Course Purpose and Objectives

Purpose: The course uses the concept of sustainability to frame an understanding of the built environment at the community and individual building level by investigating the interaction between the urban and the natural systems. The purpose of the course is to provide students with insights on the role of technical and non-technical issues (economic, social, ecological, ethical, philosophical, political, psychological, cultural) in shaping architectural, urban and engineering decisions. Furthermore, since the building sector is responsible for a large use of resources, over the past two decades, construction industry has been required to provide buildings that perform to increasingly higher energy performance standards. In order to tackle this challenge, the course aims at offering students the theoretical foundations and practical hand-outs on building performance simulation (BPS) to enable them demonstrating a theoretical building energy performance using computational models, which this course will cover.

Objectives: The course will provide doctoral students with the advanced concepts of sustainability and sustainable built environment development. Additional emphasis is placed on the range of methods (i) to identify and select sustainable solutions to design problems; (ii) to improve existing solutions; and (iii) to stimulate critical reasoning. Students are asked to consider the many aspects of a building project, such as the economic, physical/scientific, social, psychological, historical, ethical, political, cultural and ecological aspects, and how each of these influences
the others.

Learning Outcomes

At the end of the term, student should:

- Possess deep knowledge on the concepts of energy sufficiency and efficiency, sustainability and sustainable built environment development
- Know and understand technical and non-technical issues in shaping architectural and engineering decisions
- Have acquired range of methods to identify and select sustainable solutions to design problems, and to improve existing solution
- Properly adopt computational models to demonstrate theoretical energy performance of buildings 
- know and understand the fundamental principles of BPS, and the theoretical models underlying BPS software
