1 Sustainable Construction : UK perspective and West coast experience

2 UK perspective 1 Since 1970s UK sustainability focussed on energy issues – future availability, cost Progress driven by legislation to practical limits Latterly, carbon is driver – global warming Sustainability now more broadly defined

3 UK perspective 2 Lesser concerns around materials Embodied energy / protecting resources Progressive greening often client driven Utilisation of ‘indicators’ e.g. BREEAM

4 Issues for UK architects Concerns about material use / wastage Costs of disposal Contractor issue? Egan and Rethinking Construction Reduction in waste – not reduction in resources?

5 Sustainable Construction : West coast experience

6 Energy a lesser issue – hydro power, low carbon Conservation of resources is cultural issue Preservation of natural habitat – lumber, water

7 West coast experience – Koo’s Corner High plot ratio Existing garage structure re-used 50% timber frame recovered timber. Floors reclaimed glu-lam beams Concrete with 50% fly-ash cement replacement

8 West coast experience – Koo’s Corner Exterior cladding composite of cement/wood waste Floor tiles re-cycled porcelain Rain water recovery, permeable surfaces

9 West coast experience – REI Store Re-use of site – re-cycled 76% materials Stone used involved no active quarrying Extensive use of timber in structure and finishes Early use of fly-ash in cement for concrete

10 West coast experience – REI Store No new timber greater than 75 x 200 Extensive use of glu-lam in structure Wall sheathing uses oriented stand board No finishes or low VOC

11 Sustainable Construction : Lessons for UK Architects Potential for greater use of timber and timber products Use of materials and components with re-cycled content Choice of finishes

12 Sustainable Construction : UK Architects need The case for sustainable construction A clear focus – what are the key sustainability criteria? Better information about materials and products and the impact of their use on the environment
