Architectural Sheet Metal: Lessons Learned by a Third-Generation Tradesman

November 11, 8:30-9:30 AM

Prior to becoming a building enclosure consultant, Raymond spent 17 years working as an architectural sheet metal worker in Louisville, KY. During this time, significant detailed information was derived from other industry professionals, time at the bench, as well as significant field experience with snips and soldering irons in hand. This experience—coupled with the last ten years as a building enclosure consultant—have given the presenter unique and well-rounded architectural sheet metal experience. While many in the industry proclaim elevated levels of sheet metal expertise, it is apparent during design peer review of these assemblies and numerous sheet metal installations that the skills needed for proper design and installation are lacking. The purpose of this presentation is to share the presenter’s experience and pass on both time-tested design nuances and installation techniques that will enlighten the intermediate and advanced consultant.

Mold In Office Buildings: It Won’t Go Away

November 11, 9:30-10:30 AM

This presentation is a classic case study of an ongoing problem plaguing many office building facility managers across the country: mold. Although much has been written about this subject, many people in the building profession have little knowledge about why buildings keep filling up with mold, and less knowledge about what to do about it.

In this case study, the presenter will demonstrate the steps necessary to conduct a forensic investigation regarding cause of defective building systems, and review the approach, fact finding, conclusions, and recommendations. The presenter will demonstrate the implementation of antiquated design details in a 45,000-sq.-ft. office building with masonry cladding and standing-seam metal roofing. The building suffered from years of poor performance, poor indoor air quality, and unhappy occupants.

This case study offers insight into reviewing and diagnosing existing construction, including interviewing staff personnel, reviewing plans, as well as reviewing maintenance records. The presenter will discuss the performance of brick and concrete masonry unit (CMU) cladding, through-wall flashing, Kraft facing, and #15 felt as an air barrier and how mechanical systems come into play and interact with the building air barrier and enclosure systems.

Re-Examining the Energy Efficiency of Built-Up Roofing and Modified-Bitumen Roof Systems

November 11, 11:00-12:00 NOON

Built-up roofing (BUR) and modified bitumen (mod-bit) roofing systems represent some of the longest lasting roofing systems available for low-slope roofing. Over the past 20 years, the emergence of cool roofing and its enactment into multiple building codes in many cases has eliminated this roofing option from consideration because these systems typically do not have the required levels of solar reflectance.

Since BUR and mod-bit systems are typically ballasted with aggregate for ultraviolet (UV) protection of the asphalt, they are much heavier than their counterparts. With areal densities from 7-10 lb/ft2, the role of thermal inertia could provide a significant contribution to the energy savings of the building enclosure. Since the late 1980s, ASHRAE Standard 90.1 has given an energy credit to wall systems that have thermal mass. In the early 2000s, research demonstrated that ballasted roofing systems are more energy efficient than their lightweight counterparts, given equivalent applications. Aggregate is also available in a wide range of colors that can enhance BUR and mod-bit systems in reflecting solar load.

This presentation will report on a series of in-situ experiments that were designed to measure the energy performance of BUR and mod-bit roofing systems. These data were then used to calibrate a transient thermal model for roofs and to generalize the findings to the range of climates found in the U.S. Comparisons of their energy performance are then made to other traditional low-slope roofing systems.

Importance of Air Barrier Material Properties by Material Category: What You Need for Them to Work

November 11, 1:30 – 2:30 PM

Air barriers are critical to the performance of buildings. Originally siloed as an energy-saving material, they are now being recognized as impacting the total performance of buildings, including moisture management, sound control, HVAC, and other components.

Given a material that affects building assembly performance so directly, what is an air barrier material and what are the key requirements of each category of such materials? What are the different categories and types of air barrier materials currently on the market?

Requirements go beyond the maximum air flow rate, as other properties are critical. The material must perform as intended for its expected life.

Materials must be assembled to work together. Site audit reports from the last 17 years and industry research have prompted the development of material specifications for each category of air barrier material.

On the Weakening of Weathered Window Glass and Its Effect on Human Impact Resistance: Two Fatality Case Studies

November 11, 2:30 – 3:30 PM

Older buildings face a heightened safety risk at windows because weathered glass is weakened against human impact. Magnifying this hazard is the additional factor that many buildings predate building codes that specify safety glass at floor level.

