Sustainability · 2018

Key Findings

01A consistent model for Life-Cycle Assessment (LCA) is crucial for reliable environmental performance benchmarking.
02Preliminary benchmarks for residential buildings were defined as 5–12 kg CO2/m2.yr for life-cycle global warming and 68–186 MJ/m2.yr for total primary energy.

Application

Design takeaway

How to apply

When designing residential buildings, calculate the estimated life-cycle global warming potential and primary energy consumption per square meter per year, and compare these figures against the established benchmarks to identify areas for improvement.

Project actions

01When conducting a design project, consider using a Life-Cycle Assessment (LCA) approach to evaluate the environmental impact of your design choices.
02Research existing benchmarks for similar products or systems to set realistic and measurable environmental goals for your design.

Method & Evidence

AimTo develop a framework for quantifying life-cycle environmental performance benchmarks for residential buildings and to define preliminary benchmarks for global warming potential and primary energy consumption.

MethodLife-Cycle Assessment (LCA) based framework development and benchmarking.

ProcedureThe study involved developing a standardized framework for Life-Cycle Assessment (LCA) to quantify environmental performance. This framework was then used to establish preliminary benchmarks for global warming potential (kg CO2/m2.yr) and total primary energy consumption (MJ/m2.yr) for residential buildings.

Strengths & Limitations

Strengths

+Provides a structured framework for LCA in building design.
+Establishes concrete, quantifiable benchmarks for key environmental indicators.

Limitations

The availability and accuracy of data for life-cycle assessments can be a significant limitation, and the benchmarks may vary depending on regional factors and specific building typologies.

Reliability & validity

The reliability and validity of the benchmarks are dependent on the standardization of the LCA methodology and the quality of the input data used. The study emphasizes the need for a standardized framework to ensure comparability, suggesting that variations in data sources and assumptions can affect results.

Think critically

How might the diversity in building materials, construction methods, and climate zones influence the applicability and accuracy of these life-cycle environmental benchmarks?
