Autoclaved Aerated Concrete: Shaping the Evolution of Residential Construction in the United States

摘要

Precast Autoclaved Aerated Concrete (AAC) is a proven construction material used in Europe for over 70 years. Introduced to the United States in 1990, construction thus far is limited to commercial and custom borne applications. Premium benefits include energy efficiency and resistance to natural disaster and pests. Despite being the leading residential construction material in Europe and Japan, lumber is the leading material of choice in the United States. AAC is clearly a superior residential construction product in its current form, but the economic position of lumber and industry change hesitation demand a different marketing approach than is used elsewhere in the world. Using an internet-based survey, home buyers provide data surrounding three core issues: the important characteristics of a house, how much are they willing to pay for superior benefits, and the expected payback period. Adapting current product form and installation methods can make AAC cost competitive with traditional residential framing systems. Consumer education is essential in this evolution to understand the connection between building products and their benefits. As an option to lumber construction, consumers will benefit from its low utility and life cycle costs. The environment will benefit from its energy efficiency and natural resource conservation.
