Abstract/Resumo
Climate change and future weather conditions are likely to challenge the way
buildings are designed because there will be an increase in extreme climatic conditions. What
should architects change in their design process to produce human habitats able to withstand
those extreme conditions to ensure adequate comfort conditions? This paper presents preliminary
results within the scope of an on-going research that addresses one single key issue: what
materials will be most suitable in extreme temperature conditions. A set of 52 materials is
analysed through a multi-criteria decision process that includes thermal conductivity, thermal
diffusivity, thermal effusivity, linear thermal expansion, service temperature, fracture toughness,
recycle potential and embodied carbon as criteria. The goals are to find the best-fit materials for
each climate scenario within the scope of contradictory objectives and to develop a methodology
for the selection of construction materials for buildings in challenging environments. Results
show that the best possible material for extreme temperatures, whether it would be a very cold
or a very hot environment, is one that could combine the properties of polymers with a very low
environmental impact (at the level of the impact from materials such as natural fibres, wood or
wood derivatives). The results thus suggest that further research may be directed at biomaterials
development.
