"Does Smart Building Automation Truly Enhance Energy Efficiency?"

September 5, 2024


Building Automation Systems are evolving rapidly, with many Controls & HVAC Contractors aiming to deliver smart solutions. However, it's essential to focus on energy performance during the design and engineering stages. Often, engineers overlook critical aspects of control sequences and their implementation for HVAC equipment, which can significantly impact the system's overall effectiveness.

Here are some common issues:

  1. Plant System Controls: Demand-based controls are often not implemented correctly, leading to inefficient operation of plant systems.
  2. Air Handling Units: Cooling and heating coil setpoints are not adjusted based on zone demand, resulting in energy wastage.
  3. Supply Fan Pressure: The pressure setpoint for air handling unit supply fans is not reset based on trim and response methods, which can cause inefficiencies.
  4. VAV Configuration: Zone VAVs (Variable Air Volume systems) often lack optimal start configurations, impacting energy efficiency.
  5. Cooling Equipment Sizing: Building cooling equipment is not sized based on overall demand, affecting energy efficiency.
  6. Maintenance: Poor or insufficient maintenance practices compromise system performance and longevity.

A well-designed building automation system requires thoughtful engineering to ensure it delivers smart, energy-efficient solutions. Controls and mechanical contractors should avoid these pitfalls in their control’s submittals, application programming, and site implementation to achieve true smart building automation.
