The aim is to deliver a carbon neutral home through acombination o energy ecient design and building practicesand on-site renewable energy supply so that its net orremaining total GHG emissions is zero.Ater the Zero Emission Demonstration House (AusZEH) is ondisplay and open to the public or a period o time, the AusZEHwill be occupied by tenants or approximately twelve months

while monitoring energy use and GHG emissions over thisperiod. The monitored demonstration home will consequentlyprovide the industry with live household energy usage reports.

The AusZEHs perormance will then be evaluated against otherhomes within the surrounding suburbs to gauge the success othe project and help identiy key areas or urther improvement.

This project has brought together industry and government in a consortium including:

KEy ENvIRoNMENTAL AND MARKET oUTcoMES:

Outcome 1: To use 70 per cent less energy than a traditional home.

About hal o Australias yearly GHG emissions rom buildings come rom energyusage in homes. This is 13 per cent o total GHG emissions rom all sectors, andkeeps growing everyday.

Outcome 2: To apply 8-star smart design and building principles developedor the AusZEH to mass market housing into the uture.

Outcome 3: To develop a simple and practical energy management andmonitoring system to enable households to make the right decision on energyconsumption and use.

Households dont really have a level o understanding on energy consumption, asdemonstratedbytheimbalancebetweenpeakandoffpeakdemands.Wewanttobe able to highlight what can be achieved and the behaviours that can be changedthrough smart house design, as well as smart monitoring o household usage.

Outcome 4: To use the data and insights gathered rom the monitoring systemand research project to identiy key areas o development and improvement orsustainable housing into the uture.

Achieving Zero Emission will be the result o the homes:

A house energy rating is an index o a buildings thermalperormance (i.e. heating and cooling requirements) orresidential homes in Australia.

DevelopedbytheCSIRO,theAccuRatesoftwarehasbeen designed to simulate the heating and cooling energyeciency o residential buildings.

WhenyouwalkintotheAusZEH,itmaylooklikeanyother new home. The dierence, however, lies within its

thermalperformance.Withan8starenergyrating,theAusZEH relies on the combination o the ollowing eatures:

wall and the ceiling doubleglazingtoallwindowsandslidingdoors insulatedwafepodconcreteslab(foundation)

Good orientation works on the basis o designing a homewhich takes advantage o its climatic and regional conditions.Good orientation increases the energy eciency o a home byreducing the need o additional heating and cooling, resulting indecreased GHG and lower energy bills.

The AusZEH is located in a climate that requires more heatingthan cooling to keep the home at a comortable temperature.The AusZEH uses the sun as a natural source o ree heatingduring the winter (a.k.a: passive heating). The smart designthereore makes the most o the suns warmth to heat the home

with the living rooms windows acing north. The windowstranser winter solar energy when the sun sits low in the sky andexcludes summer sun when its sitting directly above the house.

The northern windows are also shaded rom the hot summer sunusing an extendable awning and exterior blinds by Helioscreen.The exterior blinds are made rom a abric that reduces the sunsheat by up to 90 per cent.

Windowordoorglazinghasamajorimpact on the energy eciency othebuildingenvelope.Windowscanaccount or more heat gain or loss thanany other element o the home.

For that reason, several actors needto be taken into consideration such asbuilding materials, climatic conditions,the size and location o windows andthermal properties o glazing units.

Firstly, the balance between the size

o the windows and the extent o theinsulated wall is important as up to40 per cent o the energy used to heator cool a home can be lost through thewindows. The AusZEH windows have

been careully chosen to maintain year-round comort by reducing the needor articial heating and cooling andhence minimising energy consumption.

The AusZEH has been constructedwith timber windows which in turntransers less heat than other materialssuch as aluminium. These windowshave two panes o glass with a sealedgap which contains a substance thatremoves the moisture trapped in the airspace. These double glazed windows

reduce the amount o heat gain throughsummer and stop heat escaping romthehouseinwinter.Infact,thesewindows reduce winter heat loss bya massive 60 per cent!

