* Sustainable bamboo floor entryway. The use of bamboo saves trees because bamboo can be harvested in only three years. Most hardwood trees are harvested after 50 years.

* Recycled content interface Entropy Carpet. This carpet contains more than 70 percent recycled content, making it the highest recycled-content carpet available. At the end of its life, the carpet is 100 percent recycled back into new carpet.

* Dual-flush toilets. Popular in Australia, but still relatively new to the U.S., dual-flush toilets provide two options for flushing utilizing 0.8 gallons or 1.6 gallons per flush, saving 67 percent more water than a standard toilet.

* Renewable solar and wind energy. Zion Lodge uses a 15kW on-site solar photovoltaic energy system to power rooms. Renewable wind energy is also purchased to power 85 percent of the property's energy needs.

* Filtered drinking water faucets. Guests of the suites drink filtered water from clean, natural, great-tasting water from the park. Excellent filtered tap water encourages guests to carry reusable water containers instead of disposable plastic water bottles.

* Organic bamboo or organic cotton sheets and linens. One of the fastest growing and most sustainable plants on earth, bamboo does not require the use of fertilizers or pesticides to grow. And while traditional cotton is the most pesticide-intensive crop grown, organic cotton uses no synthetic pesticides.

* All-natural biodegradable soap, shampoos and moisturizers in bulk dispensers. These products provide a healthy and eco-friendly alternative to individually packaged non-biodegradable amenities.

* Compact fluorescent lighting. Energy consumption is reduced by up to 70 percent and bulbs last 10 times longer than standard incandescent light bulbs.

* Automated heat and air-conditioning sensors. These sensors detect body heat and motion to control the temperatures within comfortable pre-determined set points.

* Biodegradable, non-toxic Green Seal-certified cleaners. These cleaners are used in all Zion Lodge rooms.

* Complimentary organic coffee and tea. Certified organic Fair Trade coffee is grown without pesticides, using a shade-grown method to reduce deforestation. Two complimentary mugs with the Zion Lodge are also given to all Green Suites guests. The free coffee is provided by the lodge coffee shop only to those with mugs to discourage waste caused by disposable coffee cups.

* Key card lighting controls. Similar to popular systems used throughout Europe, key cards save 15 percent of energy because lighting is only operable once guests insert their key cards into the entry door slots.

* NED nightlights. Nightlights discourage guests from leaving bathroom lights on as a nighttime light source.
