The EPRI LightPAD program is a simple but powerful lighting audit and analysis tool for assessing installed lighting systems and proposing cost-effective, energy-efficient retrofit alternatives. LightPAD enables on-site data entry to the analysis program, improving both speed and accuracy by removing the step of making hand-written field notes. The data can be checked and validated on-site, and retrofit alternatives compared on-site. Lighting calculations are based on the lumen methodl. Project files containing the total building kW profiles may be exported to EPRI's COMTECHtm program to perform more complex financial. analysis and to integrate the lighting system into a total building systems audit.
