ABSTRACT
Since earlier editions of this book, new evidence has emerged that there are many secondary benefits to low energy design which help justify what is often an additional cost of sustainable solutions. Both in the US and Europe researchers have discovered that buildings based on more ecological approaches lead to social and economic benefits for the developer. These can be grouped under four headings:
Better life-cycle costing.
Improved productivity or performance in functional terms.
Better social relationships at a building and community level.
Enhanced image for the building and the organisation responsible for its inception.
