Portland, OR 97204

Presenters: 

David Fookes, Morrison Hershfield

Description: 

Below grade waterproofing is becoming increasingly important as occupants, owners and warranty providers are less tolerant to water ingress into below grade structures and local jurisdictions are increasingly limiting rain and storm water discharge. There are various water management methodologies and waterproofing systems available to provide protection against water ingress of foundations. This presentation provides insight into various waterproofing strategies and systems for below grade foundations. Factors that contribute to the performance of a dry below grade foundation will discussed including soil retention, ground and surface water flow rates, hydrostatic pressure, dewatering and drainage, foundation forming, concrete mix design, steel reinforcement, waterproofing membrane and accessories, weather during installation, contractor experience, design, details, field review and cost.

Presenters: 

John R. Kouba, Malarkey Roofing

Description: 

Chapter 15 of the IBC and the Oregon Specialty Structural Code addresses the code requirements for the design and construction of roof assemblies. Ranging from slope requirements to requirements regarding specific roofing types, including thermoset, thermoplastic and SBS roofing materials, this section of the code is not frequently discussed or referenced during the course of project design and delivery. Mr. Kouba will address these requirements as well as looking at both the requirements and methods for compliance for meeting wind loads and edge securement. Mr. Kouba will clarify what Class A, B and C roofs are and what the criteria are for UL or FM listed roof assemblies. In addition, specific aspects of the code that address the requirements regarding vegetated roof gardens will be discussed.

John Kouba is the Director of Technical Services at Malarkey Roofing, a position he has held since 1998. Prior to that, Mr. Kouba was the Technical Services Manager at US Intec from 1993-1998.

Ventilation in Multi-Family Buildings

Location: 

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

Presenters: 

Lorne Ricketts

Description: 

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.

Lorne Ricketts is a building science engineer (EIT) specializing in research and investigation work. His experience consists of a wide range of projects including: building enclosure condition assessments, forensic investigations, building monitoring, field review, building modeling, and laboratory and field testing services.

Lorne’s Master’s research at the University of Waterloo focused on airflow in high-rise multi-unit residential buildings and included extensive testing and monitoring of a case study building. As a result, his work has developed the industry’s understanding of airflow in and around buildings and how it affects both energy consumption and indoor air quality.

Lorne’s practical experience combined with his theoretical training and proficiency with state-of-the-art thermal and hygrothermal (heat, air, and moisture) software modeling tools has enabled him to evaluate a wide variety of enclosure systems. This analytical work is used as the basis for recommendations regarding air barriers, vapor barriers, insulation levels, thermal bridging, and window selection.

Lorne has a B.A.Sc. in Civil Engineering from the University of British Columbia, BC, and an M.A.Sc. in Civil Engineering at the University of Waterloo, ON.

Validating the Performance of Integrated Facades—EGWW Federal Office Building Case Study

Location: 

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

Presenters: 

Mark Perepelitza

Description: 

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. The presentation will summarize a range of validation methods including material testing, test bed studies of assemblies, and verification of specific simulation methods. The focus of the presentation will be on a case study of the post-occupancy evaluation of a completed federal office building—EGWW. Validation of post-occupancy performance provides important feedback for further commissioning to fine tune building controls and other systems, and also provides a valuable feedback for improving future work by the design team and other professionals.
