High-rise buildings much more energy-intensive than low-rise
Office and residential buildings use more energy per square metre, the taller they are, according to new research from UCL.
Researchers at UCL's Energy Institute have found that electricity use, per square metre of floor area, is nearly two and a half times greater in high-rise office buildings of 20 or more storeys than in low-rise buildings of 6 storeys or less. Gas use also increases with height, by around 40%. As a result, total carbon emissions from gas and electricity from high-rise buildings are twice as high as in low-rise.
