Green roofs bring energy savings - even in cold climates
There is some lack of consensus as to the benefits of green roofs in cold, heating dominant climates. There aren't a lot of studies done into this so the rule of thumb has generally been that green roofs provide their energy savings in hot climates where the demand is on air conditioning. That said, we've completed a study on the energy efficiencies brought on by our own green roof in Calgary... and it looks good! Despite being a heating dominant climate, we still saw appreci
