But it is best to hire experts who will evaluate your energy needs and consumption pattern.
An Energy Auditor studies the various components of your organisation that consume power/energy. The agenda is clear as far as the Energy Auditors are concerned: They are there to (a) Identify the energy wastage in your factory/office and (b) Value the energy so lost.
The energy auditor draws up a plan for efficient energy utilisation for your factory/office. Th audit report lists the areas/components that need to be improved to arrive at a better energy management system. Thanks to the inputs of the Energy Auditors companies are likely to optimise energy use and hence benefit financially as well – both in the short term as well as in the long term.
It is said that the suggestions made by at the end of the Energy Audit typically throws up a savings of 10%-15% to the overall costs.
The Energy Audit is usually treated in three phases: (1) Investigation, (2) Monitoring, (3) Analysis/Reporting.
Let’s have a brief look at three phases.
Investigation Phase: The energy auditor would collect the relevant data in this phase. The kind of data that he/she is in interested in is as follows: Past and present energy consumption (at least for 3 years), energy prices contracts with energy providers, office/factory size, people strength, manufacturing output, working hours, various lighting and other equipment in use (consuming power) and their specifications, current energy management systems and protocols
Monitoring Phase: This is the next stage that the energy auditor embarks upon. More detailed than the earlier phase, your auditor will inspect the operation of the various machinery items and record key performance parameters like the temperature and humidity levels inside the factory, electrical & gas load stats, rate of ventilation and more. The auditor also assimilates information from the employees managing the equipment to understand the operational practices and procedures, and maintenance protocols.
Analysis/Reporting Phase: In this stage the energy auditor looks at the energy efficiency of the building in relation to the production/output, greenhouse emissions, ABGR energy star rating, power tariff, peak demand management.
