PM Springfest: WHO’S SUPPOSED TO PAY FOR THAT? Managing Capital Budgets & Projects in Mixed-Use Developments


PM Springfest brings together building owners, operators, developers and property managers for a full day of education sessions! Seminars from leading experts focus on how to reduce operating costs, capital projects and budgets, cost-effective maintenance solutions, and more! We’re excited to be participating in this year’s session! This year’s PM Springfest will take place on Wednesday, March 27 at the Metro Toronto Convention Centre’s South Building.

Amy Heppler, Principal / Building Science Engineer, will present Who’s Supposed to Pay for That? Managing Capital Budgets & Projects in Mixed-Use Developments. This session will begin at 8:30 a.m.

More information and registration can be found here.

Presentation Overview:

Mixed-use developments sound great! Condo residents can pop downstairs to the grocery store, office workers have a food court handy for lunch, everyone can access the subway easily through a tunnel, and that parking garage has space for everyone! Property Managers know the reality though – no matter how much thought the Developer put into the documents, you’re always finding new grey areas, and projects no-one budgeted for. This session will examine the special challenges of capital work in mixed-use developments where ownership boundaries are unclear, responsibilities are shared, and access sometimes requires easements. The presentation will examine typical areas of overlapping use and benefit and different ways of budgeting for and managing shared repair and replacement projects.

WABO Annual Education Institute: Air & Moisture Barriers


The Washington Association of Building Officials (WABO) annual Education Institute training sessions will take place March 25-28, 2019 in Lynnwood, Washington. Our team is excited to take part in training the state’s Building Code Officials on the building envelope!

More information and registration can be found here.

Medgar Marceau, Principal / Senior Building Science Engineer, will present Air & Moisture Barriers: What to Look for in Drawings and On Site.

Presentation Overview:

The presentation will review the purpose of the building envelope and describe the concept of continuous control layers to protect the building envelope. We will describe the building envelope control layers for controlling water penetration, air leakage, heat flow, and water vapor diffusion. Emphasis will be on “continuity” of the control layers, what to look for in the drawings and in the field to verify that continuity of the control layers has been maintained. Numerous construction details, material samples, and construction photos, will be used to show examples of the concepts. This presentation will explain the difference between air barriers, water barriers, and vapor barriers and show how the design of the envelope can incorporate some or all of these functions into a single material. We’ll also discuss implication of improper placement of control layers or consequences of improper material selection.

This session will take place during the afternoon session on Tuesday, March 26.

CSC Building Expo: The Building Envelope as a System – A Balanced Approach


We’re excited to be presenting at this year’s CSC Building Expo in Toronto! This year’s conference will take place on Wednesday, February 27, 2019 at the Metro Toronto Convention Centre South Building.

More information on the conference and registration can be found here.

Presentation Overview: The Building Envelope as a System – A Balanced Approach

One fundamental method to achieve deep green buildings is to optimize the envelope’s mechanical and electrical systems. The envelope should be considered as a system where heat, light and air flow in both directions, not viewed simply as a barrier between the interior and exterior. The envelope can be designed to reduce energy loads and impact health and productivity through natural light and control of indoor environment. This can help achieve credits across multiple LEED categories.

This presentation will review the impacts and opportunities associated with the building envelope when pursuing a deep green building. The presentation is based on our experience with multiple large Canadian commercial buildings, each targeting net zero carbon. We will present a methodology to use parametric analysis with whole building energy modelling to explore and understand the energy and carbon impacts of envelope options. The methodology and tools are straightforward and easily understood by architects and owners, and can enable designers to invest more wisely in their envelope. Our presenter will provide attendees with a better understanding of how the envelope can contribute to energy reductions.

This session will take place on Wednesday, February 27 at 3 p.m.

Presentation Overview – Performance Anxiety: Confessions from the Building Envelope

How does the design of the building envelope actually perform? This program will explore this question and show a comprehensive depiction of building performance as it relates to the building envelope. The innovative strategies presented will analyze the relationship between building envelope assembly, materials, and detailing and the actual performance of the envelope assemblies observed from in-field observations and performance testing. The performance aspects related to the building envelope will address water penetration, condensation, thermal performance, and air leakage. This will help designers make informed decisions as well as identify and assess areas of high priority earlier in the design process when it comes to meeting project performance goals. With experience working on hundreds of Building Envelope Commissioning (BECx) and envelope testing projects over the last decade, we have seen what works and what doesn’t. Our in-depth discussion of recent architectural concepts will compare design/details versus actual field performance.

Upon completion of this program, participants will be able to:

  • Outline advanced techniques to develop and evaluate architectural detailing concepts related to air, moisture, and thermal performance
  • Identify effective and progressive methods to accomplish building envelope mock-up and field performance testing
  • Specify performance testing to effectively verify the OPR
  • Describe how products and architectural details actually perform when tested through review of case studies

This session will be presented by Stevan Vinci, Building Envelope Commissioning Specialist, and Rick Ziegler, Senior Building Science Consultant. It will take place on Wednesday, October 3 at 9:20 a.m.

GlassCon Global: Quality Assurance, Quality Control and Quality Fade


GlassCon Global is North America’s premier Technical Conference, bringing together global innovations in glass technology to further the development of the glass and glazing industry. Our team is pleased to have two papers accepted at this year’s GlassCon Global Conference in Chicago, September 5-7, 2018.

Further information and registration can be found here.

