3.1 Energy and Environmental Analysis of The Retrofit
Actions: Benefits and Drawbacks
Energy and environmental analysis was carried out by means of suitable and
meaningful indicators, which were assessed and presented at the level of mid-point
indicators according to the data format of the environmental product declaration
(EPD) scheme and recommended by ISO 14040 (EPD
2008
; UNI EN ISO 14040
2006
). Therefore, the following indicators were taken into account:
In particular, the requested information concerned the following categories:
• Gross energy requirement (GER).
• Global warming potential (GWP).
• Ozone depletion potential (ODP).
• Acidification potential (AP).
