brussels goes passive, what's in it for architecture

In this book, the Brussels-based university ULB, the Brussels Environment Agency, and the Passive House Platform have asked several experts (architects, engineers, contractors, sponsors, lawyers, )  including architectesassoc. to share insights on how and where practice MUST change, and how and why think-modes have been modified by the passive uprising. The debate is open, but hooting that 0,6 air-tightness will strangulate the real estate market is just as ridiculous as thinking that going passive is the only route to sustainable heaven. architectesassoc.  takes a clear stance:  C'est un discours peu relayé en Belgique vu le ramdam 2015, mais en tant qu'architectes cest bien de nos valeurs sociétales que nous devons débattre, et le passif c'est de la technique et la technique n'est PAS une valeur .
