Omnicrete is considered a "Fresh House" according to the American Lung Association - Due to AAC

An additional quality contributing to the sustainability of a building system is its ability to reduce and absorb noise or to improve or maintain indoor air quality. Due to its millions of independent air cells in the Autoclaved Aerated Concrete (AAC) stay in place forming walls, which dampen sound transmission, AAC has excellent sound insulation and absorption qualities. 

Moreover, because Omnicrete construction has NO air infiltration and is 100% mold resistant, indoor air quality of Omnicrete structures is greatly improved relative to competitors. Also Omnicrete's tri-wall system's performance as both a structural and insulation material also eliminates the need for other materials (like fiberglass insulation) that may contribute to poor indoor air quality.
