This work introduces an innovative urinal for public convenience, that promotes at the same time water reuse and personal higiene, in a safe and economical way . Furthermore it demonstrates the latest technology and its technical and economical viabillity of utilization in new and already existing buildings facilities. This new model of personal higiene equipment offers as main benefits the improved economy with subsequent decrease in drinkable water consumption, sanitary safety, low cost and easy installation due to its simplicity and to the fact that it can be installed in already existing facilities. The proposal is constituted by a higienic, ecological and smart system for flushing of public urinals. It is a conjugated system of lavatory and urinal that reuses hands higienization water from the lavatory for flushing purpose. The proposed urinal can be operated manually or automatically by means of a presential sensor. The system promotes drinkable water economy by a rational utilization by avoiding the use of waste water from hand washing in place of clean water for flushing. The proposed equipment increases the economy of clean water in a simple and economical way and it can be installed in any type of public lavatory facilitie such as schools, public buildings, hospitals, commercial buildings, bus terminals, airports, stadiums, parking buildings and shopping centers. Additional benefits of the proposed system is the suggestion of hands washing before and after the use of the urinal without contamination risks from focet handling.and render more attractive the installation for a rational use of clean water in commercial and industrial buildings. Pay-back has shown to be very attractive for a number of internal return rates and also very attractive from the point of view of environmental protection.

Exposure to the Asp f 1 allergen in nonindustrial occupational environments

Sick Building Syndrome is a prevalent problem with patient complaints similar to typical allergy symptoms. Unlike most household allergens, the Asp f 1 allergen is conceivably ubiquitous in the work environment. This project examined levels of the Asp f 1 allergen in office and non-industrial occupational environments, and studied the bioaerosol and dust reservoirs of Aspergillus fumigatus responsible for those levels. ^ Culturable bioaerosols of total mesophilic fungi were sampled with Andersen N6 impactors. Aggressive airborne and bulk dust samples were concurrently collected and assayed for Asp f 1. Bulk dusts were selectively cultured for A. fumigatus. Samples were collected during both wet and dry climatological conditions to examine the possibility of Asp f 1 increases due to fungal growth blooms. ^ Only very low levels of Asp f 1 were detected in relatively few samples. Analysis of wet versus dry period samples showed no differences in Asp f 1 levels, although A. fumigatus counts from dusts did fluctuate significantly with exterior moisture events as did indoor prevalence of total colony forming units. These results indicate that even in the presence of elevated fungal concentrations, levels of Asp f 1 are extremely low. These levels do not correlate with climatological moisture events, despite distinct fungal blooms in the days immediately following those events. Non-industrial office buildings devoid of indoor air quality issues did not demonstrate significant levels or occurrence of Asp f 1 contamination in the geographical region of this study. ^

ClimApp: A Novel Approach of an Intelligent HVAC Control System

This paper describes a novel deployment of an intelligent user-centered HVAC (Heating, Ventilating and Air Conditioner) control system. The main objective of this system is to optimize user comfort and to reduce energy consumption in office buildings. Existing commercial HVAC control systems work in a fixed and predetermined way. The novelty of the proposed system is that it adapts dynamically to the user and to the building environment. For this purpose the system architecture has been designed under the paradigm of Ambient Intelligence. A prototype of the system proposed has been tested in a real-world environment.

Instituto de Sistemas Fotovoltaicos de Concentración concentration photovoltaics hybrid system first year of operation and improvements

A photovoltaic (PV) hybrid system combines PV with other forms of electricity generation, usually a diesel generator. The system presented in this paper uses concentration photovoltaic (CPV) as the main generator in combination with a storage system and the grid, configured as the backup power supply. The load of the system consists of an air conditioning system of an office building. This paper presents the results obtained from the first months of operation of the CPV hybrid system installed at Instituto de Sistemas Fotovoltaicos de Concentración facilities together with exhaustive simulations in order to model the system behaviour and be able to improve the self-consumption ratio. This system represents a first approach to the use of a CPV in office buildings complemented by an existing AC-coupled hybrid system. The contribution of this paper to the analysis of this new system and the existing tools available for its simulation, at least a part of it, can be considered as a starting point for the development of these kinds of systems.

