Brief Summary:
The Housing Heating and Health Study has enrolled 409 households with ineffective heaters who have a child with asthma between 6 and 12 years
In the winter of 2005 houses were insulated and baseline measures taken of indoor temperatures nitrogen dioxide with more intensive indoor air quality monitoring in a sub-sample of 33 homes
Objective data are being collected on the households health and energy usage The households randomly assigned to the intervention group will have new heaters installed over the summer
Results will be available after the follow-up data collection in 2006

Detailed Description:
1 Introduction New Zealand houses are relatively poorly constructed and maintained for the temperate climate and most homes are heated to less than the WHO recommended minimum winter temperature of 18C Excess winter mortality is comparable to the levels in Portugal and Scotland The Groups previous Housing Insulation and Health Study has shown that insulating existing homes leads to a small but significant improvement in health and energy consumption but raised the question as to whether installing more sustainable heating could increase these gains
2 Study design
We have enrolled 409 households who use either plug-in electric heaters or unflued gas heating and where there is a child with asthma aged between 6 and 12 years In the winter of 2005 uninsulated houses were insulated and baseline measures taken of indoor temperatures in the living room and the childs bedroom and levels of nitrogen dioxide Intensive monitoring of indoor air quality is being carried out in a sub-sample of 33 homes All members of the childs family have filled out detailed questionnaires of their health and the heads-of -household have completed a questionnaire on the characteristics of the households energy usage Objective measures are also being collected of the households fuel bills the childs attendance at school and the familys health care utilisation
Households are randomised so that the intervention group will have their choice of new more efficient and sustainable heaters heat pumps wood pellet burners or flued gas heaters that heat more of the house and which emit no internal emissions installed over the summer In the winter of 2006 follow-up measures will be taken and then the control households will receive their choice of new heaters
