What is the relationship between built form and energy use in dwellings

摘要: Abstract Energy is used in dwellings to provide four services: space heating, hot water, lighting and power appliances. This paper describes how the usage of energy a UK home results from complex interaction between built form, location, energy-using equipment, occupants affordability fuel. Current models with standard occupancy predict that use will be strongly related size but surveys real homes show only weak correlations, across all types dwelling. Recent research has given us insights into factors including preferred comfort, ‘take-back’ thermal efficiency improvements, patterns electricity use. Space heating on downward trend low new dwellings. for lights appliances, which weakly increasing. Strong legislation, combined low-carbon technologies, needed counteract this trend. Future challenges discussed include increases prices climate change mitigation efforts, are likely improve existing stock. Challenging targets now place housing move towards or zero carbon standards. In longer term, demand less energy. Alternatives gas increasingly common, ground source heat local (CHP) biomass, while could come more decarbonised system. However, these improvements must set alongside many homes, demographic trends smaller households, holistic approach overall personal transport.
