The facility is 4,800 sq.ft. In total, River Run's energy-efficient equipment saves 45,283 kilowatt hours annually and, in turn, prevents 77,451 pounds of pollution. Several features attribute to these savings. The building has extra insulation in the walls and floors and insulation blankets are wrapped around water heaters. Williamson installed a programmable heating and cooling system and chose energy-efficient indoor and outdoor lighting.
All guest rooms have variable speed reversible ceiling fans.
All of River Run's double-paned, tinted windows keep solar heat out in the summer and prevent indoor heat from escaping in the winter. Many know that River Run is famous for its gardens and landscaping, but many are not aware of the energy-efficient aspect of the gardens. The gardens are created by a landscaping technique called xeriscaping that requires very little watering.
