Sensitivity analysis evaluating basic building geometry's effect on energy use

The paper presents a methodology to evaluate building form to in order to compare energy consumption of geometric variations and material considerations through two types of sensitivity analyses. First, a review of related studies discussing energy and form are discussed, second the geometric methodology for vertical and horizontal proportion is described, and finally the linear screening local sensitivity index and a Morris global sensitivity results are reviewed. Findings compare geometric and material sensitivity, as well as the two different types of sensitivity analyses. Results indicate that both the vertical and horizontal geometric proportion is equally as sensitive as certain material aspects related to building energy use. Outcomes provide building designers clarity on the formal variations in the early design phase informing design decision-making.
