Strategic Evaluation of Sustainable Practices for HVAC Systems in Small and Medium-Sized U.S. Manufacturers

This paper investigates the often overlooked yet crucial role of Heating, Ventilation, and Air Conditioning (HVAC) systems in advancing sustainable manufacturing practices in the United States. Through all outcomes of the energy assessments conducted by the Industrial Assessment Centers (IACs) in various industrial settings, the current study focuses on the energy consumption of HVAC systems and assesses the impact of their energy-efficient measures on the overall industrial energy usage. In-depth analysis covers both technological and economic facets of resource management practices, utilizing case studies and data from energy assessments on 20,818 small- and medium-sized manufacturing facilities. The results reveal substantial potential for reducing energy consumption, estimated at 71.9 million MMBtu per year, along with annual energy cost savings of approximately $744 million per year and a noteworthy mitigation of 8.7 million metric tons of CO2 emissions per year, all achievable through HVAC system improvements. These findings show the practical significance of sustainable HVAC practices and their potential to improve energy efficiency and mitigate the environmental impact within the manufacturing sector.
