Application

Design takeaway

Integrate green building principles and certifications into design projects to achieve measurable reductions in environmental impact, paying close attention to operational factors influenced by user behavior.

How to apply

When designing new buildings or renovating existing ones, research and apply relevant green building codes and certification systems. Conduct life cycle assessments to quantify potential environmental benefits and identify areas for improvement, particularly focusing on operational energy and transportation.

Project actions

  • 01When designing a product or system, consider its entire life cycle from raw materials to disposal.
  • 02Research and incorporate relevant environmental standards or certifications into your design process.
  • 03Use tools like Life Cycle Assessment (LCA) to measure and compare the environmental impact of different design choices.

Method & Evidence

AimTo assess the potential life-cycle environmental impact reduction offered by different green building code and certification systems.
MethodLife Cycle Assessment (LCA)
ProcedureA whole-building life cycle assessment was conducted on a prototype building model, comparing baseline performance against models compliant with three different green building codes (LEED, ASHRAE 189.1, and IgCC). Impact assessment was performed using TRACI 2.0.
ContextBuilding design and construction

Variables

IVAdherence to green building codes and certification systems (LEED, ASHRAE 189.1, IgCC) vs. baseline building.
DVLife-cycle environmental impacts (e.g., greenhouse gas emissions, primary energy consumption, water consumption, acidification, human health-respiratory impacts, ozone layer depletion, land use).
CVPrototype building model specification, Life Cycle Assessment database, Impact assessment methodology (TRACI 2.0).

Strengths & Limitations

Strengths

  • +Utilizes a robust Life Cycle Assessment (LCA) methodology.
  • +Compares multiple established green building certification systems.
  • +Includes sensitivity analysis to assess the robustness of findings.

Limitations

The study's findings are based on a specific building model and may not be universally applicable. The influence of user behavior introduces variability in real-world outcomes.

Reliability & validity

The study's reliability is supported by the use of established assessment tools (NIST database, TRACI 2.0) and a sensitivity analysis. Validity is enhanced by comparing multiple certification systems and a prototype model, though it is limited by the generalized nature of the prototype and the inherent complexities of real-world building performance.

Think critically

While green building codes show promise, their effectiveness is influenced by user behavior during the operational phase. How can designers create systems that not only meet code requirements but also actively encourage or enforce environmentally responsible user actions?

05
