Bioenvironmental Control (B-KUL-I0N79A)
Aims
This course covers the fundamentals of bio-environmental control in order to provide comfortable and productive living/working environments for a variety of living organisms, including humans, animals, and plants.
At the end of this course, students will be able to
- Acquire a foundational understanding of bio-environmental control application fields, terminology, and principles of heat and mass transfer;
- Acquire proficiency in heat, energy, and mass balances;
- Develop a broad comprehension of basic modes of heat transfer;
- Demonstrate the ability to use principles of heat transfer to solve thermal analysis problems;
- Understand the significance of ventilation, thermal insulation and moisture barrier design;
- Discuss the objective, challenges and future trends of occupant-centric control (OCC).

Evaluation
Evaluation: Bioenvironmental Control (B-KUL-I2N79a)
Explanation
The exam is divided into two parts:
1) a closed book part evaluating the theory and
2) an open book part evaluating the insights based on an exercise.
Students must first complete the closed book part before beginning the open book exercise.