These risk factors came together tragically in two separate fatality matters studied by the author who served as an expert witness. The fatalities were a two-year-old boy and a 30-year-old woman. In each case, victims broke through weathered window glass and fell from heights to their deaths.

To understand the extent to which glass weathering was a factor in the deaths, the author adapted a safety glazing test method to find the impact force at which the glass was no longer a fall barrier. Weakening of the weathered glass was found to be significant.

Test results, building codes, safety glazing codes, historical approaches, and ASTM E1300 will be discussed.

Open for Business—Overcladding Strategies for Institutional Buildings

November 11, 4:00 – 5:00 PM

Institutional buildings, such as research buildings, university classroom buildings, or courthouses, have stringent operational schedules that almost always prohibit disruptive activities and greatly complicate construction. At the same time, these buildings have rehabilitation needs like any other commercial structure—requiring, after decades in service—major renovation work to upgrade exterior masonry façades, fenestration, roofs, and mechanical and life safety systems. One leader of a prominent aviation museum likened this unwelcome but necessary work to “working on an airplane in flight.”

Drawing on their own experience working on the rehabilitation of major institutional buildings and focusing on early-to-mid 20th-century masonry construction, the presenters will discuss technical approaches to masonry whole-façade replacement while keeping a building fully operational. The presentation will cover structural engineering, building enclosure design, energy efficiency improvement, constructability, and logistical and economic aspects of overcladding projects.

ASHRAE 90.1 and Cold-Weather Condensation

November 12, 8:15 – 9:15 AM

To comply with the energy code, designers often utilize the Prescriptive Building Envelope Option described in ASHRAE 90.1 when determining the minimum amount of insulation required within a wall assembly. In cold climates, the minimum R-Value requirement for framed wall assemblies allows designers to utilize a split insulation arrangement to meet code requirements. However, these designs often carry an elevated risk of condensation that is not explained in the text of the standard and may lead a designer to unknowingly promote detrimental insulation combinations with regard to convective condensation.

A design tool has been developed based on psychometrics and ASHRAE 90.1 requirements that illustrates the ratio of continuous insulation to total insulation. The design tool currently assumes a high leakage rate; therefore, values along the pass-fail line may be overly conservative. In order to incorporate a more realistic air leakage rate and develop a more defined pass-fail criteria, our research uses software tools such as WUFI® to study the requirements offered by 90.1 to evaluate the hygrothermal performance of insulation combinations for framed wall assemblies based on the simplified exfiltration model. Hygrothermal engineering principles and the results will be presented with future publication of the design tool for the design industry.

Building Science and Physics vs. Architectural Sensitivity; Design of Enclosures in the Most Hostile of Environments

November 12, 9:15 – 10:15 AM

Background:
Architectural design and sensitivity to skyline views and noise concerns for penthouse unit occupants impacted the original design of the cooling system on a high-rise, leading to placement of the cooling towers in the basements of the east and west wings. Eleven-story air shafts facilitated the cooling tower exhaust, as well as the parking garage ventilation. Organic growth and saturated drywall were observed, giving rise to an investigation.
Evaluation:
A fire-rated shaft assembly was determined to be woefully inadequate in reconciling the vapor drive and water management issues associated with the extremely high humidity and the temperature differentials across the enclosure. Physical configuration and a lack of thought led to systemic water and air leakage through the enclosure wall. Full shaft wall replacement was required.
Design:
WUFI® analysis was used to validate the design concept using an exterior insulation approach, coupled with a redundant vapor barrier system. Further complicating the design were extreme vapor pressure differentials and flow reversals, as well as structural issues related to concrete deterioration and post-tensioned concrete pocket protection. Design provisions also included data logging, and a tattletale system to monitor for bulk water infiltration was designed into the enclosure system.

