New technologies are being developed by some companies around the world. These companies develop homogeneous space heating for the building and therefore, avoid using the typical water radiators. This is a new technology that could be interesting for research and develop ed for the near futures application with a high possibility for expansion in the markets in a few years. The reason for this is clear. The best conditions for thermal comfort is when all the room surfaces and the indoor air have the same temperature of around 20-22°C. For example, when the outdoor temperature is around 1 or 2 ºC, the temperature of the glass decreases to around 17 ºC. The glass facade becomes significantly colder than any other surfaces or the temperature in the room. Therefore, the radiant heat exchange to the cold window is much larger than towards the room, so the operative temperature deteriorates significantly and consequent ly causes thermal discomfort and is a good reason for the installation of electric heated windows. The project is based in the new building in the Sandvik Coromant that is going to be built during this summer 2013 in Sandviken(Sweden). Specialglas is a Swedish company that provides the electric heated windows that will be installed in a big surface area of 57 . This building is energetically analyzed and simulated with the IDA, building simulation program. Hand calculations are also made for demonstrating these results obtained. Furthermore, the positive results obtained in the thermal comfort aspects are given in this project; as for instance the improvement in the thermal comfort index near the window, where the “ predicted percentage of dissatisfied ” (PPD) for the occupant situated one meter far for the window, varies from 16% with conventional windows to be around 12 %, only when the electric heated windows are working at the minimum supply power. The energy that is needed to maintain the same level of the working electric heated windows is difficult to obtain. This is because there are a lot of uncontrollable factors. Even though there is estimated that the energy demand will increase with 15% of the total energy demand.application/pdfengVentanas calentadas con electricidadElectric heated windowsinfo:eu-repo/semantics/studentThesisinfo:eu-repo/semantics/openAccess
