In the last decade, carbon levels increased 20 parts per million (from 380 to 403), the population grew by one billion, global temperature increased by half a degree Celsius, and 25 percent more people moved into our cities.
This lecture will focus on the benefits of building in a dry, controlled environment and how this helps to build better buildings. Focusing on the science of construction, specifically the thermodynamic relationship of a building from inside to outside. Speaking on product integration and the importance of understanding how all the different WRBs, tapes, and sealants work together as well as the importance of mechanical systems and building pressures.
The fluorocarbon-based polymer ethylene tetrafuoroethylene (ETFE) is quickly gaining popularity in North America and is being used on some of the continent’s most prominent projects. Through review of multiple case studies of current ETFE installations, Morrison Hershfeld will review lessons learned and provide an understanding of limitations as well as benefits of the material from a building science perspective.
This presentation will examine recent window and curtain wall assembly failures and performance issues for Insulated Glazing Units (IGU), aluminum coatings, gaskets, and associated water and air leakage issues. With the advent of globalization in the construction industry, façade glazing systems are beginning to experience new types of failure in the components (seals, coatings, sealants, etc.) used to assemble the complex systems and result in performance issues of today’s high rise projects.
This course will discuss the different types of roofing membranes and systems available for low slope/commercial installations and the benefits each brings to the building envelope. Over the past 25 years, there have been many changes in not just the materials available but also the installation methods used to install roofing systems. In addition to the materials, installation methods will be discussed as well as a practical discussion of how to evaluate which option may be better than others for several different scenarios.
The number of passive houses and buildings meeting the stringent PHIUS+2015 Passive Building Standards has increased exponentially over the past two years: first single family residential projects were built, then multifamily projects and now the trend is moving towards commercial structures. Many municipalities such as NYC have already incentives in place for residential passive buildings or are evaluating to implement incentives as a solution to meeting their climate action plans.
The session is a Case Study driven review of façade details for transparent systems. Where many education provide a review of the basic stock details the critical design issues often occur at the atypical conditions. The basic "rules of thumb" do not apply when the geometry or material choice require more from the design. This session will review the atypical conditions that do not occur in the idealized conditions. The course is crucial to those designing the enclosure of buildings that do not fit the mold of a common box.
Air Barriers are an extremely important component of a high-performance building enclosure system. For the most part, these systems are non-maintainable components and repairs can typically only be made with the removal of the exterior cladding system. To ensure a performing system, proper design, detailing and ultimately the proper installation of these systems is extremely important. You have one chance to get it right.
The tragic fire in London, UK, raises issues with respect to claddings and continuous insulation in high performance buildings as well as retrofits. The first part of this session addresses the physics of the fire in London and why such an occurrence is unlikely in the United States and Canada.
