MAEN4400 Automation in Building Course description

The main goal of automation systems in buildings is to ensure the right indoor climate for the lowest possible energy consumption. The subject will provide a deep understanding of control principles at different levels in building automation. Furthermore, general and special system solutions that combine heating, cooling, heat pump and ground source heating / cooling will be reviewed in a common integrated solution. Relevant programming languages/softwares will be used to develop simulation models for various regulatory analyzes for "exact regulation" and to use Proportional Integral Derivative (PID) regulation.

None

After completing this course, the student has the following learning outcomes, as defined in knowledge, skills and general competence:

Knowledge The student has

• advanced knowledge of control and control technique
• specialized knowledge of the algorithms for P, PI and PID regulators
• knowledge of the principles of DDC regulators, PLS units
• knowledge of BUS systems and central operating control systems
• specialized knowledge of contracting bodies and actuators.
• in-depth knowledge of various alternative control systems for heating, cooling, ventilation and lighting.
• knowledge of modeling and simulation of ventilation heating and air conditioning systems with regard to control and regulation

Skills The student can

• apply scientific methods to issues in control, regulation and building automation independently
• consider indoor climate, energy use and operating costs related to automation systems integrated in buildings
• Choose the right methods for control and regulation of heating, cooling, ventilation and lighting systems
• calculate the maximum capacity of the contracting bodies and find the curve shape of the characteristics
• calculate and evaluate time constant for various components of control systems

Lectures, exercises and project work.

The following work requirements must be approved or admission to the exam:

• Five individual exercises related to lectures, each on two to three pages.

Part 1 Individual written exam of three hours, which counts 70 percent.

Part 2 Project work in groups of three to five students and which counts 30 percent. Report, implementation, oral and visual presentation in group are considered.

Exam part 1) Exam results can be appealed. Exam part 2) Exam result cannot be appealed.

Both parts of the exam must be graded / E or better in order for students to pass the course.

In the event of a new and postponed individual written examination, oral examination forms may be used. If an oral examination is used for a new and postponed examination, this cannot be appealed.

Exam part 1: Assistive products annexed to the examination paper. Handheld calculator that does not communicate wirelessly. If the calculator has the possibility of storage in the internal memory, the memory must be deleted before the exam. Sampling can be done.

Exam Part 2: All.

Graded scale A-F

Part 1 An internal sensor.

Part 2 Two internal sensors.

External censorship is used regularly.
