Energy modeling is still an important tool for energy auditors, but it is becoming increasingly supplemented by data analytics and other methods.

Data analytics can be used to identify energy waste, prioritize energy efficiency measures, and track the progress of energy efficiency projects.

Building performance in energy auditing focuses on both improving the energy efficiency of individual building components and improving the overall energy performance of a building.

Energy audits can be integrated with building automation systems by using the data from the building automation system to identify energy waste and by using the building automation system to control energy-consuming devices.

The increasing complexity of buildings, the lack of qualified energy auditors, and the high cost of energy audits are all challenges facing energy auditors today.
