#Workshop Objectives:

  • Bring to light the newest developments on sealing techniques, durability, test methods and analyses, challenges and solutions in high-rise buildings
  • Foster programs and networking activities regarding airtightness issues.

Major Topics:

  • How should airtightness be specified and controlled?
  • How does airtightness change with time, how can one assess and minimize this, and how does that affect the building’s overall performance over its lifetime?
  • What are the limits of today's solutions in high-rise buildings?


The workshop will include presentations from several countries on a variety of issues, approaches and solutions in their different contexts. Presentations will emphasize recent developments in test methods, building airtightness performance data, approaches to design, construction and commissioning that contribute to good airtightness performance, and the development of airtightness requirements in codes, standards and regulations. While much of the discussion will focus on commercial and other high-rise buildings, the workshop will also address residential buildings.

#Call for papers:

Interested parties are invited to submit an abstract by February 8, 2013 to Notification of abstract acceptance: February 15, 2013. Deadline for paper submission (optional): March 15, 2013. More information on and
