40% of energy costs in commercial buildings are consumed by the HVAC system. Cutting this in half can reduce total power charges by 20% resulting in significant cost savings over time. Integrating a building automation system for the HVAC can implement predictive and automated controls that will provide both comfort and efficiency. HVAC optimization occurs from gathering real time data from the outside and inside air conditions and using engineered algorithms to determine the ideal operating conditions that balance both comfort and efficiency. These systems can be implemented into existing systems and will usually provide enough savings to cover the upgrade cost in 3 years.
