This event was a collaboration with the Building Owners and Managers Association of British Columbia (BOMA BC).
The biggest source of future operational emissions from the building sector will come from existing, rather than new
buildings. Retrofits which target massive reductions in operational emissions are essential to address the climate crisis
and will need to be scaled up dramatically over the next decade. In British Columbia, electrification is the most
effective strategy to achieve significant emissions reductions. This event was the first in a six-part series focused on
deep emissions retrofits.
Decarbonization of a Commercial Domestic Hot Water System
Presented by Nicky Arthur, Colliers
Arthur Erickson Place is a 26-storey office tower, constructed in 1968 and located in downtown Vancouver. The
presentation focused on a project that included the electrification of the majority of the building’s domestic hot water
heating system with an air-source, hot water heat pump system. Colliers, the property manager of the building,
explained that this project was the first step towards decarbonizing the building as a whole, in line with the building
owner’s sustainability objectives. It also provided ‘proof of concept’ for the building owners around this specific
The project demonstrated the importance of aligning emission reduction goals with the building’s capital plan. It also
demonstrated that retrofits in older buildings are economically viable and play an important part in the transition to a

Achieving Deep Emissions Reductions in a 1968 Office Tower
Presented by Kenric Lee, Golden Properties Ltd.
The building located at 1177 West Hastings Street is also a 26-storey office tower in downtown Vancouver, built in 1968. In 2010, Golden Properties set a goal to eliminate the building’s GHG emissions and ultimately stop using gas entirely. They incorporated a decarbonization plan, centered on electrification, into their capital plan, and over the course of approximately ten years, they reduced their emissions by an impressive 70%, all while operating a fully occupied building. This is the kind of retrofit approach that B.C. needs – a studied, holistic and methodical approach of incorporating GHG-reduction measures into a long-range capital plan.

Deep Emissions Retrofit of a Multi-Unit Residential Building
Presented by Steven Fetterly, Impact Engineeering.
Semlin Gardens is a four-storey multi-unit residential building with 29 units. It was built in 1994 and is owned and operated by the YWCA Metro Vancouver.
Once the owner confirmed that parts of the building envelope and mechanical systems required renewal, they decided to explore cost-effective opportunities to combine GHG reduction measures with the renewal project.. As a result, they were able to achieve a massive reduction in operational emissions along with the renewal project.
Some of the electrification projects included:
Installing the heat pumps in the parkade allows them to take advantage of slightly warmer air (than outside) which in turn, improves their efficiency and operating range. The low-temperature space heating system was well suited for electrification as well, since most available heat pumps designed for hydronic heating provide low-temperature water.
An electrical capacity analysis confirmed that there was spare electrical capacity that could be used for the electrification projects without requiring an electrical service upgrade.
