Lessons Learned from Three Multifamily Passive Buildings

Location: 

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

Presenters: 

Katrin Klingenberg

Description: 

The number of passive houses and buildings meeting the stringent PHIUS+2015 Passive Building Standards has increased exponentially over the past two years: first single family residential projects were built, then multifamily projects and now the trend is moving towards commercial structures. Many municipalities such as NYC have already incentives in place for residential passive buildings or are evaluating to implement incentives as a solution to meeting their climate action plans. This presentation takes a look at three completed case studies of low and midrise multifamily projects across the country that were constructed at 0-5% additional cost over an EnergyStar baseline. Successful construction techniques and lessons learned will be discussed.

Katrin Klingenberg is Co-Founder and Executive Director of the Passive House Institute US (PHIUS). In 2003, Ms. Klingenberg designed and completed the first home to meet passive house standards in the United States. She has designed and consulted on numerous successful passive house and building projects across North America’s varied climate zones since. In addition to her executive role at PHIUS she is the lead instructor for PHIUS Certified Passive House Consultant (CPHC®) training. In that role she directs curriculum development. She also directs the technical and research programs of PHIUS, and is a licensed architect in Germany. She frequently presents on the passive building topic nationally and internationally.

George Tsongas, Ph.D, PE

Description: 

Learn from engineer and building scientist, George Tsongas, who has studied, investigated and corrected numerous building problems relating to mold and IAQ, as he offers an overview of mold and moisture problems inside single and multifamily housing. George will help you understand what mold is, where and why it grows, the different types of mold, what are the true health impacts, litigation concerns, how to inspect for mold growth conditions, what are the best mold cleanup procedures, and what can be done practically and economically to remedy or prevent indoor mold and moisture problems. The pros and cons of moisture and mold control measures such as source control, ventilation, and dehumidification will be discussed. Specific approaches for improving bathroom and kitchen ventilation will be presented.

Dr. Tsongas is a consulting engineer and a Professor Emeritus of Mechanical Engineering at Portland State University in Oregon. He is a building scientist with specialization in moisture, mold and water intrusion problems in housing. He has directed a number of field studies of moisture and indoor air quality problems inside existing and new residences as well as investigations of ventilation and dehumidification moisture control strategies. He was invited to be one of five presenters for an ASHRAE- sponsored Satellite Broadcast/Webcast titled “Mold in our Building Environment.” Over 22,000 people from North and South America viewed the three hour satellite broadcast and webcast. He has inspected many thousands of dwelling units in seventeen states and Canada for moisture and mold problems over the last 35+ years.

Meeting Title: 

Transparent Systems - Detail Level Insight into High Performance Façades

Location: 

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

Presenters: 

Chris O'Hara, PE

Description: 

The session is a Case Study driven review of façade details for transparent systems. Where many education provide a review of the basic stock details the critical design issues often occur at the atypical conditions. The basic "rules of thumb" do not apply when the geometry or material choice require more from the design. This session will review the atypical conditions that do not occur in the idealized conditions. The course is crucial to those designing the enclosure of buildings that do not fit the mold of a common box. The case studies will include both transparent and opaque façade systems. Most importantly the discussion will include the junction of the transparent and opaque assemblies, where most facade failures occur. Important topics will include continuous insulation, mitigation of thermal bridges, condensation, waterproofing and structure.

Studio NYL, a Boulder, Colorado-based structural engineering and facade design firm known for its exemplary skills, has earned the trust and respect of architects around the world for delivering truly innovative design-led solutions that exceed the conventional.

Founded in 2004 by Chris O'Hara, PE and Julian Lineham, PE, Studio NYL's vision is rooted in the founders' belief that all architectural design can be elevated through the inventive use of structures that enhance rather than limit design. It is this passion for raising design standards through the "artful use of structure" on every project—whether humble or grandiose in scope—that drives their distinctively poetic approach.

Chris launched his career in New York City where he worked on many unique structural engineering projects as well as signature architectural buildings. From theatrical rigging and amusement park rides, to floating structures, huge facades and challenging structural glazing projects, Chris' training is rooted in one-of-a-kind initiatives like the Rose Center for Earth and Space, the Rolling Stones 'Bridges to Babylon Tour' and the Starlight Theatre.

Over the last few years, Studio NYL has grown rapidly from a firm focused primarily on smaller scale Front Range residential and institutional projects, to being known more broadly for its higher education, law enforcement, arts and other sector work throughout the Western Mountain Region. Today, in addition to its extensive portfolio of conventional building types of all sizes and complexity, Studio NYL is overseeing an expanding number of ground breaking global projects which allows the principals to explore new structural and architectural technologies, skin applications, environmental solutions and more. Chris and Julian also continue to seek out opportunities to reinvent existing traditional systems on landmark buildings around the world.

Achieving a High-Performance Air Barrier System

Location: 

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

Presenters: 

Todd Parrott

Description: 

Air Barriers are an extremely important component of a high-performance building enclosure system. For the most part, these systems are non-maintainable components and repairs can typically only be made with the removal of the exterior cladding system. To ensure a performing system, proper design, detailing and ultimately the proper installation of these systems is extremely important. You have one chance to get it right. Come learn about important design considerations, how to properly detail critical interfaces, key items to include in your specifications and the proper installation techniques, quality control and testing parameters for a variety of air barrier systems in use today.

Todd Parrott has been involved in the construction and building materials industry for more than 20 years. Mr. Parrott has been an architectural consultant and conducted years of education to the architectural community. He has spent the last two decades in the fenestration industry in roles such as window contracting owner, territory manager, architectural representative and sales in both the commercial and residential markets.
