This course will discuss the utilisation of energy in the present day society, taking into account sustainability and environmental aspects. The course will focus on the technologies used to meet a wide spectrum of energy demands needed for cooling, heating, and ventilation in the built environment.
Aim
After the course the student should be able to· describe different sources of primary energy and assess their environmental impact.
· describe the utilisation of energy in the present day society.
· understand and explain the physics that govern an indoor climate, and assess the changes needed to improve the indoor climate in existing buildings.
· perform heating/cooling load calculations for a single family residence.
· design heaters (radiators) and connecting tubing, and select a proper circulation pump.
· design a ventilation system to provide an adequate air flow of a proper temperature and humidity.
· understand and explain the basic fundamentals of conventional refrigeration systems, including components like heat exchangers, compressors, and expansion valves.
· develop and describe a computer model of a conventional cooling system.
· understand and describe different heating systems, and assess their applicability.
· understand and describe the function of passive systems.
· briefly discuss alternative cooling systems.

The course coordinator will be present during the exam. DO NOT HESITATE to ask if you do not understand the questions!
Project Reports
Each student is required to submit a written report for each of the three assignments:· Seminar 1-2 (1 report): Heating demand for a single family residence, 0.5 credits
· Seminar 3-4 (2 reports): Design of heating and ventilation systems, 0.5 credits
· Seminar 5-9 (1 report per group per seminar): Simulation of a refrigeration system, 1 credit
You can download the assignments from this homepage by clicking here.
In order to promote continuous learning, you will get bonus points on the exam if you submit the reports before the deadline expires and receive a passing grade.
Number of reports with a passing grade (submitted before deadline expires) / Bonus for the exam
7 / + 15 % of score on the exam
6 / + 12 % of score on the exam
5 / + 10 % of score on the exam
4 / + 8 % of score on the exam
3 / + 6 % of score on the exam
2 / + 4 % of score on the exam
1 / + 2 % of score on the exam
Example: You have submitted seven reports, all receiving a passing grade (+ 15 % bonus) and have achieved a score of 40 credits on the exam. Your total score on the exam will be: 1.15 x 40 = 46 credits.
NOTE: If you receive the grade "fail" on one of the reports you will need to correct it and submit it again in order to pass the course. You will NOT receive any bonus points for the corrected report!
