A holistic model for designing and optimising sustainable prefabricated modular buildings

Abstract

Prefabricated Modular Structures are increasingly becoming popular as a strategy that can be used to achieve cost effective and speedy construction. However, there is an absence of detailed engineering research or case studies dealing with the structural performance or building optimisation and integration strategies for this technology. This paper presents a conceptual holistic model that can be used to identify the most optimum structural system in a given scenario. A multi-disciplinary approach will be taken to optimise the building by assessing structural systems, materials, sustainability features, constructability and speed and cost of construction. This paper will discuss types of different optimisation strategies adopted in building designs and how they can be modified to assess a prefabricated modular building and what different variables will dominate as key performance indicators in the search for an optimum solution for a prefabricated modular building.
