Project features
Materials
Lightweight cement has been specified to reduce the impacts of the floor areas. Carpets have been removed from the design allowing the tenants to make their own sustainable choices. Retaining the facade reduces the impacts for the external walls compared to a business as usual re-build.
Operational Energy
Energy use accounted for the majority of the impacts. The use of roof mounted solar photovoltaics and innovative building integrated solar PV has reduced impacts from operational energy.
Benefits of using Life Cycle Design
Using the concept of functional unit (impact / m2 of net letable area) was fundamental in the Life Cycle analysis. This is a vital information to be considered during the design process to maximise building performance and functionality.
