A functional definition of sustainability for housing requires meeting present needs without exceeding the planet's annual CO2 absorption capacity, making per-house emissions targets crucial. This sustainability research insight is drawn from a 2010 study published in Figshare. Using Literature review, definition development, quantitative analysis (embodied energy and co2 analysis), case study application., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design projects aiming for sustainability should set clear, measurable annual CO2 emission targets for the entire lifecycle of the building, from construction to operation.

Key Findings
- 01A functional definition of sustainability is 'meets the needs of the present without annual CO2 emissions exceeding what the planet can absorb'.
- 02Energy and CO2 analysis are effective methods for measuring environmental impact.
- 03Global and per-capita CO2 absorption limits can be applied to determine sustainable targets for specific sectors, such as housing.
- 04A sustainable annual per-house emissions target can be identified for New Zealand's housing sector.
Application
Design takeaway
Design projects aiming for sustainability should set clear, measurable annual CO2 emission targets for the entire lifecycle of the building, from construction to operation.
How to apply
When designing a new house or renovating an existing one, calculate the estimated annual CO2 emissions for construction materials, maintenance, and energy use, and strive to meet or exceed a target derived from global per-capita absorption rates.
Project actions
- 01Clearly define what 'sustainability' means for your specific design project.
- 02Use CO2 emissions as a primary metric for evaluating design choices.
- 03Consider the entire lifecycle of your product or system, not just its use phase.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a clear, functional definition of sustainability.
- +Introduces a quantifiable metric (CO2 emissions) for assessing housing sustainability.
- +Applies theoretical definitions to a practical sector (housing).
Limitations
The accuracy of your CO2 calculations will depend on the data you can access for materials and energy consumption, which may vary in availability and detail.
Reliability & validity
The reliability of the findings depends on the accuracy of the CO2 data sources used for materials and energy. Validity is supported by the logical derivation of targets from global limits and their application to a specific sector.
Think critically
If CO2 emissions are the primary metric for sustainability, what other environmental factors might be overlooked, and how could they be integrated into a more holistic sustainability assessment?
Design Principles
"Quantify and minimize the carbon footprint of design solutions across their entire lifecycle."
This research provides a quantifiable framework for assessing the sustainability of housing design. By focusing on CO2 emissions, designers and engineers can move beyond vague notions of 'green building' to concrete, measurable targets that align with global environmental limits.
What This Means for Your Design
To build a sustainable house, focus on how much carbon dioxide it produces each year, including when it's built and when people live in it. This amount should be less than what the Earth can naturally absorb.
How to use in your project
- 1.Reference this study when defining sustainability goals for your design project, particularly if focusing on environmental impact.
- 2.Use the concept of setting measurable targets (like CO2 emissions) as a methodology for your own research and design evaluation.
