Redefining zero carbon

29 June, 2008

‘Our proposed definition recognises off-site renewables could play a part and also gives a big boost to community-scale technologies. This would have the added benefit of enabling much needed carbon reductions in the existing stock by enabling the distribution of low- or zero-carbon heat through district networks.
The full report is available on the UK-GBC web site.

‘The solutions we are pointing to are designed to ensure energy-demand reduction always comes first and on- or near-site renewables should be the focus for meeting energy needs.

First-year undergraduates from Southampton university recently attended a Constructionarium to give them a taste of what a career in engineering and project management has to offer The group of 80 students was hosted by Faber Maunsell and Laing O’Rourke for this hands-on week-long residential construction experience, which is designed to be part of a 21st-century engineering education linking the world of academic theory with contractors and consultants from the industry. They were split into four teams to design and build scaled-down models of real-life construction projects.
CIBSE’s new president believes it is time for the institution to position itself as the leading authority on the built environment.
Rapidly, and seemingly inexorably, rising fuel costs gave added meaning to the recent CIBSE Conference on ‘Sustainability — niche to norm’ in Gateshead because, quite simply, reducing fuel bill reduces carbon emissions.
