Better Buildings Ottawa

Benchmarking and auditing

Benchmarking programs mandate owners of buildings over a certain size to measure and publicly report their performance data such as energy use, water use and greenhouse gas emissions. Studies have shown that benchmarking programs can lead to savings of two to three per cent per year. Benchmarking programs set baselines, diagnose performance, improve energy literacy and provide indicators for measures of success.

Ontario’s Energy and Water Reporting and Benchmarking (EWRB) initiative requires buildings 100,000 square feet and larger to report their energy and water usage annually.

The City is considering a benchmarking and auditing program for buildings 20,000 square feet and larger. Participants would be asked to publicly benchmark their energy and water consumption annually through Canada Green Building Council’s Disclosure Challenge(External link). In exchange, participants will receive subsidized thermal energy audits, energy scorecards, and Energy Star certification and tailored information sessions on energy and emission reduction opportunities. The program would be free to join. We hope to launch this program in October. Participants will be eligible for support once they have disclosed their energy and water consumption

Marketing, education, and training

To help the building sector overcome barriers such as lack of knowledge, time, and motivation to undertake retrofits, the following marketing, education, and training programs will be developed:

• A retrofit portal that includes energy performance comparisons to similar buildings, information on pathways to meet energy performance thresholds and links to incentive programs
• A certification and verification process for accessing City programs that tightens overtime and excludes poor performers
• Workshops, training programs and information packages on retrofits for different building types
• A registry of experienced renovation contractors
• A retrofit support service to provide advice on programs, requirements, rebates, performance issues and connect building owners to appropriate service providers
  
  

Economic tools and coordination

To help the building sector overcome financial barriers to retrofits the following will be considered:

• Providing financing options for deep energy retrofits that stay with the property
• Reducing capital costs through the coordination of bulk retrofits and supply chain supports
• Launching a Community Improvement Plan to offer incentives tied to carbon reductions
• Offer subsidisation of relocation costs for tenants during major retrofit activities
  
  

Regulating disclosure, energy audits, and emissions performance

The City will explore options to mandate emissions performance for all buildings over a certain size such as:

• Requiring buildings to benchmark and disclose their energy and emissions annually
• Requiring American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) Level II energy audits and/or recommissioning every five years to ensure building owners are aware of energy and emission reduction opportunities as well as embodied carbon, resiliency and health implications
• Requiring buildings meet emissions performance standards that become more stringent over time
  
  

Senior government engagement

While the City of Ottawa has many opportunities to directly support and require the decarbonization of existing buildings, there are a number of market signals and responsibilities that lie outside its control. The City can leverage its position as the capital of Canada and through collaboration with other municipalities, to engage with other levels of government and accelerate our collective ambition.
