Air-conditioning systems consume a lot of energy. We all know that high energy use means carbon emissions – which is bad! Indeed, the trend for carbon management strategies (not to mention the now-live CRC Energy Efficiency Scheme) clearly shows that it just is not 'cool' to be a high energy user. Yet air-conditioning is often seen as a necessity, in order to cool buildings and to maintain a comfortable and productive working environment. So there is the dilemma: be an evil high energy user, or have a hot, sweaty building that is unpleasant to work in! The good news is that businesses could actually reduce emissions and save on fuel bills simply by better management of air-conditioning use. The even better news is that it is a simple, low-cost solution. In this programme, we look at the 24°C Project which was undertaken by British Council for Offices (BCO).
