As part of an aggressive action plan designed to reduce greenhouse gas emissions by 80 per cent by 2050, The City of Toronto’s Environment and Energy Division has established The Eco-Roof Incentive Program.
Under the Eco-Roof Incentive Program, Toronto property owners that upgrade their current roof, or build a new roof using cool roofing materials are eligible for a grant of up to $50 000. Existing and new residential, industrial, commercial, and institutional buildings are eligible, and if approved, will receive $2-5 / square metre up to a maximum of $50 000.
What is A Cool Roof?
A cool roof is a roof that strongly reflects the sun’s UV rays and also cools itself by efficiently emitting radiation away from the structure. A cool roof literally stays cooler than asphalt, steel, or other conventional roofing materials and reduces the amount of heat conducted to the building it covers. If a building does not have air conditioning, this keeps the building cooler and a more constant temperature. Conversely, for a building that has air conditioning, a cool roof will reduce the output needed from the air conditioning unit and reduce energy consumption.
What is Solar Reflectivity and Thermal Emittance of a Cool Roof?
Cool Roofing Materials
Because of today’s technologically innovative colour coating systems such as Kynar 500® and Hylar 5000®, a cool metal roof need not be white. There are many aluminum cool roofing products that use darker-colored pigments that have a high Solar Reflectivity Index (SRI). Additionally, A cool roof need not be a flat or low-sloped roof. Cool aluminum roofing panels come in a wide variety of architectural profiles to suit any style of home or commercial application, giving property owners the best of both worlds in terms of style and performance.
