Abstract

Decisions made in the early design stages critically determine a building’s life cycle environmental impact and cost. These decisions are characterized by uncertainty, resulting from downstream decisions that have not yet been made. This paper evaluates the effectiveness of three visualization methods in helping professionals make sustainable building design decisions under uncertainty. A charrette involving 63 architects, engineers, and real estate developers was conducted to measure the effect of a scatterplot, histogram, and tornado diagram on design efficiency and solution quality. Participants were tasked with minimizing life cycle environmental impact and life cycle cost of a commercial office building. Each intervention achieved higher-performing designs than when no feedback was provided, and feedback presented in the form of a scatterplot achieved the best results. The research demonstrates the importance of providing designers with quantitative performance feedback to support sustainable building design decision-making and that the quantity and representation of the data should be carefully considered.
