anything, can have signifi cant unintended consequences. Large portfolio holders in particular are taking notice of commercial risks associated with new, supposedly low carbon buildings and refurbishments falling short of performance expectations. The issue of the performance gap is so fundamental that the RIBA Sustainable Futures Group and CIBSE Benchmarking and Energy Performance Groups are campaigning for the disclosure of data and targeting measured energy use rather than more legislation on relative improvements. The professional bodies want their members to share lessons learned from monitoring completed projects via the RIBA/CIBSE crowdsourcing platform,
CarbonBuzz.org. Both institutions are also spearheading

here is growing evidence that current legislation is not delivering the expected reductions in the actual energy use of buildings and, if
use exists, and to help close it by publishing evidence, advice and case studies. We see it as ‘disruptive technology’
created by young professionals recognising that legislation is not delivering real-term carbon reductions – nor is it providing much-needed data and evidence to underpin investment in low energy measures. Being social media savvy, they opted for ‘crowdsourcing’ – offering built environment professionals a simple and quick way to upload, share and benchmark building energy use data. Most of the 800 or so members manage their data and benchmark it anonymously, but users can showcase their expertise by publishing projects and data. A key feature of the website is that
energy consumption is displayed as an easy-to-read ‘energy bar’ that shows annual consumption in either kWh/m2
/yr or kg CO2/m2 /yr equivalent. The bar can display
either fuel consumption or, where the data is available, energy use apportioned to heating, cooling, auxiliary power, lighting and small power loads. The website has been piloted extensively by local authorities, government portfolio managers, developers, landlords, investors, architects, engineers and facilities managers.
