The Side by Side in use Monitored Performance of two Passive and Low Carbon Welsh Houses

By Ian Ridley, Justin Bere, Alan Clarke, Yair Schwartz, Andrew Farr

On Sunday, some of the UK's leading building performance experts joined Dr Wolfgang Feist and Witta Ebel of the Passivhaus Institute, visiting some of our latest domestic and non-domestic Passivhaus projects in London. The purpose of the visits was to review the last 12 months of data analysis and inspect the live data that is being produced, in order to check if Passivhaus is working in the UK climate.

At the end of its first Winter, these results are better than we would have dared hope for. Mayville Community Centre is also performing better than design, although it should be noted that these results are preliminary as not all the offices have been fully occupied. 

A full report will be published soon.



From time to time there are priceless email debates between members of the RIBA Sustainable Futures Committee. These debates are often concluded by wise words from Bill Bordass with illuminating attachments from his archives. One day someone must produce a book bringing together in one place all of Bill's written and professional work. 

A recent debate concluded on the topic of 'New Professionalism' and I have attached, with Bill's permission, pdfs of a written document and three slide shows of huge importance to all of us working in the construction sector.
