Mohegan Sun

Balancing “A World at Play” with Sustainability & Environmental Objectives

Aircuity Case Study: Mohegan Sun

There are a million ways to shine at Mohegan Sun, which was created in 1996 by the Mohegan Tribe. It is one of the world’s most amazing destinations with some of New England’s finest dining, hotel accommodations, retail shopping, live entertainment and sporting events. Boasting three world-class casinos, Mohegan Sun is also host to the Kids Quest/Cyber Quest family entertainment facility, a luxurious day spa, convention center and meeting facility, a state-of-the-art Poker Room as well as three major entertainment venues with seating from 300 to 10,000. People from across the globe come to see live concerts with some of today’s top headliners, along with major sporting events including Mohegan Sun’s very own WNBA team, the Connecticut Sun.

Behind the scenes, there is a lot of hard work that goes into creating a 24 hour, 7 days a week entertainment destination that is clean, comfortable, and enjoyable for guests and employees alike. At the same time, the Mohegan Tribe is sensitive to environmental concerns, and they have implemented many green initiatives over the years to reduce energy, eliminate waste, and recycle responsibly. Notable achievements include the use of recycled materials, hybrid fleet vehicles and bicycles, green cleaning practices, forestry donation, and the installation of fuel cell power systems to minimize green house gas emissions.


One aspect of Mohegan Sun’s green initiatives is to improve the energy efficiency of their facilities. The challenge is to find ways to maximize energy efficiency without sacrificing the indoor environmental quality of the resort. One way that Mohegan Sun achieves this balance is by implementing a ventilation solution known as Demand Control Ventilation, or DCV. The concept of DCV is straightforward: determine the number of people that are in each area and then adjust the ventilation rates accordingly. During busy times of the day ventilation will increase to provide more fresh air to guests, and when occupancy declines, ventilation is reduced, saving energy without negatively impacting the indoor environmental quality.

Aircuity’s approach makes it cost-effective for us to measure many different critical parameters within the casino and make smart decisions about the ventilation control. -Daniel Webster, Chief Engineer, Mohegan Sun

While traditional DCV technologies would measure the amount of indoor CO2 in an area to determine occupancy and ventilation rates, and then adjust the amount of fresh air provided to that area based on that measurement, Mohegan Sun, with the help of Aircuity, takes DCV to a whole new level by sensing the total indoor environmental quality. Aircuity’s unique approach senses CO2, particulates, and total volatile organic compounds (TVOCs) that negatively impact the indoor air quality and adjusts ventilation rates to ensure energy savings and maximum occupant comfort. “We want to make sure that we are providing the optimal amount of fresh air based on everything that’s in the air, not just based on the number of people,” explained Daniel Webster, Chief Engineer at Mohegan Sun. “Aircuity’s approach makes it cost effective for us to measure many different critical parameters within the casino and make smart decisions about the ventilation control.”

Aircuity securely stores the data captured by the OptiNet® system and makes it available to Mohegan Sun facilities personnel for review thru a secure web portal. If there are reports of uncomfortable conditions within the facility, the time period in question can be located, graphed, and reviewed to gain insight into the nature and severity of the issue. This information can also be exported into other data analysis tools or reports, making it easy to share up to date information about the facility’s indoor environmental quality.


Energy efficiency projects create the “greenest energy of all”—the energy that never gets used at all. At Mohegan Sun, implementing Aircuity in the Casino of the Earth has lowered ventilation rates and saved the energy needed to heat and cool that air. Over the past year, Mohegan Sun has saved an estimated $74,000 in heating and cooling utility expenses. Based on these savings, the project paid for itself in 20 months. Mohegan Sun is now expanding this “Healthy DCV” solution in the Casino of the Sky and the Casino of the Wind.

Our first priority is to provide a great indoor environment for our guests; it’s great that Aircuity can help ensure this and lower our energy consumption at the same time. – Daniel Webster, Chief Engineer, Mohegan Sun

The Mohegan Tribe’s dedication to sustainability dates back to 1994−two years before the resort was opened− and their commitment is as strong today as it was nearly two decades ago. Mohegan Sun is proof that organizations can be sensitive to environmental issues while still maintaining high standards of quality for their guests. Aircuity’s demand control ventilation solution is just one way that Mohegan Sun saves money, reduces energy consumption, and lowers its carbon footprint without sacrificing the comfort of the occupants of their facilities.
