34. 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:

35. 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.
