The Energy Systems Laboratory (ESL) was established in 1939 as a test and research facility for the heating, ventilation and air condition industry. For more than 50 years, this independent, certified laboratory at the Texas A&M University Riverside Campus has served air conditioning and ventilation manufacturers across the nation and abroad. The laboratory is the official testing laboratory for the Home Ventilating Institute. Its well-earned reputation -- for tests conducted to industry standards, for equipment traceable to the National Institute of Standards and Technology and for quick response to clients' customized needs -- has made the ESL a preferred research facility among industry leaders. The ESL continues to expand its capabilities and offers a variety of research and testing faculties.
