Greensburg now has more than 450 high-efficiency toilets from Caroma and is projected to save at least 4,600 gallons of water per person per year. (Many of the city’s buildings were built in the 1960s or earlier, so many toilets were either 3.5 gallons per flush or 5 gpf toilets.)
The Alliance to Save Energy estimates that the average U.S. household spent about $2,350 last year on home energy, and the U.S. Department of Energy says 45 percent of home energy goes toward home heating and cooling costs.
Because they are factory-built, modular homes can take advantage of resource efficiencies that make them less expensive to produce. That involves less waste, which makes it green as well as more affordable.
While a modular or systems-built home is built to the same codes as a traditional, site-built home, the inspector can’t see behind the walls when it arrives at the building site, making the verification process more difficult. By ensuring that the house and its components meet green requirements in the factory through this new program, the rest of the inspection can be conducted onsite.
