1. Presentation by Lois Easton Beacon Pathway Limited �The problems that exist in the world today cannot be solved by the level of thinking that we were at when we created them� Albert Einstein (1879 � 1955)

3. Beacon�s Objectives To bring the vast majority (90%) of NZ homes to a high standard of sustainability by 2012 Every new subdivision and any redeveloped subdivision or neighbourhood from 2008 onwards to be developed with reference to a nationally recognised sustainability framework Challenge: how to bring about mass change in a short time?

4. The Scale of the Challenge 1.7 million homes in NZ(1 million pre-1979) 25,000 built each year 7,000 demolished

5. New Zealand�s Third World Housing Stock New Zealand�s housing stock has a reputation for being cold and damp. New Zealand has one of the highest levels of asthma and bronchial diseases in the world (1 in 6 people have asthma) Over a million of our houses were built before 1979 - the first full year when insulation was mandatory in new houses 30% of houses have an average living room evening temperature below 16�C The average winter bedroom temperature in pre-1979 houses is 13.2�C and in post-1979 houses 14.5�C.

6. Beacon�s High Standard of Sustainability Setting benchmarks at the house level for new and retrofitted homes Energy Water IEQ Waste Materials Benchmarks based on theoretical calculations verified by real life research data (eg BRANZ HEEP Project, NOW HomesTM) where this exists Benchmarks have been set within a context of affordability and future flexibility

7. High Standard of Sustainability � Draft Benchmarks The benchmarks set represent: a 25% reduction in energy use in new homes; a 15% reduction in energy use in existing homes; a 25% reduction in water use in both new and existing homes; Average indoor environment temperatures which meet the World Health Organisation minimum standards; adequate ventilation without excessive draughts; provision for waste minimisation during construction, renovation and operation of homes; consideration of sustainability issues in the choice of materials used for construction or renovation of homes.

8. High Standard of Sustainability Benchmark - Water

9. Now HomesTM Project NOW HomesTM hypothesis Using current technology and knowledge it is possible to build a home significantly more sustainable than current new housing for a price that is affordable to most New Zealanders Two NOW HomesTM have been built in Waitakere (Energy Climate Zone 1) and Rotorua Homes are occupied by �normal� families with no special training Homes are monitored against a Beacon�s High Standard of Sustainability

10. Waitakere NOW HomeTM 3 bedroom home House size 146m2 House built for $214,000 Construction waste significantly less than that produced by normal new home (2.5 tonnes vs 4 tonnes) 4 person household (2 adults, 2 children) Average income � and full range of appliances

13. Waitakere NOW HomeTM Have undertaken physical monitoring of key features (energy, water use, temperature, humidity) as well as monthly occupancy surveys Preliminary 12 month data in � 25% less energy use and 65% less reticulated water use per capita than homes in the surrounding area Occupants find the home warmer, drier and healthier than previous housing experiences -mean winter temperatures in bedrooms and living room exceed World Health minimum standards

14. Rotorua NOW HomeTM Is a collaboration with Housing New Zealand so affordability was a key consideration 3 bedroom home 141 m2 (plus concrete deck) Built for $180,000 Was tenanted in October and will be monitored for two years

17. Retrofit NOW HomesTM Project � Types of Homes 10 �ordinary� homes in Papakowhai, Wellington selected A range of house types with a range of different typologies (skillion roofs, conrete floors, suspended floors, cavity roofs etc) From an era which is know to be difficult to retrofit for energy efficiency, but represents about 10% of NZ housing stock

18. Papakowhai Retrofit NOW HomesTM Project Pre retrofit monitoring has been undertaken for 6 months Energy, Waste and IEQ retrofits in Feb-March Water retrofits in July Have modelled theoretical cost benefits and will compare with actual data Will monitor homes for 18 months post retrofit to capture �take back� in efficiency gains

19. Conclusions New homes are easily able to be developed which use substantially less resources in their construction and operation than �standard� New Zealand homes � at no greater cost Waitakere and Rotorua NOW HomesTM are being used to provide real life data verification of efficiencies able to be achieved Papakowhai Retrofit NOW HomesTM project seeks to verify benchmarks for retrofitted homes Technology is not the issue � what is needed is engagement by home owners with the performance of their dwelling and ways to improve it
