|The two plans are fairly similar to start with; both have the same end goal of reducing green house gas emissions by 80% by 2050. Both plan to use new regulations to improve the efficiency of both mechanical systems and envelope.|
However, there are significant differences. The COV’s plan is to require renewable energy in all new buildings by 2030. NYC’s plan is to aggressively require retrofitting existing buildings by 2030. While there are fossil fuel caps in NYC’s plan, COV’s plan is extreme by only allowing renewable natural gas to be used.
From a HVAC perspective, there is a much wider range of mechanical systems available if natural gas is an economical perspective. In a study done in 2014, 58% of the energy used in buildings comes from natural gas use. There is going to be a significant amount of retrofits required to “electrify” buildings so that they can comply with the 2050 renewable energy mandate.
In the next 10 years, new building construction in the City of Vancouver is going to be dominated by heat pump-type systems that can meet performance requirements, without using fossil fuels.
