Meeting Title: 

NFPA 285 - Assembly Test of Exterior Walls with Combustible Components

Location: 

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

Presenters: 

Maria Spinu, PhD

Description: 

NFPA 285 is the Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components. NFPA 285 assembly tests are required by the International Building Code (IBC) when exterior non-combustible walls contain combustible components. The scope of materials classified by the IBC requiring NFPA 285 testing is increasing. Combined with more stringent energy code requirements, the use of combustible materials is also growing in exterior walls. This seminar will discuss the impact of the NFPA 285 Test on buildings using IBC and ASHRAE 90.1 energy code requirements, the parameters and history of NFPA 285, and the definition of what building envelope components are combustible and require NFPA 285 testing by IBC. All of these elements combine to integrate NFPA 285 compliant assemblies into building envelope systems.

Maria received a Master’s Degree in Chemical Engineering and Ph.D. in Polymer Science and Engineering from Virginia Tech. She joined DuPont Central Research & Development in Wilmington, Delaware in 1990 as a Research Chemist and in 1995 she was promoted to Research Manager. In 2000 she joined DuPont Building Innovations as New Business Development Manager.

She currently leads Building Science and Sustainability initiatives for the commercial market. Her background in engineering, materials science, and building science provides an insightful understanding of current challenges in achieving sustainable building enclosures. Maria advises building professionals on the best alternatives for achieving energy efficiency without compromising durability of the building enclosure.

Meeting Title: 

Water Testing Using PPV Fans to Simulate Wind-Driven Rain

Location: 

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

Presenters: 

Jasha Kistler

Mike Williams

Description: 

We believe this testing methodology is an innovative new approach of simulating the effect of wind-driven rain on the building enclosure to investigate water intrusion. The method builds on existing standards and utilizes readily available equipment to provide a cost effective, versatile, time-saving, and realistic means of replicating weather events to recreate leaks. In conducting hundreds of leak investigation tests, this technique has proven to recreate leaks quickly and without overloading the building’s water management systems. It is our belief that this method expands the knowledge of testing industry in providing a procedure that is a valuable tool for the forensic leak investigator.

Air Barrier Case Studies

Location: 

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

Presenters: 

Marty Houston, AIA - Walsh Construction

Description: 

Different approaches to constructing air barriers have varying implications for cost, constructability, complexity, and effectiveness. This presentation will describe the air barrier approach on three different projects, evaluating the impact on the cost and constructability of each approach as well as a description of the testing methods and resulting measurement of the air tightness of the buildings involved. Additional discussion regarding the areas of air leakage and lessons learned when employing various different approaches will inform the effectiveness of each approach.

With a B.Arch from the University of Cincinnati, Martin Houston is an architect licensed in the State of California. Mr. Houston practiced for 16 years before joining Walsh Construction's QA/QC program in 2006 and is currently the Quality Director for Walsh. He is a LEED AP, a Certified Building Science Thermographer and is a Certified Document Technologist through the Construction Specifications Institute

March 2013 Monthly Meeting

Meeting Title: 

Passive Design: Using the building as the mechanical system

Location: 

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

Presenters: 

Susan Hayes

Description: 

A “passive” approach to building design uses architectural and building enclosure elements aligned with local, micro-climate considerations to meet thermal comfort requirements. This can significantly reduce the need for “active” mechanical and electrical equipment that would typically provide heating, cooling, ventilation and lighting. Ideally, a truly passive building would eliminate the need for active equipment all together. This presentation will discuss common passive design features and their potential for reducing annual energy consumption, including case studies from building projects where passive strategies have been employed.

Susan Hayes, P.Eng. is a mechanical engineer with a focus on sustainability and energy efficiency. She is experienced in the design of low-energy mechanical systems and energy modeling in a variety of software tools. Susan’s project accomplishments include: leader of the LEED energy modeling team for the Vancouver 2010 Olympic Athlete’s Village; mechanical consultant for Vancouver’s first LEED Gold office building and presenter at a number of seminars and events. Prior to joining RDH in early 2012, Susan worked as a designer for a mechanical engineering firm and as sustainability project manager at an integrated design firm.

CLSB - Envelope Case Study

Location: 

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

Presenters: 

Sean K. Scott, AIA, SERA

Description: 

CLSB - Collaborative Life Science Building is an extremely complicated, hyper-fast construction schedule project with several large clients and an amazing set of functions housed within the building. The building enclosure was developed with key lessons that will apply to most other building types. The complexity of the schedule, team, functions, and enclosure performance program all combined to make an interesting project. This course is intended to share the lessons that have been learned and are continuing to evolve through construction.
