David Fujiwara Architect


This project for the Ontario Association of Architects Headquarters (OAA) involved a 22,300 square foot renovation. This facility was adapted to meet the goal of the 2030 Challenge by heating and cooling the building without burning carbon. Work included replacement of major components of the existing HVAC system and addition of new HVAC components, exterior improvements and interior alterations that improves occupant comfort and indoor air quality while transforming the interior office layout.

The building will produce enough electricity and heat from solar PV and thermal panels and underground heat to achieve net-zero energy on an annual basis. This compensates for any expended electricity and eliminates the use of fossil fuels. The use of triple glazed electrochromic glazing, fans and pumps and high efficiency lighting contributes to reduced energy consumption.

This ground-breaking project and the aim of the OAA to lead change to meet the 2030 Challenge is featured in the April 2020 issue of Canadian Architecture as well as several articles in the Daily Commercial News over the past few years. This project has also received a LIT Lighting Design Awards in the category of Net Zero Lighting.
