Championing best practice


C


an we ever achieve a low carbon future? This is not intended as a fl ippant or cynical question. Regular readers of the Journal will be well aware of the importance of a building’s


performance in the goal of cutting the nation’s CO2 emissions. There are two sides to the performance coin – the engineering side, which is open to testing, recalibration and renewal; and the behavioural side, which is far less predictable and controllable. The huge challenges presented by both sides, and their complex interrelationships, place a large question mark over whether we can meet those tough carbon targets. But, thankfully, around the country there are beacons of low energy


Technology by itself won’t signifi cantly reduce the carbon footprint of our buildings


good practice that light the way forward. The CIBSE Carbon Champion of the Year (see page 24) is a great example of how both sides of the coin can be tackled together. Bradford University is not only creating low carbon buildings that appear to be performing well (subject to current and future energy monitoring results), the institution is also working to instill the idea of sustainable living into its students, hopefully for the long term. It’s ‘Ecoversity’ strategy includes a sustainable module for each course and a new eco-learning centre; and it extends to areas such as university transport and embodied carbon. Perhaps this strategy offers some lessons when it comes to the challenge of persuading and


educating users of low carbon homes and offi ces to make them work as effi ciently as possible. Without appropriate usage, technology by itself will not signifi cantly reduce the carbon footprint of Britain’s building stock. Perhaps we need a ‘learning module’ for all new occupants of low carbon buildings. And how about an ongoing national advertising campaign along the lines of the old ‘clunk-click every trip’ TV advert? This, of course, is focused on the long term. Right now we need to promote tried-and-tested engineering solutions. As David Fisk argues in his CIBSE presidential inaugural speech (page 12), building services engineers have an opportunity to reassert ‘normal engineering’, which is about measuring and learning from the performance of real buildings, and delivering real low carbon solutions devoid of technologies that are little more than green bling. This ability to obtain fi rm knowledge about what works, in both engineering and behavioural terms, should give us good grounds for optimism that, despite the challenges, we can signifi cantly cut our buildings’ carbon footprint.
