This two-day symposium will explore the state of the art of building science and the sustainability of current materials and enclosure designs.

This will be a follow up meeting to the first Eco-Roof meeting. This program will be a panel of suppliers and subcontractors discussing Green/Eco Roofs. Each panel member will discuss where we are today, the learning curve we have gone through and the direction we are heading. The panel will field questions from the audience and consists of four members.

This will be the final meeting of the series on Eco-Roofs. This program will be a panel of specialists discussing design considerations of Green/Eco Roofs. The panel will field questions from the audience and consists of three members.

This month's meeting will focus on using and deploying data loggers to monitor the performance of building enclosure assemblies. A brief overview of the generally available technology will be provided and the presenters will describe several projects where data logging is being used to address questions regarding building performance. As important as knowing that you can gather the data is understanding why you might want to and what you can do with the data once you have it. Three presenters will speak about data logging in reference to different areas.

The April meeting will explore two different methods for safeguarding your building against water intrusion problems.  These solutions are integrated into the design of the building.  The two technologies work differently but serve similar purposes.  Electronic Field Vector Mapping can be used to confirm and then locate breaches in waterproofing membranes.  The technology enables a quick and focused resolution to a problem.

This presentation is an interactive discussion of glazing systems ranging from a punched window to monumental tension glass walls. The conversation will weave through storefront systems incorporating common stick built curtain wall and custom designed unitized walls. We will cover water management concepts, anchorage methods and how these systems accommodate the critical building movements. Bring your questions and stories for an informative and useful discussion.

Building acoustics is an area we hear about more and more frequently and often with respect to litigation. Tobin Cooley of Listen Acoustics will be presenting some of his knowledge on building acoustics. Tobin will discuss what is considered to be normal levels of noise in multi-family occupancies and discuss some of the issues to be concerned with in designing multi-family residential occupancies as well as various types of testing that can be done. He will also perform a listening example of the difference between various window types in reducing train or freeway noise.

This Month's Meeting: Sealant Adhesion and Compatibility with Self-Adhered Membranes. The September 13, 2007 BEC meeting will be a follow up of the presentation given last June which focused on sealant adhesion and compatibility with self adhered membranes. Ken Roko and Dave Young will discuss some additional results, their findings and the outlook for the interface of these materials.

Dave Young of RDH Building Sciences, Inc. will discuss requirements of the 2007 Oregon Structural Specialty Code pertaining to the need for air barriers. Various different methods of achieving airtightness will be explored along with commonly used air barrier materials. The presentation will also look at problems and failures with various air barrier conditions and lack of airtightness in buildings.
