En este contexto, la rehabilitación energética de edificios es una línea de trabajo prioritaria que actúa sobre el parque edificado, y los edificios públicos deben ser un modelo o ejemplo para impulsar este tipo de actuaciones. Los centros docentes, con un potencial de ahorro muy importante y con unos consumos energéticos asociados básicamente a dos grandes conceptos, la iluminación y la climatización, pueden considerarse como un laboratorio de investigación en cuanto a eficiencia energética. A partir de las experiencias adquiridas durante más de 10 años se ha desarrollado una metodología de análisis para la intervención en edificios docentes en Barcelona con los siguientes objetivos: definir los indicadores estratégicos para identificar las oportunidades de ahorro, evaluar las posibles medidas de reducción de consumos a partir de la limitación de la demanda, analizar y dar contenido al papel de cada uno de los actores que intervienen en las estrategias de uso y gestión de los edificios escolares y establecer los criterios que deben considerarse para realizar las futuras intervenciones de rehabilitación energética. El método, como manera de pensar ordenadamente, ha de permitir optimizar los recursos y descubrir les rutas de trabajo que nos conduzcan al objetivo final: reducir el consumo energético del parque edificado http://hdl.handle.net/2117/18930 Title: Construction processes using mobile augmented reality: a study case in building engineering degree Authors: Sánchez Riera, Alberto; Redondo Domínguez, Ernesto; Fonseca Escudero, David; Navarro Delgado, Isidro 2013-04-22T14:37:35Z http://hdl.handle.net/2117/18792 Title: Implementation of augmented reality in “3.0 learning” methodology: case studies with students of architecture degree Authors: Redondo Domínguez, Ernesto; Navarro Delgado, Isidro; Sánchez Riera, Alberto; Fonseca, David 2013-04-15T12:37:52Z http://hdl.handle.net/2117/18783 Title: Prefabricación en rehabilitación: el panel de madera contralaminada en el edificio de Ca la Dona Authors: Bestraten Castells, Sandra Cinta; Hormias Laperal, Emilio Abstract: En la rehabilitación del edificio histórico de la C/Ripoll nº25 de Barcelona para su adaptación a uso público se ha realizado una apuesta estructural innovadora realizando una substitución funcional de los forjados con paneles de madera contralaminada y conservando los forjados existentes validados por la diagnosis previa. Los forjados con paneles de madera contralaminada resuelven de forma respetuosa el comportamiento estructural de la edificación existente, dado que no modifican el estado general de cargas del edificio histórico. Su reducido peso propio permite que los muros estructurales originales sigan asumiendo su función portante, al mismo tiempo que el nuevo forjado confiere un mayor grado de estabilidad y arriostramiento a todo el conjunto. El montaje totalmente en seco conlleva la supresión de aportaciones de humedad de obra no deseadas sobre los materiales tradicionales del edificio. Esta prefabricación flexible permite reducir considerablemente el tiempo de ejecución, mejorar la seguridad en obra y plantear a largo plazo la reversibilidad de la intervención y la recuperación íntegra del material para su reciclaje sin generar residuos de derribo. Este proyecto abre un camino a la prefabricación de las soluciones utilizadas en rehabilitación arquitectónica permitiendo cumplir con los condicionantes normativos vigentes, e incorporando principios de sostenibilidad en el refuerzo estructural de la edificación existente. // Concerning restoring the historic building of 25th Ripoll Street in Barcelona for his adaptation to public use, it has been made an innovative structure solution based on a flooring functional substitution with cross-laminated timber panels while preserving the existent floorings validated by the initial diagnosis. Cross-laminated timber panels floorings respectfully resolve the structural behavior of the existing building as they do not alter the overall charge of the historic building. Its low weight enables the original structural walls to continue as load bearing, while the new flooring confers a greater degree of stability and bracing to the whole building. Completely dry assembly allows the removal of unwanted dump on the original building materials. This flexible prefabrication significantly reduces implementation time, improve safety at work and bring long-term reversibility of the intervention and the full recovery of material for recycling without generating demolition waste. This project opens a way to the prefabrication of the solutions used in architectural restoration, meeting the current regulatory constraints, while incorporating sustainability principles into the structural reinforcement of the existing building.

