There isn't a huge difference in price between high quality Australian, German or British double glazing products and the triple glazing offered by your company.
The problem was: because of the steel's temperature conductivity, there was a potential for mould problems caused by condensation, which would have rose up the wall. But it’s all taken care of now thanks to LAROS and Pro Clima: they sell truly environmentally-friendly and people-friendly products made for the New Zealand climate.
We recently installed a SANDEN Heat Pump. We chose SANDEN for a number of reasons including it being quiet. However, we were astounded at how quiet it actually is. You had to listen hard to hear from only a few metres. It is amazing.
Want an energy efficient house? When we finally found a builder prepared to tackle an ICF build, he sent us along to LAROS – and that changed our world! Andreas took 20 minutes out of his busy schedule to sit us down and tell us about ‘Passivhaus’ design – we never looked back. R6 insulation at roof level wrapped in a gortex shell, taped down to make it airtight and big, beautiful, TRIPLE glazed windows and triple sealed doors from Germany. The heat exchange ventilation systems keeps us warm in winter and keeps the heat out in summer. The SANDEN heat exchange hot water system and the 5KVA Solar system means power (and gas) bills are a thing of the past. We love our comfortable, economical, quiet (seriously) house. If you’re thinking brick veneer don’t sign until you’ve heard about Passivhaus.
We’ve been in the house for 2 months now, and through warm sunny days, gloomy days and overnight temperatures of -6 oC, the house has really shown that it is delivering on the promise. The temperature has not dropped below 19.2 oC (even with the freezing nights) and has stabilised at a comfortable 21-23 oC during gloomy days and cool nights. The higher temperatures, due to the solar gain on sunny days, are easily managed through opening the clerestory windows in the living room and tilting other windows throughout the house to manage a very comfortable temperature.
I just wanted to let you guys know the great news from some numbers I crunched last night. After the first full year since installing the SANDEN Heat Pump hot water service, my electricity consumption against the average of the previous 6 full years has reduced by 32% and my electricity costs have reduced by 51%. I suspect the difference between the consumption figure and the cost figure is due to the time of day, variation in charges, as well as the gradual lift in electricity prices over the last 8 years.
I purchased the SANDEN hot water system last year and am very happy with the results. As it is on off-peak tariffs, I can see it used only 120kWh (<$10) per bill in the warmer months and I saw no noticeable increase in off-peak usage in winter (maybe 250kWh/$20 per bill?). As I disconnected my gas, it has saved me a $550 p.a. gas bill. A great investment!
Four Pillars of Passive House Performance
Imagine a building that is:
Endlessly comfortable, yet has very limited needs for heating and cooling;
Fully solar-powered, omitting exposure to any energy price increase;
Accommodating to any architecture, while costing little more to construct;
Virtually maintenance-free, ultimately keeping its market value.
