Project features
Materials
A lightweight steel structure minimises the requirement for concrete and all concrete that was used has a proportion of blast furnace slag content. Blast furnace slag has significantly reduced impacts from standard cement.
Forbo carpet flooring has been specified. Forbo complete Environmental Product Declarations on a large number of their products which tend to perform much better than industry average manufacturing techniques.
One very large contributor to the embodied impacts can be HFC blown XPS (extruded polystyrene) insulation. The alternative specification of Kinspan Optim R results in a relatively high saving in embodied carbon.
Operational Energy
Energy use accounts for approximately 73% of the life cycle impacts of Project Beagle (assuming todays grid emission factor). The use of roof mounted solar photovoltaics and innovative building integrated solar PV as well as advanced natural ventilation technologies have reduced impacts from operational energy significantly.
