Energy Efficiency and Indoor Environment Quality

This Special Issue addresses a topic of great relevance. In developed countries there is a higher prevalence of people choosing to spend time indoors. Data show that the time a person spends at home ranges from 60% to 90% of the day and 30% of that time is spent sleeping though this varies depending on the individual. Taking into account these data indoor residential environments have a direct influence on human health. Furthermore in developing countries significant levels of indoor pollution make housing unsafe impacting the health of its inhabitants. Housing is therefore a key health factor for people all over the world: various parameters such as air quality ventilation hygrothermal comfort lighting physical environment and building efficiency can contribute to healthy architecture; poor application of these parameters can result in conditions that negatively impact health.
