The current energy crisis requires us to re-evaluate our methods of energy usage. The UK government has committed to decarbonising all sectors of the UK economy to meet a net zero target by 2050. With approximately 24.8 million households in England and Wales (ONS, Housing, England and Wales: census 2021), it is important that residents understand how energy is utilised efficiently. Misunderstanding energy usage will negatively impact achieving the UK government’s 2050 net zero goal. Regarding domestic energy usage, identifying areas of consumer uncertainty and evaluating them through experimentation will educate the consumer, promoting clarity and understanding. This will assist towards achieving the UK net zero target, whilst encouraging sustainability through informed, efficient consumer energy usage. It was found that increasing space heating duration from 9 h/day using an SAP intermittent heating pattern to a constant 24 h/day heating pattern only increased space heating energy use by 31%. This behaviour is attributed to heating the thermal mass of elements during heating periods rather than more efficient heating system operation.
