Environmental Sustainability

Ruby Falls' mission to inspire extraordinary connections to nature through wonder and adventure is dependent not just on our ability to protect the precious resources of the Ruby Falls Cave but also the earth’s resources for generations to come. 

As the first attraction in the United States to earn certification from Green Globe, the respected worldwide standard for sustainability, Ruby Falls is a leader in tourism sustainability and environmentally-sensitive business practices. 

Our conservation initiatives are centered on five environmental focuses.

The construction of our new venues and offices are a huge opportunity to incorporating green building techniques, place the new venues sensitively on the land to protect natural habitats, maximize the amount of vegetated open space and utilize storm water management strategies to control the amount of runoff from the site.

Buildings are the single largest consumer of energy in the United States. According to the Environmental Protection Agency (EPA), building usage accounts for 50-75% of all electricity produced nationwide. Much of this energy is wasted due to inefficiencies and typical human behavior. Special attention to energy performance and was prioritized in the design strategies of our new venues. The building was modeled to protect energy performance and is expected to be more than 24% more energy efficient compared to conventional construction. The energy-efficient envelope, low-E windows, and LED lighting and controls, efficient HVAC system and building automation system all contributed to this performance.

Materials and resources were tracked closely during design and construction. More than 75% of all construction waste was recycled rather than sent to the landfill. More than 10% of the materials used to construct the building contain recycled content, and more than 20% of materials were manufactured within a 500-mile radius of the building. Recycled content and regionally sourced materials lessen the greenhouse gas emissions associated with manufacturing and transporting materials. Examples of materials that contain recycled content are steel, concrete, insulation, drywall, access flooring, carpet, acoustic ceiling, tile flooring, and countertops. Examples of regional materials include carpeting, drywall, precast concrete, metal roofing, and acoustic ceiling tile.

Rainwater is captured and filtered in giant tanks under the Village Plaza. This water is used instead of potable water for irrigation at Ruby Falls, this saves more than 16,000 gallons of water annually!

Water conserving plumbing fixtures are installed in all of the new bathrooms and team breakrooms. These fixtures improve indoor water consumption by about 38,287 gallons per year, giving us over 39% water use savings compared to a similar conventional building. That’s about the same volume of about 7 typical swimming pools.

Alternative forms of transportation are encouraged through carpooling of Ruby Falls team members, nearby access to bike paths and electric vehicle charging stations for guests and the team.  Public transit route maps and schedules are accessible with stops just over a half-a-mile away from Ruby Falls. 

The refrigerants used in the cooling and refrigeration systems are not CFC-based which negatively impact our ozone.

Low-emitting paints, sealants, and flooring were used to protect the health and well-being of occupants from the volatile organic compounds (VOCs) that are typically found in these products, which negatively affect respiration. These products were carefully tracked for compliance with strict VOC limits. Interior finishes have been selected for their durability, but also healthy indoor air quality properties. The floor finishes are a mix of low-emitting carpeting and resilient flooring with ceramic tile in the restrooms. Resilient flooring was selected in many spaces for healthy cleaning purposes.  

Air Quality Initiatives

Ruby Falls strictly prohibits smoking within 25’ from venue entrances. 

Healthy cleaning practices are employed to clean effectively without harmful chemicals. 

According to the EPA, people spend more than 90% of their time indoors, where contaminants can be up to 10 times higher than outdoors. Heightened ventilation performance was included in the design of our new venues by installing a dedicated outside air system with CO2 sensors to monitor the airflow in densely occupied spaces.
