The assignment emphasizes the use of relevant 6D BIM-based tools to simulate, analyze and evaluate the architectural design to optimize the energy and environmental performance of the design. We are required to analyze and evaluate the current design scheme, to assess its performance and to ultimately develop a proposal of an energy and efficient building thus reducing the climatic impact on the economy, human living, health and safety as well as its surrounding environment throughout its whole building lifecycle. Consequently, we are expected to develop their design by considering important sustainable design aspects such as site location, orientation, sun path, form and spatial arrangement and building envelope/facade strategies.
