Our Ironstone building in Burlington is an energy efficient building that uses geothermal heating and cooling. It also uses energy star appliances, green roofing, low flow chrome faucets, etc. If we were to go for LEED certification, we would have about a silver rating. However, we do not subscribe to any of the Energy-Efficient Building Programs described on CMHC’s website. Purchasers however can apply for a refund using the Energy-efficient Premium Refund Form.
