asked the Secretary of State for the Environment if he will, as part of research and development into solar heating, install experimental solar heating apparatus in Norman Shaw Building North.

Norman Shaw North building already has an adequate heating system, and installation of solar heating apparatus would not be economically justifiable. My Department, besides providing the Chairman for the Interdepartmental Steering Committee on Solar Energy Research and Development, works closely with the Department of Energy in these areas. It keeps in view the possible use of Government buildings as subjects for experimental trials of solar heating apparatus.
