ASHRAE Standards are guidelines developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers to ensure the safety, efficiency, and sustainability of heating, ventilation, air conditioning, and refrigeration systems. These standards cover various aspects, including design, installation, and maintenance, helping professionals create comfortable and healthy indoor environments. The standards are regularly updated to reflect advancements in technology and changes in industry practices. They serve as a valuable resource for engineers, architects, and building owners, promoting energy efficiency and environmental responsibility in building operations and design.
