Concurrent Evaluation

For the Ameren Missouri BizSavers Programs, we perform pre-installation review of select large non-residential Custom and Standard Program projects to provide early information regarding project energy savings estimates. For lighting controls, to determine the baseline lighting hours of use, we install monitoring equipment to collect sufficient data with which pre-implementation lighting annual hours of operation may be estimated. For HVAC projects, we review applicant engineering energy savings methodologies and, when available, review the inputs of building energy model simulations. We frequently attend pre-installation site visits with program staff to verify baseline HVAC equipment operating conditions and to identify the presence of any operating schedules from existing building management systems. For select large projects, we attend pre-installation site visits with program staff.
