Home Insulation Makes Little Difference To Energy Consumption–New Study

An unusually frank piece from the Guardian!!
Conservatories and house extensions could be helping to wipe out the reductions in gas use secured by insulating homes, according to a study that found insulation only provides a short-term fall in energy consumption.
In a surprise finding, the study into the long-term effect of loft and cavity wall insulation in England and Wales showed that the fall in gas consumption for each household was small, with all energy savings disappearing by the fourth year after it had been fitted.
Policy experts at the University of Cambridge said the findings suggested a “rebound effect” in energy use, where changing behaviour cancelled out the reductions in gas use. They also suggested that fitting insulation often happened alongside the building of house extensions, which use extra energy. For households with conservatories, any gains in energy efficiency disappeared after the first year.
