Low permeance vapor barriers, once thought to improve performance, may in fact increase interior condensation and trap moisture within the wall assembly. Due to the problems with impermeable water-resistive barrier (WRB) installation many architects are now incorporating highly vapor open WRB systems in their designs. But many still believe too much permeability is bad for a wall assembly. Studies show that highly permeable WRB systems increase substrate drying, reduce the wet time of absorptive claddings allowing permeable WRB membranes to enhance the wall assembly performance. This presentation investigates the current research on vapor open systems and discusses how more permeability enhances wall assembly performance.

Rough openings will leak - learn how to properly sequence rough opening installation materials and allow the “leaks” to drain out and away from the building structure.

Carbon is a buzzword but what does it really mean in practical terms during new construction or renovation? Learn the answers through our informative AIA accredited 3-part series on “Re-Solutions.”

Part 1: A Carbon Case for Building and Material Re-use

Knowing the importance of preserving existing buildings and material, as explored in “Re-Solution Part I: A Carbon Case for Building and Material Re-use” this course will examine which strategies are best for different structures and situations. We will explore different [a host] of scenarios and case studies, with an eye towards the potential for improvement across the board. Carbon (dioxide) is a hot topic these days and will be a companion of sorts, though we will be sure to include H20 (oxygen, hydrogen, nitrogen) since all of these work interdependently in buildings, colluding as an all-too-often overlooked enemy of sustainability: moisture damage. If a building leaks, it is not sustainable. Here we will brush with a broader stroke, emphasizing the need for good design and detailing, while exploring examples of successful wall and roof assemblies. In “Re-solutions III: Facilitating Architectural Re-use and Wiser Wood in New Construction,” we will hone in on specific factors which can help hedge successes and minimize pitfalls in implementing reuse strategies.

As interest in mass timber building design grows, there are new protection strategies that must be employed for a successful installation to ensure occupant long-term health and safety. This presentation will explain moisture protection strategies by providing in-depth test results on mass timber wetting and drying studies, methods to protect during each construction phase, and the vapor-permeable protection technology available to address wood’s unique moisture characteristics. All in an effort to create a sustainable, stable structure and preserve the beauty of the mass timber building.

Based on published studies, a vented rainscreen assembly provides the following for a wall assembly:

• Effectively drain water that has entered behind the cladding

• Reduces the wet time of absorptive claddings

• Increased drying of the interstitial wall assembly

• Mitigate reverse vapor drive for highly permeable Water Resistant Barrier / Air Barrier (WRB/AB) systems

Learn the current research and field practices on vapor open (permeable), vented rain screen cladding wall assemblies and their impact to mitigate water long-term intrusion and enhance the drying capacity of the building envelope assembly for the life of the building.

We will discuss how Polyiso Continuous Insulation will improve the thermal performance of walls of Steel Stud Construction. In addressing the advantages of continuous insulation – we will also address the disadvantages of using steel studs without continuous insulation. We will discuss what Sustainability d how it is measured, including – factors that are involved in addressing Building Longevity – how these concepts impact making buildings more energy efficient. We will look at various types of products that can be used to achieve designs with a perspective that address sustainable construction. Looking towards the future we will discuss the actions being undertaken in conjunction with energy conservation and construction codes, building science organizations and other groups in pushing building envelope design. We will also look at the history of Polyiso and how this product is produced from raw chemicals, creating a completed board stock product.

This presentation originates from a research report written by the Applied Building Technology Group called Assessment of Water Vapor Control Methods for Modern Insulated Light-Frame Wall Assemblies. The report is extensive and includes compiled data from test homes, huts, and studies from the US, Canada, and Europe. The presentation utilizes the collected data from the research report in the form of a table to make easy insulation choices to prevent moisture issues. This presentation will first present the Building Science Concepts one needs to understand why things happen the way they do. The attendee will then be able to use that information to make informed decisions on how to design with wood framed construction. The presentation also breaks down some of the findings about wood sheathing and how it has been standing up over the years.

This course outlines the dangers posed by Mother Nature and the science, codes, testing and methods in which to build and combat these forces. In addition, this course addresses the value of continuous insulation to improve the energy conversation of the building. We will also address how proper incorporation of martials including continuous insulation and air and weather-barrier systems will improve indoor air quality and contribute to environmental sustainability.

An introduction to the history, manufacturing, and use of Polyisocyanurate Insulation in Commercial and Residential Construction and address how these products can contribute to energy efficiency, fire safety, sustainability, and a healthier indoor environment.
