B
The behaviour of a building's users may be at least as important as its design when it comes to energy use,according to new research from the UK Energy Research Centre(UKERC).The UK promises to reduce its carbon emissions(排放)by 80 percent by 2050,part of which will be achieved by all new homes being zerocarbon by 2016.But this report shows that sustainable building design on its own-though extremely important-is not enough to achieve such reductions:the behaviour of the people using the building has to change too.
The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency(效率),which instead focus on architectural and technological developments.
"Technology is going to assist but it is not going to do everything,"explains Katy Janda,a UKERC senior researcher,"consumption patterns of building users can defeat the most careful design".In other words,old habits die hard,even in the bestdesigned ecohome.
Another part of the problem is information.Households and billpayers don't have the knowledge they need to change their energyuse habits.Without specific information,it's hard to estimate the costs and benefits of making different choices.Feedback(反馈)facilities,like smart meters and energy monitors,could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use;some studies have shown that households can achieve up to 15 percent energy savings using smart meters.
Social science research has added a further dimension(方面),suggesting that individuals' behaviour in the home can be personal and cannot be predicted-whether people throw open their windows rather than turn down the thermostat(恒温器),for example.
Janda argues that education is the key.She calls for a focused programme to teach
