Manufactured homes come in all shades of colors, but the most important is "green," as in environmentally friendly. Builders of manufactured homes generally don't waste a lot of building materials, and whatever scraps they do end up with are often recycled. Modular construction allows builders to use less material without compromising a building's structure [source: Gorman].
Even investor Warren Buffett has gone green when it comes to modular home building. In 2009, one of Buffett's companies, Clayton Homes, a subsidiary of Berkshire Hathaway, unveiled its line of green modular homes known as the i-house. With a price tag of less than $75,000, the 750-square-foot (69.6 square-meter) i-house has low-flow faucets, high-efficiency heat pumps and roofs designed to collect rainwater. The i-house saves energy, water and reduces carbon emissions. The i-house is so eco-friendly that it achieved a Platinum rating -- the highest mark possible -- from the Leadership in Energy and Environmental Design (LEED) program run by the U.S. Green Building Council [source: Lawrence].
