During the past 20 years, the building sector has seen a significant shift around the use of continuous insulation (CI). Evolving from what was once perceived as an advanced greenbuilding, high-efficiency option, CI is now a standard method and materials practice across most climatic regions. This course will discuss what continuous insulation is, the driver behind its rise, performance benefits, codes and standards, and current material solutions.
For the past decade plus, energy codes continuously increased their requirements for energy efficiency of buildings. Codes began by increasing insulation requirements and recently added an air barrier requirement to reduce air leakage of conditioned air.
The codes include prescriptive and performance requirements; however, the prescriptive requirements are what most designers utilize. Following the prescriptive requirements without consideration of the environmental conditions, both exterior and interior, can result in unintended performance of wall and roof systems. This article will discuss the current state of the code requirements, both prescriptive and performance, as well as when prescriptive requirements may result in inadequate performance.
Building science is an integral part of what builders use today as tools to achieve a better performance building. To achieve a better performance building, builders understand the value of building science and understand that building science will help them achieve building code targets.
Air sealing is now an important part of achieving energy efficiency, and choosing the right insulation is key to achieving air tightness and performance. To reduce air infiltration and achieve an energy-efficient building, the gaps in the building’s thermal enclosure must be sealed properly.
In today’s residential marketplace, air sealing has become a fundamental part of the home building equation, so knowing where and how to air seal will save you money, time and resources on a job. Recent data from a comprehensive industry study has yielded new insights into the role of air sealing in high performance building that can equate to savings for builders and homeowners.
Wall assembly components such as CI and WRBs are now required across the country, requiring in-depth understanding of wall systems. Improper design of transition details can lead to detrimental and expensive issues in wall assemblies. This course reviews building science fundamentals for complete wall systems with CI and WRBs, important considerations when designing transitions and penetrations, and common issues that arise from errors in sequencing, material compatibility and design verification.
Green building is about architectural and human performance and LEED v4 and other green programs can drive market transformation. This course demonstrates how LEED requirements are changing to increasingly emphasize materials and health, and how new credits with higher standards for health and performance are raising the bar for project teams and the sustainable buildings they design. Case studies where insulation products were used in green buildings will be discussed.
