An energy audit is an inspection survey and an analysis of energy flows for energy conservation in a building. It includes a process or system to reduce the amount of energy input into the system without negatively affecting the output. For industrial applications, it is the HVAC, lighting, and production equipment that use the most energy, and hence are the primary focus of energy audits. Power Factor improvement is another major concern in the case of a lot of inductive loads connected to the facility. cations.
A detailed financial analysis is performed for each measure based on detailed implementation cost estimates, site-specific operating cost savings, and the customer’s investment criteria. Sufficient detail is provided to justify project implementation. The evolution of cloud-based energy auditing software platforms is enabling the managers of commercial buildings to collaborate with general and specialty trades contractors in performing general and energy system audits. The benefit of software-enabled collaboration is the ability to identify the full range of energy efficiency options that may be applicable to the specific building.
Following are the main process of an Energy Audit
  • Utility bills are collected for a 12- to 36-month period to evaluate the facility’s energy demand rate structures and energy usage profiles.
  • The analysis of building and utility data, including the study of the installed equipment
  • The survey of the real operating conditions
  • the understanding of the building behaviour and of the interactions with weather, occupancy and operating schedules
  • The selection and the evaluation of energy conservation measures (ECMs) were selected to correct the defects or improve the existing installation.
