Method for assessing consolidated coastal tourist areas and urban regeneration. La costa del sol occidental
(Universidad de Sevilla, Departamento de Construcciones Arquitectónicas, 2015) Gallardo Ramírez, Cristina
The research presented in this abstract, which is in an initial phase, forms part of a future PhD thesis whose objective is the definition of a Methodology to assessment and integral regeneration of the Mediterranean coastal tourist areas in Spain, transformed since the start of tourism as massive activity in the mid-twentieth century. The base of this research is the fact that historic city centres, neighborhoods or brownfields have been the focus of european and national urban regeneration policies up to current, while the interventions to renewal these consolidated tourist areas are limited and mostly have a sectorial character, despite of the important extents of these zones in our country. This Method must offer an answer to three key elements -climate change, health and efficiency- in order to achieve an urban sustainability linked to reductions of the environmental and social cost of the metabolism of urban society, and linked to the respect of the permissible limits of the planet2. - Climate change and mitigation strategies in urban areas. - Health linked to the existence of nearby facilities for daily life, including from a gender perspective; - Efficiency, to reduce the use of land, energy, water, materials and transport demand in urban areas. These key elements are required to propitiate self-sufficient urban areas in their functional and environmental behaviour. The Costa del Sol conurbation between Torremolinos and Marbella, which arose around the N-340, is selected as study case. Its original touristic nodes nowadays used as residential areas, are inserted in a framework mainly occupied by isolated urbanizations destined to residential or second-home tourism. Both nodes and urbanizations will be considered in this research.
Rehabilitation of a single-family housing in Buenos Aires, Argentina, using materials made out of recycled waste
(Universidad de Sevilla, Departamento de Construcciones Arquitectónicas I, 2015) Caruso, Susana Inés; Yajnes, Marta Edith
The purpose of this research is to contribute to the utilization of construction and demolition waste (CDW), while reducing the use of cement and the environmental impact produced by the traditional manufacturing of blocks, bricks and cladding, making construction materials out of elements usually discarded in landfill such as the paper bags of cement, lime, adhesives and additives plus expanded polystyrene from discarded packaging and recycled wood that will be used for molds. It points to the manufacture of durable, affordable, lightweight and with good thermal insulation construction materials. These materials will be applied to the rehabilitation of a single-family housing in the city of Buenos Aires, Argentina, through criteria of sustainable design, as part of the case study within the research project named Mixtures with low proportion of cement or other binders applicable to materials and construction techniques using recycled paper and natural fibers in its composition, which is directed by the authors. The building to rehabilitate dates from 1920 with constructive type of bearing walls in common bricks. Its architectural typology is called "Casa Chorizo". Through expansion carried out in 1957 it was added a second floor with independent concrete structure and common bricks enclosing walls. Due to the expansion of a neighboring house, problems of reduction in solar lighting and moisture filtrations took place. The building presents ceilings and walls with humidities plus fissures, and damaged interior and exterior plasters. It is planned the making of ceiling tiles, walls cladding, furnishing and green wall modules made out of papercrete and natural fibers. It is expected that the use of papercrete in ceilings and walls contribute to regulate rooms moisture, improving theirs acoustic and thermal insulation properties. Materials and molds will be manufactured in situ, made to measure, without causing either garbage or surpluses, this will allow to avoid also the expenses in charters, fuel and emissions due to the transportation of finished materials. The rehabilitation site is intended to be a factory and a school simultaneously, qualifying the workers in a technology that is simple, replicable and environmentally friendly at the same time.