Enhancing regression models for complex systems using evolutionary techniques for feature engineering

This work proposes an automatic methodology for modeling complex systems. Our methodology is based on the combination of Grammatical Evolution and classical regression to obtain an optimal set of features that take part of a linear and convex model. This technique provides both Feature Engineering and Symbolic Regression in order to infer accurate models with no effort or designer's expertise requirements. As advanced Cloud services are becoming mainstream, the contribution of data centers in the overall power consumption of modern cities is growing dramatically. These facilities consume from 10 to 100 times more power per square foot than typical office buildings. Modeling the power consumption for these infrastructures is crucial to anticipate the effects of aggressive optimization policies, but accurate and fast power modeling is a complex challenge for high-end servers not yet satisfied by analytical approaches. For this case study, our methodology minimizes error in power prediction. This work has been tested using real Cloud applications resulting on an average error in power estimation of 3.98%. Our work improves the possibilities of deriving Cloud energy efficient policies in Cloud data centers being applicable to other computing environments with similar characteristics.

Contribución a la localización en interiores basada en comunicaciones inalámbricas

Determinar con buena precisión la posición en la que se encuentra un terminal móvil, cuando éste se halla inmerso en un entorno de interior (centros comerciales, edificios de oficinas, aeropuertos, estaciones, túneles, etc), es el pilar básico sobre el que se sustentan un gran número de aplicaciones y servicios. Muchos de esos servicios se encuentran ya disponibles en entornos de exterior, aunque los entornos de interior se prestan a otros servicios específicos para ellos. Ese número, sin embargo, podría ser significativamente mayor de lo que actualmente es, si no fuera necesaria una costosa infraestructura para llevar a cabo el posicionamiento con la precisión adecuada a cada uno de los hipotéticos servicios. O, igualmente, si la citada infraestructura pudiera tener otros usos distintos, además del relacionado con el posicionamiento. La usabilidad de la misma infraestructura para otros fines distintos ofrecería la oportunidad de que la misma estuviera ya presente en las diferentes localizaciones, porque ha sido previamente desplegada para esos otros usos; o bien facilitaría su despliegue, porque el coste de esa operación ofreciera un mayor retorno de usabilidad para quien lo realiza. Las tecnologías inalámbricas de comunicaciones basadas en radiofrecuencia, ya en uso para las comunicaciones de voz y datos (móviles, WLAN, etc), cumplen el requisito anteriormente indicado y, por tanto, facilitarían el crecimiento de las aplicaciones y servicios basados en el posicionamiento, en el caso de poderse emplear para ello. Sin embargo, determinar la posición con el nivel de precisión adecuado mediante el uso de estas tecnologías, es un importante reto hoy en día. El presente trabajo pretende aportar avances significativos en este campo. A lo largo del mismo se llevará a cabo, en primer lugar, un estudio de los principales algoritmos y técnicas auxiliares de posicionamiento aplicables en entornos de interior. La revisión se centrará en aquellos que sean aptos tanto para tecnologías móviles de última generación como para entornos WLAN. Con ello, se pretende poner de relieve las ventajas e inconvenientes de cada uno de estos algoritmos, teniendo como motivación final su aplicabilidad tanto al mundo de las redes móviles 3G y 4G (en especial a las femtoceldas y small-cells LTE) como al indicado entorno WLAN; y teniendo siempre presente que el objetivo último es que vayan a ser usados en interiores. La principal conclusión de esa revisión es que las técnicas de triangulación, comúnmente empleadas para realizar la localización en entornos de exterior, se muestran inútiles en los entornos de interior, debido a efectos adversos propios de este tipo de entornos como la pérdida de visión directa o los caminos múltiples en el recorrido de la señal. Los métodos de huella radioeléctrica, más conocidos bajo el término inglés “fingerprinting”, que se basan en la comparación de los valores de potencia de señal que se están recibiendo en el momento de llevar a cabo el posicionamiento por un terminal móvil, frente a los valores registrados en un mapa radio de potencias, elaborado durante una fase inicial de calibración, aparecen como los mejores de entre los posibles para los escenarios de interior. Sin embargo, estos sistemas se ven también afectados por otros problemas, como por ejemplo los importantes trabajos a realizar para ponerlos en marcha, y la variabilidad del canal. Frente a ellos, en el presente trabajo se presentan dos contribuciones originales para mejorar los sistemas basados en los métodos fingerprinting. La primera de esas contribuciones describe un método para determinar, de manera sencilla, las características básicas del sistema a nivel del número de muestras necesarias para crear el mapa radio de la huella radioeléctrica de referencia, junto al número mínimo de emisores de radiofrecuencia que habrá que desplegar; todo ello, a partir de unos requerimientos iniciales relacionados con el error y la precisión buscados en el posicionamiento a realizar, a los que uniremos los datos correspondientes a las dimensiones y realidad física del entorno. De esa forma, se establecen unas pautas iniciales a la hora de dimensionar el sistema, y se combaten los efectos negativos que, sobre el coste o el rendimiento del sistema en su conjunto, son debidos a un despliegue ineficiente de los emisores de radiofrecuencia y de los puntos de captura de su huella. La segunda contribución incrementa la precisión resultante del sistema en tiempo real, gracias a una técnica de recalibración automática del mapa radio de potencias. Esta técnica