Modulation performances in the building envelope: strategy and project

This paper focuses on the analysis of a strategy aimed at improving the thermal performance of buildings thanks to the design of building envelope that could determine their natural thermal behavior, instead of fostering an excessive use of air conditioning systems. The true design innovation has the goal of conceiving envelope solutions capable of modulating the signals coming from the outside, so that the various structural elements that delimit the interior space could be able to re-emit them, strengthening or reducing them according to performance targets. In the design phase the site analysis is fundamental: it has to include both environmental and climate factors in order to check the critical issues and those potentialities offered by the site that could be useful to control the indoor environmental conditions. A methodological approach also requires the measurement of the performance to improve it, thanks to the use of iterative measurements and numerical models.