Conservation of materials resources by buildings reuse and on site materials reuse strategies
(Universidad de Sevilla. Escuela Técnica Superior de Arquitectura., 2015) Amoêda, R.; Mercader-Moyano, Pilar
Rethinking buildings and construction activities is a fundamental step towards sustainable construction. Being one of the most materials consumers, changes to current practices in the construction industry are crucial in order to effectively reduce primary resources exploitation, as also to reduce the environmental impacts associated with it. End of life of buildings are opportunities to close the materials loop, by means of building renewal and recovery of components and materials. In this context, building reuse and on site materials reuse have shown to be the most preferable end of life scenarios when compared with off site reuse, recycling, energy recovery and landfill disposal. Moving from demolition to deconstruction is one of the changes that are supposed to happen. Another is to change the materials selection procedures in order to consider also reused materials as a valid option in architectural process. Therefore, surveys to assess reuse potential are needed prior to architectural design in order to look for reuse opportunities and reuse constrains both at the building level and materials level. Such opportunities and constrains comprise building adaptability, building conservation state, mechanical and aesthetic performance of materials, feasibility of components and materials recovery. However, existing buildings were not built to be deconstructed and materials recovery is a labor intensive task, facing obstacles as non reversible connections which usually destroy materials integrity. A case study for building reuse and on site materials reuse is here analised in order to illustrate the theoretical principles and goals that drive the reuse approach, highlighting the environmental benefits by keeping Embodied Energy and thus reducing the Global Warming Potential related to construction activities
Sustainable architecture and traditional rural environment: Moratalla (Murcia, Spain)
(Universidad de Sevilla. Escuela Técnica Superior de Arquitectura., 2015) López Sánchez, Pascual A.; Sánchez Medrano, Francisco J.; Mercader-Moyano, Pilar
This paper attempts to demonstrate the relationship between sustainability and vernacular architecture, being focused on a specific research carried out in the old part of Moratalla, a town in Murcia (Spain).This study has been possible thanks to the collection of 265 field records with in situ data so that quality and quantity can be measured. All these are distinctive parameters of vernacular architecture of the centre in the Middle Ages, what teaches us an important lesson of how traditional construction is environmentally friendly and sustainable, thus leading to more practical bioclimatic architecture. The current study relies on an agreement between the Catholic University of Murcia (UCAM) and the town council of the aforementioned town (Moratalla), what gives an idea of its importance. Some recommendations have been included at the end of the paper to be taken into account by municipal legislation so that our building heritage can be preserved and maintained.
Lightweight construction material made with gypsum and extruded polystyne waste
(Universidad de Sevilla, Departamento de Construcciones Arquitectónicas I, 2015) San-Antonio González, A.; Río Merino, Mercedes Del
Approximately 3.2 million tonnes of synthetic polymers are produced in Spain, from which 14.4% come from the construction industry. From all the waste generated from this material, 55% is disposed in landfills, 17% goes to energy recovery system and only 28% is actually recycled. Extruded Polystyrene (XPS) is one of the most used synthetic polymers and it is used as insulation material in construction industry, generating approximately 5% of waste by weight of its total production in the building process, meaning a high volume of waste due to the low density of the material. This waste is non-biodegradable and hence its proper management is necessary to reduce its environmental impact. However, despite the existence of recycling techniques for XPS, only 30% of this waste is currently recycled, mainly due to the high cost of this process. Therefore, the aim of this study is to analyse the feasibility of reusing XPS waste, obtained from discard construction insulation materials, as a lightweight aggregate in gypsum composites. To this end, several prismatic specimens composed by different XPS waste percentages, different particle sizes with and a fixed consistency at a good workability, were analysed by their density, their shore C surface hardness, their flexural and compressive strength and their thermal behaviour. Results show that it is possible to use XPS waste to produce a lightweight gypsum composite. This aggregate helps reducing density up to 25.5% and improves thermal conductivity up to 30%. However, it also decreases the mechanical strength of the composite significantly, but all composites meet the minimum requirements established for these materials.
Application of sustainability criteria in urban multifamily medium scale: report of two cases in Buenos Aires, Argentina
(Universidad de Sevilla, Departamento de Construcciones Arquitectónicas I, 2015) Mühlmann, Susana; Kozak, Daniel; Yajnes, Marta Edith; Caruso, Susana Inés
This paper presents two case studies of urban middle scale buildings destined to multifamily housing, in which the primary objective taken was the envelope design and selection of materials according to criteria of energy efficiency and sustainability in general. Both were the result of a collaboration between an independent architecture office and research centers of the Faculty of Architecture, Design and Urbanism of the University of Buenos Aires, which provided advice in the area of technology related to project and design. In the first case, the advice focused on the envelope design to improve their hygro-thermal behavior through compliance with the value of u together and the protections and adjustments of openings to guarantee the sunshine of the houses, and the solar thermal installation. In the second one, waste management for direct application of demolitions at the working site on new materials that contribute to reduce the transportation energy expenditure and to the thermal capacity of the envelope was incorporated. The originality that presents the paper lies firstly in the selection of the case studies: typical buildings of the City of Buenos Aires, built without exceptional budgets or conditions. Contrary to some prevailing trend in the practice and study in this field locally, it is proposed to shift the debate to the concrete possibilities of promoting sustainability in urban architecture, and provide casuistry in this regard. Furthermore, the two cases realize modes of articulation between academia and public research and private enterprises, unusual at this scale. It is noteworthy that the research projects that directly and indirectly relate to assessments that provide technical solutions and innovations to the works (such as the design and production processes of the blocks cementitious aggregates coming from recycled materials) are formed by teams led by university professors, and graduate and undergraduate students. The case studies analysis emphasizes the issue of selection, production and materials management with sustainability criteria, within the theoretical framework of materials, environment and health. This is another point that, within this area at the local level, has not received the necessary attention in terms of dissemination of information, legal frameworks, or protocols of implementation.
