If there are discrepancies between projected energy use and actual use, identify the cause and follow the M&V plan for corrective action. Discrepancies may result from inaccuracies in the simulation model, actual building use that differs from anticipated occupancy, improperly functioning equipment, and switches and controls not being properly calibrated.
The facility manager should be involved in the decision of whether to select light timers or automated blinds to comply with interior lighting requirements. Both solutions offer opportunities and challenges during building use, depending on how the building is used and occupied.
Timer controls and automatic switches should be commissioned and inspected for performance periodically throughout their life to ensure they continue to serve the intent of the credit requirements.
CO2 sensors and outdoor air flow monitors will need recalibration and maintenance, which will bring a minimal additional cost. If they are not recalibrated, there is potential for overventilation or underventilation, and consequently, unnecessary energy consumption or reduced indoor air quality.
