Summary: Purpose and Scope: The realization of this thesis aims to investigate a new methodology or constructive system that reduces siniestralídad labor construccíón of invemaderos type Gothic or multitúnel at the same time to improve and facilitate the working conditions of operaríos. Methodology: Develops different alternatives to build the greenhouse insurance from a working hypothesis: build most of the greenhouse to the ground and then raise it to its final position by some mechanism, so that occupational risks arising from work at height is minimizasen maximum. To implement this new procedure, it has been necessary to design new parts and mechanisms, which have been analyzed to verify their resistance to the efforts to which they will be subjected. Results: The results of this thesis come to propose precisely these measures to avoid risks of working at height, as the new procedure constructive expected to assemble at ground level to a great extent. It is important to mention that for the development of this investigation has been taken into account that the proposed amendments will be addressed at a cost balanced in a way that is economically viable at the time of build, thus allowing its commercial introduction.

Summary: The work presented here focuses on the study of the environmental conditions inside the traditional underground cellars of a wine region typically: Ribera del Duero Soriana. The objective of this thesis is to assess the advantages these constructions presented for the upbringing and storage of wine, with a view to its possible reuse. Given that at present many of these wineries are abandoned and endangered by the lack of use, we believe it is necessary to address not only possible reuse valuing cultural and aesthetic aspects of these buildings, but with a broader approach taking into account environmental and energy aspects. It compares the results of the monitoring of environmental conditions in the interior of several traditional underground cellars and commercial semi-aéreas. These results are, in turn, contrasted with the values of temperature and relative humidity for optimal parenting wine, in order to determine what type of wineries provide more favorable conditions. This comparison shows that the traditional underground cellars have better thermal performance that holds commercial analyzed. In this thesis, likewise, will employ two additional tools: the simulation energy buildings and infrared thermography. The energy simulation is carried out through the use of software EnergyPlus, which lets us know the temperatures that occur in the interior of underground cellars and air, once they know the characteristics of the same. We can generalize the results of applying the technique to other types of warehouses and other locations. The thermography is a technique that allows quick recognition of the thermal conditions inside the warehouses at any given time, thus allowing comparisons snapshots of a large number of buildings, however, requires further processing of the images in order to to avoid misinterpretation of the same. Once collected information from the monitoring, simulation and thermography, offered the findings regarding the environmental benefits of reusing the traditional underground cellars, stressing that not all of these wineries have the same temperature. The depth and soil type are two important parameters relevant temperature and relative humidity that occurs in the cave, while other factors such as the surface of the cave determine that the winery can be reused for commercial purposes.

Summary: This paper deals with the building of raw land, addressing more specifically with regard to their regulation, since the motivation of the development of a standard for the Spanish case. As a starting point is a version of the state of the art of building with raw land, and the general system of building regulations in Spain, which would value the position in the same building with earth, so it probes the need for a development policy itself. Among a list of over a hundred documents relating to the regulation of building with earth at the international level are selected finally 46 references coming from countries as diverse as Brazil, the United States, India, Kenya, New Zealand, Peru, Zimbabwe, Australia and Spain, as well as international entities African, Latin American or United Nations. These documents are analyzed in detail. They seek land use raw mainly in the form of mud, compressed earth block and tapial for use in building walls in buildings with simple burdens of average height and limited. The documents are very varied types, comprehensive, content and structure quite different. Recorren from items such as a very limited test or the requirements of the piece of mud, very broad themes defining all stages in the process of design and construction with raw land. In this thesis is a comparative analysis of content related to the characterization of the material. We intend to work, providing a basis to guide the preparation of rules of raw land for Spain.

Summary: The research project seeks to produce boards from common reed (Arundo Donax L.), similar to the wooden boards agglomerate advantages, which gives us the cane as common lignocellulosic material, as well as its high tensile strength of its fibers, as well as solve the ecological problem that originates cane common in Vega del Segura. The results further highlight is the collection of boards as a behavior with respect to moisture significantly higher than those found in the market of similar characteristics as the DM or own boards of agglomerate of wood using the same formulations of urea formaldehyde resin that used to latter in the industry of particle boards

Among a list of a hundred other documents relating to the regulation of building with earth at the international level are selected finally 46 references coming from countries as diverse as Brazil, the United States, India, Kenya, New Zealand, Peru, Zímbabwe, Australia and Spain, as well as international entities Africa, Latin America or the United Nations. These documents are analyzed in detail. They seek land use raw mainly in the form of mud, compressed earth block and tapial, for use in the construction of walls in buildings with simple burdens of average height and limited.

Summary: The purpose of this Ph.D. Thesis has been evaluating various strategies for opening and closing windows zenith and lateral tunnel greenhouses type widely used in areas of the Mediterranean climate. Have been obtained for this data along two campaigns in a greenhouse located in the Campos Practices ETSI Agronomists built in galvanized steel and covered methacrylate. The windows providing ventilation were at the top and side of the greenhouse, the first being called window zenith, covering an area of 17.5x0.7 m2 and the second, known as side window, covering almost the entire length of the greenhouse, covering an area of 18x0.5 m2. In a first phase, during the 2001-2002 campaign, took data from the inside temperature for ten different strategies at the opening and closing windows. With such data was adjusted a simple climate model dynamic behavior of the temperature inside the greenhouse according to the different degree of openness of the windows, as well as solar radiation and air temperature outside the greenhouse. The error using the model in these circumstances was 1.63Â ° C. The above model was validated in the campaign 2002-2003 with the data obtained, in this case to follow four strategies significant. Using the model can be obtained proceeded to perform simulations of five new control strategies, data on actual temperature outside. In these simulations found that the optimal control strategy for the opening and closing windows is one that opens the window down into two sections, depending on the inside temperature. If this openness is not sufficient, then opened the side window. This method combines simplicity, a variation internal thermal acceptable and a low of operations on windows.
