Housing alternatives for an ageing population in New Zealand: a resource assessment.
The growing demand for ageing in place requires effective housing solutions to achieve wellbeing and independence for those aged 65+. Research suggests that in New Zealand many in this age group live in large houses with two or more spare bedrooms. Furthermore, often being on restricted incomes, they do not necessarily maintain or heat these houses as much as needed. Therefore, this research aims to link different issues including the New Zealand housing stock (need for more age-friendly houses), ageing population (New Zealand population is ageing) and environmental issues (finite resources) in order to:
- Make better use of existing housing in New Zealand
- Provide a better quality of wellbeing and independence for those aged 65+
- Ensure older people have houses they can afford to heat and maintain
- Reduce resource use and consequently, the environmental impact of older people’s housing in New Zealand
The aim of my research is to reveal the housing options which have the lowest resource use and consequently are the more environmentally friendly and sustainable options but that are also most beneficial for the ageing population.
Two New Zealand housing types are being investigated (early 20th century villas with a central corridor and 1940-60s single storey state houses). Three designs have been produced for each house, ranging from subdivision (conversion to two smaller units), to having some shared spaces such as a guest bedroom, to private en-suite bedsitting rooms and all living spaces shared. To meet the needs of the ageing population, New Zealand level 3 Lifemark standards have been incorporated in all designs. The proposed conversions have been examined by an expert panel and in a survey of New Zealanders aged 55-85. All final designs will be subject to life-cycle energy analysis (LCE) and the results compared with new small houses. The outcomes of this evaluation will identify whether, in terms of resource and energy consumption, ageing in the community is a viable option of New Zealand.
