What is one primary focus of the Ontario Building Code's provisions regarding renovations?

The primary focus of the Ontario Building Code's provisions regarding renovations is indeed on improving energy efficiency standards. This emphasis is part of a broader goal to reduce energy consumption and promote sustainable building practices. By enhancing energy efficiency, the Code aims to minimize the environmental impact of buildings, lower operating costs for homeowners and tenants, and support the province's climate change initiatives.

In the context of renovations, these provisions encourage the upgrade of existing structures to meet modern energy performance levels, which may include improvements in insulation, HVAC systems, and the use of energy-efficient windows and doors. This focus not only benefits individual occupants through reduced energy bills but also contributes to the overall resilience of communities against climate change.

Other choices may touch upon important aspects of building practices, but they do not capture the current priority of the Ontario Building Code regarding renovations as clearly as the focus on energy efficiency does.
