All elements of a typical Superhome were considered in the design phase. Our goal was a healthy, energy efficient and sustainable home that performs exceptionally well without reliance on mechanical apparatus for air purification.
The Foreverbreathe wall system in this home incorporates wool insulation within a 140mm wall cavity. Magnum board was used as RAB board as well as internal wall board. The Foreverbreathe wall system is hygroscopic, enabling the wall structure to manage indoor relative humidity, maintaining as close to 50% RH as possible. Airtightness is 2.87 ach. The Foreverbreathe system comprises of natural, non-toxic products and has recently been endorsed by the NZ Asthma Foundation under its Sensitive Choice programme.
The Matapihi Protect system joinery consists of thermally broken timber windows with aluminium cladding on all opening sashes. All windows are triple glazed using high performance, low e coated and argon filled glass from Germany.
The home has a 6kw PV solar system with micro inverters mounted on the roof of the house. HVAC systems comprise of an integrated Mitsubishi Lossnay heat recovery unit, a Fujitsu ductedheat pump system and LunoseGo heat exchange units.
Lighting and appliances connected through the Econx system can be scheduled to make the most of the PV solar system, saving electricity.
The rainwater collection system uses twin tanks giving a capacity to collect and filter up to 10,000litres of rainwater. If the tanks become low the system automatically switches to town water supply.
The water purifier is specifically designed to kill harmful bacteria using a natural purification process that’s eco-friendly and chemical-free. It includes pre-filtration to ensure that particulate matter does not shield micro-organisms from the UV light.
At the time of writing the home is in the process of being audited for Homestar accreditation. Our vision is that this home will achieve 8 stars.
