Building Science Days | How Buildings Age and How to Fix Them - Day 2: Building Retrofits: Applications and Practice

AIA CES: 7.5 LU | 7.5 HSW

When: 8:30 AM - 5:00 PM THURSDAY, SEPTEMBER 14

Where: At The Center   

Join us for two consecutive seminars by renowned building scientists John Straube and Joe Lstiburek.

Straube and Lstiburek will will help us to understand old buildings and present repair and rehabilitation options. The focus will be mass walls constructed from brick and stone and plaster with the occasional segue to wood frame and timber frame. Old buildings working as a system will be emphasized and the effects on that system by the introduction of insulation and modern materials will be discussed.

Existing buildings and old buildings follow the same laws of building science as new buildings. Most new building and retrofit projects do not follow science, but standard practice and available technology. As expected problems arise and can be particularly frustrating in old building renovations. Understanding how old buildings work and the differences in materials and assemblies allows one to use the science of water, air, vapor and thermal control to avoid expensive future failures and repairs.

This seminar will investigate how to assess the enclosure loads as the start of any condition assessment and retrofit design, and then investigate how old building enclosures provided the control functions (although sometimes poorly). This then leads to how to approach the retrofit and upgrade of typical enclosure walls and roofs. The interaction between mechanical system design, the enclosure design (including windows) and space use will be discussed with the aim of avoiding problems, ensuring comfort, and unlocking cost savings.

Speaker: John Straube, PhD, PEng, Principal, RDH

John Straube is a Principal at RDH’s Toronto and Waterloo offices. Straube heads forensic investigations and leads research projects in the areas of low-energy building design, building enclosure performance, hygrothermal analysis, and field monitoring of wall assemblies. He is also a prolific writer, a noted public speaker, and a sought-after “performance coach” who helps other professionals coordinate their efforts and achieve higher levels of performance in their building projects.

In addition to his work with RDH, Straube is a cross-appointed faculty member in the School of Architecture and the Department of Civil and Environmental Engineering at the University of Waterloo. He was a Principal at Building Science Corporation from 2006 to 2013, and is the co-author, with Eric Burnett, of Building Science for Building Enclosures, one of few texts available with a specific focus on the principles of building science. Straube’s leadership as a building scientist and an educator has been recognized with multiple awards, including the Lifetime Achievement Award in Building Science Education from the National Consortium of Housing Research Centers (NCHRC).
