Intro to Houses That Work
In this session participants learn how the many complex changes in home design, building materials, mechanical systems, appliances, consumer lifestyles and expectations over the last 30 years makes every builders, suppliers and trade contractors job more complex and demanding. The segment outlines the basic building science physics of air, heat and moisture flow that every builder should know so they can understand why some buildings work and others don't.
This NEW workshop explores cost-effective opportunities to implement energy efficient and green technologies and strategies into remodeling projects for existing homes. The fundamentals of building science - air, heat and moisture flow – are applied to help participants understand how elements of a house all work together as a system and how this knowledge can be used by remodelers to reduce risks and find the most cost-effective energy improvements for individual homes.
This workshop will teach participants essential information about air sealing as it applies to single-family residences. The house is a system and every component in it works together. Adding insulation and sealing air leaks can improve the energy efficiency of a home and improve the home’s comfort and durability. However, every change made to the building’s envelope (walls, floors, and ceiling) and components will affect how the home works to keep out the elements and keep the occupants safe and comfortable. Tightening the building envelope without providing appropriate ventilation can cause pressure imbalances or negative pressure in the house. This negative pressure can set up the conditions for back drafting of fireplaces or fuel-burning (combustion) appliances and may draw pollutants into the home. A trained contractor understands how systems work together to keep the house operating as it should. Participants will learn the basics about air leakage and the details and techniques for air sealing. They will gain practical and affordable tools and strategies they can use to help their clients make better decisions. Participants will be equipped to avoid potential risks and identify new opportunities for marketing their services. The information presented in this session will build on the basics of building science covered in the popular EEBA full day Houses That Work session. Participants for this Air sealing session are encouraged to attend a Houses That Work session before taking this workshop.
