Energy audits and expert reports

Energy audits for businesses and technical expert reports on systems, energy consumption and heating costs.

Two approaches

Audit or expert report?

Both start with consumption data and a site visit. They differ in their purpose.

Energy audit

Where is your business losing energy, and which improvements are worthwhile?

  • Consumption data, system information and a site inspection are brought together
  • Energy use is examined systematically
  • Measures are assessed and prioritised

Expert report

A specific technical question needs a reliable answer.

  • Energy and heating costs, bills and contracts
  • Energy performance assessment of technical systems
  • A technically substantiated answer to the agreed question

Energy audit process

From consumption to action

  1. 01

    Collect the basic information

    Consumption data, sites, operating hours and information on technical systems provide the starting point.

  2. 02

    Investigate on site

    Together we agree which areas to examine and supplement the data with measurements where necessary.

  3. 03

    Assess measures

    The findings are documented, and improvements are assessed technically and economically and prioritised.

Measuring equipment

When consumption data alone is not enough

  • Infrared thermography cameraHigh resolution, with a cooled sensor
  • Energy consumption metersWith load profile recording
  • VideoscopyCamera-based diagnosis of pipe systems
  • Clamp metersFor assessing PV yields
  • Infrared thermometersFor quick temperature measurements

Topics

What our expert reports cover

  • Energy supply contracts
  • Energy bills
  • Heating
  • Ventilation
  • Plumbing
  • Electrical systems
  • CHP units
  • Heat pumps
  • Solar systems
  • Wind turbines
  • Hydropower plants
  • Biomass plants
How is the initial assessment carried out?

We agree the relevant sites and areas of investigation with you. Energy bills, existing measurement data, system documentation and operating hours provide the basis for analysis and the site inspection.

What questions can an expert report address?

Examples include the energy performance assessment of a technical system or an examination of energy and heating costs. The objective, available documentation and necessary investigations are agreed before work begins.

What will you receive?

The findings and their basis are documented transparently. An audit assesses opportunities for improvement; an expert report answers the agreed question with technical justification.
