Application

Design takeaway

How to apply

When evaluating design options based on multiple sustainability criteria, use a value function to translate subjective preferences for each criterion into a common scale, allowing for a unified assessment.

Project actions

01When defining your project's sustainability goals, consider how you will measure and compare them.
02Explore using value functions to represent user preferences for different design features related to sustainability.

Method & Evidence

AimHow can a generalized value function equation be developed to accurately represent decision-maker preferences for diverse sustainability attributes in a clear and easily applicable manner?

MethodMathematical modelling and application of a proposed generalized value function.

ProcedureThe study developed a new general equation for value functions, which can represent various common preference relationships (linear, convex, concave, S-shaped) by adjusting parameters. This equation was then applied to four sustainability variables relevant to industrial buildings.

ContextIndustrial building design and sustainability assessment.

Variables

IVParameters of the generalized value function equation.

DVDecision-maker preferences for sustainability attributes.

CVSpecific sustainability attributes being evaluated (e.g., energy consumption, material waste).

Strengths & Limitations

Strengths

+Provides a flexible and unified framework for sustainability assessment.
+Addresses the challenge of disparate units in multi-criteria decision-making.

Limitations

It can be difficult to accurately capture true user preferences, and the chosen mathematical model might not perfectly represent complex human decision-making.

Reliability & validity

Reliability would depend on consistent preference elicitation. Validity would be assessed by how well the chosen function accurately reflects stated preferences and leads to decisions aligned with those preferences.

Think critically

How might the choice of a specific value function shape (linear, concave, convex) influence the final design decisions, and what are the ethical implications of such choices?

Design Principles

"Quantify subjective preferences for sustainability attributes using a flexible value function to enable objective multi-criteria decision-making."

In design practice, sustainability often involves balancing competing objectives with disparate units. This research offers a method to translate subjective preferences into a quantifiable framework, aiding in more objective and transparent decision-making for complex projects.

What This Means for Your Design

This study created a math formula that helps designers figure out what's most important to people when making something sustainable, even if the 'important things' are measured differently (like energy saved vs. materials used).

How to use in your project

1.Use the concept of value functions to justify the weighting of different sustainability criteria in your design evaluation.
2.Reference this study when discussing the challenges of multi-criteria decision-making in sustainable design projects.
