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 energy
means saving costs!!“
The path:
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)
Competitive advantages
rational use of energy
via
Background:
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
The ideal energy concept:
6 golden steps …
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
The 3 steps model:
The as-is analysis …
►
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

Example for the use of energy
according to type of disbursement
Energy losses…
► Heat insulation
(building, cables …)
► Climatization
Energy gains …
► Use of solar energy
(Natural illumination, geothermal
heat , photovoltaic, solar heat …)
Co-generation …
● Combustion plant with steam turbines
● Gas turbines, if necessary as gas and
steam plant
● Fuel cells
● Co-generators with gas and diesel
motors
Essential consumers…
►
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
Formulation of
energy saving measures
…
● 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
Possibilities for energy saving …
► 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 heater for foundries
► Application of vacuum heaters for process of hardening
► Heating of steel via inductive methods
Evaluation
of
processes …
● 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
