Until now, factors including the economic sector, number of employees or complexity of a company's energy management, which derives from total energy consumption, relative shares of energy sources and other factors, were used as the basis for determining auditing times required for certification to ISO 50001. These factors give rise to a base time of two auditing days for initial certification of industrial companies and one and a half days for non-industrial energy management systems.
ISO 50003 omits this division. This standard gives more weight to company-specific conditions that influence energy performance, such as the number of significant energy consumers like machines or climate control systems. Moreover, only personnel with a significant influence on energy consumption are now considered, instead of all employees. These factors ultimately yield an auditing time of at least three days for all companies. For you, this means increased time expenditure but at the same time, the opportunity to discover additional potential through the closer look into technical details. This has changed:
- New methods for calculating audit duration
- Basic audit increased to three days
- Additional costs, but also new opportunities for companies
