Durability and Moisture Management (DU)
An important aspect of building a sustainable home is ensuring durability throughout its life cycle. EarthCraft House recognizes that proper design and installation are integral to building a durable home with minimal moisture management issues. Reducing the life cycle costs due to maintenance, repair and replacement decreases the impact that home construction, and reconstruction, have on the environment. The durability and moisture management section includes items that improve long-term durability, occupant health and comfort.