tiene en cuenta las medidas reportadas continuamente por unos pocos puntos de referencia estáticos, estratégicamente distribuidos en el entorno, para recalcular y actualizar las potencias registradas en el mapa radio. Un beneficio adicional a nivel operativo de la citada técnica, es la prolongación del tiempo de usabilidad fiable del sistema, bajando la frecuencia en la que se requiere volver a capturar el mapa radio de potencias completo. Las mejoras anteriormente citadas serán de aplicación directa en la mejora de los mecanismos de posicionamiento en interiores basados en la infraestructura inalámbrica de comunicaciones de voz y datos. A partir de ahí, esa mejora será extensible y de aplicabilidad sobre los servicios de localización (conocimiento personal del lugar donde uno mismo se encuentra), monitorización (conocimiento por terceros del citado lugar) y seguimiento (monitorización prolongada en el tiempo), ya que todos ellas toman como base un correcto posicionamiento para un adecuado desempeño. ABSTRACT To find the position where a mobile is located with good accuracy, when it is immersed in an indoor environment (shopping centers, office buildings, airports, stations, tunnels, etc.), is the cornerstone on which a large number of applications and services are supported. Many of these services are already available in outdoor environments, although the indoor environments are suitable for other services that are specific for it. That number, however, could be significantly higher than now, if an expensive infrastructure were not required to perform the positioning service with adequate precision, for each one of the hypothetical services. Or, equally, whether that infrastructure may have other different uses beyond the ones associated with positioning. The usability of the same infrastructure for purposes other than positioning could give the opportunity of having it already available in the different locations, because it was previously deployed for these other uses; or facilitate its deployment, because the cost of that operation would offer a higher return on usability for the deployer. Wireless technologies based on radio communications, already in use for voice and data communications (mobile, WLAN, etc), meet the requirement of additional usability and, therefore, could facilitate the growth of applications and services based on positioning, in the case of being able to use it. However, determining the position with the appropriate degree of accuracy using these technologies is a major challenge today. This paper provides significant advances in this field. Along this work, a study about the main algorithms and auxiliar techniques related with indoor positioning will be initially carried out. The review will be focused in those that are suitable to be used with both last generation mobile technologies and WLAN environments. By doing this, it is tried to highlight the advantages and disadvantages of each one of these algorithms, having as final motivation their applicability both in the world of 3G and 4G mobile networks (especially in femtocells and small-cells of LTE) and in the WLAN world; and having always in mind that the final aim is to use it in indoor environments. The main conclusion of that review is that triangulation techniques, commonly used for localization in outdoor environments, are useless in indoor environments due to adverse effects of such environments as loss of sight or multipaths. Triangulation techniques used for external locations are useless due to adverse effects like the lack of line of sight or multipath. Fingerprinting methods, based on the comparison of Received Signal Strength values measured by the mobile phone with a radio map of RSSI Recorded during the calibration phase, arise as the best methods for indoor scenarios. However, these systems are also affected by other problems, for example the important load of tasks to be done to have the system ready to work, and the variability of the channel. In front of them, in this paper we present two original contributions to improve the fingerprinting methods based systems. The first one of these contributions describes a method for find, in a simple way, the basic characteristics of the system at the level of the number of samples needed to create the radio map inside the referenced fingerprint, and also by the minimum number of radio frequency emitters that are needed to be deployed; and both of them coming from some initial requirements for the system related to the error and accuracy in positioning wanted to have, which it will be joined the data corresponding to the dimensions and physical reality of the environment. Thus, some initial guidelines when dimensioning the system will be in place, and the negative effects into the cost or into the performance of the whole system, due to an inefficient deployment of the radio frequency emitters and of the radio map capture points, will be minimized. The second contribution increases the resulting accuracy of the system when working in real time, thanks to a technique of automatic recalibration of the power measurements stored in the radio map. This technique takes into account the continuous measures reported by a few static reference points, strategically distributed in the environment, to recalculate and update the measurements stored into the map radio. An additional benefit at operational level of such technique, is the extension of the reliable time of the system, decreasing the periodicity required to recapture the radio map within full measurements. The above mentioned improvements are directly applicable to improve indoor positioning mechanisms based on voice and data wireless communications infrastructure. From there, that improvement will be also extensible and applicable to location services (personal knowledge of the location where oneself is), monitoring (knowledge by other people of your location) and monitoring (prolonged monitoring over time) as all of them are based in a correct positioning for proper performance.

