Sustainability Key Performance Indicators' (KPIs) Assessment and Visualization aimed at Architects in (Early) Renovation Design Processes

Aliakbar Kamari, Stina Rask Jensen, Steffen Petersen, Poul Henning Kirkegaard


Proper data visualization can help architects to deal with design complexity by facilitating a better understanding of the design performances/outcomes, and thereby contribute to making informed decisions. Based on this underlying hypothesis, this article aims to find out: what are the requirements of an effective visualization technique aimed at architects to visualize the outcome of simulation and assessment of renovation design options for multiple sustainability themes or Key Performance Indicators (KPIs)?
The article adopts a bottom-up approach, beginning by a) exploring and assessing multiple KPIs for renovation and b) surveying existing visualization techniques to illustrate the KPIs evaluation outcome in the early design process, through conducting a focus group workshop with eight practicing architects in Denmark.

It is concluded that architects are always looking for a strong narrative when developing design options to address the sustainability KPIs in their practices, and the narrative is different from project to project. In this light, effective visualization techniques should provide a good overview of the problem in question. At the same time data visualization should be functional, insightfulness and enlightening, in order for the architects to fully grasp and accept the evidence it depicts as useful inputs in the design process.
