Projects of interest in the United States of America
Space heating and cooling use 46% of all energy consumed in U.S. residential buildings. Benefits of advanced technology do not stop with energy and cost savings, but extend to environmental protection and health. For example, new technologies are minimizing environmental impacts related to refrigerants, and more effective ventilation and space conditioning are demonstrating the potential to enhance the health and productivity of building occupants by improving air quality.