Session Overview: Silicone Spandrel Glass Coatings: Mitigating Glass Breakage Risk from Thermal and Other Stresses

Curtain wall design commonly uses insulating glass units for vision and spandrel glazing to provide better visual harmonization of building façade glass. Risks with this design approach include higher thermal stresses, especially when low-emissivity coatings are used on insulating glass units in spandrel areas. Ceramic enamel frit – commonly used to opacify spandrel glass – is known to induce a bending strength reduction of up to 50%. The ability of ceramic enamel frit coated glass to resist thermal stress is similarly reduced. Multiple incidences of thermal stress related fracture have occurred with heat-strengthened, ceramic enamel frit opacified spandrel glass. An increased chance of spontaneous breakage, by nickel sulfide inclusions, may occur if ceramic enamel frit opacified spandrel glass is fully-tempered to withstand the thermal stresses that it is exposed to.

Silicone spandrel glass coatings have been examined as a solution to prevent the strength reduction in heat-treated glass when ceramic enamel frit is applied as an opacifier. Four-point bending tests were used to investigate the flexural strength of coated heat-strengthened and fully-tempered glass. Ball drop testing was used to investigate the impact resistance of coated fully-tempered glass.

Co-Author: Stéphane Hoffman, Vice President, co-authored the paper Silicone Spandrel Glass Coatings: Mitigating Glass Breakage Risk from Thermal and Other Stresses. This paper will be presented by Chris Fronsoe.

Date & Time: Thursday, September 6 at 2:45 p.m.

Session Overview: Quality Assurance, Quality Control and Quality Fade

The need to demonstrate fiscal responsibility for public and private sector building projects typically drives owners, construction managers and general contractors in North America to consider cost savings available through the global supply chain. Global procurement is often relied upon for curtain wall, window wall and other fenestration systems and components. Global procurement has its opportunities and risks. Opportunities include reduced product cost and fabrication capabilities that are not available, or have only limited availability in North America such as jumbo-size low-emissivity coated glass and insulating glass units. Risks include language and cultural differences and long distance communication across many time zones causing confusion in design, ordering, delays in delivery, and problems with product quality. Nevertheless, the fiscal advantages can be considerable.

Ensuring acceptable quality off-shore products is not just a matter of writing into a specification a requirement to comply with applicable building codes, standards and industry practice documents. These technical documents contain surprising limitations and omissions so that despite best efforts, a Quality Assurance (QA) plan and Quality Control (QC) program may not achieve the desired quality outcome. Even if initial product quality samples and production are correct, quality may diminish over time, an effect known as Quality fade (QF).
To be fair, QA, QC and QF can be an issue with domestic producers also. The same latitude in industry practices and standards available to off-shore suppliers is, of course, available to domestic suppliers. So whether or not fenestration systems are globally or locally procured, the building owners, the design team and the construction team should be aware of omissions and limitations of industry practices and standards to avoid unexpected surprises too late in the construction process to make changes.

Presenter: George Torok, Building Science Specialist, will be presenting his paper Quality Assurance, Quality Control and Quality Fade: An Alphabet Soup of Compliance Standards is not Enough. This paper was co-authored by Yvon Chiasson, Building Science Specialist.

Date & Time: Friday, September 7 at 1:30 p.m.

Facade Tectonics Forum VANCOUVER: Beyond Glazing + Big Glazing


Join us at façade Tectonics Forum in Vancouver! We’ll have two team members participating in panel discussions titled Big Glazing: The Escalating Challenge of a Centuries-long Trend and Beyond Glazing: Trends, Drivers and What Lies Beyond the Horizon. This Forum is a full-day symposium, providing several educational sessions focused on the evolving considerations and practices of building façade glazing.

Registration information for Façade Tectonics Forum: VANCOUVER can be found here.

Big Glazing – Presentation Overview:

The trend of ever larger lites of glass in the building envelope extends back to the Roman Empire and the first use of window glass in architecture. Increasing complexity accompanies this trend: larger glazing units are more challenging to produce, handle, transport, support and install. This ongoing amplification of complexity is itself a trend in architectural glass development, which now involves extensive post-processing of raw flat glass by heat treating, coating, laminating, and printing, and the use of glass in an increasing array of complex assemblies including insulating, laminated, photovoltaic, electrochromic, spectrally-selective and decorative products. Where are these trajectories headed? What are the considerations that practitioners must account for in using “big glass?”

Yvon Chiasson, Senior Building Science Consultant, will participate in this panel discussion at 8:15 a.m.

Beyond Glazing – Presentation Overview:

Architectural glass presents multiple trajectories into the future, all with potential contribution to a transformative change in the built environment. These trajectories involve the development of glass as a material and as part of a façade assembly, and the evolution of expression of glass in buildings and their façades—both as a vehicle for transparency, translucency and reflection, and as a performative material facilitating daylight and view. In addition, despite the long-running trends of ever more and ever larger lites of glass in the building skin, escalating performance requirements are driving the consideration and use of alternative façade materials.

Stéphane Hoffman, Principal/VP of Façade Engineering, will participate in this panel discussion at 4:15 p.m.

ASHRAE 2018: Modeling of HVAC Systems Interactions with the Building Envelope


Learn about the ways HVAC and the Building Envelope systems are interconnected and how to efficiently collaborate during the design process in our session Modeling of HVAC Systems Interactions with the Building Envelope at the 2018 ASHRAE Annual Conference June 23–27, 2018.

Presentation Overview:

A building’s HVAC system and building envelope are intimately linked. Many envelope systems used for new construction and retrofit have poor thermal performance characteristics which can impose unexpected limitations on interior environmental set points and thermal comfort. Climate and indoor air moisture conditions can create high risks for building systems. Early collaboration between HVAC and envelope designers will enable the selection of systems and operational requirements that can mitigate problems, improve durability and ultimately result in a better performing new or retrofitted building.

Peter Adams will be presenting at 8 a.m. on Monday, June 25 as part of Seminar 25 in room 371AB.
