1. Potential of Ventilation Radiators : Performance evaluation by numerical, analytical and experimental means
Sammanfattning : Energy consumption for heating and ventilation of buildings is still in 2011considered far too high, but there are many ways to save energy and construct lowenergy buildings that have not been fully utilised. This doctoral thesis has focused onone of these - low temperature heating systems. LÄS MER
2. Natural Ventilation and Air Infiltration in Large Single‑Zone Buildings : Measurements and Modelling with Reference to Historical Churches
Sammanfattning : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. LÄS MER
3. Ventilation and window opening in schools, Experiments and Analysis
Sammanfattning : The objective of this thesis is to study the application of ventilation in schools buildings. A number of studies of the application of different forms of ventilation are presented. The main part of the thesis focuses on window opening in a classroom. Analytical models for calculation of the air change caused by window airing are proposed. LÄS MER
4. Heat Flow in Building Components, Experiment and Analysis
Sammanfattning : Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. LÄS MER
5. Thermal models of buildings : determination of temperatures, heating and cooling loads : theories, models and computer programs
Sammanfattning : The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. LÄS MER