The addition of montmorillonite clay promoted foaming and the formation of finer and more homogeneous cellular structures, resulting in foams with compressive elastic moduli and collapse stresses lower than that of the unfilled polyurethane foams. However, a comparative analysis versus the foams’ relative density demonstrated that both mechanical properties follow one single trend for the two materials. The combination of montmorillonite and metal reinforcement further reduced the cell size of foams, ultimately resulting in foams with similar mechanical properties for considerably lower relative densities. Although no important differences in thermal conductivity were found for the polyurethane foams with adding montmorillonite, the incorporation of the metal reinforcement led to considerably higher thermal conductivities, its value increasing with increasing relative density. 2013-04-11T15:37:03Z http://hdl.handle.net/2117/18774 Title: Model for enhancing integrated identification, assessment, and operational control of on-site environmental impacts and health and safety risks in construction firms Authors: Gangolells Solanellas, Marta; Casals Casanova, Miquel; Forcada Matheu, Núria; Fuertes Casals, Alba; Roca Ramon, Xavier Abstract: Certifiable management-system standards apply similar management techniques and principles, but each system still tends to have a separate structure in construction companies. Research and practice have demonstrated that management tasks may be duplicated when standards are implemented in parallel. Consequently, integrated management systems are strongly advocated. However, existing literature demonstrates that the integration of planning and control instruments involves a high level of uncertainty. This paper presents an innovative model to enhance the integration of environmental- and health and safety – management systems in construction companies, focusing on the subsystems for identifying, assessing, and operationally controlling environmental aspects and health and safety hazards and using risk as an integrating factor. The findings of this study have direct implications for both designers and contractors because the model helps to explicitly consider on-site environmental impacts and construction-worker safety during the design process and offers on-site guidance to eliminate the remaining impacts and risks or reduce them to acceptable levels. A case study is reported to illustrate the practical use of the proposed model and its benefits. 2013-04-11T14:36:42Z http://hdl.handle.net/2117/18738 Title: Influence of building type on post-handover defects in housing Authors: Forcada Matheu, Núria; Macarulla Martí, Marcel; Fuertes Casals, Alba; Casals Casanova, Miquel; Gangolells Solanellas, Marta; Roca Ramon, Xavier Abstract: Clients’ lack of involvement in defining quality requirements for dwellings built by developers leads to a perception of poor quality at the time of purchase. The research presented in this paper aims to broaden previous research on defects by analyzing the defects that remain in the post-handover stage, which usually lasts 12 months after the handover period, and identifying the factors that influence the appearance of these defects, determining whether a significant difference exists in the quality of the two main residential building types built by developers: flats and detached houses. It also analyzes and discusses the areas and elements in which the defects were detected. The data were obtained from client complaint forms completed after the handover of 95 dwellings in Spain. The data were then statistically analyzed using a t-test analysis, a Pearson’s parametric correlation, and a chi-square test. The research reveals that clients detect more defects in flats than in detached houses. The lower quality of the materials used in flats and the tighter schedule to which flats are subject may cause these differences. 2013-04-09T14:50:53Z http://hdl.handle.net/2117/18416 Title: Assessment of residential defects at post-handover Authors: Forcada Matheu, Núria; Macarulla Martí, Marcel; Love, Peter E.D. Abstract: In Spain, the Ley de Ordenación de la Edificación (Building Regulation Act) has established compulsory warranties to ensure that buildings meet basic requirements with regard to functionality, general safety and structure, fireproofing, and use and habitability. Despite the requirements of this regulatory body, defects in newly built dwellings remain a pervasive problem, which has resulted in a plethora of complaints to the Instituto Nacional del Consumo (National Institute for Consumers ’ Protection), which deals with consumer protection in Spain. In this paper, a total of 2,351 post-handover defects derived from four Spanish builders and seven residential developments are classified according to their location, subcontract, and element. The research reveals that the most common defects identified by customers at handover were incomplete tile grouting and incorrect fixtures and fittings in toilets. In addition, failure to apply second coats of paint to walls was deemed a problematic issue. Typical surface/appearance defects were found to include floor or wall unevenness, stains, mess, and small cracks and marks, primarily caused by lack of protection. In areas where fixtures, fittings, and finishes were of a similar nature, such as the kitchen and bathroom, defect types also arose. Determining the location, subcontract, and element where defects occur in residential buildings can provide invaluable knowledge about areas where builders are likely to make errors or mistakes or take deliberate shortcuts during construction. Thus, emphasis on quality control and supervision of subcontract trades, especially in the identified areas, and during the final stages of residential construction, are critical to ensure that defects are reduced. 2013-03-19T16:04:48Z http://hdl.handle.net/2117/18363 Title: Le parc bâti en Espagne face aux enjeux énergétiques Authors: Casanovas Boixereu, Francesc X. Abstract: Le secteur de la construction de logements a été fortement spéculatif en Espagne au détriment de la réhabilitation et du renouvellement urbain. Le parc existant et les quartiers anciens sont donc aujourd’hui fortement dégradés avec des habitants démunis, voire en situation de précarité ou de pauvreté. Il est urgent de créer un cadre législatif et réglementaire favorable à la réhabilitation, et qui respecte les exigences des directives européennes (notamment au regard de l’efficacité énergétique). Ceci permettra par ailleurs au secteur de la réhabilitation de redynamiser l’économie espagnole et de créer des emplois. 2013-03-18T11:41:35Z http://hdl.handle.net/2117/18200 Title: La informació ambiental en el sector de la construcció Authors: Alfaro Garrido, Licinio José Abstract: L’actual nova consciència de protecció envers el medi ambient fa que el sector de la construcció, paral·lelament a la crisi que pateix, estigui fent una reestructuració dels seus valors: està començant a incorporar nous criteris d’anàlisi i de presa de decisions en el seu funcionament.

This paper aims to review the most relevant contributions on the specific literature in order to design a survey to test for the parameters that affect effective communication among Construction Agents (CA), i.e. PM’s, builder, designer and other professionals participants, during the construction process of the project. The survey will be based on the experience and perceptions of the corresponding professionals in Spain. The availa bility of these par ameters is crucial and it represents basic information for developing procedures and tools for the evaluation and selection management of CAs. 2013-03-07T14:44:23Z http://hdl.handle.net/2117/18104 Title: La integración de sistemas activos de producción energética en la envolvente del edificio : taxonomía constructiva Authors: París Viviana, Oriol Abstract: Analisis de una metodología de clasificación para la integración de los sistemas fotovoltaicos en la envolvente del edificio.
