Building Enclosure Fundamentals from the Perspective of a New York Architect

Location: 

University of Oregon-Portland
White Stag Building
70 NW Couch, Room 142/144

Presenters: 

Chris Benedict

Description: 

Chris Benedict, using examples of her own work, will talk about the evolution of the system approach to building design and the profound position that the building enclosure holds as a part of that system. She will lay out her perspective on building enclosure fundamentals, including the management of air, water, vapor, light and heat and discuss how mechanical systems and materials can be refined, reduced or eliminated, while building performance is enhanced, when the relationships within the system are clearly understood. Most of her discussion will be about innovations in the many apartment buildings she has designed and seen through construction, both retrofits and new construction. Some unusual aspects of her practice include: Inventing new construction techniques and building systems Changing code Stepping out of the traditional role of “Architect” and into Engineering and “means and methods” She will talk about the importance of thorough construction documents, active construction monitoring and crunching energy bills. Chris will end her talk with a presentation of her newest building, a 24 unit apartment building about to start construction that is planned to meet the strict German Passive House Standard.

Chris Benedict is an Architect, a Graduate of Cooper Union for the Advancement of Science and Art, and a professor of Architecture at Pratt Institute.

Keeping up with Glass Technology

Location: 

University of Oregon-Portland
White Stag Building
70 NW Couch, Room 142/144

Presenters: 

Stanley Yee

Description: 

The use of glass and fenestration as part of the building enclosure material/system has become a significant consideration and component in today’s building design. Glass in a building enclosure is used as the medium that breaks down the visual/psychological barrier between the interior and exterior of a building. Glass introduces natural daylight into a space and provides views of the outside while it simultaneously keeps the forces of nature to the exterior.

However, glass and fenestration technology has also rapidly evolved in recent years - predominantly to address energy conservation concerns. These advancements and product offerings range in aesthetics, performance and application. This meeting will explore and discuss current glass and glazing system technology and how the wide range of product availability can be more optimally incorporated into our projects with desired aesthetic and performance results.

Stanley Yee is a partner and building enclosure consultant for The Facade Group, a building enclosure consultancy based in Portland, OR. The Facade Group provides building enclosure design/construction expertise and support to building owners/developers and the architectural/engineering/contracting community.

Presenters: 

John Breshears

Description: 

The University of California San Diego is has commissioned the design of a new 177,000 square foot Health Science Research Laboratory on its main campus in La Jolla, CA. Based the on the experience and the mission of the institution, one initial goal for the project was to create as nearly as possible a daylight-autonomous laboratory building. The goal was subsequently refined to include the design and optimization of a façade system that yielded the maximum daylight benefit with minimal cooling penalty. John Breshears will present the design, simulation, and analysis findings relative to building envelope as well as a site-specific dynamic solar shading and glare control system. John will also give a brief description of the concept for an enthalpy recovery ventilated façade system. This project was recently awarded a research grant under the Department of Energy’s ARPA-E program for development by a team including Architectural Applications LLC, Membrane Technology Research Inc., and Lawrence Berkeley National Laboratory.

Lew Harriman

Description: 

Practical Tips & Traps for Better Building Enclosures Presented by Lew Harriman Thursday October 28, 2010 12-1PM PST A joint effort of the American Institute of Architects and the Building Enclosure Council

In the past, the building enclosure has often been where architecture meets engineering and construction in a family feud of confusion over responsibilities, sometimes resulting in water leakage, energy waste and construction defect litigation. Past practices are not going to work in the future. Feuds are too expensive and they rot the souls of dedicated designers and builders. This webinar will focus on a few practical tips, as well as a discussion on traps to avoid which help the building use less energy and last a long time, while providing the comfort that the public deserves. The ultimate key to successful thermal performance of building enclosures may be in a practical tip that comes from both President Ronald Reagan and Felix Edmundovich Dzerzhinsky, the founding Director of the Soviet KGB.

In 2006, Lew was the Chief Thermographer and lead author for the General Service Administration's Protocol for the Exterior Inspection of Building Enclosures Using Thermal Cameras. He also serves as a National Peer in GSA's Design and Engineering Excellence program. In 2009, Lew was the lead author and project manager for the ASHRAE Guide for Buildings in Hot & Humid Climates, a book which summarizes the experiences of building professionals in hot and humid climates around the world, and also summarizes ASHRAE guidance on ventilation, energy efficiency, thermal comfort and mold risk reduction with respect to hot and humid climates. In addition to his research and consulting, Lew is a teacher. He has developed instructional curricula and taught courses in humidity control and moisture management in the US, Canada, Latin America, Europe and the Pacific. He is also Vice Chair of ASHRAE Technical Committee 1.12 - Moisture Management in Buildings, and Chair of the ASHRAE Position Document Committee on Indoor Mold.

Presenters: 

Graig Spolek

Description: 

This Month’s Meeting: “Measurement of Green Roof Performance”

Green roofs are basically low maintenance gardens grown on the flat roofs of commercial and institutional buildings, whereby the building’s conventional roof is covered with a waterproof layer, a drainage layer, soil and plantings of grasses, shrubs or flowers. Many advantages are offered by eco-roofs, including storm water control and reduction of roof top heat flux. Field monitoring studies on three green roofs located in Portland, OR have shown savings in both areas. To better identify ways to optimize green roof design, laboratory tests have been preformed. Lab results show that plants using more water in summer can reduce building energy requirements.