Renovation of buildings: review of approach and the evaluation of the environmental impact through life cycle assessment
(2015) Vilches Such, Alberto Javier; García Martínez, Antonio; Sánchez-Montañés Macías, Benito
Nowadays, renovation of buildings is a general recommendation in order to reduce the operational energy consumption and their emissions associated. Besides, the renovation of buildings allows reusing materials, increasing the building life service and avoiding the deconstruction and new construction impacts. However, it is necessary to be aware that the intervention itself generate an impact (embodied energy, transportation and construction process), and sometimes, energy systems upgrading does not mean a consumption reduction and it also have influence on the city metabolism. The European Union and the Royal Institute of British Architecture have defined strategies in order to reduce the impact associated to buildings through renovations or refurbishments, however, both approaches have differences in their own standpoint. Besides, there are many concepts and terms associated to renovation that do not allow to clarify the objective with a technical and rigorously perspective. Facing the current uncertainties, life cycle assessment technique allows focusing on an already confirmed methodology in order to evaluate the potential environmental impacts associated to the renovation of buildings. While environmental impact on new construction is highly addressed, publication of refurbishment’s environmental impact is lacking in the academic literature. The used materials in construction phase of conventional building accounts for 20% of the total life cycle impact, while the operation energy is around 80%. However, recent researches show how as we design buildings with lower energy consumption the previous balance is levelling, and thus the weight of the materials on the total impact of the building is around 40% compared to 60% of operating energy. Therefore, in this communication are shown the current approaches and concepts in an international context to define a low environmental impact renovation. Firstly, it is proposed a classification of the renovation impacts according to the rebound effect theory. Secondly, it has been done a review of the academic literature that has used the life cycle assessment to evaluate the renovation of buildings, where convergences and divergences has been found between authors. Finally, it concludes highlighting those common perspectives and what fields are needed to develop in order to get a holistic and global approach of the environmental impact of renovation of buildings.
Analysis of the variables that affect the strength of concrete with recycled aggregates from prefabricated pipes
(Universidad de Sevilla, Departamento de Construcciones Arquitectónicas I, 2015) Terela, Ester; Letelier, Viviana; Osses, Rodriguez; Cárdenas, Juan Pablo; Moriconi, Giacomo
The influence of several parameters in the compressive and flexural strength of concrete with recycled aggregates is analyzed. The concretes are dosed for a compressive strength of 30MPa. The recycled aggregates are obtained from debris of prefabricated concrete pipes with a compressive strength of 20MPa. Four variables are considered in this analysis: the percentage of natural course aggregates that are replaced by recycled ones; the amount of mortar adhered to the surface of the aggregates, that will be reduced applying mechanical abrasion processes instead of the chemical traditional ones; the maximum size of the replaced aggregates and the percentage of cement addition specified in the dosing. Taguchi’s statistical method is used considering three levels for each of the four parameters to determine their effects on the material behavior, minimizing the number of the experimental tests required. The tests are performed after curing the samples during 28 and 90 days. The three levels for each parameter are stablished after former studies and/or previous experimental tests. The results are quantified through the analysis of variance methodology (ANOVA), to determine which of the variables has higher effects in the final strengths. The results show that materials with equivalent compressive strengths to those of a control concrete can be obtained restricting the percentage of replaced aggregates to 30% and reducing the amount of adhered mortar through abrasion processes, when the samples have been cured for 28 days. The effect of the size of the recycled aggregates gains significance after 90 days of curing, while the amount of cement addition controls the flexural strength. These results indicate that materials with equivalent mechanical properties to those of a control concrete can be obtained by controlling several parameters, allowing the reuse of debris and reducing the amount of natural course aggregates needed significantly.

