The British Council for Offices (BCO) has recently launched its Whole Life Carbon Footprint Measurement and Offices report. This deals with the issue of measuring the energy efficiency of buildings throughout their entire lifetime. This is a particularly hot topic given that new European legislation will require new office buildings to be designed with this ‘whole life’ approach to carbon emissions. Over the next few years, all private office buildings over a certain size will also have to display Energy Performance Certificates (EPCs), designed to strengthen commitment to CO2 reduction.
