On average, Commercial Buildings in Canada have shown little improvement in their energy balance over the last decade. A recent study assessing the progress made in designing high performance buildings in Canada i.e. consuming less than 60% of the Energy Code Base line showed a pleasant significant number of these buildings. The same study identified however only few buildings being close to net-zero and no existing net-zero commercial building. This paper wants to identify what progress have been made and what are the gaps to reach the net-zero energy target.
