Short answer

Designers must adopt a holistic, life-cycle approach to residential design, with a strong emphasis on minimizing energy and water consumption during the use phase and selecting low-impact materials.

Field: Sustainability
Source: Building and Environment (2018)
Method: Life Cycle Assessment (LCA)
Sample: 24 dwelling archetypes
Evidence: Strong effect

The average European resident contributes 2.62 tonnes of CO2 equivalent annually to greenhouse gas emissions through their housing, with the use phase (energy and water consumption) being the most significant contributor. This sustainability research insight is drawn from a 2018 study published in Building and Environment. Using Life cycle assessment (lca) with 24 dwelling archetypes, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must adopt a holistic, life-cycle approach to residential design, with a strong emphasis on minimizing energy and water consumption during the use phase and selecting low-impact materials.

Key Findings

01Average life cycle greenhouse gas emissions related to housing per person per year are 2.62 t CO2eq.
02Average life cycle greenhouse gas emissions related to a representative dwelling per year are 6.36 t CO2eq.
03The use phase (energy and water consumption) is the most impactful phase, followed by material production and maintenance.
04Single-family houses contribute the largest share of housing impacts.
05Impacts vary significantly by climate zone, primarily due to space heating demands.

Application

Design takeaway

Designers must adopt a holistic, life-cycle approach to residential design, with a strong emphasis on minimizing energy and water consumption during the use phase and selecting low-impact materials.

How to apply

When designing new residential buildings or renovating existing ones, use these figures as a benchmark to assess the potential environmental impact of design choices, particularly concerning energy systems and material specifications.

Project actions

01When researching environmental impacts, consider the entire life of a product or building, not just its creation.
02Use established methods like Life Cycle Assessment (LCA) to quantify environmental performance.
03Compare your design's impact against established benchmarks or averages.

Method & Evidence

AimWhat is the average annual environmental impact per person and per dwelling across the European housing stock, considering the entire life cycle?

MethodLife Cycle Assessment (LCA)

ProcedureA full Life Cycle Assessment was conducted on 24 statistically derived dwelling archetypes representative of the 2010 EU housing stock. The system boundaries encompassed production, construction, use (energy and water), maintenance, replacement, and end-of-life phases. Environmental impacts were calculated using the ILCD method, and results were aggregated to determine EU-wide averages per person, per dwelling, and per square meter.

Strengths & Limitations

Strengths

+Comprehensive life cycle approach.
+Statistically representative archetypes of the EU housing stock.

Limitations

The data is from 2010, so newer, more energy-efficient technologies might not be fully represented. The archetypes are generalized, so individual homes can vary greatly.

Reliability & validity

The study's reliability is supported by the use of a standardized LCA methodology (ILCD) and statistically derived archetypes. Validity is enhanced by the comprehensive system boundaries covering the entire life cycle.

Think critically

How might the increasing adoption of renewable energy sources and smart home technologies alter these life-cycle impact figures in the coming years?

Design Principles

"Minimize life-cycle environmental impact by optimizing the use phase and material selection in residential design."

Understanding the life-cycle environmental impact of housing is crucial for developing effective sustainability strategies. This data provides a quantifiable baseline for assessing the effectiveness of eco-innovations and setting realistic reduction targets in the built environment sector.

What This Means for Your Design

Living in a house in Europe creates about 2.6 tonnes of pollution (like CO2) every year for each person. Most of this comes from using electricity and water, and heating the house. Bigger houses and houses in colder places cause more pollution.

How to use in your project

1.Cite this study when discussing the environmental impact of housing or energy consumption in your design project.
2.Use the reported CO2eq figures as a baseline to compare your design's potential environmental performance against.
