ISO-50001 ENERGY MANAGMENT SYSTEM
The ISO 50001:2018 Energy Management System (EnMS) Standard, which replaces the ISO 50001:2011 standard, defines an energy management system as a set of interrelated elements to establish energy policy and objectives and processes and procedures to achieve these objectives. Many industries, including manufacturing, commercial buildings, utilities, government facilities, and military bases, use ISO 50001 to increase operational efficiency, save energy and reduce costs.
Continous İmprovment Model
The ISO 50001 framework ensures that energy-related interests are prioritized and integrates with a continuous improvement model and smart technologies that enable data use and control of energy use.
The model is divided into four phases: Plan, Execute, check and act. Each of these steps has additional tasks that companies should highlight:
Plan: Companies need to understand the relevant requirements, get commitment from management, set energy and flexibility goals, and structure an energy team to meet ISO 50001 requirements.
Apply: People on the energy team need to know where energy is being used and who is using it most, where the company is most vulnerable, and create a list of energy opportunities based on the first three items.
Check: This includes prioritizing energy upgrades, reviewing energy data, and performing internal audits. It also requires the team to meet the reporting requirements.
Take Action: This final step compares energy use across the team, identifies variables that affect energy use, evaluates energy billing and supply, and ensures appropriate operations and management.
Business reasons to enact ISO 50001
Today, energy management is an area of increasing interest and concern to companies around the world due to its potential to control costs, improve energy efficiency, improve environmental quality and increase a company’s overall competitiveness. Using energy smarter and better can increase a company’s overall profit.
The ISO 50001 international energy management system standard provides organizations with a proven approach to developing an energy management plan that addresses critical aspects of energy performance, including energy use, measurement, documentation, reporting, design and supply practices, and other variables that affect energy management.
The adoption of ISO 50001 is important for establishing a systematic and sustainable approach to the management of energy within a facility. Compliance with the standard demonstrates that a facility has implemented sustainable energy management systems, completed the foundation of energy use, and is committed to continuous improvement in energy performance. The value of certification will be driven by market forces in supply chains, potential benefit incentive programs requiring ISO 50001, and the standard’s relationship to future carbon reduction policies.
A DOE analysis found results from 10 ISO 50001 certified facilities:
Cost savings of $36,000 to $938,000 per year
12% reduction (average) in energy costs within 15 months of first application
Energy performance improvements of 5.6% to 30.6% over three years
Savings of $430,000 or more each year from low or free operational improvements.
ISO 50001 Advantages
ISO 50001 EnMS requires skills from two different communities: management system auditors and energy efficiency professionals. Management systems professionals are often unfamiliar with energy issues, and energy efficiency professionals are often unfamiliar with management system processes.
Energy efficiency professionals lacking the skills to implement a management system risk installing an ineffective EnMS without a top management-based continuous improvement process. Management system auditors, who lack the necessary skills to evaluate an organization’s continuous improvement in energy performance, certify organizations without measurable energy performance improvement.