Integración de sistemas fotovoltaicos en edificios de oficinas en bajas latitudes: estudio del balance energético aplicado a Brasil

La hipótesis que inspiró esta tesis sostiene que la integración de componentes fotovoltaicos en los cerramientos opacos y sombreamientos de huecos acristalados de edificios de oficinas en sitios ubicados en bajas latitudes, tomando como el ejemplo el caso concreto de Brasil, podría incrementar su eficiencia energética. Esta posibilidad se basa en el bloqueo de una parte significativa de la irradiación solar incidente en estos edificios, reduciendo así las cargas térmicas para la climatización y a la vez transformándola en energía eléctrica, a tal punto que se amortizan los costes de inversión en plazos aceptables a través de los ahorros en la demanda de energía. Para verificar esta hipótesis de partida se ha propuesto como objetivo general analizar la integración de elementos fotovoltaicos en cubiertas, muros opacos y sombreamiento de huecos acristalados desde la óptica del balance energético térmico y eléctrico. Inicialmente se presenta y analiza el estado del arte en los temas estudiados y la metodología de investigación, de carácter teórico basada en cálculos y simulaciones. A partir de un modelo tipo de edificio de oficinas situado en Brasil, se definen cuatro casos de estudio y una serie de parámetros, los cuales se analizan para siete latitudes ubicadas entre -1,4° y -30°, separadas las unas de las otras por aproximadamente 5°. Se presentan y discuten los resultados de más de 500 simulaciones para los siguientes conceptos: - recurso solar, desde la perspectiva de la disponibilidad de irradiación solar en distintas superficies de captación apropiadas para la integración de sistemas solares fotovoltaicos en edificaciones en bajas latitudes; - análisis de sombras, con objetivo de identificar los ángulos de sombras vertical (AVS) para protección de huecos acristalados en edificios de oficinas; - balance energético térmico, para identificar el efecto térmico del apantallamiento provocado por componentes fotovoltaicos en cubiertas, muros opacos y parasoles en ventanas en las cargas de refrigeración y consecuentemente en las demandas de energía eléctrica; - balance energético eléctrico, contrastando los resultados del balance térmico con la energía potencialmente generada en las envolventes arquitectónicas bajo estudio; - análisis económico, basado en un escenario de precios de la tecnología fotovoltaica de un mercado maduro y en la política de inyección a la red marcada por la actual normativa brasileña. Se han verificado los potenciales de ahorro económico que los sistemas activos fotovoltaicos podrían aportar, y asimismo se calculan diversos indicadores de rentabilidad financiera. En suma, esta investigación ha permitido extraer conclusiones que contribuyen al avance de la investigación y entender las condiciones que propician la viabilidad de la aplicación de componentes fotovoltaicas en las envolventes de edificios en Brasil, y hasta un cierto punto en otros países en latitudes equivalentes. ABSTRACT The hypothesis that inspired this thesis sustains that integration of photovoltaic components in the opaque envelope and shading elements of office buildings placed at low-latitude countries, using the specific case of Brazil, could increase its energy efficiency. This is possible because those components block a significant part of the incident solar irradiation, reducing its heating effect on the building and transforming its energy into electricity in such a way that the extra investments needed can be paid back in acceptable periods given the electricity bill savings they produce. In order to check this hypothesis, the main goal was to analyze the thermal and electrical performance of photovoltaic components integrated into roofs, opaque façades and window shadings. The first step is an introduction and discussion of the state of the art in the studied subjects, as well as the chosen methodology (which is theoretical), based on calculations and simulations. Starting from an office building located in Brazil, four case studies and their parameters are defined, and then analyzed, for seven cities located between latitudes -1.4° and -30°, with an approximate distance of 5° separating each one. Results of more than 500 simulations are presented and discussed for the following concepts: - Solar resource, from the perspective of irradiation availability on different surfaces for the integration of photovoltaic systems in buildings located at low latitudes; - Shading analysis, in order to determine the vertical shading angles (VSA) for protection of the glazed surfaces on office buildings; - Thermal energy balance, to identify the screening effect caused by photovoltaic components on roofs, opaque façades and window shadings on the cooling loads, and hence electricity demands; - Electric energy balance, comparing thermal energy balance with the energy potentially generated using the active skin of the buildings; - Economic analysis, based on a mature-market scenario and the current net metering rules established by the Brazilian government, to identify the potential savings these photovoltaic systems could deliver, as well as several indicators related to the return on the investment. In short, this research has led to conclusions that contribute to the further development of knowledge in this area and understanding of the conditions that favor the application of photovoltaic components in the envelope of office buildings in Brazil and, to a certain extent, in other countries at similar latitudes.

