Energy Consumption and Rebound Effects

摘要

When comparing calculated energy consumption for heating,assuming standard usage,with measured data in residential buildings,then the two typically does not fit.In fact,measured consumption may be a fraction only of what was calculated.The main reason for that is rebound behavior.The paper shows its importance through exemplary cases,starting with the temperatures,measured in daytime and night-time rooms in a sample of dwellings.Then follow two small scale analyses of energy data gained in low-income homes.Next test results on rebound in two dwellings,one non-insulated,the other well insulated,are given,which prove that the benefits are much larger in non-insulated than in well insulated houses.That fact is used to interpret consumption data gained in 964 homes.The paper ends with data showing the effect of energy price on rebound,proving this clearly is an element impacting direct rebound.
