Industrial Energy Auditing for Increased Sustainability - Methodology and Measurements

Industrial energy efficiency is a key component in the transition of the economy towards in‐ creased sustainability. For an industrial company, there are four means to reduce energy costs: implementing energy-efficient technologies, energy carrier conversion, load management, and more energy-efficient behaviour. The European end-use energy efficiency and energy services directive promotes, among other things, the removal of existing market barriers and imper‐ fections that impede the efficient end use of energy [1]. Energy audits provide an important tool in reducing barriers to energy efficiency [2]. Furthermore, an initial, well-structured en‐ ergy audit is the first important step in a successful in-house energy management program in industry [3].
