Use the following to answer the question.
Clayton Homes, a mobile home manufacturer since 1934, introduced its new i-House in 2007. The i-House is one of the first of its kind, designed as an updated, modern version of the modular home, offered as a base home plus add-ons known as "pods." The base home is a one-bedroom, one-bath, 734-square-foot version at a price of around $80,000. There is also a 1,000-square-foot version for around $100,000. All versions may add on the additional one-room pods, which are shipped to your location and constructed on site. The homes offer galvanized metal roofing, corrugated steel siding, VOC-free paints, and a "butterfly" roof that collects rainwater. The i-House uses 30% less energy than a similar square-foot home and offers "green" characteristics of solar panels, tankless water heaters, and low-flow faucets. In addition, it comes with bamboo flooring, a renewable resource. The modular, prefabricated design offers endless options for creating the customer's home, and its engineered building system cuts down on construction waste. Due to the "green effects" of the i-House, the state governments have given it a tax abatement for any sales taxes.
Refer to Scenario 3.2. The i-House's reduction of energy use, renewable resources as materials, "pod" customization, reduction of construction waste, and tax abatement status is/are examples of reaction to which environmental forces?
