In order to study the natural light, it was used the Velux software called “Daylight Visualizer”. Thanks to that, it was possible to calculate the daylight factor in each room and verify the respect of minimum values according to British Standard BS 8206-2:2008 “Lighting for Buildings”.
About the air quality, a mechanical ventilation system was designed to guarantee the comfort conditions, expecially in summer and winter, when the benefits of midseasons ventilation cannot be exploited.
A highly performing envelope wad obtained by using envelope strategies, such as ventilated façades and green roofs.
Windows and solar shieldings have been designed considering the orientation of the buildings, to exploit solar gains, expecially in winter, and to block high summer solar contributions.
Windows were placed on the roof to allow more natural light to enter in a diffused way. Moreover, the chimney effect was used to allow the stale air to come out naturally, without the mechanical ventilation.
On the southern façade, a fixed shielding system in horizontal direction, was installed to screen the large windows.
On the west front, a micro-perforated metal shelter was installed to protect the
study rooms from the afternoon solar radiation.
The positive impact on the environment was obtained by using sustainable materials and renewable sources. For example, a thermal-acoustic polyester insulation composed by recycled PET fibers was used for the insulation in the interspaces. For the horizontal partitions, it was used an acoustic insulation composed of textile scraps.
In order to make more free energy available, photovoltaic, solar and geothermal systems and a 2500 liter rainwater storage tank were placed in the underground area.
