Climate change phenomena such as global warming and urban heat island effects cause serious problems for the development of building technology.

Few studies focus on commercial low-rise buildings which are often characterized by low-cost constructions materials and weak energy performances.

The European Union (EU) aims to a 20% reduction of the Europe's annual primary energy consumption by 2020. Furthermore, EU commits to reduce GHG emissions to 80-95% below 1990 levels by 2050.

From 2006 till 2012, the 2005 energy performance (EP) regulation (RT 2005) did not entail any obligation to justify the envelope airtightness level.

The principle of roofs cooling through the water vapour adsorption-desorption cycle in porous materials is presented.

The materials that are used in outdoor spaces are of prime importance as they modulate the air temperature of the lowest layers of the urban canopy layer, they are central to the energy balance of

The Proceedings of the 34th AIVC Conference " Energy conservation technologies for mitigation and adaptation in the built environment: the role of ventilation strategies and smart materials",

Ventilation’s historical goal has been to assure sufficient air change rates in buildings from a hygienic point of view.
