This paper describes the design and the energy performance of a zero consumption building. The Passivhaus Standard is taken as a reference for the design of the building. The German Passivhaus standard is usually known for its low energy requirements that need low demand for heating and cooling. In addition, important issues to consider in the design stage of a building are analyzed in order to ensure efficient energy consumption. Once the final design of the building is defined, it is necessary to check that it is adequate. To achieve the objectives, the building energy simulation is used, the method that provides more realistic results. The simulation is performed with the software EnergyPlus (EP). Finally, to check the profitability of the building designed, a building whose envelopes and facilities solely satisfy the criteria established by the Spanish Building Technical Code (CTE) is analyzed and simulated. The results demonstrate that the passive building is profitable in few years. [ABSTRACT FROM AUTHOR]

The main developments in offshore wind power are focused on wind turbines with foundations on seabed. However, there exist important limitations for installing these structures exist in places with high depth within short distance from the coast. This means that the progress of offshore wind energy around the world is tied to the development of safety and low cost floating platforms for renewable energy offshore devices . Therefore, the first aim of this paper is to know which alternatives exist for a floating offshore wind farm establishment and design parameters are independent or dependent of platform configuration. In order to evaluate each alternative, the request inversion for each configuration has been analysed. From this point of view, the conclusion is that a string configuration for the electrical network is better than a star configuration. With regard to maintenance, it would be better to have a proper vessel only if the number of trips is more than three. [ABSTRACT FROM AUTHOR]
