Air Barrier Case Studies
Marty Houston, AIA - Walsh Construction
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.

Passive Design: Using the building as the mechanical system
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.

2500 SW Moody
Sean Scott, AIA
CLSB is an acronym for the OSU OHSU Collaborative Life Sciences Building and Skourtes Tower project on the South Waterfront in Portland, just south of the I-5 bridge. Integrating several clients including OHSU, PSU, and others, this hyper-fast scheduled project with incredible complexities has demanded an evolution of the processes involved.
This enclosure case study tour is an opportunity to see the various phases of the different enclosure systems being installed. This is a follow up to the BEC CLSB Enclosure Case Study presentation on February 5th. Please bring your questions!
1. Access SW Moody via SW Naito Parkway on SW Harrison Street via street car via the SW River Parkway and Moody stop (and walk south bound on SW Moody about a quarter mile), or drive to the OHSU paid parking noted in orange on the map above.
2. Walk to the SW corner of the OHSU parking lot and go through the chain link gate 1 noted on the map above.
3. Upon walking through the 2nd gate, turn to your left and walk up the wood ramp and enter the door on your right and ask the receptionist to be directed to the collection point for the BEC tour.
Release forms will have to be filled out prior to the tour. You can download a form from the Tour Packet attachment and bring it with you to save time.
CLSB - Envelope Case Study
Sean K. Scott, AIA, SERA
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.

Building Envelope Commissioning
John Duncan, AIA, Morrison Hershfield
"Building Envelope Commissioning" will discuss the process of envelope commissioning and how the NIBS structure can be implemented. ASHRAE states, "The Commissioning Process is a quality-focused process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets defined objectives and criteria."
Drawing on project experience from across North America, the presentation will examine the need for commissioning the passive building envelope systems, the process, the challenges and the impact on energy performance.

Blast Resistant Design
Eve Hinman, Hinman Consulting Engineers
This course will focus on the concepts of blast resistant design as they relate to building envelope systems. The differences between ballistic, blast, and impact resistant designs will be discussed along with lessons learned from previous blast event. Opaque and transparent wall and roofing systems will be discussed within the context of blast resistance mitigation.
Eve Hinman pioneered the field of blast engineering. In 1983, she became one of the first structural engineers in the United States to take on this highly specialized design work, when the bombings of the U.S. embassy and Marine Barracks in Beirut brought to the attention of the Federal government the need for anti-terrorism solutions. Since then she has designed nuclear missile silos, NATO military facilities, industrial buildings subject to accidental explosions, and civilian buildings vulnerable to terrorist attack.
Eve received her doctorate in Engineering Mechanics, and her MS and BS in Civil Engineering from Columbia University (with structural emphasis). She is a registered Professional Engineer in California and New York.
Informed Decision-making: Integrated Facade Design and Analysis

Mark Perepelitza, AIA, LEED AP BD+C
Mark will present tools and resources for integrated facade design and analysis from the Building Technology Department at Lawrence Berkeley National Lab (LBNL). Their latest research includes testing and simulation of complex fenestration materials and assemblies. Tools from LBNL, including Window6 and COMFEN4, can provide valuable information to support intelligent decision-making in the design of integrated facades.
COMFEN supports the systematic evaluation of alternative fenestration systems for project-specific commercial building applications. It provides a simplified user interface that focuses attention on key variables in fenestration design. Under the hood is Energy Plus, a sophisticated analysis engine that dynamically simulates the effects of these key fenestration variables on energy consumption, peak energy demand, and thermal and visual comfort. The results from the Energy Plus simulations are presented in graphical and tabular format for comparative fenestration design cases to help users move toward optimal fenestration design choices. The presentation will include case studies which illustrate application of COMFEN to a number of recent projects.
Mark is the manager of SERA’s Sustainability Resources Group which provides sustainable design expertise, research and development, and sustainability consulting services to all of SERA’s project teams. Mark brings 20 years of experience in architecture, building performance research, and education. He has played a significant role in the creation of quality public buildings including university academic and laboratory buildings in Oregon, California, Colorado, Minnesota, and Ohio. Mark teaches university courses on building enclosure design and performance, and has presented at recent conferences on related topics. Mark’s study of high performance European façades included sessions in Seattle in 2010, and a symposium with leading practitioners and researchers from Europe and North America in San Francisco in 2010 in collaboration with LBNL, CBE, and the Pacific Energy Center.
Electronic Leak Detection for Building Envelopes
Aceh Community Room
Mercy Corps Building
45 SW Ankeny St
Portland, OR 97204
Tom Cooper, Progeo Monitoring
Electronic leak detection for roofs in almost any form, whether it is manually practiced or computer controlled, is based on the following principles:
1. High inherent electrical resistance of roofing membranes;
2. The ability of water to conduct and at the same time to act as a resistor to electrical current;
3. The ability of other materials to conduct and resist electric currents;
4. The ability of water vapor to distribute and concentrate in areas in the roofing envelope.
The first 3 combined elements can shape an electrical field which allows one to detect leakage in membranes and to determine the location of such leakage and the 4th principle allows systems to measure increase in overall moisture in a building envelope, indicating and roughly locating a leak. We are going to demonstrate how the 2 widely used manual methods of leak detection and how the automatic leak detection systems utilize the 4 principles. We will discuss automatic leak detection including detection of leakage at penetrations and edges of building envelopes, leak detection for multi-layered roofs utilizing more than one discreet membrane or an impermeable vapor barrier acting as one of the membranes, and how vapor tracking in a roofing envelope can help determine leakage.