User empowerment as environmental co-manager agent of a building through gamification
(Universidad de Sevilla, Departamento de Construcciones Arquitectónicas I, 2015) Cuerdo Vilches, María Teresa; Navas-Martín, M.A
Human behavior on games has been widely analyzed from the psychological and ethnological fields, for its sociocultural implications. Today, immersed in the society of knowledge and digital culture, we are always connected, so that access to social networks, mobile apps, videos, and examples of gamification is so utterly familiar that sometimes we are not aware of it. The application of this term is being carried out for some decades to develop and elaborate marketing strategies, decision-making, even in areas such as health, promoting healthier behaviors into habits. Gamification consists of applying elements and techniques of game-design in contexts that are not really games. Why apply it in building environmental management? There is a clear problem when implementing strategies of energy savings and efficiency, derived from two distinct issues: users do not know the power of action they have on building environmental management when living / working; and since they ignore it, they are not involved, or not enough. Environmental management in a building often depends on a shortlist of people who are often reduced to Management and Maintenance teams. But, What about users? Can they find comfort in buildings of a certain size? Do they know how to help save energy or use it more efficiently than turning off lights and electronic devices once finished the daily task? The potential of users as actors and part of the whole social team, their empowerment once are aware of that, and beyond, quantifying their action and getting feedback to see how well they are doing, is proposed by gamification methodology. This methodology requires a prior analysis of the user type, objective, implementing game elements (mechanical, dynamic and play components), scope, and uncertainties. After initial training on the operation of the building environmental management, users are involved as co-managers, through some media support that reflects their daily activities and their inclusion in the overall calculation of building management. Involving users as well, would be a great achievement especially in tertiary and unique buildings.
Use of fine recycled aggregates form construction and demoliton waste, CDW, in masonry mortar manufacturing
(Universidad de Sevilla, Departamento de Construcciones Arquitectónicas I, 2015) Saiz Martínez, P; González Cortina, M.; Fernández Martínez, F
This research aims to study the feasibility of incorporating fine fraction of recycled aggregates coming from construction and demolition waste in masonry mortars productions, implying a new way for CDW recycling. For this reason, three samples of fine recycled aggregates have been used: one of them was obtained from concrete recycling, one from ceramic recycling and one from mixed recycling line. The volumetric cement-to-aggregate ratio used to perform the tests were 1:3 and 1:4, and the replacement percentages for three types of recycled aggregates were 50%, 75% and 100%. Physical characterization of recycled aggregates shows a continuous size distribution curve, lower density and higher absorption, that makes the use of additive necessary to obtain workable mortars. The main crystalline phases determined are calcite, quartz and gypsum. Compression and flexural strength, bonding strength and shrinkage tests revealed poorer performance of recycled mortars compared to the mortars fabricated with natural sand. However, obtained values are within the limits established by the standards and manufactures. Therefore, this study shows the real possibility to substitute 100% of natural sand with studied recycled aggregates in mortar production.
Influence of daylight in urban design as a tool towards a more sustainable city
(Universidad de Sevilla. Escuela Técnica Superior de Arquitectura., 2015) Fernández Expósito, Manuel; Moreno-Rangel, David; Esquivias Fernández, Paula Matilde; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I; Mercader-Moyano, Pilar; Universidad de Sevilla. TEP130: Arquitectura, Patrimonio y Sostenibilidad: Acustica, Iluminación, Óptica y Energía
Issues of sunlight and daylighting condition for design of the buildings has had little research and few practical applications among other things, because of the absence of national or local minimum requirements. If we focus on the urban scale, awareness and the number of papers addressing this subject is almost inexistent. Among the principles of bioclimatic urban, some authors like José Fariña Tojo or José Manuel Naredo determine planning criteria which can be drawn basics that directly affect the urban design. First, it is essential structural roads that respond to sunlight requirements for getting optimal orientations for the maximum utilization of natural light both for the street and for buildings annexed. Besides, this road has to incorporate an appropriate vegetation to the requirements of humidity and environmental evaporation (trying to minimize thermal loads), getting all together, a urban morphology with well oriented facades and an appropriate proportion of courtyards. The paper will analyze how most relevant urban parameters influence the sunlight inside the building, assessing this influence from the point of view of sustainability. We consider parameters of traditional urban, such as height, width of the street or orientation, such as vegetation and pavement or materiality of the facades. As a case study, we chose a city with warm weather and between 30-40 ° latitude as Sevilla. As an example, we study a street that belong to morphology expansion district. In conclusion, we will carry out an evaluation of the degree of influence each parameter has to improve daylighting conditions inside the building, trying to determine which ratio width and high of a street is the most optimal to achieve optimum use of daylight and therefore greater energy savings.
