http://bit.ly/2RnaQ6Q - Hi my name is Bryan and I'm a director at ISMART Building Group here in WA. Welcome to the Perth Home Show. I'm gonna talk a little bit about what we do here at ISMART. Basically we're a building company here in WA. We also do manufacturing based on passive house principles. Passive house principles was basically designed in the early 1990's in Germany. It's based on building homes which are affordable to run. But not only that, they are healthy living environments. There's five main passive house principles. We started to start with the principles. The first one is thermal insulation inside your cavities in your walls. We start on an R3.5 and go up to an R4.5. In the walls, in your standard conventional brick construction, R-values are below one. So, straight away you're four times more efficient in your wall construction. Number two, we go through to thermal bridge free construction. Now, thermal bridge is where we have an influence from an external temperature to an internal environment. What we need to do is we need to eliminate that. Wherever we have a thermal bridge, be it a concrete construction, steel construction, whatever has a thermal conductivity from the external to the internal, we eliminate that by putting an insulation on the external side. Therefore, eliminating transfer of energy from the external to the internal. Next is number three, which is your windows. Your windows are one of your leading sources of heat loss and heat gain in your home. We import extrusion from Germany, manufacture it here in WA, with a double thermal brick on the frames. Once we get rid of the thermal bridging on the frame, we then turn our attention to the glass. We use double glazed, low weight argon filled glass. Which eliminates the heat transfer from external to internal. And then once we're eliminated that, we've now got a structure which is highly insulated we've eliminated our windows. We move on to air tightness. One of the main principles in passive construction is air tightness. We import membranes from Germany and we basically make all of the external walls, including the ceiling, airtight in the whole building. We then put a blower door test on the building and test the building to make sure it's airtight and what air loss we have. Once we've eliminated the air loss and we have an airtight building, we introduce cavities both externally and internally for services. Our services can run behind a battens plumbing, electrical, whatever services are required, audio visual, so that we don't have to penetrate the membrane. Now we have an airtight home that's highly insulated, with no thermal bridging, and we need fresh air. Okay here we have the heat recovery ventilation system from Stiebel Eltron. This is the unit that we put usually in the laundry. Small drop ceiling. It removes the odour and used air from the home and brings in fresh air. While it's doing so, it has an energy recovery system inside which basically brings in fresh air as it passes used air maintaining ambient temperature throughout the home 365 days a year for an extremely affordable cost. If you've got any other questions or you'd like to speak to any of the team here, we're at the home show all weekend if you'd feel free to come down say hello. Thanks very much.
