• System sizing: Properly sizing HVAC systems to meet the building's heating and cooling loads.
• System efficiency: Selecting high-efficiency HVAC equipment.
• System maintenance: Regularly maintaining HVAC systems to ensure optimal performance.
• Control systems: Implementing smart control systems to optimize HVAC operation based on occupancy and weather conditions.

Example: In regions with hot and humid climates, such as Singapore, energy-efficient air conditioning systems are essential for maintaining comfortable indoor environments while minimizing energy consumption. Building automation systems are commonly used to optimize HVAC operation.

4. Building Commissioning

Building commissioning is a systematic process of ensuring that a building and its systems perform as intended. Commissioning involves verifying that the building design meets the owner's requirements, that equipment is properly installed and configured, and that building operators are trained to operate the building efficiently. Commissioning can significantly improve building performance, reduce energy consumption, and enhance occupant comfort.

Example: The LEED (Leadership in Energy and Environmental Design) certification program, widely used globally, emphasizes building commissioning as a key strategy for achieving sustainable building performance.