The Physics Behind Lessons Learned in a Full-Size Blindside Mock-up

November 12, 10:45 – 11:45 AM

Burying a pre-applied waterproofing system between an earth retention system and newly installed concrete—never to be seen again—creates a difficult scenario whereby designers, manufacturers, and contractors are left to wonder just how well their system will perform. SmithGroup (an architectural engineering firm) partnered with a design-build contractor to develop a new university laboratory building. The building included two stories of below-grade construction and was placed at the corner of the project site close to the intersection of two streets. Based on previous success, the design-build contractor proposed the use of a specific blindside system. For the proposed system to be approved for the project, both parties agreed to perform an evaluation. A significant part of the evaluation process included the assembly and forensic deconstruction of a full-size structural shotcrete mock-up.

There are three areas of concern typically posed to all pre-applied waterproofing membranes:

  • Does the system bond to the concrete?
  • Will the system survive the installation of the structural shotcrete?
  • Can the system resist lateral water migration?

From the lessons learned during the assembly and deconstruction of the mock-up, we will review the findings and use scientific methods with applied physics to evaluate the original assumptions and validate the findings.

Thermal Enhancements for Aluminum-Framed Curtainwalls: a Practical Perspective

November 12, 1:15 – 2:15 PM

Aluminum-framed curtainwall systems have many positive traits, though they have historically been underachievers with respect to thermal performance. Developments in recent years have improved the options and performance available on the market. This presentation will discuss various modifications that may be made to aluminum-framed curtainwall systems to improve their thermal performance. We will discuss enhancement options for both the glazing and framing systems, such as the addition of non-metal pressure plates, gas-filled insulating glass units, warm edge spacers, and other available features. We will discuss how these thermal enhancements may affect the thermal performance of the system and will also touch on related design considerations, such as weatherproofing, durability, expected service life, and other factors.

Reroofing an Icon Is a Moving Target; A Case Study of the Reroofing of the Rogers Centre

November 12, 3:45 – 4:45 PM

Assessing, designing, and overseeing the roofing replacement of a retractable roof stadium is an uncommon project. The Rogers Centre, originally named the Skydome, is currently home to the Toronto Blue Jays Major League Baseball team.

The climate and location implications of this project were also unique. Rogers Centre is located on the north shore of Lake Ontario. The 1800-foot-tall CN Tower is immediately adjacent and hovers above the roof surface. Ice “missiles” breaking off from the tower have historically impacted the roof surface. These factors influenced the design of the new roofing system.

In this presentation, we will discuss the challenges and complexities encountered during this project, which began in the assessment phase. 3-D laser imaging, infrared thermography, cores, and exploratory openings were employed to determine the extents of membrane and substrate damage, the location of moisture infiltration through the original roofing membrane, and membrane attachment detailing at edge conditions.

Due to the geometry of the roof and its location, the roof sees harsh winter conditions for several months. Ice and snow collect and settle at the gutters, putting significant stress on the eaves. In addition to updating and strengthening the eave design from the original, a customized snow melt system was designed and installed.

In this presentation, these and other challenges encountered throughout assessment, design, and construction oversight will be discussed.

Building Envelope Commissioning: The Missing Link for Future-Ready Buildings

Thursday, September 13, 8:30 – 9:30 AM

Global climate trends are clear: more extreme weather events, frequent and more intense rain events, and widely variable ambient temperatures. How do current building envelope design practices and retrofit strategies respond and how do we embed this future thinking into our projects?

Building Envelope Commissioning can provide the framework to facilitate conversations about ever-more-stringent standards, processes, codes, and performance requirements related to the building envelope. It also provides a process to ensure performance is embedded in project requirements and is delivered at each stage through construction completion.

This session will use project examples that demonstrate the application of commissioning principles on new construction, existing buildings, or individual enclosure elements – from below grade to the roof and beyond. We will discuss typical design-, tender-, and construction-phase practices that track and test enclosure performance while keeping project teams informed of how value engineering, change management, or substitutions may affect performance. Lastly, we will connect and compare these project examples to common industry guidelines and standards such as LEED v4, LEED EBOM, BOMA BEST, NIBS, ASHRAE, CSA, and ASTM to highlight the need for industry standardization.

