Surprisingly little research has been done into the effectiveness of different drip edge designs. Drip edges are found at window sills, window head flashing, and the edges of roofs and balconies – all critical areas for managing rainwater. By deflecting rain from the exterior surface of a wall, drip edges can reduce moisture-related issues such as freeze thaw of masonry, staining of the cladding, and potential long term erosion of historical materials. In this session, Jonathan Smegal will describe recent research into effective drip edge design.

Lindsey Pflugrath, an attorney with Skellenger Bender, P.S., will present a case study involving a recent jury verdict in a public, design-build project and catastrophic injuries to a State worker. Ms. Pflugrath will discuss the risks presented by joint venture partnerships on design-build projects, how employer immunity can shift risk to design and construction professionals, the importance of contract-specific contracts, and the new “failure to warn” negligence theory.

The commissioning of a building enclosure is dependent upon the assumption that the construction manager and his contractors have a proactive first level enclosure process fully implemented in order to provide the opportunity for BECx to function and succeed.

A panel discussion that reviews the challenges and opportunities of the Enclosure Development Process. This discussion will include the perspective of the Architect, Contractor, and Owner regarding the successful and “challenged” processes for going through iterations of modifying the Enclosure.

This course will discuss the challenges of current lows-slope roofing applications and further explore the properties of insulation types and performance characteristics under different operating temperatures. Participants will learn of an alternative insulation selection strategy using a hybrid approach combining both polyisocyanurate and mineral wool. Dimensional stability and constructability of the hybrid system will be explored in addition to the implications of roofing color and energy transfer through the insulation assembly.

Cross laminated timber (CLT) is an engineered wood building system designed to complement light- and heavy-timber framing options. Now available to North American building designers, it offers the structural simplicity needed for cost-effective projects, as well as benefits such as fast installation, reduced waste, improved thermal performance and design versatility.

SeaBEC will host its third one-day symposium at the Seattle Art Museum. The theme of High Tech / Low Tech: The Evolution of Building Enclosures will explore a wide range of topics including new building enclosure technologies, biomimicry, kinetic architecture, cold climate design, and life cycle assessment. Six hours of AIA, RCI, and GBCI continuing education credits will be provided (pending approval).

$100 Program Sponsorships are still available.

Integrated building facades have the potential to play a significant role in the support of aggressive building performance goals but validation is critical to assure that the potential is actually realized. This presentation will address the role of integrated facades in significantly reducing energy use while supporting high levels of occupant satisfaction. For transparent facade assemblies, the primary factors affecting performance are the management of solar heat gain, optimizing daylighting while managing glare, visual connections, and thermal transmittance.

Multi-family buildings are commonly ventilated using corridor pressurization based ventilation systems. This presentation will use a recent Pacific Northwest based case study to examine why this type of system is often inefficient and ineffective, and will demonstrate why alternative systems should be considered. Key concepts which will be discussed include the interaction of the ventilation system with building enclosure airtightness, occupants, and natural pressure differences created by stack effect.

This presentation will discuss the basic attributes of different roofing systems and the key considerations to choosing a roofing system.
