Abstract
Since the demands for energy efficient buildings becomes higher and higher it is interesting to look at how we use our energy inside the buildings. Approximately 87% of all energy used inside a house is used for heat, a good way to lower our energy use would therefore be to lower the amount of energy needed for heat. Today there are several different types of heating systems, some regarded more energy efficient than others. In this thesis the option of using underfloor heating systems in single family houses is examined and compared with other systems.
A questionnaire study was conducted in order to see how residents with different heating systems perceive their indoor climate and heating system. Measurements in single family houses using... (More)
Since the demands for energy efficient buildings becomes higher and higher it is interesting to look at how we use our energy inside the buildings. Approximately 87% of all energy used inside a house is used for heat, a good way to lower our energy use would therefore be to lower the amount of energy needed for heat. Today there are several different types of heating systems, some regarded more energy efficient than others. In this thesis the option of using underfloor heating systems in single family houses is examined and compared with other systems.
A questionnaire study was conducted in order to see how residents with different heating systems perceive their indoor climate and heating system. Measurements in single family houses using underfloor heating systems and radiator heating systems was made, in order to compare the these two systems. Simulations were also made to see which system is the most energy efficient and utilizes thermal mass best in theory. Some interesting factors were further investigated such as flooring materials and moisture addition, how well the different systems contained a steady indoor temperature and how much it was influenced by the outdoor climate.
The results of this thesis shows that underfloor heating systems are both more pleasing and more energy efficient than the more traditional radiator system, if installed and used correctly. On the other hand it also shows that it seems to be harder to install and use underfloor heating systems the right way, this leads to variations in energy efficiency and comfort in residences with this system. The knowledge off the builders and the residences should be high in order for this system to be a comfortable choice. (Less)
