Course Purpose and Objectives

Buildings consume large amounts of resources in both their construction and operation. Systems for regulating thermal comfort in buildings represent the greatest opportunity for enhancing building energy performance. In addition, thermal comfort represents the top two sources of building occupant complaints while a number of studies have indicated that perceived thermal comfort and established “objective” comfort criteria do not always align. Over the past two decades, construction industry teams have been required to provide buildings that perform to increasingly higher energy performance standards. In the design phase, architects and engineers are able to demonstrate a theoretical energy performance using computer models, which this course will cover.

The objective of the course is to provide students with concepts, methodologies, and the latest results coming from a variety of interconnected disciplines, which help understanding the energy behavior of buildings and settlements.

Learning Outcomes

To achieve the course purpose and objective, the course will include an overview on general principles and concepts together with practical experience on the use of building performance simulation for investigating the theoretical energy performance of buildings. The course is structured in two main parts:

 

1) Sustainability and the Sustainable Built Environment

By the end of the course, students will:

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 solutions

 

2) Building Performance Simulation

By the end of the course, students will:

Properly adopt computational models to demonstrate theoretical energy performance of buildings

Know and understand the fundamental principles of BPS

Know and be able to apply the theoretical models underlying BPS software

Be capable of using one of the building performance simulation tools

Prerequisites

None

Background Requirements

No special background, expertise or skills are required.

Knowledge of building components, building technical systems, and numerical methods is an advantage

Assessment

Students will be given to read at least one book chapter, a scientific publication or a handout for each lecture (i.e. once per week). A discussion will be administered during the classwork on the material studied. Furthermore, an assignment will be given at the beginning of the course, that needs to be handed in to the teacher within the end of the course. The assignment will count for 40% and the final exam will count for 60% of the course grade.
