The purpose of energy consulting is to create different packages of measures to improve energy efficiency, comparing their benefits and costs. This process particularly focusses on the shell of the building, and its ceilings, walls, windows, roof surfaces and heating. Increases in energy costs are taken into account, as is cost-efficiency, initial cost recovery and funding options (in Germany: KfW).

For instance, this includes:

  • Recording the actual condition of the building shell and areas where air escapes
  • The heating and airing habits of the inhabitants
  • The insulation rating of the building shell (U values), and energy and heat balance
  • Heating analysis to identify weak spots, such as pipes, pipe insulation, boilers, pumps, hydraulic balancing, switching off at night and circulation pumps, and describe improvements
  • Analysing hot water supply and fuel consumption
  • Using renewable energies, such as pellet heating or solar power systems
  • Analysing ventilation systems in terms of air hygiene levels and measures to improve energy efficiency
  • Describing measures to optimise energy-related components
  • Creating refurbishment schedules
