SUSTAINABILITY REPORT 2016
Indoor Air and Energy Certification
The construction of new buildings with drive was performed according to
the electrical certification requirements, and complying with the laws cur-
rently in force and through the management and monitoring of ADENE and
of the General Office of Energy and Geology. The buildings were awarded
with the energy classification of A, which is calculated taking into consi-
deration the following criteria: analysis of the building elements like walls,
windows, roof, floor, among other factors; analysis of the efficiency of the
equipments used for air conditioning and water heating, and analysis of
the use of renewable energies.
When checking the performance indicators, it is possible to say that the
buildings have become:
• 66% more efficient than the reference, in cooling of ambient temperature;
• 36% more efficient than the reference regarding the installed lighting
(LED technology);
• 47% more efficient than the reference regarding sanitary hot water, due
to the use of solar heat collectors to heat the water.
In order to achieve a good thermal coefficient, the walls are built, from
the inside to the outside, with double plaster board, air gap, stone wool,
sandwich panel and metal plate. Roofing is composed of, from bottom to
top, plasterboard, air gap, metal plate, stone wool and waterproofing. The
window openings use a 4 mm colourless glass, a 22mm air gap and have
a solar coefficient of 0.5.
