My father, Roger Kelly, who has died aged 72 of cancer, was an environmental architect, passionate about demonstrating how buildings can be designed to enhance the environment, not play a part in its destruction.
He spent five years in the 1980s in Cyprus designing buildings and helping to protect the Akamas area as a future national park, then became the director of the Centre for Alternative Technology (CAT) in mid-Wales from 1987 until 1997. After leaving CAT he worked on the Ecovillages project in
France and the EcoPeace village in Cyprus. Latterly he ran Energy Solutions, a company based in north
London helping local authorities to reduce energy use in their buildings.
