energy and disproportionate cost of heating an inefficient building which in the housing sector may result in ‘Fuel Poverty’. In 2014, 11% of English households were defined as being in Fuel Poverty with around 1 in 5 people finding it difficult to afford the cost of heating their home. Living in a cold home can result in a series of avoidable health related problems, both physical and mental, and has been linked to increased cases of ‘Excess Winter Deaths’. A study of Wilmcote House by Southampton University had shown that many residents were under-heating their homes, well below WHO (World Health Organisation) recommendations, which exacerbated mould growth. This was largely due to the high degree of heat loss caused by the poor quality of the existing building and the expensive, inefficient heating system. Given the findings of this work and the ongoing deterioration of the block Portsmouth City Council (PCC) sought options to address these issues. | 09
