AbstraktThe building envelope plays a key role in achieving building energy efficiency and indoor
comfort for the occupants. The most promising (and innovative) strategy for the building
envelope of tomorrow is based on a dynamic, active and integrated solution, able to optimize
the thermal performance, integrating active elements and systems, exploiting energy from
renewable source. Considerable efforts in research and development are necessary to achieve
a sustainable and effective building envelope with a dynamic behaviour. Within the field of
the light and transparent building envelope, a general trend in research can be drawn: along
with the innovation of the façade’s subsystems, researchers and producers are moving from
the double skin façade concept towards a more complex façade, where the functional
strategies are improved and the integration with active elements and the HVAC system is
deeper. The most relevant results of a decade-long research activity carried out at the TEBE
Research Group at Politecnico di Torino, on active and integrated building envelope, are here
presented. The analysis provides useful information about the contribution of each subsystem
(e.g. glazing, sun-shading devices, natural and mechanical ventilation...) to the achieved
energy efficiency and user thermal comfort. Furthermore, the paper also presents the concept
for an innovative façade module – which prototype is currently under construction –
conceived in the frame of a National Research Project. The ActResS module (Active,
Responsive and Solar module) is a dynamic building envelope element, capable of changing
its thermo-physical behaviour in order to maximize the energy efficiency and the
environmental comfort of buildings occupants.
