An increasing number of companies places ecology, energy saving and respect for the environment at the centre of their lifestyle.
Sustainable development projects prefer materials which use up less grey energy, which is the energy spent in the extraction of the raw materials, in their transport, packaging, storage, disposal and recycling.
The construction industry has profound effects on the environment. So, as far as it is possibile, the negative effects linked to the production of materials, the construction of buildings and their demolition, the recycing of materials and the construction site waste disposal must be kept to a minimum.
Photovoltaic materials used as building material have a short pay-back time (time needed to produce energy destined to compensate that is spent in its production) and are recyclable.
