21. Natural Convection Heat Transfer in a Horizontal Thermal Insulation Layer Underlying an Air Layer
Abstract : In the thesis a study is made of the influence of natural convection on heat transfer in a composite system comprising a porous material heated from below and an air space situated above this. The measuring apparatus, a Wind Box which has been designed and developed at the Department of Building Physics is described. READ MORE

22. Evaluating building envelopes for energy efficient buildings : Energy- and moisture performance considering future climate change
Abstract : Buildings account for a signifi cant proportion of the energy use thatgenerates greenhouse gases and consequently drives the ongoing climatechange. As the population of the world increases, the need for buildingsincreases, while the energy use needs to decrease. READ MORE

23. Development of a non-destructive testing method for thermal assessment of a district heating network
Abstract : This thesis presents the development of a non-destructive testing (NDT)method for thermal assessment of pre-insulated district heating (DH) pipes with high accuracy, in which the development process from literature review to its present stage is presented and discussed. Pre-insulated DH pipes have been in use for more than 40 years. READ MORE

24. Determination of the thermal conductivity of the insulation in district heating mains : Field measurements
Abstract : This thesis concerns the development of a measurement method for determination in the field of the thermal conductivity of the insulation in buried district heating mains. The thermal conductivity of the insulation is calculated from the measured value of the radial heat flow through the heating main, the measured temperature difference across the insulation, and the dimensions of the heating main.
