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.

March 2013 Monthly Meeting

Time: 
Mar 5 2013 - 12:00pm - 1:30pm
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.

Blast Resistant Design

Location: 

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

Presenters: 
Description: 

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.

October 2012 Monthly Meeting

Time: 
Oct 2 2012 - 12:00pm - 1:30pm
Meeting Title: 

Informed Decision-making: Integrated Facade Design and Analysis

Location: 

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

Presenters: 

Mark Perepelitza, AIA, LEED AP BD+C

Description: 

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. http://windows.lbl.gov/software/comfen/comfen.html

September 2012 Monthly Meeting

Time: 
Sep 4 2012 - 12:00pm - 1:30pm
Meeting Title: 

Electronic Leak Detection for Building Envelopes

Location: 

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

Presenters: 

Tom Cooper, Progeo Monitoring

Description: 

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.

Thomas Cooper is the Executive Vice President of Progeo Monitoring of North America. He is responsible for business development, AIA Continued learning programs, and corporate client services.
