Goal setting in sustainable building renovation - Early prototype design and testing of a new decision support tool

Abstract

This paper presents an early prototype of a new value-based decision support tool that can support building owners in setting goals for sustainability in renovation projects. The prototype includes the main functionalities of choosing and weighting criteria. Five users tested the prototype using think-aloud testing. The results showed that providing a pre-defined set of criteria for the goal setting made the users feel locked in their choices, and challenged in weighting criteria using the analytical hierarchy process. The results have informed the further design iterations of the prototype.