Jacques Tati : vivienda experimental y espacio de trabajo a mediados del siglo XX

La obra fílmica del director francés Jacques Tati podría considerarse como el perfecto reflejo del paradigma edificatorio de mediados del siglo XX en plena posguerra europea, una época ávida de transformaciones de las que el cine supo hacerse eco. Particularmente, el cine de Tati refleja las preocupaciones del ciudadano europeo de posguerra sobre las consecuencias de las masivas construcciones erigidas en sus devastados núcleos urbanos y la puesta en práctica de la ciudad funcional propuesta por la Carta de Atenas (1931). Pero, además, el análisis del cine de Jacques Tati permite un acercamiento a la modernidad desde diversos puntos de vista como la movilidad, el diseño urbano, las nuevas construcciones, los espacios de trabajo en los nuevos distritos terciarios, la vivienda -tradicional, moderna y experimental- o el diseño mobiliario en la posguerra. A través de su alter ego -Monsieur Hulot- Tati interacciona curioso con las nuevas construcciones geométricas de paños neutros y cuestiona su ruptura con la tradición edificatoria francesa, enfatizando la oposición entre el pasado nostálgico y la modernidad de las décadas de los 50 y 60, salpicadas por el consumismo feroz del recién estrenado estado de bienestar. La confrontación funcional, volumétrica, estética e incluso cromática entre ambos mundos construidos –el tradicional y el moderno- invita al espectador a un ejercicio de reflexión y crítica sobre la arquitectura moderna de este período en Europa. En particular, la mirada cinematográfica de Tati se centra en dos conceptos fundamentales. Por una parte, su atención se dirige a la famosa casa mecanicista Le Corbuseriana materializada en la ultra-moderna casa Arpel (Mon Oncle, 1958) y proyectada en la misma época en la que se desarrollaban importantes prototipos de vivienda experimental como la Casa de Futuro de Alison y Peter Smithson o las viviendas de Jean Prouvé. Debe ponerse de manifiesto que la crítica de Jacques Tati no se centraba en la arquitectura moderna en sí misma sino en el empleo erróneo que los usuarios pudieran hacer de ella. Por otro lado, Tati centra su atención en el prisma miesiano a través de los bloques de oficinas que conforman la ciudad de Tativille en Playtime (1967). Se trataba de una gran ciudad moderna construida explícitamente para el rodaje de la película y basada en los casi idénticos tejidos urbanos residenciales y terciarios ya en funcionamiento en las principales capitales europeas y norteamericanas en aquellos años. Tativille funcionaría como una ciudad autónoma disponiendo de diversas instalaciones y con el objetivo de integrarse y consolidarse en la trama urbana parisina. Lamentablemente, su destino al final del rodaje fue bien distinto. En definitiva, el análisis de la producción fílmica de Jacques Tati permite un acercamiento a la arquitectura y al urbanismo modernos de posguerra y al contexto socio-económico que favoreció su crecimiento y expansión. Por ello, su obra constituye una herramienta visual muy útil que aún hoy es consultada y mostrada por su claridad y humor y que invita a los ciudadanos –telespectadores- a participar en un ejercicio crítico arquitectónico hasta entonces reservado a los arquitectos. ABSTRACT The film work of French director Jacques Tati could be considered as the perfect reflection of the mid-20th century European post-war building paradigm, a period of time plenty of transformations perfectly echoed by cinema. In particular, Tati’s film work reflects the European post-war citizen’s concerns about the consequences of massive constructions built in their desvastated urban centres, as well as the development of functional cities proposed