Thomas Residence - Whatawhata / Hamilton
This house is located on an organic lifestyle block in rural Hamilton. The clients required a sustainable, highly energy efficient and low carbon footprint home that could also be a self-build.
To meet these requirements we designed a simple, single level timber framed structure and used exclusively untreated NZ grown timbers. We specified extremely well insulated and airtight wooden joinery made by Optimal Windows in Keri Keri, an Intello airtightness membrane system by Proclima. Knauf insulation that is made from recycled glass bottles was used to fill the over-sized wall thicknesses, tripling the min. R value required by the NZBC.
Just like the 'Passive House' a mechanical ventilation heat recovery system (MVHR) provides clean air and automatically controls the required air changes with close to no heat loss while windows stay closed. An additional heatsource (other that the sun) is not required.The building is collecting rainwater to cover the occupants demand, grey water diverted off and irrigates the vegetable garden. Food waste goes to the animals or into the compost bin.
In the near future a Solar Photo Voltaic system will be installed to provide the electricity needed to cover the buildings demand, adding to the zero energy house philosophy. This is a highly energy efficient, warm, healthy and sustainable home that was constructed with a Zero Carbon footprint.
