Case Studies

Capital Park (Jawl): Hot Water Heat Pumps

Capital Park was originally designed with two condensing gas hot water boilers, coupled with a 250-gallon storage tank. One of the gas hot water boilers failed prematurely. As with all major equipment replacements, Jawl wanted to evaluate like-for-like replacement with alternatives that would support their greenhouse gas and energy consumption reduction targets. Accordingly, they conducted an analysis comparing the conversion to CO2 hot water for the building with the straight replacement of the gas-fired hot water tanks.

Their analysis showed the cost of converting to three Sanden CO2 heat pumps was approximately 35% higher than replacing the two condensing hot water tanks. However, including lifecycle factors, GHG and energy consumption goals demonstrated a positive business case.

Capital Park (Jawl): Solar Photovoltaic

Owned by Concert Properties and Jawl Properties, Capital Park is a mixed-use development that includes office, commercial and residential uses. 525 and 545 Superior St are both five-storey buildings with office use on floors 2-5 and ground floor retail. Both buildings are LEED Platinum Core and Shell Certified.

The Capital Park solar photovoltaic system is a 251-panel, 114 kW system, with an expected lifespan of 40 years. To date, the system’s performance has exceeded expectations and is expected to produce 112,000 kWh annually. Read more here.

Bay Centre

Located in downtown Victoria, Bay Centre is a 47,500 m2, four-storey enclosed mall that includes retail, parking and food services. The building was constructed circa 1989 and currently receives up to 6.5 million visitors per year. Between 2011 and 2019, the mall achieved a 29% reduction in both energy consumption and overall greenhouse gas (GHG) emissions. Property manager Cushman Wakefield Asset Services implemented a series of measures to achieve these reductions. 

This study addresses a key challenge for the building – that it lacks a centralized heating system, meaning that custom opportunities would need to be uncovered to achieve deep energy and carbon savings. Read more here.
