Reducing Embodied Energy in Construction through Collaboration: Five Case Studies using 'bio-based' materials

摘要

In 2008 embodied energy in construction accounted for 17% of carbon emissions in the UK and is set to risernas a proportion of total emissions as other sectors cut their operational emissions. The use ‘bio-based’rnmaterials may be an important way to reduce the embodied energy of construction. A series of five casernstudies are presented using hemp lime, timber and strawbale construction. Typically problems havernoccurred due to lack of design guidance, inexperience and a lack of early contractor involvement. Arncollaborative culture and approach has overcome these problems and ensured that lessons learnt are takenrnthrough to future projects.
