre Edmonton office goes for triple play of net zero, LEED Platinum and Living Building Challenge

1 2 The Mosaic ‘Family’ comprises several employee-owned companies whose stated purpose is to create role model organizations that effect positive social change through business. In keeping with their philosophy, this 2,812m2 building provides the Mosaic Family not only with office space but employee amenities including a child-care facility, wellness centre, lounge areas, game rooms, a restaurant and an outdoor terrace. By Kent McKay The building also functions as a community hub and as an incubator for start-up businesses. Even those who simply rent a desk in the building have access to meeting rooms as well as the other employee amenities, while the restaurant, wellness centre and childcare are is open to members of the surrounding community. The project is pursuing both LEED Platinum and Living Building certification. The net zero energy requirement of the Living Building Challenge is a particularly ambitious target given Edmonton’s severe climate. This, and the realization of other performance goals required an integrated design process involving all members of the design and construction team.

Prefab form kits for frost-protected shallow foundations First published at Ecohome.net, which has a guide and videos for slab-on-grade construction. A slab-on-grade is a great alternative to a basement if you've got the space. Building with prefab kits make them easy and affordable. Rather than building wooden forms and taking them apart afterwards, a prefab slab-on-grade form kit uses shaped foam as the form itself. Once the top-rail metal fasteners are in place, no further bracing is required. This makes the installation much quicker by eliminating the steps of building forms and bracing them, then taking all that apart afterwards. Since prefab kits rest unsecured on the surface, they are also very easy to adjust for level and square. With a typical slab-on-grade [either kit or hand-built forms], the load of exterior walls is carried by the footing alone. An alternative option is a 'raft-slab' which has a uniform thickness.

Canadian form kit suppliers: Iso-Slab is a Quebec-based company that distributes slab kits across Canada. They provide EPS insulation forms, metal locking rail fasteners for the exterior edge, EPS board insulation for under the slab and exterior skirt insulation, all customized to each building design. Clients need to provide a soil sample and the company can provide stamped engineering documents Don't be put off by the higher cost of a kit over raw materials; the

The Canadian Precast/Prestressed Concrete Institute (CPCI), the National Precast Concrete Association (NPCA) and the Precast/Prestressed Concrete Institute (PCI) recently released Environmental Product Declarations (EPDs) in three key precast concrete product categories. The EPDs will allow architects, engineers, building owners, and other specifiers to better understand the environmental impacts of precast and prestressed concrete products. An EPD is an ISO-compliant and third-party verified, standardized and internationally recognized comprehensive tool for providing information on a product’s environmental impact. The precast concrete industry wide EPDs are now available for Architectural and Insulated Wall Panels, Structural Precast Concrete Products and Underground Precast Concrete Products. Download the precast concrete EPDs: www.sustainableprecast.ca | precast.org | pci.org

The members of CPCI, NPCA and PCI are proud partners of these two North American industry sustainability initiatives:
