Consider the site on which you will build your green hotel. You may want to face or design the building so that it makes maximum use of natural light. You will also want to make the best use of the natural landscape so that excessive amounts of water and chemicals aren't needed for upkeep.Select building materials that do not damage the environment, either through extraction or building. Many companies now market new-growth lumber, so the consumer knows that it has not been taken from old-growth forests. You can also build with recycled materials, such as scrap PVC to make shingles, to lower costs.Use building materials that reduce the amount of heating and cooling needed. Insulated concrete forms, structural insulated panels, autoclaved aerated concrete blocks and high-performance windows help maintain a constant temperature inside a structure, reducing heating and cooling costs.Install sinks, showers and toilets that save on water. Builders can choose from many appliances that use less gallons of water for each use.Use interior materials that provide a healthy environment for visitors. Nontoxic paints, solvents and adhesives can be used in many instances. Build pollutant removers into the ventilation system to aid visitors with respiratory conditions. Choose floor coverings, finish, trim and caulking that have been manufactured using green methods and that provide energy or environmental benefits for your hotel.
