Planners and building users may benefit by incorporating sustainable planning, techniques and products in the creation of new buildings and communities. Restoring existing buildings and properly managing the removal and recycling of materials generated as part of the development process are also important factors that affect sustainable development.

Dewees Island  -  The natural island resources and pristine environment at Dewees Island have been spared the impacts of over development through the implementation of sustainable construction and landscaping practices.  The island, located just north of Charleston, is home to a housing project begun by Dewees Island Development Company.  However, the company undertook the project with the goal of protecting the natural island ecosystem through minimized external intrusion.  They limited development to 150 home sites that would incorporate conservation in land use and xeriscaping to create a manicured surrounding consistent with the natural habitat.  Xeriscaping also preserves groundwater and minimizes the need for fertilizers.  Each home had to comply to strict standards, some of which included structurally insulated panels, rainwater harvesting, permeable pavement, low- VOC paint finishes and adhesives, low-flow plumbing fixtures, small-diameter sewer lines, and shared wastewater treatment systems.  Construction crews are instructed to minimize the amount of lumber they cut, and waste reduction policies are strictly enforced. Electric vehicles are used to travel about the island.  Before construction, the climate was studied so energy efficiency could be maximized through the orientation of the house.  Homes are oriented to collect cooling breezes, have overhangs and use strategically planted vegetation to reduce air conditioning expenses.  92% of the island was conserved and efforts to enhance efficiency netted a total of 60% energy savings, 70% water savings, and 60% household waste savings. Dewees Island Homes are built to exceed Energy Star standards.
