Manufacturing sites
For organisations analysing process, utilities and production-linked energy use.
Service — Energy Efficiency
Energy Efficiency Consulting
Nexovia helps organisations make energy consumption measurable, identify inefficiencies, prioritise improvement opportunities, and move energy performance into a structure that can be monitored regularly.
TEP calculator
Calculate your site's annual energy use in TEP.
Enter annual consumption for electricity, natural gas and other energy sources to estimate your approximate total TEP. Results are for preliminary assessment only — not official declarations, audits or regulatory interpretation.
Empty fields are treated as zero. Enter annual consumption amounts.

This tool is for preliminary assessment only. Results do not replace official energy audits, regulatory obligation checks, VAP applications, ISO 50001 certification decisions or official declarations. Final evaluation must consider activity type, use areas, production structure, metering infrastructure and current regulation.
Energy efficiency work is more than a savings list.
The aim is to assess electricity, natural gas, steam, compressed air, cooling, HVAC, lighting and process-related use holistically. Official audit, VAP or certification processes that require authorisation under regulation are scoped per project; where needed we work with authorised partners.
Methodology
Process
A six-step, deliverable-oriented methodology. Each step produces a reportable output.
- 1
Initial assessment
Activity type, energy sources, production structure, metering infrastructure, historical consumption and reporting needs are reviewed.
- 2
Data inventory
Existing data sources for electricity, gas, steam, fuel, compressed air, cooling, HVAC and process equipment are mapped.
- 3
Site review
Use points, main equipment, utilities, meters, panel layout, operating habits and maintenance records are assessed on site.
- 4
Consumption analysis
Energy use is analysed over time and linked to production, capacity, operating hours, seasonality and operational intensity.
- 5
Efficiency opportunities
Short-, medium- and long-term improvements are identified and prioritised by estimated impact, investment, feasibility and operational risk.
- 6
Reporting and monitoring
Outputs are packaged for management. Where appropriate, KPIs, targets and action tracking structures are designed.

Energy performance is managed through regular measurement and sound interpretation.
The value of energy efficiency work is not only one-off savings suggestions. The real value is understanding which activities drive consumption, spotting deviations early, grounding investment decisions in data, and making energy performance regularly reportable.
A strong start for ISO 50001 readiness: data, boundaries and indicator discipline.
Organisations building an energy management system first need clear energy boundaries, significant energy uses, data sources and performance indicators. Nexovia supports ISO 50001 readiness through structured energy data, defined responsibilities and monitoring design.
Energy efficiency is one of the strongest data domains in sustainability reporting.
Energy use is directly linked to carbon emissions, operating cost and resource efficiency. Energy efficiency work creates a reliable data base for ESG, sustainability reporting and corporate environmental performance indicators.
Who is it for?
Food and beverage plants
For sites tracking energy across cooling, steam, hot water, cleaning, process and packaging lines.
Chemical and industrial operators
For high-intensity processes requiring systematic review of consumption, losses and improvements.
Hotels and large campuses
For managing HVAC, hot water, lighting, kitchens, laundry and common-area consumption.
Industrial zones and multi-site groups
For comparing, reporting and identifying shared improvement areas across multiple facilities.
FAQ
Frequently asked questions
Where does an energy efficiency engagement start?
We begin with consumption data, bills, metering layout, main equipment and operating patterns, then clarify where use occurs through field assessment.
Do you deliver official energy audits?
Audit, VAP or certification processes that require authorisation under regulation are scoped per project. Where needed we work with authorised partners.
Do you provide ISO 50001 certification?
Nexovia can support ISO 50001 readiness, data structures, performance indicators and management-system design. Certification body services are a separate process.
How long does the work take?
Duration depends on site size, data quality, field access, equipment diversity and report scope. A clear timeline is agreed after the initial assessment.
Is it only for industrial plants?
No. Hotels, hospitals, campuses, logistics centres, industrial zones and large commercial buildings can all benefit.
Can energy efficiency run alongside sustainability consulting?
Yes. Energy use is a core data domain for sustainability and carbon reporting, so both tracks can be designed together.