by the Athens Charter (1931). But, on top of that, an analysis of Jacques Tati’s cinematography allows for an approach to modernity from different perspectives, such as mobility, urban design, new buildings, working spaces in the new tertiary districts, housing -traditional, modern, and experimental-, or furniture design during the post-war period. Embodied by his alter-ego –Monsieur Hulot,- Tati curiously interacts with the new geometric constructions of neutral facades and questions the break with the French building tradition, highlighting the opposition between the nostalgic past and modernity of the 50s and 60s, affected by the fierce consumerism of the new welfare state. The functional, volumetric, aesthetic and even chromatic confrontation between both built worlds –traditional vs modern- invites the viewer to an exercise of meditation and criticism on the European modern architecture of that period. Tati’s film look is particularly focused on two basic concepts: on the one hand, his attention addresses Le Corbusier’s famous mechanistic house which is materialized in the ultra-modern Arpel house (Mon Oncle, 1958) and designed, in turn, when the development of other important experimental dwelling prototypes like Alison and Peter Smithson’s House of the Future or Jean Prouvé´s houses was taking place. It must be highlighted that Jacques Tati’s criticism was not addressed to modern architecture itself but to the wrong use that citizens could make of it. On the other hand, Tati focuses on the Miesian prism through the office buildings that shape the city of Tativille in Playtime (1967). It was a big, modern city built specifically for the film shooting, and based on the almost identical residential and tertiary urban fabrics already active in the main European and American capitals those years. Tativille would work as an autonomous city, having several facilities at its disposal and with the goal of getting integrated and consolidated into the Parisian urban weave. However, its final use was, unfortunately, quite different. In conclusion, an analysis of Jacques Tati’s film production allows for an approach to modern post-war architecture and urbanism, as well as to the socio-economic context that favoured its growth and expansion. As a result of this, Jacques Tati’s film production constitutes a suitable visual tool which, even nowadays, is consulted and shown due to its clarity and humour, and at the same time invites citizens –viewers- to participate in an architectural criticism exercise that, so far, had been reserved to architects.

Certificação da sustentabilidade de edifícios de escritórios corporativos no Brasil.

O crescimento industrial, comercial e de serviços traz para as sociedades mais evoluídas uma série de benefícios, como o desenvolvimento econômico e o crescimento populacional, aliados a maiores oportunidades de emprego e renda. Entretanto, pela falta de uma consciência mais apurada sobre os possíveis impactos negativos de ritmo acelerado de crescimento, acaba-se verificando uma série de problemas sociais e, sobretudo, ambientais. Em razão disso, nos últimos anos, constata-se a preocupação de alguns setores da sociedade na busca do desenvolvimento fundamentado em práticas mais sustentáveis. Isso não tem sido diferente no setor da construção civil. A preocupação com a sustentabilidade nos empreendimentos é tema e foco de diversos eventos, tanto no meio acadêmico, como no profissional e governamental. Particularmente, o segmento de mercado de EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS tem sido alvo de pressão para o uso de práticas mais sustentáveis em todo o seu ciclo de vida, desde sua concepção, projeto, implantação e operação até a sua revitalização.
