Energy performance (Emilia Romagna system):

Architectural Shell + Systems

EPtot= 1,175 kWh/m3a(energy performance index)

1,17kWh/m3/anno




Energy saving:

EPtot= 1,175 kWh/m3a(energy performance index)




CO2 Emission:

Rispetto alle prestazioni limite minime che lo stesso fabbricato avrebbe dovuto rispettare secondo la normativa Regionale vigente, può essere calcolata la riduzione delle emissioni di anidride carbonica determinata dal raggiungimento della classe energetica ottenuta:




Zero emission:

La produzione di

energia elettrica annua

da conversione

fotovoltaica compensa

il consumo elettrico

annuo per

riscaldamento e per

illuminazione.

La scuola, dal punto di

vista energetico, può

essere definito un

intervento a impatto

e emissione zero.
