Twenty-first Century Townhouses: Video

This video provides an overview of the construction and finish of the Twenty-First Century Townhouses built in the NAHB National Research Home Park. The video details the construction of the townhouses which use four different structural systems-autoclaved aerated concrete, insulating concrete forms, precast concrete walls and light gauge steel frame, and structural insulated panels. It also explains some of the advanced energy efficiency concepts including the photovoltaic roofing system. This is a good companion video to the illustrated guide.
