Integrated Facade Symposium

Integrating comfort and energy performance in elegant architectural solutions

Facade Symposium Banner

Innovative approaches to facade design are increasingly common in European buildings where air conditioning is used selectively. As we push for higher performance in sustainable buildings, there is much value to be gained by exchanging conceptual and technical knowledge between European and North American design professionals and researchers.

The PG&E Pacific Energy Center, Lawrence Berkeley National Lab (LBNL), and CBE organized a full-day symposium on April 21, 2010, to generate such a dialogue. These experts discussed case studies, performance, and research related to integrated facade design.

Design Practitioners from Northern Europe

Mikkel Kragh is an associate and facade engineer at the Arup office in Milan, Italy. He presented facade design with respect to energy, comfort, and structural performance. The projects presented, Plantation Place and Ropemaker Place, both in London, illustrate how architectural design concepts and various environmental factors can drive the detailing of the facade.

Facade Research Presentations

Stephen Selkowitz 

View presentation (18 MB PDF)
Stephen Selkowitz is head of the Building Technologies Department at Lawrence Berkeley National Laboratory (LBNL), where he provides management and technical oversight for five major R&D activities. He provided an overview of energy targets in the U.S. and strategies for achieving these targets in commercial buildings.

Eleanor Lee

Eleanor Lee, Principal Investigator at LBNLís Environmental Energy Technologies Division, discussed ongoing windows and daylighting research at LBNL, including the testing of new glazing products, and LBNLís testing and commissioning of the daylighting systems at the New York Times building.

Panel Presentations

The symposium included a panel session to encourage interaction between design professionals with considerable facade-related professional experience and our audience. Brief presentations by the panelists were followed by a discussion focusing on strategies for adopting advanced facade technologies within U.S. design practice.
Moderator: R.K. Stewart, Perkins+Will
