The impact of climate change uncertainties on the performance of energy efficiency measures applied to dwellings

Building simulations designed to investigate the potential impact of climate change uncertainties on the performance of insulation measures, applied retrospectively to an existing residential dwelling, suggest their effect could be considerable. Thermally, double glazing is the best option because although it is more sensitive than the others to climate change, it still delivers the highest savings in heating energy demand for the lowest induced cooling load. Loft insulation is the worst option in thermal terms.
