asked the Secretary of State for the Environment whether he intends to encourage further solar heating experiments similar to the total heating of St. George's School, Wallasey.

The pioneering design of St. George's School, Wallasey, led to problems over inadequate ventilation, and to heat losses through the solar wall during sunless periods. The lighting system used for supplementary heating has also proved expensive. Current DOE work is directed towards the design and experimental development of new buildings of low energy consumption, taking advantage of such devices as solar collectors and solar heat storage.
