Built in 1986, the Westin St. John has both interval ownership and traditional resort rooms and offers its guests a wide array of activities and amenities. With a year-round average temperature of 85 degrees, a harsh salt water environment and a tropical remote location, operating costs had been escalating for years due to increased energy and water prices.


The Westin St. John Resort & Villas were dedicated to reducing operating costs. TLC was selected to complete an ASHRAE Level 2 energy audit of the entire resort complex to improve its energy efficiency and reduce its operating costs. TLC identified ECMs that would save an estimated $755,000 annually, with an overall simple payback of 2.3 years. Recommendations were made to replace aged equipment, look into a solar domestic hot water system, change the inefficient chilled water energy system from constant volume pumping to variable flor primary arrangement, and more.