Measured Drying Ability of Compact Low-Slope Roofs

Thursday, September 13, 9:30 – 10:30 AM

In conventional compact, low-slope roofs, insulation is sandwiched between two vapour-impermeable layers: on top, the roof membrane, and underneath, the concrete deck or metal deck (with an additional air- and vapour-retarding membrane). This approach can be problematic should water get into the roofing assembly—either during construction, due to a roofing membrane leak, or from air leakage from the interior.

RDH Building Science Laboratories recently completed Phase 1 of an experimental program involving three compact, low-slope roof assemblies on metal decks that were constructed side by side in a field exposure facility in Waterloo, Ontario (Climate Zone 5-6). One assembly was constructed as a reference or base case, with two vapour barriers. The two other assemblies were designed and constructed to allow drying by vapour diffusion, to either the top or bottom side. All three assemblies were subjected to periodic wetting by the injection of controlled amounts of water, and moisture movement was tracked using embedded moisture, temperature, and relative humidity sensors. It was found that the roof assembly with a high vapour permeance membrane on the metal deck (i.e., the inward drying assembly) was most effective in drying water following each intentional wetting. Implications for design and construction will be discussed.

Thermal Performance of Building Enclosures: Where, What, When, Who, How, and Why

Thursday, September 13, 11:00 – 12:00 Noon

Recent evolution of building codes across Canada has certainly raised awareness of effective thermal value for building enclosures, and accurately determining this value for various assemblies is becoming a hot topic. Thermal performance requirements in building codes are generally well defined, but the industry is still learning how best to incorporate these requirements into the design process. Ever-changing and increasingly stringent code requirements also mean the goal posts are not set: regular adaptation is required. This presentation will provide clarity on these issues by answering the following questions:

  • WHERE in Canada are there established enclosure thermal performance requirements?
  • WHAT standards and codes have been adopted in different Canadian jurisdictions?
  • WHEN should effective thermal performance be introduced in the design process?
  • WHO is responsible for confirming that the thermal design is code-compliant?
  • HOW is compliance confirmed and documented? This will include discussion surrounding the available methods of determining effective thermal performance (i.e., 1-D calculations, 2-D and 3-D computer modelling, and physical testing) and their comparable levels of accuracy.
  • WHY does all this even matter?

Roofing vs. Masonry – Who Wins?

Thursday, September 13, 1:30 – 2:30 PM

Historically, the performance of mass masonry wall construction relied on the ability of the system to absorb and release moisture through cyclical wetting and drying. In the era of mass masonry construction, the most prevalent roofing systems consisted of built-up, well-bonded, highly redundant membranes. Contemporary construction relies on a cohesive building envelope to provide a continuous barrier at both the roof and walls to prevent moisture and air infiltration to the interior. This evolution in construction methodology—a drive to “tighten-up” existing buildings—has resulted in challenging design, detailing, and construction approaches when reroofing existing historical buildings. Combining the skills, experience, and knowledge of roofers, masons, and design professionals into one team that is aware of the intended design goal supports the comprehensive development of effective, long-lasting details, and applicable installation and integration of roofing and masonry wall systems.

The authors will illustrate these themes with a discussion regarding design and installation of roofing systems on the back side of parapet walls and other masonry wall/roof interface issues. They will utilize case studies to provide examples of design and implementation challenges for new roofing systems and their interfaces with masonry walls. Challenges for reroofing include the integration of various roofing materials to provide a watertight system when installing to masonry and smooth-glazed terra cotta, and providing an integral water/air barrier when replacing an entire roof structure.

Liquid-Applied Air Barrier Systems for High-Rise Buildings: Code Requirements and Performance Testing

Thursday, September 13, 2:30 – 3:30 PM

Air barrier systems (ABS) are specified in Canadian codes to minimize the infiltration and exfiltration of air through the building envelope in order to control the risk of condensation. However, since the publication of the Energy Code of Canada in 2014, more attention has been drawn to the importance of an air barrier system to control the loss of energy. Recently, the Canadian Construction Material Centre (CCMC) developed performance criteria for liquid-applied ABS, including installation, barrier, and durability criteria. The CCMC is a recognized body that provides guidance to building officials with respect to the National Building Code of Canada (NBC) and the evaluation and testing of innovative products as alternative solutions meeting the requirements of the NBC. The performance criteria for an ABS will be of interest to air barrier material and air barrier system providers, architects, industry consultants, and contractors.

