2019 Building Tours: MGM National Harbor

By Better Buildings Beat Team on Jul 30, 2019

On July 9, D.C.-area properties opened their doors to 2019 Summit attendees to showcase their stand-out energy, water, and renewable efficiency measures. Below are highlights from one of the tours.

MGM National Harbor is a 3-million-square-foot, LEED Gold-certified waterfront resort destination in Prince George’s County, Maryland with a casino, luxury hotel, restaurants, shopping, and performance spaces. The tour began with a brief overview from Mark Campbell, Executive Director of Sustainability for MGM Resorts International, who detailed the multi-use property’s environmental features including energy-efficient building systems, occupancy comfort controls, and wellness-minded material selection. Attendees were then escorted to the back-of-house to view the resort’s combined heat and power (CHP) plant, one of the largest privately-operated CHP plants in the D.C. area, capable of producing 750 kW of electricity. The cogeneration system provides onsite power and the exhaust heat is used for both domestic hot water and to drive an absorption chiller, which provides cooling to the building.  Hosts explained that the system is used to reduce energy usage while balancing a comfortable guest experience. 

MGM National Harbor also maintains a 700,000-gallon rainwater recovery system for irrigation and flushing, as well as a host of native plants between the resort and the Potomac River to reduce runoff. Attendees toured an unoccupied guest room and experienced some of the built-in efficiency features, such as the InnComm thermostat that regulates temperature set-points based on occupancy and guest preferences. Architectural features such as the brise soleil and fritting on glass windows help reduce solar heat gain for better managing in-room temperatures. The guest room’s interior finish products, such as paints, sealants, adhesives, and flooring elements, have low Volatile Organic Compounds (VOCs) concentrations, contributing to the overall guest well-being and comfort.
