Orientation of multi-unit housing

01 Jan 2014

Studio Pacific’s summer scholar for 2013/2014 was Elzine Braasch. Elzine’s study of modular terrace houses in Auckland sought to find optimal building orientation, façade design and layout to inform the master plan for a housing development.

Two terrace house modules of different sizes within a large multi-unit development were analysed. EnergyPlus models were based on the preliminary design concepts with sufficient zones that the thermal performance of each functional space within the terrace house could be studied.

Of the two modules, the smaller terrace house had the greatest difference in performance between best and worst orientations. Further investigation determined that the major determinant of this difference was neither size, nor plan layout of the buildings, but the larger imbalance in window to wall ratios of the two exposed facades.
