Jan 2016

APEGBC and BCBEC Event - Vancouver Half-Day Seminar:
Part 5 – Beyond Air, Heat & Moisture

Thursday, April 21st, 2016
The Italian Cultural Centre Society
Vancouver, BC

This half day seminar looks at the Part 5 requirements going beyond heat, air & moisture in the BCBC & VBBL.

Speakers specialized in their respective fields will cover fundamentals and discuss criterias for the structural, acoustic & fire considerations for the building envelope.


Vancouver Luncheon:
R-22 Walls and Insulating for the Future

Thursday, March 17th, 2016
The Italian Cultural Centre Society
Vancouver, BC

About the Presenter: Lorne Ricketts, RDH Building Science Inc.

Lorne Ricketts is a buildings science engineer (EIT) with RDH Building Science Inc. in Vancouver. He is actively involved in forensic investigation, building monitoring, new construction, and research projects. Lorne was recently the primary author for a guide to R-22+ Effective Walls produced for the HPO and the City of Vancouver to help select and design durable assemblies that achieve increasing thermal performance requirements.

About the Topic:  R-22 Walls and Insulating for the Future

R-22 thermal performance is now required by the Vancouver Building By-Law for Part 9 wall assemblies, and R-value requirements elsewhere are consistently increasing as the industry looks to construct more energy efficient buildings. Lorne will discuss various assemblies which meet the R-22 wall requirement without compromising other aspects of building enclosure performance such as moisture management, air leakage, and durability, and will also present the pros and cons of various different cladding attachment options when using exterior insulation.


Half-Day Workshop on Building Smart with Air and Vapour Barriers
Thursday, February 18th, 2016
The Italian Cultural Centre Society

Vancouver, BC
Building Smart with Air and Vapour Barriers Brochure
(Updated February 5, 2016)

Presented by the British Columbia Building Envelope Council (BCBEC) and the Homeowner Protection Office (HPO), a branch of BC Housing.

This half-day workshop focused on the use of air and vapour barriers in single and multi-unit residential buildings. A panel of building envelope experts shared building science principles, design considerations and practical installation details. Speakers examined challenges and options for improving the durability, safety, comfort and energy efficiency of buildings through the effective use of barrier materials.


Vancouver Luncheon:
Mid-Rise Wood Frame Construction

Thursday, January 21st, 2016
The Italian Cultural Centre Society
Vancouver, BC

About the Presenter: Jieying Wang, PhD., Senior Scientist, Building Systems Department - FPInnovations

Jieying Wang is a Senior Scientist in the Structural, Durability, and Sustainability Group of the Advanced Building Systems Department at FPInnovations in Vancouver BC. Since she joined FPInnovations (then operating as “Forintek Canada Corp.”) ten years ago, her research has focused primarily on wood durability, moisture performance, and thermal performance of wood-based building envelopes. She worked with building science professionals in developing durable wall assemblies for cross-laminated timber (CLT) construction to facilitate its use in North America. She has been heavily involved in projects on differential movement in mid-rise wood construction and the application of non-load-bearing wood walls in concrete structures. In recent years she has also focused on thermal and durability performance of the building envelope with increasing levels of thermal insulation. She led the projects in developing two design guides for energy efficient building enclosures of MURBs and high-performance houses. She played an important role in developing the Technical Guide for the Design and Construction of Tall Wood Buildings in Canada, and more recently the Mid-rise Wood-Frame Construction Handbook. Jieying has also been extensively involved in developing durability-related building codes and standards in China and Korea for the export market of Canadian wood products. Jieying obtained her PhD in Wood Science from Beijing Forestry University in China in 2000 and worked at the University of Toronto as a post-doctoral research fellow from 2002 to 2005.

About the topic: Mid-Rise Wood Frame Construction

The growing interest in wood-frame construction as well as the growth in the urban population prompted the regulatory authorities of many provinces to allow taller buildings in areas that were traditionally low-rise construction.

FPInnovations' Mid-Rise Wood Frame Construction Handbook consists of ten multi-disciplinary chapters, which have been prepared to facilitate the design and construction of mid-rise wood-frame construction (5- and 6-storey). The handbook captures in a single document the skills of many experts and specialists, and provides practical solutions by making use of the most recently developed technical and research information to assist designers, architects, and engineers.

The presentation will highlight the required design considerations for vertical differential movement in mid-rise wood frame construction. Field measurement of vertical movement as well as wood moisture content changes is used to validate and improve predictions in design. Detailing at critical interfaces is emphasized to reduce differential movement and mitigate its potential impact.
