Company goals:

Obtain an efficient use for the company of the 3 resources energy, human and machines from an economical and ecological point of view.

“Saving energymeans saving costs!!“

1.) Energy consultation = identification of buildings and include these outcomes into the as-is status, show and explain further steps of action

2.) Heat insulation measures of the envelope

3.) Optimization of the building and heating technology

4.) Consultation for financial handling of a project

5.) Quality control of the services (Quality control methods)

The path:


permanently increasing prices for energy &

growing national as well as international competition

The Possibilities:

● alleviate the demand for energy,

● optimize the application of energy,

● reduce energy acquisition costs

Competitive advantages viarational use of energy

Theideal energy concept:

1.)Recording of the operational energy fluxes

2.)Determination of essential consumers

3.)Rating of the energy consumption of particular machines with comparison figures

4.)Appraisal of alternative machines / procedures for energy saving

5.)Evaluation/feasibility study of the procedures

6.)Choice of the ideal type of financing

6golden steps …

The3 steps model:

► Set up of annual (if necessary monthly) consumption data of the energy sources

► Schedule of supply and disposal costs of the company

► Evaluation and revision of energy delivery contracts , if necessary, improvement of the consumer infrastructure

► Appraisal and valuation of the provision and disposal concept, if necessary, define ideal focal point

► Compilation of first own key figures in order to detect possible weak spots and points of priority of the energy concept

The as-is analysis …

General divisionoperational energy application: (2)

Example for the use of energy according to type of disbursement


► Heat insulation(building, cables …)

► Climatization


► Use of solar energy(Natural illumination, geothermal heat , photovoltaic, solar heat …)


● Combustion plant with steam turbines

● Gas turbines, if necessary as gas and

steam plant

● Fuel cells

● Co-generators with gas and diesel


► Evaluation of regularly collected energy data per energy source

► Compilation of consumption lists on the basis of production chains, distribution networks, machinery lists or plant layout

► Appraisal of existing energy data / measurements of relevant consumers / estimation of energy demand of smallish consumers

► Evaluation of consumers with plausibility control

► Creation of qualitative energy-flow diagrams, which are pointing up the distribution of the respective energy fluxes within a company

Essential consumers…

● Determine basic data of the facilities

● Survey of employees and manufacturers

● Inspection of the load, operation mode and capacity

● Consider alternative methods and machines

● Draft optimization proposals

● Carry out feasibility studies

Formulation ofenergy saving measures …

► Organizational measures (e. g. operation of test beds in times of light load, cut off of machines)

► Process optimization (parameters for handling, alignment of processes)

► Heat insulation of cables and instruments

► Use of waste heat of oven and washings

► Application of medium-frequency heaterfor foundries

► Application of vacuum heatersfor process of hardening

► Heating of steelvia inductive methods

Possibilities for energy saving …

● Determination of possible changes in production, qualities and capacities

● Survey of companies, staff and producers

● Choice of ideal measures

● Determination of energy and cost saving as well as of investments and planning costs of a measurement

● Feasibility study of measures

● Creation of a catalogue of measures including evaluated optimization measures
