Kort beskrivelse av oppgaven:
In the future buildings the materials may be tailor-made for achieving miscellaneous functions based on their respective properties. Within this work task there will be a focus on the building envelope, especially related to the climate screen. Examples of these state-of-the-art, new and emerging materials technologies may be vacuum insulation panels (VIP), aerogels, phase change materials (PCM), nano insulation materials (NIM), smart windows, electrochromic materials, photochromic materials, thermochromic materials, light-weight glass materials, superlow-emissivity materials, building integrated photovoltaics (BIPV), various solar cell materials and technologies. Multifunctional building envelopes represent another interesting aspect. These materials technologies must also satisfy the building physical aspects of their buildings. Both experimental and theoretical studies may be carried out, also including numerical analysis and modelling. Furthermore, the students will be challenged to write their report as a scientific journal article, which thus will be submitted to an international journal for publication if the quality is satisfactorily high. Among others, one possibility will be to write so-called state-of-the-art and future research articles. Specific experimental work tasks in the laboratory may also be possible, e.g. along a PhD student in the field. Specific details about this work task will be given upon request and in discussion groups with dedicated scientific personnel at the departmentBifacial solar cell panels are mounted on a flat roof on NTNU Gløshaugen campus (Sentralbygg 1). The panels are mounted on four racks which each holds two panels. Furthermore, the panels may be turned and tilted in the desired directions and inclinations either manually or automatically (e.g. tracking the sun). Various roofing materials with different solar radiation reflection abilities will be placed under the bifacial solar cell panels, including reference roofing materials, specifically developed reflecting roofing materials, other highly reflecting materials, and snow and frost layers during winter. Weather data (e.g. solar radiation) will also be measured. Moreover, comparisons with field studies of bifacial solar cell panels mounted on the flat roof of an Isola factory building in Porsgrunn may also be possible. In addition, these roofing materials will also be studied in the laboratory by e.g. measuring their total, direct and diffuse reflectance values in the whole solar wavelength spectrum. The field and laboratory studies will also be compared with theoretical modelling work. The students may work in teams with their own defined separate work tasks they are the main responsible persons for or in more individual work tasks. Specific and tailor-made work tasks will be discussed and assigned in meetings between the students and the supervisors.
