Efficiency Calculation: Providing Clear Evidence of Cost-Effectiveness and Savings

Efficiency Calculation: Your Robust Business Case for Energy and Process Optimization

With the ONI efficiency calculation, you can quickly gain transparency into energy flows, cost levers, and payback periods—serving as a basis for decision-making regarding investments in cooling, heat recovery, and process and energy media. ONI combines operational analysis, planning, and implementation into a comprehensive concept—efficient, transparent, and practical.

  • Measurable: Consumption, load profiles, and savings potential clearly quantified
  • Economic: ROI/payback calculation as a clear basis for decision-making
  • Feasible: Results lead to a viable system concept “from a single source”

Clear & Comparable

Impact of measures on energy consumption and operating costs

ONI views energy efficiency as a strategically important factor that is relevant to audits, particularly in the field of industrial cooling, heating, and media systems. By applying proven methods from energy consulting and operating cost analysis to our areas of expertise, and by integrating our own specialized knowledge, we develop customized energy concepts. These concepts are designed to reduce energy consumption and lower operating costs in a sustainable manner.

  • Operational analyses for cost reduction and identification of hidden efficiency potential
  • Comprehensive system solutions from a single source—from cooling and heat recovery to comprehensive service
  • Innovative, partly patented efficiency technologies (e.g., EtaControl®, PowerSave®, AquaClean®, Rhytemper®) with a special focus on a short payback period
  • Support with subsidies and regulatory compliance, including EnEfG-related data collection and consulting

That’s why you should choose ONI

Structured & transparent

Methodology for calculating efficiency

We combine our expertise in systems engineering and process engineering with a clear approach: We evaluate operational data, systematically analyze and assess potential savings, and present the findings as a basis for decision-making.

  • Current Status Assessment & Target Scenario: Recording energy and media consumption and defining goals such as cost reduction, availability, CO₂ reduction, and compliance.
  • Potential Analysis & Variant Comparison: Identification of the greatest savings opportunities and comprehensive consulting through to a system solution.
  • Cost-Effectiveness/ROI: Development of a management-ready business case including CAPEX/OPEX, savings, and an implementation plan.
  • Concept → Implementation: Development of a practical concept covering planning, construction, commissioning, and service.

Overview of Cost-Saving Measures

Cost-saving measures in ONI system technology
 

Refrigeration (Cooling / Refrigeration Systems)

Cost savings through optimized system design (appropriate capacity, correct temperature differentials), energy-efficient control, free/indirect cooling, and modern components such as variable-speed drives to generate only the cooling required.

Heat (Waste Heat Utilization / Heat Recovery)

Increased efficiency through multiple use of paid-for energy: Waste heat from refrigeration processes, cooling water, or compressed air generation is utilized as useful heat, thereby reducing primary energy demand.

Electrical Energy (Power Consumption in Systems & Processes)

Reduction through intelligent energy-saving and control technologies as well as demand-based operating modes, e.g., automatic energy-saving circuits to reduce peak loads and operating times.

Compressed Air (Generation & Distribution)

Cost savings achieved by reducing generation losses (optimized compressors/controls) and utilizing compressor waste heat for heat recovery, thereby lowering electricity costs and replacing heating energy.

Process and Cycle Optimization

Machine and Process Optimization as Drivers of Efficiency

Where relevant, we integrate the effects of process and cycle optimizations into the overall analysis—so that savings are not viewed in isolation, but rather as part of a coherent overall concept (system + process). ONI also draws on its experience and consulting expertise in cycle optimization as a component of an energy optimization concept.
