Windows Workshop

Thursday, 27 April 2017, 2:30pm - 6:30pm

Messe Wien Congress Center, Messeplatz 1, 1021 Vienna, Room: Business Suite 2, Level 1

The global demand for highly efficient and cost-effective windows exceeds the present production expertise and leads to market gaps. This seminar is aimed at manufacturers, developers and other interested parties and contributes to the exchange of expertise on high-performance windows to address this issue.

The purpose of this workshop is to encourage window manufacturers worldwide to design, certify and produce Passive House Windows on local scales. This, in turn, will facilitate the specification and ordering of Passive House compliant windows and doors for the Passive House communities around the world.
