Understanding how sustainability (or: green building) rating systems function is not always an easy task. Grasping the subtle differences between the various international systems such as LEED, BREEAM, and DGNB can be an even harder challenge. WSGT’s sustainability expert Giulia Peretti has now published (along with her sister Clara Peretti) two Italian-language articles that help users getting a better overview. The two articles are titled “Protocolli di sostenibilità italiani e internazionali a confronto” and “DGNB: come funzione il protocollo di sostenibilità tedesco” respectively. They can be found on the website www.ingegneri.info.it and were published on 25 and 26 May 2017, respectively.
