White Stag Building
70 NW Couch, Room 142/144

Presenters
Ariel Levy
Description

For the opening presentation of the 2010-2011 Portland BEC season, we thought it appropriate to begin with some building science basics. Mr. Ariel Levy, P.E., of RDH Building Sciences, Inc., will take a somewhat off-directional and (possibly) entertaining twist to this topic. He will present some different perspectives on the classical heat, air, and moisture control functions, including some side commentary on current building code and general industry practice that may not be all that consistent with general building science principles.

Meeting Title
Skins: The Importance of the Thermal Envelope
Location

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

Presenters
Ruwan Jayaweera
Registration

In the U.S., buildings account for roughly 40 percent of all annual energy consumed and 40 percent of all carbon dioxide emissions. So as members of the building design industry, we have a responsibility to design as efficient a building as possible. In the Northwest climate, the building envelope plays a major role in determining the amount of energy the building uses. This seminar will discuss how the envelope factors in to the building’s energy use.

Meeting Title
Measurement of Green Roof Performance
Location

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

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.

Graig Spolek is a Professor of the Mechanical and Materials Engineering Department at Portland State University. His educational background includes BS and MS degrees from the University of Washington and a PhD from Washington State University, all in mechanical engineering. At PSU, Spolek teaches courses in thermodynamics, heat transfer, instrumentation, thermal systems design and design of experiments. His research areas include fundamental heat and mass transfer, industrial energy utilization and measurement green roof performance.

Alan Seymour
Description

The call for higher energy performance buildings is being heard loud and clear. A new state wide code is being released this summer with changes that affect envelope construction and design by changing critical energy performance criteria. In preparation for the July 1 adoption of the 2010 Oregon Energy Efficiency Specialty Code (OEESC), based on the IECC, Portland BEC will host a presentation that highlights what changes have and haven’t taken place in this code cycle. Alan Seymour from the Oregon Department of Energy will present the new energy code requirements as they apply to the building envelope.

Meeting Title
Envelope Opportunities with the Living Building Challenge
Location

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

Presenters
Sean Scott
Description

This presentation has been requested and scheduled for the AIA National Convention June 11, 2010. As an early viewing of the same presentation, we will briefly review the latest version of The Living Building Challenge 2.0, while discussing envelope opportunities within this progressive framework. The Living Building Challenge is a measure of sustainability far more progressive than LEED Platinum or Triple Net Zero alone. This system does not contain points, rather 20 simple but profound imperatives that is performance based, not prescriptive.

The presentation focuses on a half dozen imperatives, showing what the envelope opportunities are and how they have been implemented on several projects. Those wanting to learn more about skin sustainability and the Living Building Challenge should attend this presentation. Since creating a more sustainable skin design is an imperative charge for the new decade, it is relevant and imperative to discuss this topic.

Sean Scott is a licensed architect with 2 professional architecture degrees currently working at SERA Architects in Portland, Oregon. Sean has 15 years of experience, 11 years of which working on LEED buildings and 2 years working and researching with The Living Building Challenge. Sean is actively involved with 5 committees within the BEC and COTE. Sean’s career focus is with sustainable envelopes as he actively pursues this research through a book authorship called, “ENVELOPE TOOLS”.

Whole Building Commissioning
Location

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

Presenters
Medgar Marceau
Description

Whole-building commissioning is a process of quality assurance in building construction. It is a systematic process of ensuring, through documented verification, that building systems are installed and perform according to the documented design and the owner's operational needs. The process starts at the project Design Development stage and continues through staff training, pre-warranty inspection and completion of the wrap-up Commissioning Manual. This presentation will describe the commissioning process developed by ASHRAE in Guideline 0: The Commissioning Process and NIBS in Guideline 3 Exterior Enclosure Technical Requirements for The Commissioning Process. Emphasis will be place on the importance of the building envelope in whole-building commissioning.

Meeting Title
Super Insulating Glazing and Window Technologies
Location

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

Presenters
Brandon Tinianov
Description

In the recent construction economy, high performance new building construction has been complimented with prominent energy efficient retrofit projects. In both categories of construction, improved building envelope design and materials are needed to achieve energy savings goals. One important envelope element is a new class of glazing that has entered the market. So-called “super insulating glass” is capable of attaining high thermal resistance by combining a variety of high performance components. Today’s designers can now choose from an expanding range of high-performance glazing systems and technologies including: improved low-e coatings, high performance films, novel spacers and more. This next generation of windows has full frame R-values of 5 to 10 with a similar cost basis to traditional glass packages. These may be installed as replacement glass or in addition to the existing system. As a result, traditional metrics of economic viability and payback periods must be revised. This presentation is a review of key technologies in the field of advanced windows.
