Life Cycle Costs and Energy Economy of BuildingsLaajuus (15 ECTS)

Objective

- Students can explain the impact of different factors to the energy use of a building. They understand the principles of local solar energy production and use.
- Students can produce the energy efficiency documentation required in the building permit process.
- Students can use dynamic simulation tools to calculate the indoor environment, energy use and cooling load of a building. They master measures to prevent overheating during the summer.
- Students are able to make life cycle calculation to support decision making and assess the environmental impact during the life cycle of a building. They can explain the role of use and maintenance on the energy economy of a building.
- Students can explain the principles and modes of heat transfer and apply them in heat transfer calculations of structures heaters. They can explain how moisture transfers in structures and soil.
- Students can explain the principles of sound and apply them in noise calculations of HVAC systems.
