§ Mr. Wingfield Digby
asked the Secretary of State for Education and Science what instructions she has given to local education authorities to modify designs of new schools so as to reduce glass and thereby produce economies in heating.
§ Mr. Raison
None. A general reduction in window areas in schools would not necessarily save fuel, as additional electric lighting would be required to supplement the lower level of daylight. Local authorities are aware that the cause of fuel economy is better served by designing schools with improved thermal insulation in walls and roofs, and by ensuring that the heating controls in buildings operate effectively and that electric lights are not used unnecessarily.