Uncontrolled Air Leakage is a majorsource o energy loss that contributesunnecessary cost to the heating andcooling o many homes. The cracksand sources o leakage in a house thatallow conditioned internal air to escapeto the external environment need to becontrolled.The Air Leakage o AusZEH hasbeen minimised by the inclusion o simplesealing actions undertaken throughout thebuild&constructionphaseofthehouse.

Essentially, the use of high quality building

products and quality construction methodswith an eye for detail, have resulted in ahuge improvement in the homes leakageperformance. The resultant air leakageperformance of this house is approximately60 per cent improved in comparison to astandard5Starrated home.

10 11TraditionallyinVictoria,hotwatersystems have been the single biggestenergy consumer. However, overrecent years solar hot water systemshave been reducing this load.

This home utilises a twin fat panelsolar hot water system to provide upto 75 per cent o the hot water needsusing the suns unlimited ree energy.

Kitchen appliances can consume a loto power. The appliances at the AusZEHhave high star ratings, which mean thatthey consume less power than many otheir rival products.

Whenselectingyourappliances

make sure you check the star rating.Dishwashers, ridges, washing machinesand now televisions all have a starrating which lets you compare howmuch electricity and gas dierentproducts use. The more stars on thelabel, the more energy ecient yourhousehold appliance is.

The AusZEH has been equipped with whatat rst sight might look like normal halogendownlights. These lights, however, are inact energy ecient compact fuorescentlights that use 25 per cent o the powero halogen lights.

Many people mistakenly think that lowvoltage halogen lamps are low energylamps, but in act, each light consumes50Wwithanadditional10Wbeingconsumed by the transormer, comparedtothe15Wfromthelampsinstalledat

the AusZEH.

All energy and water usage inormation is displayed in the

house on a touch-screen interace, that can be accessedremotely via the internet or a mobile phone. The display will

show the occupants at-a-glance energy consumption o dierentappliances in the house (e.g. the air conditioner) or o speciczones (e.g. living areas or kitchen).

The occupants can drill-down on individual appliances orhousehold zones to display breakdowns o daily, monthly,or annual consumption patterns, costs and carbon emissions.

This inormation will help them adapt their behaviours to reduceemissions,andtakemaximumadvantageoftheon-sitePVs.

AZEH ha a pecially deigned energy monitoring and management ytem thatallow the occpant of the hoe to monitor and control:

power ed by individal appliance and in different zone of the hoepower generated by the on-ite PV and tored on-itepower drawn from the gridwater drawn from the mainwater drawn from the on-ite rainwater torage

The system can also estimate and display energy, cost andemission savings rom a range o energy-saving options, suchas reducing stand-by power, or more eective usage o heating,cooling and lighting systems in the house. A reporting engine isable to generate customised reports o power consumption ordierent timescales, household appliances and zones.

The system is able to intelligently control the main energy-consuming devices in the house, such as air conditioning, hotwater booster, and electric vehicle charging, depending on the

price o electricity at dierent times o the day, the o ccupantspreerences, and the availability o sol ar power rom the on-sitePVs.Itcanalsoautomaticallyswitchoffstand-bypowerindierent zones o the house at specied times. The intelligentcontrol options can be overridden by the occupants at anytime through the touch-screen interace.

The system allows energy stored in an electric vehicle, or on-sitebatteries to be used to power appliances in the house duringtimes o peak electricity demand or price.

The monitoring and control system in AusZEH is smart-grid

ready, which means that devices can potentially be controlledvia the main house smart meter according to the occupantsagreement with their electricity provider.

Inadditiontothecentraltouch-screeninterface,theoccupantswill also be able to interact with the household energymanagement unctions through a suite o new generation devicesunder development by Telstra, that will be specially connectedto the house energy management inrastructure. These includea set-top box, the wireless internet router, a portable tabletcomputing device, and the occupants mobile phones.

The AusZEH energy management system has been developedbytheCentreforTechnologyInfusionatLaTrobeUniversityinpartnershipwithCSIROandTelstra.
