Book excerpt: The argument for low-cost, zero-energy, zero-waste architecture has never been timelier, while the mainstream has largely abandoned or neglected this agenda: in the UK the recent mandatory zero-carbon performance targets for new homes have been postponed or forgotten at a time when thousands of new homes will be built, and there is already a shortage of electric generating capacity. This book offers a forceful challenge to the current addiction to overconsumption of natural capital and energy, and provides workable, sustainable solutions for zero-carbon, zero-waste design.
