Abstract

![CDATA[Design variables are major determinants of cost of a building and the theoretical stance of the relationship between design variables and cost is already established. However, design economics becomes more interesting when dealing with dual currency – cost and carbon. Also, the knowledge of design economics becomes significant for dual currency management as there is a growing concern to reduce embodied carbon economically. Therefore, the aim of the paper is to review the literature on design economics and deduce relationships between Capital Cost (CC) and design variables; and initial Embodied Carbon (EC) and design variables by collecting data of 10 office buildings in the UK. The relationships are explained through descriptive statistics and comparisons are made between CC and initial EC relationships with that of the design variables. Findings reveal building size, height, façade area and no. of basements are correlated with CC and initial EC of the buildings. Also, a fair linear relationship was evident between CC per Gross Internal Floor Area (GIFA) and EC per GIFA of the buildings which gives an indication that it is possible to reduce both CC and initial EC by concentrating on the outline design.]]
