Aging and outdated facilities, combined with higher food safety standards leading to rising production and operating costs, presented a need for a facility change for B.C. Tree Fruits Cooperative in the Okanagan region.

There are well-established best practices for delivering energy-efficient buildings on the path to net-zero. After site selection and building orientation, perhaps the most important consideration is the building enclosure or envelope. Next, the energy conservation measures (ECMs) are determined based on the envelope’s predictive energy-efficiency performance; they also include lighting, HVAC equipment, and controls. The last step for high-performance, low-energy buildings involves designing performance contributions of renewable energy technologies.

In London, Ont., a multi-residential apartment building built in 1970 was beginning to show significant signs of wear and tear on its exterior clay through-the-wall (TTW) brick, and owners had to develop a plan. Having already undertaken smaller localized repairs in the past, new water penetration issues on the upper, west-facing floors where the building is susceptible to driving rains, were cause to go in another direction.

Driven by the principles of high-performance energy (HPE) buildings through government, energy codes, and the green building movement, building energy designs across Canada and around the world strive to improve. The increasing focus on the implementation of energy-efficiency requirements, for both new construction and deep energy retrofits for commercial and public buildings, begins with envelope-first energy efficiency, reduced energy demand loads, and related greenhouse gas (GHG) reductions.
