“Every new piece of construction is to some extent a hypothesis and its performance in practice is the experiment.” Bill Bordass1 (p29)

On Thursday the 6th the RIBA, CIBSE and their other partners will be launching the revamped CarbonBuzz platform – the online platform that allows users to record both predicted and actual energy use over time.  But why measure these in the first place? Post-occupancy evaluation, whether it is of energy performance (as recorded on the CarbonBuzz platform) or any other aspect of a building’s performance in use, is founded on the two aphorisms, accredited to Lord Kelvin, “To measure is to know” and “If you cannot measure it, you cannot improve it”.

The evidence collected so far, from CarbonBuzz’s 400-odd sets of data, and from publications such as Jones Lang Lasalle’s recent “Are Energy Performance Certificates (EPCs) a true indicator of energy efficiency?” supports what was previously suggested only by anecdotal evidence:  that buildings are consuming more energy in use than they were predicted to – the ‘Performance Gap’.  You may have seen recent articles on the ‘Performance Gap’ in the AJ (25 April 2013) where they launched their ‘Bridge the Gap’ campaign.

A study that the RIBA will be publishing later in the summer that looks at the way that architects use information such as this – research-based information – in practice suggests that one of the key benefits for architects is in terms of innovation gains:  understanding how buildings, and the (often) complicated systems within them, perform so that they can create innovative design to improve built outcomes in the future.

Over the next year the RIBA’s Sustainable Futures Group will be encouraging RIBA members to upload data to the CarbonBuzz platform.  They will also be looking at the barriers that exist to increased post-occupancy evaluation (such as those identified by Bordass & Leaman,2 Lawson et al.,3 and Andreu & Oreszczyn4).  We expect that they will agree with previous studies that found that some barriers are largely perceived barriers only (e.g. cost5) but that others are more significant, but – hopefully – not insurmountable.

    An invite for Riba students interested in Sustainability.
    Eco art points, in Tuscany, propose some eco art experiences in the formes of summer camps. Very interesting for architect students are the stage ” installations in bamboo and wood with nights in Tree sleeping” ( 2-4 august, we repete 5-7 august). We work with colours, wood by the farme and we work to have objects, scultupre, installations, spaces in an estate on the start of the Mugello. With the bamboo we have experience about what are a tensostructure.The leit motif are the book ” Genius Loci” ( from C. Norberg Schulz). The stage are doing by a Florentine architect, specialiste in bio-architecture, by Inbar.

    bamboo, colour, wood, re-use, like first touch-experience in sustainibility.
