Funding Opportunity: Building America Industry Partnerships for High Performance Housing Innovation

PROJECT OBJECTIVE

This project will develop wall system design guidance for builders. It will also improve methods for assessing and improving moisture durability of envelope assembly systems. The objectives of this task are to:

  1. Demonstrate moisture performance of well-designed, high-performance walls
  2. Identify wall systems with marginal performance and develop solutions that increase moisture durability
  3. Develop a set of design criteria, including documentation in support of code change proposals for updating prescriptive moisture management provisions in the International Residential Code (IRC) that ensure durability of high-performance walls

This is one of three Home Innovation Research Labs projects focused on advancing solutions for moisture-managed, high-performance envelope systems in three climate zones: hot/humid, mixed humid, and cold.

PROJECT IMPACT

By improving the way that high-performance building envelope systems function in climates that are widespread across the United States, this project will help produce future homes that are more comfortable and durable at a lower cost.
