As an architect, a professor (ULB Brussels) and publisher, Sebastian Moreno-Vacca has successfully championed passivehouse building in his native Belgium. Today, passivehouse is the Brussels Region building code.

At the center of the Belgian Passive House movement is Architect Sebastian Moreno-Vacca of A2M who has spent years experimenting and building Passive House projects while offering technical support to the Belgian community by way of trainings, books, and magazines. He has also worked closely with government officials on public demonstrative projects and policies to promote Passive House including exemplary building programs, incentives, and technical feasibility studies for the European Union. Moreno-Vacca is now actively working on architecture projects and consulting on policy in NYC with his partner, Julie Torres Moskovitz of Fete Nature Architecture, architect of the first certified Passive House in NYC.
