Mitigating the risk of overheating and associated thermal discomfort inside school classrooms is a global concern due to its significant impacts on students’ academic performance, health and wellbeing. Thus, rising ambient temperatures resulting from climate change can be challenging, especially in low energy schools designed to optimise their heating season performance. According to recent studies, many low energy school buildings fail to meet comfort standards and experience overheating, resulting in low student productivity and the need for using air conditioning systems.

Building designs to be in line with energy efficient and carbon reduction goals, often focus on energy efficient techniques like high insulation, airtightness. However, these buildings are often subjected to overheating risks due to unforeseeable events like frequent heatwaves and power outages even in moderate climate zones like Belgium. Overheating risks in residential buildings have negative impact on the health of the building occupants (especially on the vulnerable occupants like elderly, infants and sick persons), causing sleep deprivation, heat stress and even mortality.

In future years the frequency, duration and magnitude of extreme heat events, such as heat waves, is expected to increase due to climate change. The population is exposed to higher thermal discomfort and risk at home and, at the same time, high external temperatures make it more difficult to cool their household through natural ventilation.
In order to propose adaptive measures, research should first assess the thermal resilience of the existing residential buildings when exposed to prolonged heat stress. Poorly insulated and non-equipped buildings typical of Southern

By 2050, the entire built environment must be climate neutral. Before that final date, we have to find an alternative to the use of fossil energy in the built environment. The switch to a climate neutral built environment requires an integrated approach, focusing on switching to alternative, non-fossil fuels and on reducing the energy demand by taking energy efficiency measures.
In the framework of The Trento EEMI Bauhaus Week, the European Mortgage Federation - European Covered Bond Council (EMF-ECBC) released a video-”call to action” (for distribution to 2000 banks and 5000 major companies) about the decarbonisation of buildings and the heat mitigation in cities.

Overheating in buildings is expected to increase as global warming continues. This could lead to heatrelated problems ranging from thermal-discomfort and productivity-reduction to illness as well as death. From the indoor-overheating point of view, the sensitivity of 9,216 Dutch dwelling-case to the climate change is quantified and ranked using detailed simulation and post-processing calculations. The results show that the sensitivity depends significantly on the dwelling’s design/operation characteristics. Minimally-ventilated dwellings are the most sensitive ones.

Overheating in buildings has been identified as an essential cause of several problems ranging from thermal discomfort and productivity reduction to illness and death. Overheating in buildings is expected to increase as global warming continues. The risk of overheating in existing and new buildings can be reduced if policy makers take decisions about adaptation interventions quickly. This paper introduces a methodology for supporting such decisions on a national level.

Heatwaves are often responsible for many deaths due to high temperature indoors. Energy savings is a key element in building design and refurbishment works to reduce the impact of climate change. Natural ventilation is often promoted as an indoor space cooling solution thanks to its energy saving potential.
The paper deals with prediction of heat-related health risks situations in naturally ventilated dwellings.

According to researchers, climate change is inevitable in the 21st century. As far as Greece is concerned, this climate change will be related to an increase in ambient surface temperature and to a decrease in annual precipitation. On the other hand wind patterns will not change significantly. Also, no significant changes are expected for global solar radiation. Regional climate models related to Greece show low uncertainties. The climate of Greece is typical Mediterranean with wet, cool winters and hot, dry summers.

The Low Income Group (L.I.G) in Lagos, Nigeria represents about 70% of the 18million population of the state. They are an important part of the economic activities in the state, with the bulk of public transportation and informal trading being undertaken by these groups. Housing, as the second most important human need after food has a profound influence on the health, efficiency, social behaviour, satisfaction and general welfare of the community.
