Which energy-related LEED credit encourages the installation of efficient HVAC systems?

The credit that encourages the installation of efficient HVAC systems is Optimized Energy Performance. This credit aims to improve the energy efficiency of a building's systems, which includes heating, ventilation, and air conditioning (HVAC).

By focusing on optimized energy performance, this credit promotes strategies that reduce energy consumption while maintaining occupant comfort. Efficient HVAC systems are essential in achieving energy savings, as they typically account for a significant portion of a building's energy use. This credit also encourages energy-efficient design and operational strategies throughout the building, striving for improved performance over standard practices.

Enhanced Commissioning, while important for ensuring that building systems are designed, installed, and calibrated effectively, does not specifically emphasize the installation of efficient HVAC systems in the same way. Energy Management focuses on ongoing practices for reducing energy usage but does not explicitly advocate for the installation of new energy-efficient systems. The Energy Star Program is related to performance standards and labeling but does not directly promote system installation within the context of LEED credits.
