 The purpose of the lodge is a retreat building and it's also a place where our male summer staff live. We think it's probably part of the original camp along with the social hall, so late 1800s. There's rectangular nails in there, you know, so very old school. Passive House is a building standard. It's to make a building robust and highly energy efficient to use up to 70 percent less energy overall and 90 percent less energy to heat and cool. So basically you don't want any air moving in and out of the house that you're not controlling. The Passive House is an air barrier, so we're trying to create a completely sealed box. Think of it like a cooler. We want a completely sealed box with a bunch of uninterrupted insulation on the outside. So our air barrier, for example, here is the sheathing. It's all taped so no air can leak through the sheathing. Our roof is taped as well, and then a whole bunch of insulation gets bolted onto the outside. Think of it like a blanket that goes over the whole building. In a typical residential construction, you would have an equivalent opening of maybe about this big of all your holes in your buildings, with nail holes, everything. With Passive House, it's down to like this big, so net yet rare savings and cost to building the project. We've taken on the builder role to try to get our costs down the cost parity with conventional construction. There's a lot of interest in this type of construction and people want to be in these buildings. So it's a chance to live out our values. We're creating a structure that has very low environmental impact, very low abetted carbon footprint to it.
