The Challenge of Understanding Non-Toxic Building Materials

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

James Connelly

Description: 

In the quest for durable, long lived building materials the construction industry has relied on products that are often toxic or harmful to the environment and the building occupants. This presentation discusses the Red List of toxic materials and what designers and specifiers can do to replace them. New trends in bio-based technologies will be discussed along with a challenge to the attendees to avoid such materials in their own practice.

James is a green building professional with a broad range of industry experience from design and construction to research and advocacy. He is a graduate from the University of Washington with degrees in Architecture and International Studies. Prior to joining the Institute, James worked on green building projects at the Seattle offices of MulvannyG2 and GGLO. After a trip to Hong Kong in 2008 he became fascinated with the incredible pace in scale of urban development in China and the potential for green building. James is fluent in Mandarin Chinese and recently completed a Fulbright Research fellowship in Beijing on green building evaluation systems in China. James is an avid writer and blogger, and and his research has been featured in news outlets such as China Dialogue and Engineering News Record. He currently manages the Declare, the Institute's building ingredients labeling program.

Punched Window Selection Criteria

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Sean K. Scott

Description: 

Most punched window selections are based on what the firm or team had on the last project, looks, and price. This course offers performance based selection criteria to add to the selection tools.

Sean is an Architect with Ankrom Moisan Architects that focusses on enclosures within his career. He is presently writing a book entitled "Enclosure Tools" that is created by the industry for the industry. His past speaking engagements have included AIA National, Living Future, and many local venues.

January 2014 Monthly Meeting

Time: 
Jan 7 2014 - 12:00pm - 1:15pm
Meeting Title: 

Air Barriers: A Panel Discussion

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Ken Roko

Ariel Levy

John O'Brien

Nathan Weibel

Description: 

Today’s design and construction environment is expanding at an increasing rate with product offerings and new technologies leading the push that result in more complicated buildings. The selection and installation of air barrier systems is no stranger to this phenomenon. The technology of sheet applied and fluid applied air barrier systems have progressed at a rapid pace over the last 20 years with so many different product offerings, chemical compositions and installation methods that the choices can seem daunting.

This presentation will involve a panel discussion with members of the panel representing the manufacturing, installation and specification sides of the process. The discussion intends to speak to current state of air barrier technology, the challenges of each type, what’s important from the manufacturing side, design side and applicator side, and what we see for the future. The panel will consist of Ariel Levy of RDH Building Sciences, Nathan Weibel of Henry Company, and John O’Brien of Western Partitions.

December 2013 Monthly Meeting

Time: 
Dec 3 2013 - 12:00pm - 1:30pm
Meeting Title: 

Open Joint Rainscreen Assemblies Design Considerations and Case Studies

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Claude Louvouezo, AIA

Mark Rose

Description: 

Recent years have seen an increased trend towards rainscreen cladding system. These systems typically consist of an exterior cladding, a drainage cavity and a back-up weather resistive barrier. Traditionally in rainscreen cladding designs, the joints in the exterior cladding are sealed to minimize the potential for water intrusion into the drainage cavity with the exceptions of weeps and pressure equalization vents which are generally sheltered from water ingress.

In the open joint rainscreen systems, the joints between the cladding elements are intentionally left open.

This presentation will discuss the implications of open joints for the performance of rainscreen systems. Various approaches to the design of open joint raDeinscreen cladding systems will be reviewed. Two construction case studies demonstrating successful and unsuccessful implementation of the open joint rainscreen concept in the field will be presented.

Claude works as a Building Envelope Specialist in the Building and Facilities Division of Morrison Hershfield in Portland. He completed post-graduate architectural studies focusing on building technology. He developed an expertise in the design, detailing and construction oversight of building envelope assemblies and has been involved with all aspects of building envelope services.

Mark Rose is Technical Lead for Building and Facilities Division of Morrison Hershfield in Portland. He is a building technologist specialized in building envelope assessment, design, rehabilitation and field review. Before coming to MH, Mark was employed as a contractor and oversaw the rehabilitation of a variety of distressed buildings resulting from water intrusion issues. He also has expertise on the investigation, assessment and conservation of historical buildings.

November 2013 Monthly Meeting

Time:

Meeting Title: 

Cross Laminated Timber - The Wood Story

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Ethan Martin, PE

Description: 

Beginning with an overview of sustainably managed forests, life cycle analysis, and the carbon cycle of wood, this presentation introduces the current thinking on architectural and structural use of Cross Laminated Timber in buildings with a focus on high rise projects. Included will be a short history of CLT which began in Europe and a discussion of building enclosure strategies.

Ethan Martin, PE is Senior Technical Director, Pacific Northwest US for WoodWorks. He is based out of Seattle, WA. Ethan received a B.S. in Civil and Environmental Engineering from Cornell University. As the previous owner of a structural engineering firm in Asheville, NC, Ethan has worked on projects that range from small renovations and additions to a 470,000 square-foot, $125 million central school for the Cherokee Nation.

In his role with WoodWorks Ethan serves as a wood products industry spokesperson and educator dedicated to growing the knowledge and use of structural wood products in non-residential construction through a variety of forums and seminars reaching over 1,000 design professionals annually. He currently serves on both the Midrise Construction and Schools initiative WoodWorks teams, and his primary role as Senior Technical Director, directly consulting with design professionals to educate and successfully implement wood into their designs.

October 2013 Monthly Meeting

Time: 
Oct 1 2013 - 12:00pm - 1:30pm
Meeting Title: 

Sealant Adhesion and Compatibility Study

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Sharon Libby, Walsh Construction

Description: 

This presentation will explain how this sealant adhesion and compatibility study was conceived and executed and will also provide conclusions about the observed reactions between many different substrates and sealants. This study was executed to determine the varying levels of adhesion between commonly specified sealants and substrates (including weather resistive barriers, self adhered membranes, liquid applied membranes and cladding components including brick, fiber cement cladding and various window materials. Similarly, observed compatibility issues will be discussed and the cause of the incompatibility explained in order to better inform designers about posssible adverse reactions between materials.

Sharon Libby is a Quality Assurance Manager with Walsh Construction. Sharon has a Bachelor of Architecture degree from the University of Oregon and worked in architecture for about 8 years before making the switch to construction with Walsh’s Quality department. There she is involved with several projects providing reviews and field research during pre-construction and active construction phase. Concerns raised in the field are a great motivator for Sharon to research and solve problems. The sealant study Sharon conducted is a great example of that process.
