Energy efficient HVAC systems. Renewable energy in buildings. On site energy generation systems. District cooling and heating systems. Principles of building management systems.
To provide the students with
(1) the basic fundamentals required for the analysis and design of heating, ventilating and air conditioning systems for domestic, commercial, and industrial spaces,
(2) To introduce the students to the utilization of computers for the analysis and design of heating, ventilating and air conditioning systems.

Computers are employed in this course as an instructional tool. Students are required to integrate self generated programs with commercially available academic and industrial software packages for the purpose of analyzing and designing heating, ventilating, and air conditioning systems. The course will introduce students to the Software HCB by Peter S. Curtis (http://www.hcbcentral.com/hcb/hcb.htm ) and the US Department of Energy Energy-Quest™. For customized codes, any programming language is acceptable, however, MatlabTM is preferred.
Sample of Laboratory/Design Projects:
- Cooling and heating load estimation for a residential building to be in designated places around the world.
- The second project will consist of providing correctly sized heating, ventilation and air conditioning loads and size the equipment for a commercial building. Use of ASHRAE standards 55-2010, 62.1-2010, and 90.1-2010 should be demonstrated in the final project.
- 3-4 homework will be assigned based on assigned textbook and Professor’s problems. Two design projects will be assigned during the semester.
- Two 90 minutes long mid-term exams with score of 100 points each will be given during the semester along with one final examination.
- 2 quizzes, 30-45 minutes, long, will be given during the Fall semester.
- The final grade will be calculated using the following weight factors:
- Mid Term Exams – 40 %
- Final Exam – 20%
- Design Projects – 20%
- Quizzes – 10%
- Homework - 10%
- Final Grade will be determined based on the following score
- A - 90% and above
- B – 78% - 89%
- C – 62% - 77%
- Building sciences, energy consumption by buildings.
