Below-Grade Waterproofing in Urban Areas
Building construction in urban areas with high water tables and/or mandated flood plains presents design teams and contractors with unique logistical issues. Difficulties can include site access, material delivery, construction of the structural framing system, cladding, roofing, below-grade waterproofing, and governmental regulations. In an urban environment, where buildings may be constructed with zero lot lines, the basement must be formed by excavating and installing a soil retention system. When below-grade site conditions include excavating through rock or a high water table, the cost of the work escalates rapidly. The presenter will offer case studies of three buildings with basements located in urban areas and how the support of excavation and waterproofing systems evolved.

Proper Design, Installation, and Field Quality Control for Achieving a High-Performance Air Barrier System
Air barrier systems are different from other building envelope components: You cannot see air leakage. Designers must trust that the contractor’s workers will make all the connections airtight in an industry that some say is quick to cover things up so one can’t see the quality of an installation. The speaker will detail steps to reduce risk and improve the performance of buildings, and will discuss what happens if you do not get it right. Many think air barriers simply save energy, but the main reason one installs an air barrier system is to reduce moisture problems –in both warm, moist climates and cold ones.

In-Situ Measurement of Wind Performance of Roof Edge Systems
In commercial roofing, metal edges are the first line of defense against the effects of wind. As part of the Roofing Industry Committee on Weather Issues’ (RICOWI’s) Wind Investigation Program (WIP), North American roofing professionals completed a major fact-finding investigation immediately following the landfall of Hurricanes Charley, Ike, Ivan, and Katrina. Field data clearly supported that the majority of the roof failures were due to the failure of metal roof edges. These findings suggest that current building codes (i.e., NBCC and ASCE) do not accurately specify wind design loads acting on roof edge metal systems. The speaker will present the findings of measured wind-induced pressure acting on all surfaces of three different edge configurations.

Structural Assessment of Glass Restoration
The glass-clad surfaces of building envelopes may be damaged by construction activities, high-wind events, explosions, and façade maintenance or repair activities. In some cases, the affected glass can be restored to an acceptable condition using a combination of wet and dry polishing methods. This polishing treatment removes a thin layer of glass at the blemish locations. Reduction of glass thickness may cause concern for the structural integrity of the glass, particularly with heat-treated glass. Using case studies, the authors will discuss how to assess heat-treated glass restored by polishing.

Optimizing the Building Envelope With a BIM-Based Framework
Imagine putting together a puzzle with pieces designed by ten different companies. The building envelope process is like that puzzle; it is made up of an aggregate of multiple designs coming together for the first time, onsite. Building Information Modeling (BIM) puts all the pieces together virtually so that multiple design elements come together onsite with design mistakes and oversights identified and corrected. In 2015, Zero/Six collaborated with Hensel Phelps to assemble the pieces in a BIM framework to coordinate shop drawings for a 432,671 square feet (sq. ft.) facility.

Reroofing Requirements in the 2015 International Codes
Most (about 75%) of the roof systems produced for use on U.S. buildings end up on existing buildings. Reroofing is one of the most common construction projects. In order to fully understand the code requirements for reroofing projects, it is necessary to review three separate codes. The IBC contains the basic material requirements for roof covering assemblies. Other provisions for reroofing can be found in the International Existing Building Code (IEBC) and the International Energy Conservation Code (IECC). Recent clarifications to the codes for reroofing have improved their clarity, but given the need to coordinate the provisions across three codes, many will benefit from a reroofing review.

Critical Components of Welding Thermoplastic Membranes
Thermoplastic membranes comprise the largest segment of the low-slope roofing market. A critical key to their success is their ability to form a watertight seam, in the field, that will perform over a long period of time. There is a body of research that has focused on “welding windows” and formulation performance, yet critical to fabricating good seams on the roof is having a thorough understanding of cleaning procedures, robotic welding equipment and settings, ambient temperatures, interpreting test welds, and the art of hand welding. While there is much anecdotal evidence of what can affect the ability to field-fabricate seams that perform over the long term, there is a lack of data regarding these key elements vital to the roof’s performance. The speaker will examine the critical components of proper field welding for both PVC and TPO membranes. He will discuss key differences between the two membranes and how roof consultants and roof observers can insure that thermoplastic single ply membrane roofs are welded correctly, regardless of field conditions.

Testing the Potential Synergy of Green Roof-Integrated Photovoltaics at the University of Toronto Green Roof Innovation Testing (GRIT) Laboratory
The 2009 City of Toronto Green Roof Bylaw requires green roofs on all new construction, yet solar and green roof technologies are rarely combined. Combining green (vegetative) roofs with photovoltaic (PV) technology may improve energy efficiency through evaporative cooling, while also providing other benefits such as stormwater capture and improved urban ecology. The speaker’s research investigates the effect of green roofs on ambient temperature, PV surface temperature, and power output. This is the first research of this kind in Canada and will benefit the building industry by producing Canadian-based performance data and generating design guidelines and tools.
