This course deals with further discussions on the development and scientific principles of environmental science relating to the built environment. Apart from the environmental science, this course also provides students with the opportunity to understand and relate the importance of principles, operation concepts and installation of the services commonly provided in habitable buildings. The learning process includes a study of the specific characteristics of each type of service, the safety requirements for both installation and operation and the relationship between services systems and the building envelope and other internal components. The correlation between the design appreciation of the system and environmental control installed in buildings also included.
