01

Key Findings

  • 01The gas boiler system exhibits a higher overall load, primarily driven by the depletion of abiotic fossil fuels.
  • 02Geothermal heat pump systems demonstrate a lower impact on fossil fuel depletion compared to gas boiler systems.
02

Application

Design takeaway

When designing building services, opt for heating solutions that leverage renewable energy sources to minimize the depletion of non-renewable resources.

How to apply

When specifying heating systems for new constructions or renovations, conduct an LCA to compare the environmental impact of various options, with a focus on primary energy resource depletion.

Project actions

  • 01When researching heating systems, look for data on their full environmental impact, not just running costs.
  • 02Consider using LCA tools to compare the sustainability of different design choices for your project.

Method & Evidence

AimTo compare the primary energy resources and environmental impacts of geothermal heat pump, gas boiler, and hybrid absorption heat pump systems using a Life Cycle Assessment.
MethodLife Cycle Assessment (LCA)
ProcedureCradle-to-gate assessments were conducted for renewable, conventional, and mixed energy systems. System scenarios were compared based on loads and energy resources. Impact categories were normalized and weighted using CML, ReCiPe, and EF 3.0 methods to develop models for environmental reliability and decision support.
ContextResidential and commercial building heating systems

Variables

IVType of heating system (geothermal heat pump, gas boiler, absorption heat pump)
DVPrimary energy resource depletion, acidification, emissions, material resource usage
CVSystem load, energy resource type (renewable/non-renewable)

Strengths & Limitations

Strengths

  • +Comprehensive Life Cycle Assessment methodology.
  • +Comparison of multiple impact categories and normalization/weighting methods.

Limitations

The availability and cost of geothermal energy infrastructure can be a significant practical limitation.

Reliability & validity

The use of established LCA methodologies (CML, ReCiPe, EF 3.0) enhances the reliability and validity of the findings. However, the specific data inputs and assumptions within the LCA can influence the results.

Think critically

How might the 'cradle-to-gate' assessment differ from a 'cradle-to-grave' assessment for these heating systems, and what additional environmental impacts might be revealed?

Design Principles

"Minimize reliance on finite resources by prioritizing renewable energy integration in system design."

Understanding the full environmental footprint of heating systems, from resource extraction to operation, is crucial for sustainable building design and energy policy. This research provides quantitative data to inform choices that minimize long-term environmental burdens.

06

What This Means for Your Design

Using geothermal energy for heating is much better for the planet than using gas because it uses up way less of the Earth's fossil fuels.

Paragraph starter

Life Cycle Assessment studies, such as the one by Mannheim et al. (2023), highlight that heating systems relying solely on renewable geothermal energy exhibit significantly lower primary energy resource depletion compared to conventional gas boiler systems. This underscores the importance of prioritizing renewable energy integration in building design to mitigate the long-term environmental consequences of fossil fuel consumption.