Compressed earth blocks, their thermal delay and environmental impact
(Universidad de Sevilla. Escuela Técnica Superior de Arquitectura., 2015) Roux Gutiérrez, Rubén Salvador; Velazquez Lozano, Jesús; Rodríguez Deytz, Homero; Mercader-Moyano, Pilar
This communication is the result of research that addresses the issue of blocks of compressed earth (CEB – Compressed Earth Blocks) thermal properties, to corroborate the advantages of this alternative construction material, conventional materials, to check that these materials can meet the needs of the population in their decent housing construction, improving the quality of life of the user and producing less environmental impact. Thermal tests were simulating the effect of the Sun on a wall, registering the temperature during the tests determining the thermal delay on the walls depending on the material. It is as well as with the results of the tests determined which the optimal material for use as housing enclosure is. On the other hand is the study of the CEB, stabilized with hydroxide of lime and cement, seeking to comply with the Mexican standards, in the section relating to materials for use in masonry buildings and thus verify that these materials comply with quality requirements, as well as conventional materials, coupled with the analysis of the life cycle (LCA) in two populations of BCE's stabilized with cementations seeking to determine their environmental impact and finally to be able to compare them with existing databases of conventional materials.
Growth of vegetation on mining jales to recover green areas of polluted communal open spaces
(Universidad de Sevilla. Escuela Técnica Superior de Arquitectura., 2015) Contreras López, Christopher; López de Juambelz, Rocío; Mercader-Moyano, Pilar
Some mining cities in Mexico have recently undergone a rapid demographic expansion which has led to its urban spots expand to places where there are deposits of mining waste (jales) and occupy these places for human settlement. This causes, among many problems, this type of soils causes dust storms of toxic dust particles to health, vegetation does not develop due to the soils because the structure is not suitable due to the lack of organic material, the compactness of soils preclude roots develop, in addition to the physical and chemical characteristics of soil present heavy metals that affect plant growth. These causes, the green areas of the communal open spaces provided in this settlement, are abandoned because they only can be built without vegetation or non-permeable materials that ward off water seepage to the mining jales. The vegetation in the communal open spaces on these settlements prevents dust storms and improves soil characteristics by re-vegetation processes, so the main objective is obtained by factorial bioassays of plants against the concentration of jal, a palette of plant species capable of growing on deposits of jales to mitigate their harmful effects. The experiment species are Carpobrotus edulis and Sedum Praealtum. These bioassays allow evaluate the plant species against four soil mixtures. One of these with polluted soil another with natural soil as a control and two more with mixed soils in different percentage to improve the quality of polluted soil. Each mixture was compared to establish which species could be adapted to the jal soils and what kind of mixed soils is the fittest to develop plant species. The first results show that even though the plant species present some morphological changes, these plants are able to establish themselves in substrates polluted. Therefore this type of vegetation can begin recovery the green areas of forgotten communal open spaces, plus get habitability and give dignity to these places.

Photocatalytic cement. Pollution reduction and preservation of building coatings
(Universidad de Sevilla, Departamento de Construcciones Arquitectónicas I, 2015) Arto Torres, Ignacio
The environmental awareness of the promoters is one of the fundamental pieces to enable the sustainable development of our cities and it is also a vital work of the technicians involved in the building process to encourage and enliven this awareness among our customers. We know the tools needed to provide housing systems to make them more efficient, by involving and implicating the promoter throughout the process. Furtehermore, we are able to design and build homes that contribute to improve the environment in which they are located, not only by reducing our own consumption but also through direct interaction processes on the boundary conditions as environmental decontamination. In this way, we can create homes that become vectors of sustainability which in turn could lead to synergies in their environment. The property shown below has been designed by LAC-architecture and it is located in a peri-urban area of the city of Granada, with a mediterranean-continental climate in which there are alternating periods of temperaturas below zero with others which are above 40 º C. Due to these conditions, the materials and systems that control the inner housing conditions are subjected to a very wide range of actions. Attached to these systems, a photocatalytic cement based coating will be used and will be able to become a degradation source of the harmful organic and inorganic substances coming into contact with it. These substances are the NOX, SOX, NH3, CO, volatile organic compounds (VOCs), chlorinated organic compounds, aldehydes and aromatic polycondensation which are responsible for air pollution in our cities.

