| Aim: To give the students a thorough knowledge of the building envelope's significance for keeping a good thermal indoor climate with the least consumption of energy, and an understanding of how the choice of materials and configuration of structures influence the thermal resistance and moisture conditions of the building envelope. The course should enable the students to carry out a hygrothermal specification of the building components that form part of the building envelope, set up and calculate multidimensional or transient heat and moisture balances for building components, spaces and buildings. Furthermore, the course shall give the students an understanding of the specific problems connected with low energy buildings, regarding building technology, indoor climate, and economy. The course will enable the students to design low energy buildings as well as energy renovation of existing buildings. |
Contents: Calculation of energy consumption for heating of spaces and buildings. Computer programs for buildings with multiple spaces (zones) and systems for heating, cooling, and ventilation. Theory of transient and multidimensional heat transport. Computational models for transient thermal analysis of buildings. Analysis of the influence of the building envelope on indoor climate and energy consumption. The dynamic thermal properties of building components. Analysis of thermal bridges. The hygrothermal properties of the building envelope. Advanced moisture transport theory (moisture accumulation, capillary transport, convection). Computational models for transient analysis of moisture conditions of building components.
Aimed at low energy buildings an analysis of the heat balance and thermal indoor climate of the house related to its form, size and design is made. Another topic will be the air tightness of the house and how to obtain it. The influence of fresh-air ventilation on energy consumption and thermal indoor climate is analysed. A special topic will be the design of windows, atria and solar walls. Methods of analysing daylight in buildings are examined. Methods of making and calculating energy renovation of different building types are studied. The composition of the building envelope in dwellings and commercial buildings. Insulation of technical systems at high and low temperatures. Measuring techniques for building physical investigations. |
