Mainstreaming High Performance Net Zero Energy Housing
Josh’s House and Beyond Dr Josh Byrne GBCA Webinar 4th April 2017
PRESENTATION OUTLINE • • • • •
Josh’s House design and performance targets Construction method and materials Energy and water efficiency features Performance results Overview of related and future research work
JOSH’S HOUSE Property Layout
Climate Responsive Design
DESIGN TARGET Energy Use
• 10% of the energy used in a typical Australian new home • Save over $2,000 a year just in energy costs
DESIGN TARGET Water Use
• 40% of the scheme water of a typical Perth home
DESIGN TARGET Greenhouse Gas Emissions
• Emit less than 10% of the GHG normally emitted by Australian dwellings
CONSTRUCTION Thermal Mass
Insulation – Walls
Insulation – Roof
Insulation – Ceiling
Insulation – Windows
APPROPRIATE LANDSCAPING Seasonal Shading & Cool Surfaces
SOLAR ENERGY SHWS, PV’s + Battery
WATER MANAGEMENT Internal Water Efficiency
Rainwater Harvesting
Greywater Diversion
Stormwater Infiltration & Abstraction
PERFORMANCE MONITORING

Smart Metering & User Feedback
Internal Temperature – Summer (Typical Week)
Internal Temperature – Winter (Typical Week)
Electricity Use & Generation
Gas Use
Operational GHG Emissions
Electricity Use Profile: Typical House
Electricity Use Profile: High Performance House
Electricity Use Profile: High Performance House + Solar
Electricity Use Profile: High Performance House + Solar + Battery
RELATED WORK
YEAR 1 Demonstrate that high performance, net zero energy housing is readily available to the volume market via a real-life build.
YEAR 2 Showcase other examples from around Australia to generate national interest.

YEAR 3 Investigate the impact of resident behavior vs design on household energy use and carbon emissions.
FURTHER WORK Challenge Perceptions (Barriers) • Zero Energy Homes are expensive and impact affordability of new homes. • The market is not interested.
Mainstreaming High Performance Housing (CRCLCL RP3009e1) • Work with property developers and builders to deliver three HP ZEH display homes around Australia. • Establish an agreed construction industry position on the construction cost of HP ZEH volume market homes. • Undertake an assessment of the market potential of HP ZEH homes. • Foster heightened awareness of the accessibility (cost and capacity) and market interest of HP ZEH features.
