Developer SekisuiHouse is building the company’s first net-zero-emissions home in Australia, Shinka House (Japanese for “evolution”), at TheHermitage estate at GledswoodHills.
The home is being built now. It’s expected to get a thermal comfort rating over eight stars – two more than the national Australian standard. It will reduce water consumption and greenhouse-gas emissions by more than 40 per cent below NSW minimum targets.
Sekisui has already built more than 35,000 net-zero homes in Japan and has been at the forefront of research and development in this since 2008, when its zero-emissions house was featured at the Hokkaido Toyako G8 summit in Japan.
Sekisui’s Craig D’Costa said: “Promoting highly-sustainable housing solutions is a foundation principle ingrained across our global operations. With thousands of homes already built in Japan, it made sense to extend this to buyers in the company’s flagship Australian community, The Hermitage at Gledswood Hills.”
The house has minimalist PV and battery storage, air and acoustic balancing, active and passive climate-control, double-glazed thermally-broken aluminium windows and doors, geothermal augmented airconditioning, energy and wellbeing automation, multi-functional spaces, low-maintenance external finishes and low VOC paint and surface coverings.
It has a functional and comfortable living environment using minimal energy, a healthy ecosystem with consistent indoor temperature and adaptable living spaces to suit families' life-cycle stages.CRAIG D’COSTA, General Manager, Sekisui House
“Benefits are a functional and comfortable living environment using minimal energy, a healthy ecosystem with consistent indoor temperature and flexible living spaces adaptable to suit different family types throughout life-cycle stages.”
Covering 307 square metres over two storeys it has several living rooms and is designed for multi-generational living. There is internal and external zoning to suit family needs. It’s due to be completed early next year.
Japan, Europe, the UK and USA recently introduced programs to promote net-zero-energy homes to reduce carbon emissions. Japan is targeting all new houses to be zero-energy by 2030. The California government has set a goal for all new homes to be net-zero-energy by 2020.
Sekisui has invested A$2billion here, delivering nearly 10,000 homes.
