The cost data gives ranges for materials and installation. Costs are based on the floor area of typical three- to four-bedroom dwellings. Costs vary in relation to scheme size, complexity of plan form, number and location of openings, floor to ceiling heights, thickness, size and composition of the panel construction.
A whole-life-cost analysis for structural wall panels is complex, as alternatives are not directly comparable. A comparison would require, as a minimum, the complete building structure and envelope to be modelled, including consideration of the comparative costs associated with manufacture, installation and in鈥搖se energy costs.
