Passing the BPI Exam With Energy Auditor TrainingBPI Written Exam - Section 5 Analyzing Buildings' Systems7. Equipment control strategies for maximizing occupant comfort and minimizing energy consumptionThe HVAC system can be controlled for maximizing comfort and energy savings. You can find the SP chart (fan performance data) found in the furnace cabinet or air handler name plate data and check that the blower fan is set to the correct speed for heating and cooling. For cooling the evaporator coil is designed to operate at peak efficiency with between 350 and 450 CFM per ton of cooling capacity. Most equipment comes with the fan speed set in cooling mode at 400 CFM/ton. The greater the airflow over the coil, the less humidity you remove, so if you live in a dry climate, you can set the fan speed up to as much as 450/ton to get more sensible cooling and less latent. If you live in a humid summer climate, you may benefit from slowing the fan down to as little as 350/ton to improve humidity control in your home. If you go below 350/ton or you can cause the coil to ice because you aren't moving enough warm air over it to keep it from freezing.
