Implementation of microencapsulated PCM as concrete addition in prefabricated radiant-walls solutions. A feasibility study of the combination of Micronal & In-Term Klimavaeg, as an in-space thermal energy storage solution for heating applications

Traditional heating and cooling solutions are currently being replaced with new low-temperature technologies, which reduce energy consumptions and reach a more sustainable approach.The current status of the European construction sector and the European energetic plans Europe 2020 and Europe 2050, presenta potentialmarket expansion in the energetic renovation area. As one of the main emitter technologies, the implementation of radiant heating and cooling in constructive elements such as radian!floors, walls and ceilings has experienced a considerable growth during the last decade in Europe, and is highlighted as one of the most efficient heating and cooling solutions available. The comparison of the principal radian!wall panel manufacturers in the European market shows a lack of products with high TES capacity, which opens a field for innovative products reaching greater thermal mass values. The implementation of PCM in construction products (laten!heat) allows the improvement of the TES capacity of these materials without increasing the volume of the element or rising the element temperatures. The present study analyses the feasibility of integrating BASF Micronal (microencapsulated PCM) in the concrete layer of a prefabricated radian!wall element (ln-therrn Klimavceg). This research is focused on the increase of the TES capacity of the element, in order to reduce heating costs by balancing the energy demand on electricity peak hours (Smart Metering). The results of the present research showed that the addition of Micronal in the concrete layer of ln-therm Klimavceg is technically feasible (mechanically and thermally), doubling the element TES capacity. Despite that the combination with smart metering solutions reaches small costs reductions, the results reached during the present study opens a vast range of applications for the thermalimprovement reached on ln-therm Klimavceg.Máster europeo en Ingeniería de la Construcció

Systems for Sustainable Energy Supply for Small Villages

ABSTRACT. The main aim of this report is to identify the different sustainable sources and systems of energy and their technological principle which are under substantial development replacing the conventional or traditional sources of energy. It is also the objective of this study to identify the advantages and disadvantages of each system of energy in their actual application now and in the future. In addition, the report discusses the different Energy Systems and Efficient Energy Management systems, which are currently in use. Moreover, the report addresses the environmental, social and economic aspects sustainable energy in the context of buildings and small villages.Máster europeo en Ingeniería de la Construcció

Development of Sustainable Energy Supply Solutions for Fons, Denmark : Analyses and proposal for integrated heat and electricity supply in a 71 household community

ABSTRACT. This research work aims at recommending a suitable renewable energy supply system for the inhabitants of a small village in Denmark called Fons. It envolves studying of the different alternatives of renewable energy supply technologies which has been theoretically developed in the previous group project work entitled "System for Sustainable Energy Sypply for a Small Village" for the production of heat and electricity, being the heat a priority because that is the inhabitant's desire. It is the hope of the research team that implementation of the output of this research work will liberalize the people of Fons community from using unsustainable, non-renewable energy sources such as fossil fuel as their main source of energy.Máster europeo en Ingeniería de la Construcció
