In Alberta right now, the energy prices are really low, including the natural gas and electricity prices. They both are at historical lows. Now a single payback for a net-zero home is about 75 years or so. From an economical point of view, it's not that attractive actually. But we need to consider that net-zero homes are highly energy efficient homes and also provide a more comfortable living environment. There are now a lot of homebuyers...and we are also kind of marketing the net-zero homes and highly energy efficient homes from that perspective.
