The 3 kEys 

• A common rule-of-thumb is that raising the cooling setpoint by 1°F can lead to about a 3% decrease in energy consumption. In practice, this means if you raise the setpoint by 2°F, you might see around a 6% reduction. 

• Regularly verify that supply and return dampers are properly balanced to optimize airflow. Ensure that vents and registers remain unobstructed by furniture or other items to allow for free air circulation. 

• Use economizers to employ cooler outside air for “free cooling” when conditions are favorable, thus reducing mechanical cooling demand. 

Improving HVAC energy efficiency doesn’t always require a major overhaul or significant investment. Instead, a focus on simple, operational strategies can lead to reduced energy consumption quickly and cost-effectively. The following techniques, offer practical adjustments that building managers and facility operators can imple...
