Retrofit project - 89 City-operated arenas

General project information
The arenas retrofit project, part of the City's larger Energy Retrofit Program (ERP) began in 2004.

The arenas project included:

• feasibility studies to determine the practicality of various technical improvements
• engineering and design of technical improvements
• installation of new, energy-conserving technologies
• monitoring and verifying savings
• training City of Toronto staff to operate and maintain new equipment

The energy and water retrofits results in reduced operating costs, increased energy and water efficiency, facility improvements and reduced CO2 emissions. The retrofits provide improvements at 89 City-owned indoor and outdoor arenas. These improvements include:

• updating lighting systems
• providing advanced building automation systems to control lighting and ventilation
• installing heat recovery systems
• reducing drafts and leaks around windows, walls, and doors
• improving the efficiency of rink refrigeration equipment
• installing solar water heating systems
• upgrading heating, ventilation, and air conditioning systems
• correcting electrical system power factors

Cost and savings
The arenas energy retrofit project saves the City an estimated $1.25 million a year on utility costs and reduces the amount of greenhouse gases produced by the City's arenas by approximately 15 per cent.
