Audit of Energy is an elaboration containing both an analysis of energy consumption, condition of the object, technical equipment or installations and a list of proposed improvements of these objects, equipment or installations, as well as information about economic costs and potential energy savings. A list of proposed improvements must be made with a good understanding of functions and purposes of specific objects, equipment or installations.


Regardless of business sector, in every company it is possible to optimize energy consumption of any form. Due to improvement of energy efficiency, energy demand reduction is achieved, resulting in energy cost savings. Another way to improve energy efficiency is to increase production output of a factory at similar level of energy consumption. Improvement of energy efficiency causes increased profitability of the company.

The audit can be carried out in order to take decision on investment, or after an investment in order to verify its effect. Most often audits are ordered by industrial or manufacturing companies and other companies with relatively high energy consumption, as well as companies following own sustainable energy and environmental policy but also by properties administrators or public institutions.
Depending on the type and scope of coverage, Energy Efficiency Audit in business company contains a list of proposed actions to increase energy efficiency, usually together with an estimated payback period for each one.

Examples of proposed actions include:
• cost-free actions, such as: change of directions of use of an equipment, replacement of energy suppliers.
• low-cost investment, for example: application of thermal insulation for pipes and valves, installation of metering and energy management systems for managing performance as well as efficiency and product quality in the enterprise.
• major investments, eg.: modernization of machines and manufacturing systems for more efficient production, lighting retrofit, thermo-modernization, implementation of new technologies
According to the worldwide trends and international law (eg.: 2012/27/EU DIRECTIVE) there are opportunities created to partial return of costs of energy efficiency improvements. Those are energy savings (color) certificates as well as other benefits such as grants and preferential loans.
