ABSTRACT

The challenge is to balance strategies, each of a very different nature, to fit the personal values and priorities of the home-owner or investor. Clearly a high priority is given to drastically reducing the amount of non-renewable energy a building needs, while at the same time improving comfort. If a building is to be promoted as ecological, then obviously there are other factors in addition to energy to address and the time horizon has to be extended to the lifetime of the construction.
