n important software tool that that aims to close the building performance gap is offi cially launched this month. Backed by CIBSE and RIBA, CarbonBuzz is
an online platform that encourages clients, contractors and consultants to share case studies, advice and performance data with their fellow professionals. Users keen to share knowledge and experience are free to upload
data and projects, while those nervous of revealing performance data have the option to upload information anonymously. The site, even in beta mode, has already gained traction. It is being piloted by local authorities, government portfolio managers and investors among others, and the supplementary planning document of Islington council is encouraging the use of CarbonBuzz for all projects. With 400 projects already uploaded, the scale of the performance
gap is becoming apparent – most buildings are consuming between 1.5 and 2.5 times the energy predicted at design stage.
As clients realise that poor performance is costing them money,
Consultant engineers can’t be expected to take on the risk of achieving building energy performance targets with no fi nancial incentives
they will look to building engineers to close the gap, and will expect better functioning buildings. More consultants will have to sign up to performance guarantees and face the risk of buildings missing their targets. Firms can’t be expected to take on the risk
of buildings achieving energy performance targets with no fi nancial incentive. The news that Mitie and Emcor are pulling out of the M&E sector because of low margins is a stark warning for clients (page 8). If they want buildings that perform, they will have to pay to ensure high quality engineering, and proper commissioning in the form of Soft Landings.
It is encouraging to hear of clients who understand the benefi ts
of delivering high performance buildings. Camden Council, for example, is predicting a saving of £500,000 on energy costs as a result of moving staff from old, energy ineffi cient sites to a brand new, low energy tower in King’s Cross. The building will include two swimming pools, partly paid for by the savings, so energy effi ciency can have a friendly public face too (see page 51 for details of the chiller specifi cation). BIM is the great hope for the better delivery of buildings. Starting on page 33 we look at some of the major issues for engineers, and examine how BIM is helping Grimshaw and Balfour Beatty deliver Heathrow Terminal 2B.
