This presentation initially took place at IIBEC's 2022 International Convention and Trade Show in Orlando, Florida.  How do you make sure penetrations through your already installed air and water barrier are watertight? The method of sealing of cladding attachments through the wall assembly are critical to the building performance. To create a relevant, data-backed solution, a robust test plan was developed using a statistical test design and implemented to test all the variables of interest. Then, a statistical model was built to predict the probability of leaks with various sealing solutions. The process was used to determine which type of flashing and sealing solution is best to ensure watertightness after cladding attachments are installed over polyisocyanurate insulating sheathing. This presentation shares the basis of the test plan and research methodology as well as the findings on sealing penetrations through this system.   Andrea Wagner Watts, LEED Green Associate DuPont Performance Building Solutions | East Aurora, NY Andrea Wagner Watts is the commercial application leader for DuPont Performance Building Solutions.

This was initially presented at IIBEC's 2021 Virtual Spring Symposium Historic 19th and 20th-century buildings are currently facing the necessity of meeting contemporary needs such as adaptive reuse, energy efficiency, stability, and durability. The characteristics of the architecture of these periods, i.e., material, design, details, maintenance, functionality, increasingly make it challenging to maintain authenticity while incorporating new uses. Various strategies of technical interventions can be employed to achieve good results. Thornton Tomasetti, Inc. will present a case study of an abandoned historic hospital pavilions from the early 20th century which is being converted into a high-end residential complex. The buildings face multiple challenges related to adaptive re-use, as they will be restored and connected with new infills and a glass connector and capped with a re-creation of the historic cornices. The presentation will entail challenges of adaptive reuse through various technologies, leading to the introduction of new elements and retention and upgrade of existing to incorporate new use.

This course is designed for practicing roof consultants, architects and engineers who desire to become more knowledgeable about designing roof drainage systems to be functional and to meet code. Read more

This course is designed for those who design roof systems and for those that need to understand roofing heat transfer and moisture affects on roofing systems.  The skills taught in this course are of use to all those involved in roof performance and are necessary skills for the RRC.  The principles taught have applicability to walls as well as roofs but the primary focus is on roof systems. The content moves quickly beyond basic thermal terminology and calculations to cooling-load calculations, annual energy consumptions and payback calculations, cool roofing, and temperature calculations within cross sections. Moisture starts with the psychrometric chart and moist-air properties. Additional topics include vapor retarders, the effects of moisture on insulation, air barriers, and mold issues. Read more

This is the recorded version of the live two-day course and is a first component of a two-part series covering, in detail, aspects of the technology and science of roofing. It covers the history and evolution of roofing up to present-day common applications. It features terminology and technical information regarding roof decks and structures, roof insulation, bitumen membranes, built-up and modified bitumen membranes and flashing systems. An understanding of heat transfer theory, moisture, thermal design, and the calculation of U-factors will also be presented. Highlights of the program include: critical aspects of roof decking and related supporting structures, heat transfer and practical heat transfer calculations, the function of heat transfer and the different types of roof insulation, the technology behind roofing bitumens and their related BUR and modified-bitumen membranes, and basic flashing nomenclature and bituminous flashing system construction. The Roof Technology and Science I course features fundamental concepts that prove useful for students in other IIBEC Educational Programs. Roof consultants, facility managers, contractors, architects, engineers, roofing material salespeople, property managers and others can gain new insight and professional development in the continually evolving world of roofing technology. This recorded version of the live two-day event is sponsored by GAF. Read more

This is the recorded version of the live two-day course and is the second course of a two-part series covering, in detail, aspects of the technology and science of roofing. Highlights of the program include: fundamentals of single-ply, polyurethane foam, and PMR roof systems; basic concepts and terminology of metal roofing; steep roof design and installation of asphalt shingles, tiles, wood shakes, and shingles; building codes; fire testing/ratings of roofing; a basic understanding of wind interaction upon roofing and typical wind ratings; principles of roof asset management, including roof inspections, maintenance, and nondestructive evaluations. This course is designed to provide individuals of differing backgrounds with relevant information about roofing technology and design. The chapters vary in intensity, from basic roofing concepts to advanced specific-application principles and theory. This recorded version of the live two-day event is sponsored by GAF. Read more
