2) Whole Leakage Air Barrier Testing of High Rise Buildings

 

Mitigating Thermal Bridging with Fluid-Applied Coatings

Abstract

It has become more and more evident that the performance of the building envelope can be greatly affected by thermal bridging. This presentation will discuss the use of fluid-applied coatings as a new and innovative solution to minimize thermal bridging in both new and existing buildings. We will cover some key areas of concern where a fluid-applied coating can be utilized without altering the structural design elements of the building and help in saving the owner/end user time and money.

Learning Objectives

  1. Provide an understanding of aerogel particles, fluid applied insulating coatings, and their ability to help reduce condensation and inhibit moisture buildup inside walls to prevent extensive damage and toxic mold formation.
  2. Explain areas within a building interior and exterior where thermal bridging is a concern.
  3. Demonstrate the benefits of using a fluid-applied coating to help address issues with indoor air quality and provide a solution for thermal bridging.
  4. Discuss standards which address the need for continuous insulation (i.e. ASHRAE 90.1-2010).

Presenter: Andy Hoffman | Director – Insulation and Specialty Products | Tnemec Company, Inc.

Whole Leakage Air Barrier Testing of High Rise Buildings

Abstract

Over the past decade, energy codes have brought a number of changes with respect to improving the performance of the building envelope both in design and construction.  Most notable is the increasing importance placed on air-leakage through the enclosure and how this often unknown value affects many of the energy efficiency metrics that define the performance of the building.  Currently, there are multiple codes and standards requiring varying levels of air tightness as well as varying performance levels and methods of verification. As the requirements and performance implications become better understood, common design and construction practices will experience shifts toward better performance as was experienced in the early years of the USACE requirements on which the private sector codes are based.

Through a review of multiple case studies of current enclosure consulting and whole building  air leakage testing, including military, multi-family, and historic renovation, but focusing on high-rise structures this presentation will discuss these codes and standards for validity, impact and relevance.

Learning Objectives

  1. Understand the impact that Air Barriers have on Energy use of a Building
  2. Understand the importance of proper Design of Air Barrier Systems in High-Rise Construction
  3. Understand the importance of proper Construction Quality Control of Air Barrier Systems in High-Rise Construction
  4. Understand the importance of proper Performance Verification Testing of Air Barrier Systems in High-Rise Construction
