Motivated by the need to strengthen its structure for seismic reasons and to reduce its energy consumption, this school in the Lombardy Region of Italy – Bergamo Province – has achieved an 80% reduction in energy use whilst paying special attention to the thermal, visual, indoor-air and acoustic comfort of its users.

Following its closure in 2014 over concerns about seismic safety, this school has been transformed in all of its physical aspects to achieve an exceptional level of energy performance.  The climate zone in which it is situated is humid continental, meaning high precipitation and large swings in air temperature throughout the year.  Taking a holistic approach, where the comfort of the pupils was uppermost, has produced an exceptional result.

As the school is located near a high-speed rail line and a busy motorway, great attention has been paid in choosing products with a multiple comfort approach to improve envelope heat loss and acoustic performance simultaneously, while maintaining high transparency and brightness with correct diffusion of natural light.  To significantly improve indoor air quality, purifying products were installed together with an ionisation unit in the ventilation system.

The energy renovated building has been welcomed very enthusiastically by the local community and, even two years after completion, the enthusiasm has not gone away.


Principal Characteristics of the Renovation Works:

Ownership type: Public
Year of construction: Circa 1950