Oftentimes, the incorporation of ordinances and application of regulations of technical, social,or urban nature imply an appropriate study and analysis of the building, the population affected, their habits and any of the consequences caused by the resolution of new demands. The research developed by the team REPROGRAMA in the University of Seville, CONTRATO I+D, related to the field of action of the Consejería de Fomento y Vivienda of the Agencia de Obra Pública de la Junta de Andalucía, considers the needs of intervention in the Andalusian housing stock built between the 1940s-80s, in order to improve an active aging process, taking into account a gender perspective, comfort requirements, energy savings, and environmental sustainability. Considering the rehabilitation of the housing stock as one of the greatest challenges of today for cities and always considering the three pillars of sustainability, this research is to reflect upon the existing reality and to propose protocols of intervention, which would satisfy the social needs and meet the demands of the current regulations, improving the quality of life for the users and the protection of the environment. In this presentation we explain an important part of the research we’ve done, the management of the RCD generated in the construction of energetic rehabilitation from one particular case of great singularity—the neighborhood of Nuestra Señora del Carmen in the district of Los Remedios of Seville. In this case, the planned constructions will create a great amount of waste, which should be taken into consideration since it could be one of the facets that questions the viability of the intervention. We will show our proposal of the RCD management, including quantification, assessment, minimization, selection and treatment in situ, and the possibilities of use of the original building. We will offer the results obtained in relation to reusing and recycling the wastes to reincorporate them to the building, extending its lifespan as a “secondary material”, as part of the natural process in reformation projects and rehabitilitaion of buildings, in accordance with the Directive 2008/98/CE or the Plan Nacional Integrado de Residuos (National Integrated Plan of Wastes) 2008-2015.

Solar Decathlon Latin America and the Caribbean 2015 will take place in the city of Cali, Colombia. Coming from North America and after the European and Asian editions, now the competition for sustainable housing arrives Latin America. ‘Solar Decathlon’ is an international competition inviting students around the world from universities specialized in Engineering, Architecture, Urban Design, Renewable Energies and related careers to participate on creating, building and operating Self-sustaining social solutions, run by solar power. In addition to the founding principles of the original Solar Decathlon, the SD LAC2015 Organization has decided to focus on the following four components, which will be fundamental to the proposals in order to adapt them to tropical climate and cultural conditions. The components are: 1. Social Housing: As social inequality is one of the most pressing issues in Latin America and the Caribbean, the Solar Decathlon should strive to prove that sustainable housing based on alternative energy sources can be accessible to the population at large, prioritizing dense urban areas where most of the population is living. 2. Density: Nowadays, most of the population lives in cities where building areas are increasingly scarce and expensive. Moreover, denser housing solutions can help minimize the environmental impact. Consequently, the SD LAC2015 will favour projects that optimize the architectural and urban footprint. 3. Rational Use of Environmental Resources: The vast majority of the Latin American population lives in the tropics, enjoying high solar radiation all year long and exceptional availability of water sources. 4. Regional Relevance: The SD LAC2015 embraces the goal of developing and promoting ideas, capacities and technologies that can be implemented for the benefit of the inhabitants of the LAC region. The actual construction of prototypes will take place in the ‘Universidad del Valle’ campus. The competition combines both theoretical and practical knowledge considering projects must be built on real scale and be tested on 10 different contests. The hisCali team, from the Sevilla University, will take part in competition together with the ‘University of Santiago de Cali’, and with the support of the IUACC and the official masters of Innovation and Sustainability, both from the Sevilla University.
Energy efficiency and sustanibility on building through "intelligent" proccess
(Universidad de Sevilla. Escuela Técnica Superior de Arquitectura., 2015) Vascas Martín, J.; Mercader-Moyano, Pilar
The construction industry has recently developed new technologies to tackle the increasing complexity of today’s building facilities and systems. Therefore, the term “Intelligent Building” is becoming more often used to identify constructions that are able to integrate simultaneously coexisting systems and subsystems in a building. In addition we start using the term “Smart Building” implying further steps of system integration and interaction.
