From the outset, sustainable principles guided the design of this large hall that provides maximum headroom for a significant collection of historic aircraft. An admirable economy of structure, achieved by means of Laminated Veneer Lumber (LVL) clear-spans of impressive extent, has allowed for the generous provision of naturally ventilated space. The specification of locally produced LVL resulted from a comprehensive life-cycle building analysis, including empirical research into relative carbon balance and the embodied energy of various structural options. This rigour is consistent with the Architect’s thorough-going sustainable approach to a project on a site requiring and receiving careful environmental monitoring.
