You may have heard that the heat island credits in the LEED® program are controversial here in Edmonton. The theory behind heat islands may be moot in a predominantly cold climate with eight months of snow cover. However, the credit is applicable for our short summers and there are more products tailoring to meet the requirements.
The Canada Green Building Council define a heat island as “the incidence of higher air and surface temperatures caused by the absorption of solar energy and its re-emission from roads, buildings and other structures.
“As a result, ambient temperatures in urban areas can be artificially elevated, resulting in increased cooling loads in the summer, requiring larger HVAC equipment and energy for building operations.”
High albedo materials – very reflective of solar radiation – answer the challenges of heat islands. We have featured this local manufacturer previously for their permeable paving stones, but now they have their SRI (Solar Reflectance Index) laboratory ratings and comply with the heat island effect non-roof credits. If you’re very creative and want to place these tiles on your roof, they can help you there, too!
For those looking for SRI-rated pavers for their local LEED® projects, Expocrete is Alberta’s local manufacturer that includes regional and recycled content in their products – and now high albedo content as well!
