Healthy Building: Evolving Green Building Tech with B+H’s Lisa Bate

Lisa Bate, representing B+H Architects, is a very active member of the Better Places for People Steering Committee and this profile really shows her dedication to healthy buildings.
When B+H Architects’ Lisa Bate arrived in Shanghai in 2012, the Toronto architect set out to help improve the green standards of the Chinese development industry. Bringing a wealth of international experience to a market not known for its ecological and architectural standards, Bate—elected as Canada’s representative to the World Green Building Council—worked to implement sustainable design principles and green building technology in a part of the world that western eyes often see as lagging behind in environmental standards.
In returning to Toronto, however, it’s Bate’s foreign experience that now helps guide some of B+H’s Canadian practices. “Ironically, in this case it’s the east leading the west,” Bate tells us, explaining the Chinese Gigabase system that comprehensively tracks building and material performance. Together with its associated RESET app, the GIGA database “provides a huge collection of raw data,” with the compiled information facilitating a more thorough overview of buildings and individual materials.
“The RESET app allows developers and architects to monitor air quality and environmental conditions—including ambient temperature, CO2, and humidity—in buildings real-time,” Bate tells us, “while the [GIGA] database provides a comprehensive listing of individual materials and their energy performance.” Launched in 2009, the cloud-based material management software also includes the RESET app, which analyze the environmental performance of buildings in real time.
Created by a team of architects who struggled to improve green building standards in China, the GIGA system—which includes the Gigabase and the RESET app—has made implementing better standards easier by providing a more comprehensive data pool. Launched “as an open source database listing the greenest materials available in China’s construction marketplace,” the project’s official website lists a wealth of green building projects made possible—in part—by the software, which has since received international support from the Clinton Foundation.
In the Canadian context, Bate argues that the RESET app can prove particularly impactful. “Typically, the environmental health of buildings isn’t as closely monitored once occupancy begins,” Bate explains, describing industry standards that analyze indoor environmental quality in the “flush-out” period that follows construction completion but precedes occupancy. “With RESET, though, environmental conditions are tracked over the long-term, giving us a better idea of how buildings age and what kind of environmental concerns develop over time.”
“Here in Toronto, though, our outdoor air quality is generally very good, so the circumstances aren’t the same. In China, it’s about keeping the bad air out, but here, the bad air is typically inside,” Bate explains, describing the “sick building syndrome” that is increasingly becoming recognized as a health hazard. Using RESET, Bate notes that the impact of every change or retrofit made to a building can be effectively tracked, giving architects, developers, property managers and tenants a more transparent overview of long-term conditions.
Now back in Toronto, Bate characterizes our green building industry as an increasingly assertive leader in innovation. “In many cases, it’s the industry leading the way and working to innovate. We don’t have a culture of just responding to meet the green standards that are mandated. For much of the industry, the benchmark that we aim to set is higher. We don’t get things handed down to us. We hand them up.”
While Bate touts the wealth of data provided by the GIGA software as an important tool, “it’s ultimately just that, a tool. What really matters is how we use that information and what we try to learn from it, how much we strive to innovate… What really matters is what we choose to do.”
