häwa Introduces a Certified Energy Management System

häwa GmbH, the manufacturer of cabinet and enclosure systems, has recently obtained the energy certification to the internationally recognized DIN EN ISO 50001 standard. The certificate which includes the locations Wain, Bad Wörishofen, Crimmitschau, Duisburg and Maintal has a validity of three years and will be monitored by an accredited certification body on an annual basis.

The standard, which has been published in Germany since the end of 2011, aims essentially at purposefully reducing the specific energy consumption and achieving a sustainable increase in energy efficiency in a continual improvement process.
To reach this goal, häwa is using a systematic approach whereby all energy fluxes in the company are measured, monitored and analyzed, all machines, equipment and processes regularly examined for optimization possibilities and the staff involved sensitized and trained accordingly.
The total annual energy consumption of häwa GmbH amounts to around eight million kilowatt-hours with an energy mix consisting of electricity, gas, heating oil and transport fuels. With a share of 65 %, electricity and gas represent the main energy sources for the processes. The Wain location accounts for a total annual consumption of about 4.5 million kilowatt-hours in electricity and gas. The electricity consumption alone corresponds to the annual consumption of 600 4-person households. By installing a photovoltaic unit on the Wain premises, almost one million CO2-neutral kilowatt-hours are now being generated per year.
The new energy management system, whose application is voluntary, aims to achieve a more efficient and sustainable use of the available energy resources as well as a reduction in greenhouse gas emissions (CO2) and other related environmental impacts. Hence, each kilowatt-hour of electricity from conventional power plants, which has not been consumed, means CO2 savings of 0.5 kilogram.
A core element of the energy management system is to continually set strategic and operative energy targets, the implementation and effects of which will be reviewed through internal audits and evaluated and documented in an annual energy efficiency report.