Design of Sloped Roofs in Snow Country

Thursday, September 13, 4:00 – 5:00 PM

The Canadian building codes provide requirements for the minimum structural standards to which roof assemblies in high snow load locations need to be designed. However, the building codes (Part 9 in particular) do not include specific requirements for design of these roofs for resistance to water ingress and resistance to damage caused by snow movement. Based on the number of failures the authors have reviewed, we suggest that design changes are required.

The presenter will discuss common problems caused by high snow loads, snow movement, air leakage, and the often-associated ice damming and water ingress. He will also discuss solutions that have been implemented. Comparison of monitoring results from a repaired and an unrepaired roof assembly (within the same residential complex) will be used to illustrate the importance of airtightness in reducing the temperature of roof assemblies and mitigating the resultant ice damming.

The presenter will also introduce the concept of “double-drained” sloped roof assemblies and discuss a case study where this approach has been successfully used to eliminate a systemic water-ingress problem at a high-end residential home located at a Canadian ski resort.

Whole-Building Airtightness Testing of Industrial, Commercial, and Institutional Buildings

Friday, September 14, 8:15 – 9:15 AM

This paper will address whole-building airtightness research carried out by the Building Envelope Technology Access Centre (BETAC) of Red River College, Winnipeg, Canada. Over the last five years, BETAC has tested over 50 large, commercial-style buildings ranging from 100-year-old churches to new schools. The goal of this work has been to establish baseline air leakage rates, and to compare pre- and post-retrofit airtightness rates to better understand the effectiveness of air leakage sealing in these types of buildings.

The results of this research were also used in the development of a new test procedure developed by the Air Barrier Association of America (ABAA). This led to the creation of ASTM WK35913 “Standard Test Method for Determining the Air Leakage Rate of Large or Multi-zone Buildings,” which introduced improvements from existing test methods to overcome restrictions on building height and climate conditions, and led to the creation of two distinct test procedures which focused on building durability and energy performance, respectively.

In Canada, building officials are starting to incorporate airtightness requirements into regional codes in locations such as Vancouver, Toronto and Manitoba. Also, the introduction of the National Master Specification on Building Enclosure Performance Testing and Commissioning now includes Whole-Building Airtightness Testing. This paper will conclude with a discussion of what the leakage rates should be for Canadian buildings.

Benefits of Dual-Barrier-Protected Membrane Roofs

Friday, September 14, 9:15 – 10:15 AM

Roofing membranes within a roof assembly are generally the only barrier to keep the elements out. Standard building cladding design recognizes that well-performing walls consist of layers of materials (zones) to resist wind, heat, rain, etc., to achieve the rainscreen principle in wall cladding. This dual-barrier design can be applied to roofs.

Protected membrane roof (PMR) assemblies can have superior performance over conventional roofs since the moisture-resistant insulation protects the primary roofing membrane from the environment. Dual-barrier design can be implemented to help reduce negative effects of water diffusing into the insulation or reducing the thermal performance by flowing underneath. Typical PMRs can be easily upgraded by the placement of a properly selected vapour-permeable drainage layer above the insulation.

In addition to reviewing the design considerations for a dual-barrier PMR, attributes of these systems will be reviewed, with case studies comparing PMRs to typical protected roofs.

Strategies for Effective Building Retrofits: Façade and Core

Strategies for Effective Building Retrofits: Façade and Core

Friday, September 14, 10:45 – 11:45 PM

As buildings age, and standards for energy efficiency and carbon reduction increase, retrofit solutions must address both the skin and core of buildings. Façade retrofits (recladding or over-cladding) are often responses to deteriorating cladding elements, inefficient envelopes (thermal, moisture, etc.), aged materials, and/or aesthetic concerns. Recladding a building can increase thermal performance while increasing airtightness. Likewise, building core retrofits are responses to demands for more energy-efficient buildings with a lower carbon footprint.

The Roadmap to Retrofits in Canada (by CaGBC) provides recommended actions to achieve Canada’s net energy-reduction targets by 2030, two of which include recommissioning and deep retrofits. As consultants, we have the opportunity and responsibility to approach emission reduction and envelope performance as one.

