Mapping Residential Thermal Comfort Gap at Very High Resolution Spatial Scale: Implications for Energy Policy Design


The aim of the study is to determine heating and cooling energy needs and assess the energy gap on thermal comfort at households, both in heating and cooling seasons. The approach was applied throughout the 5 climatic zones of Portugal, ranging from the coldest, with more than 1800 heating degrees-day per year and a summer outside temperature between 20º and 22ºC and the warmest zone, with less than 1300 heating degrees-day/year and an outside summer temperature above 22ºC. All the 3092 civil parishes and approximately 3.8 million dwellings, occupied and of usual residence, were considered, while capturing specific details of construction, climate, average households areas for each region to support local dedicated energy policies and instruments.
