Conventionally, designs are simulated by varying the opening percentages, shading devices and material specifications for validation only in the later stages of design which deal with the skin of the building and involve upfront investment. Instead, options of the design concept ought to be compared with each other to minimise solar gain in the early conceptual stage when maximum amount of saving can be achieved by just varying the shape without additional investment. For example, a simple cuboid can be arranged in 360 orientations and infinite number of aspect ratio (length:width:height). If the optimised orientation and aspect ratio are selected in the conceptual stage, solar gain can be reduced upto 30% just by virtue of a smarter shape.The objective of the course is to optimise the shape of buildings within the framework of design concepts for minimum solar gain through parametric comparative analysis using Grasshopper and Ecotect. The course shall have four technical parts – i) connecting Grasshopper and Ecotect for automated parametric simulations, ii) parametric representation of design concepts for optimisation, iii) techniques of linear optimisation of single variable and evolutionary optimisation (genetic algorithm) of multiple variables, and iv) exporting the simulation data to Excel for analysis. To explore these parts, the course shall have three major exercises among other minor exercises – i) Check the validity of the thumb-rule prescription of aligning the longer faces of the wall to North and South, ii) optimise a cuboid for minimum solar gain throughout the year, and iii) scripting various geometric systems (L,C,U-shapes, courtyard, boolean types, multiple wings etc) for optimisation.