The Hudson’s Bay Tower (401 Bay St.) and 120 & 130 Adelaide St. W. (Richmond Adelaide Centre) are examples of tower retrofit projects underway to improve building performance in conjunction with improvements to the buildings’ mechanical systems. Future recommissioning will give owners an opportunity to consider re-cladding along with core retrofits to achieve energy reduction targets.

Advanced planning, research, design, and coordination with all teams will achieve a well-performing whole building system – façade and core.

The Future of Building Envelope Inspections

Friday, September 14, 1:15 – 2:15 PM

The presentation will cover the use of unmanned aerial vehicles (UAVs) for building envelope applications and will focus on rotary vertical take-off and landing (VTOL) aircrafts. By gaining an appreciation of the benefits of deploying UAVs, stakeholders in the building envelope sector will have a better understanding of how this technology can be used to save time and money, and mitigate risk when executing visual inspections. The discussion will then move to cover common regulatory hurdles faced when implementing the technology for building envelope inspections and will be supported with case study examples. The current state of regulations governing the use of UAVs for commercial operations will be addressed, outlining the process for receiving the necessary Transport Canada approvals. There will be a brief examination of how regulations are expected to change by comparing the proposed Canadian framework to that which has recently been instituted in the United States. Next, the use of UAV data sets for reporting on the status of assets and structures will be conveyed by examining the different levels of processing. Finally, the presentation will shift to cover advancements in UAV hardware and software developments and how this will impact stakeholders in building envelope technologies and practices.

Humidity and Building Envelope Failure in Enclosed Swimming Pools, Hot Tubs, and Steam Rooms

Friday, September 14, 2:15 – 3:15 PM

High-humidity building enclosures are typically building occupancies where the relative humidity and temperature of indoor air are very high all year round. Building types that exhibit breaches in moisture-, air-, and vapour-control layers in enclosed spaces include: recreational centres, golf clubs, hospitals, hotels, extended care facilities, and rehab centres. Solutions for this building science problem are a topical area of interest as they are not related to mechanical systems.

In this presentation, IRC Building Sciences Group will present our experiences and client case studies focused on humidity and building envelope failure in enclosed spaces such as: swimming pools, hot tubs, and steam rooms. IRC will address their general building sciences findings and present solutions and examples for these types of high-humidity building enclosures that have their building envelope elements linked to exterior ambient conditions for all four seasons.

The challenge for building science engineers is to design for efficient moisture management and building envelope systems, especially for the ambient conditions prevalent during late fall, winter, and early spring seasons. IRC will cover their solutions implemented in the case studies for the following conditions: hot, moist air not adequately dissipating and causing condensation; external weather and internal humidity causing changing building conditions; and the presence of mould and excess moisture on wall systems causing rotting and extensive damage on interior finishes.

Canadian National Standard for the Vegetated Roof Assembly: Field Validation

Friday, September 14, 3:45 – 4:45 PM

The National Research Council of Canada (NRC), as part of a consortium with members from vegetated roof industries and roofing associations, established a national wind resistance standard for modular vegetated roof assemblies (MVRAs), named CAN/CSA A123.24-15, “Standard Test Method for Wind Resistance of Modular Vegetated Roof Assemblies.” Currently, this standard is widely used, on a voluntary basis, by the Canadian roofing industry for the wind performance compliance of MVRAs. The CAN/CSA A123.24-15 was developed based on the extensive data collected on various MVRAs by simulating wind in laboratory conditions.

The standard provides an experimental procedure to determine pass/fail criteria, as a consensus standard will do. From the wind resistance perspective, the standard evaluates the coherent wind performance of vegetated roof systems in regards to determining the uplift rating of MVRAs. CAN/CSA A123.24-15 is a valuable tool for both building officials and MVRA manufacturers to verify and demonstrate wind uplift compliance with the requirements of the building codes. This paper presents the details for CAN/CSA A123.24-15 implementation. It provides the fundamentals of MVRA wind performance, as well as the requirements, scope, and limitations of applying the CAN/CSA A123.24-15. In addition to laboratory results, a field data comparison will be presented as part of the validation process.
