CMA433: ENVIRONMENTAL SCIENCE AND BUILDING SERVICES ENGINEERING

About This Course

This course's integration of environmental science and services engineering offers a structured introduction to both scientific principles and important service features related to the built environment. Students will have the chance to comprehend and research the significance of climatic variables in design in relation to comfort in this course. Thermal environment, heat, air movement, natural ventilation, and humidity are the key subjects that are covered. The development of knowledge and application of the design and installation of the water supply, sanitation, sewage, electrical supply, and solid waste disposal systems that are often provided in habitable structures were addressed in the other half of the course. Studying installation and operating needs as well as the interactions between services systems, the building envelope, and other internal components are all part of the learning process.
