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.

Meeting Title: 

Evaluating the Effectiveness of Different Drip Edge Profiles

Location: 

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

Presenters: 

Jonathan Smegal

Description: 

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. The study he will discuss used a custom-designed apparatus to compare the effectiveness of different drip edge materials, profiles and overhang distances. The results show a significant range in performance. Based on these results, practical guidelines will be suggested for choosing the best drip edge for your project.

Jonathan Smegal’s work for BSCI includes laboratory research, hygrothermal modelling, field monitoring of wall performance, and forensic analysis of building failures. He worked for Balanced Solutions from 2005-2007, joining BSCI in 2007 after finishing his thesis on Drainage in Small Cavities in Wall Systems as part of the Building Engineering Group at the University of Waterloo. Jonathan’s research has included, among other things, cladding deflection tests, drainage balance testing and specialized water uptake and vapour permeance testing. His experience in the lab is complemented by his experience in the field, where he has been involved with forensic work and numerous new construction site audits for residential and commercial construction. As a speaker, Jonathan has addressed a range of audiences at academic conferences, corporate training events, and online. For example, he presented papers at the 2013 Buildings XII Conference and at the 2014 Canadian Building Science and Technology Conference, and has spoken at workshops and other events on diverse topics including cladding attachment, SPF in cathedral ceilings, and rainwater management in wall systems.
