The City of Ottawa wants all new subdivisions and larger developments to meet a new, stronger set of municipal green-building standards.

When city council approved tougher targets a few years ago for reducing greenhouse gas emissions and a road map to reach net-zero by 2050, city staff started working on standards aimed at one of two main sources of emissions locally: buildings.

It’s easier to design a new building to be energy efficient from the get-go than to retrofit older buildings, staff note in a report that goes to the city’s planning committee on March 10. 

City staff have crafted a “high performance development standard” for Ottawa, which they anticipate would take effect in a bylaw on June 1. They based it on the Toronto Green Standard, which that city has used since 2010, and say the provincial Planning Act gives municipalities the authority to roll out such rules.

During consultations some environmental advocates felt it didn’t go far enough, city staff note, while the construction industry felt they would be too hard to hit and would add costs. Delegations can sign up to five-minute presentations to planning committee next week.

The new rules would not apply to projects that need only a building permit, or small residential infill projects or low- or mid-rise buildings.

Larger buildings that require the city to approve a site plan would have 15 new metrics to meet, though. They would have to show a building would use only so many kilowatt hours of energy per year, for instance.

Other rules would lead to more bird-friendly glass, green roofs, and high-quality soil for street trees while not planting any invasive plant species.
