Ecological Efficiency of Heat Generators 

Review of heating systems over their entire product life cycle including a dynamic life cycle assessment and ecological efficiency analysis 

Objective

The aim of the project is to assess the environmental impact and economic efficiency of heating systems using pellets, heat pumps and gas heating systems, also in combination with solar thermal energy, along their entire product life cycle.

Tasks

The dynamic analysis of the results from the life cycle assessment and economic efficiency evaluation should allow for the modelling and forecasting of the effects of various different heating systems over their life cycle. Climate-relevant and environmental factors are included in the system review and assessment. This allows us to identify the heating systems with the smallest environmental and climate impact, as well as the lowest costs. The research tasks include:

  • Building-specific design of heating systems
  • Economic assessment of various heating systems
  • Compilation of mass and energy balances
  • Compilation of life cycle assessments
  • Sensitivity analyses with varying parameters
  • Determining the ecological efficiency of heat generators
  • Development of dynamic life cycle assessments

Status Quo

Over 50% of the final energy consumption in Germany is used for heat generation, particularly heating and hot water preparation in buildings. Emissions from heating systems also make up a significant proportion of anthropogenic environmental pollution. Until now, the focus when buying heaters has been primarily factors such as acquisition costs, current fuel prices and price ratios, as well as individual factors such as efficiency or fine dust emissions. When buying heaters or switching heating systems in the future, one will have to take into account information on the climate and environmental impact over the entire service life of heating systems.

Advantages

  • Dynamic life cycle assessments and ecological efficiency analyses enable:
  • the assessment of the climate-relevant and environmental impact of heating systems
  • the modelling of effects over the entire service life of heating systems
  • the correlation of environmental impact and heating costs, and the determination of excellent heat generation systems
  • the comparison of renewable-energy and fossil-fuel heating systems
  • the illustration of best practice examples for sustainable heating systems
  • the minimization of the climate and environmental impact of the heat supply

Project Data and Partners

The “Life Cycle Assessment and Economic Analysis of Heat Supply Technologies for Buildings” project is implemented by the Professorship of Regenerative Energy Systems at the Technical University of Munich.

Project Duration:

February 2020 – January 2023
