Event Description

Designing and constructing airtight houses and buildings allows for projects that need less heating and cooling. As a result, it is less costly to attain zero carbon as proper air sealing saves energy and results in smaller mechanical equipment. Achieving super airtight assemblies is about the correct mind set as well as proper protocol and materials. This class will allow you to acquire the knowledge and skills needed to achieve your project's air sealing goals. Terry Nordbye will demonstrate step by step procedures and materials to air seal a new construction house, including Passive House, to virtually any airtightness and achieve deep reductions in retrofit work. You will be shown all steps from planning to construction and learn why, where, and when to air seal.

Learnig objectives: 

• Select the airtight layer (ATL) and maintain the ATL surface throughout the entire job
• Achieve super tight air sealing in new construction or retrofit, in any type of wood frame building or house
• Choose durable materials and select the most appropriate product for any specific location
• Establish accountability and determine who is responsible for the final test
• Explain how airtight buildings make attaining zero carbon status cheaper and easier
