In 1973, during the first Arab Oil Embargo, I began to investigate alternative energy supports for architecture--ways to heat and cool buildings that did not rely on fossil fuels. Solar energy utilization was the most obvious solution, and was not new--having been in use around the world for more than thirty centuries. I found that bringing solar energy knowledge into a design process brought a new vitality and contemporary relevance to my architecture. Since then, passive solar architecture has been one of my passions. I believe that designing architecture that minimizes its dependence on fossil fuel is the most responsive contribution an architect can make to the global environmental crisis--including the carbon dioxide-driven "greenhouse effect". My own work and research convinced me that for most of the world, the external energy requirements for space conditioning of buildings can be drastically reduced by the low-technology use of passive solar energy.
