Supporting a transition to zero emission buildings requires relevant and enforced building and appliance codes and regulations. In Ontario, responsibility for creating and enacting building codes and regulations lies mostly with The Ministry of Municipal Affairs and Housing, as well as the Ontario Energy Board. However, a 2020 audit on reducing emissions in buildings found that neither of these entities focus on reducing building emissions, or climate change for that matter, as part of their decision-making processes. The Ontario Building Code must be strengthened to require that new and existing buildings not only reduce natural gas consumption, but transition quickly towards low- or zero-emitting energy sources. As noted by the Canadian Climate Institute, Ontario has yet to formally commit to zero carbon building codes or stringent appliance efficiency standards. As a result the majority of home heating stock will continue to come from gas. Climate adaptation measures are an equally important focus for building codes and regulations. Water, storm water and sewage infrastructure are the foundation for all buildings, whether in urban settings or in rural and remote communities. Building code regulations that ensure access to affordable, safe clean drinking water and, increasingly, green infrastructure for stormwater and sewage disposal need updating in the face of the drought, flooding and pollution challenges posed by the climate crisis. In the 2022 Value-for-Money Audit, the Auditor General of Ontario found that the Government of Ontario is failing to make adequate building code specifications. Many energy-efficiency and flood prevention devices are relatively inexpensive if installed at the time of construction, but are a costly renovation. In another retrograde use of Ontario’s building code, in 2019 the Ford Government deleted the requirement that all new homes have a ‘rough-in’ for an electric vehicle charger. Heat Pumps for Heating and CoolingAs EV’s are reducing greenhouse gas emissions in Transportation, Heat Pumps are a major emissions reduction technology in the Buildings Sector. Over 700,000 have been installed across Canada. Two OCEC Signatories have interesting videos of webinars on the topic and excellent educational resources: Heat Pump Resources for residential buildingsCheck your local community organisations devoted to facilitating energy conservation and efficiency for initiatives for the homes and buildings in your area - or use these as models to establish your own: Harbord Village Residents Association Pocket Change
