The need for tools to achieve a higher level of competitiveness and profitability has made management systems an important partner for construction companies. The environment in which construction projects are developed is dynamic, mainly characterized by complexity, uncertainty, interdependence, nonlinearity, ambiguity and speed. This research adopted a deductive reasoning in two phases: Literature Review and Interviews. The first phase was focused on underlying the crucial current issues that impact on Construction Site Management and the relationships among Project Management, Construction Site Management, Systems Thinking and Complexity Theory. The second phase was carried out so that practitioners validated the research result. The result of this study is a conceptual framework of requirements, influencers and enablers to support General Contractors in developing their Project Management Systems.

Researchers have spent decades exploring strategies for reducing energy consumption in buildings worldwide, proposing passive solutions and optimizing active systems. However, no breakthrough technology has been developed. The use of thermoelectricity in buildings for heating, cooling and ventilation has been proposed as an alternative solution to many systems anchored in our day-to-day. This paper seeks to classify, analyze and summarize the possibilities of the thermoelectric technology integration in buildings. The results obtained from the search were divided into two main groups: systems that are integrated in the building envelope and non-integrated systems that operate independently. Among the analyzed parameters, on the one hand the characteristics of the prototypes' components needed for the construction were described. On the other, the thermoelectric specific parameters required for optimization under the operating scenarios' conditions were studied. The results of most of the studies showed that even though the technology can provide the comfort conditions, still the performance of these systems is not competitive compared to conventional vapor compression systems. However, the advantages of thermoelectricity such us the non-use of refrigerants or the high durability, makes this technology an alternative solution to consider, of which interest is growing in line with recent studies.

A Thermoelectric Cooling-Heating Unit (TCHU) is an innovative technology that uses the thermoelectric phenomena as a heating¿cooling system for buildings. In TCHU, a direct current (DC) electrical current supplies the power to a Thermoelectric Equipment (TE) heat-pump system, which can transfer heat in one direction or another depending on the current flow. The unit is integrated in the building envelope. At this stage of the study, a second prototype of TCHU has been developed using commercially available TE technologies. In this case, a vertical configuration of 16 TE modules is studied for their potential application as a heating and cooling system for residential buildings. Different nocturnal tests have been developed to evaluate the performance of the new system under real conditions and to determine the coefficient of performance for these TE modules when operating under different voltage regimes. It has been studied not only the cooling mode but also the heating mode. Based on the measured data, it has been demonstrated that the system can be successfully installed as a heating or cooling system in buildings. Tests have confirmed the huge relevance of the temperature difference between the two sides of the cells, taking especial relevance in the cooling mode. It has also been demonstrated that for the cooling mode it is better to work with low voltage values. Besides, some theoretical analyses have been developed in order to find out the most suitable configuration to obtain the best Coefficient of Performance (COP) of the unit in both cooling and heating.

Occupancy schedules in building spaces play an important role in evaluating a building¿s energy performance. This work seeks to identify disparities between different occupancy estimation techniques; standardised occupancy profiles found in literature, business processes¿ based profiles through interviews and accurate profiles from real on-field measurements. The occupancy diversity profiles of secondary spaces in a healthcare facility building are analysed through descriptive statistics and t test methods over different time horizons. Occupancy measurements are obtained by utilising a novel, robust and highly accurate real-time occupancy extraction system which is established through a network of depth cameras. Results indicate that the utilisation of real occupancy data, along with elaboration of the business processes that take place in building spaces have the potential to support more precise profiles in Building Performance Simulation software tools.

The use of Opaque Ventilated Façades (OVF) has considerably increased in recently years as an envelope solution in a variety of building types, climates, and design configurations. It is considered an appropriate solution not only for renovation of existing buildings but also for new buildings. The influence of ventilated façades in buildings is a constantly current issue in research always concluding the importance of the envelope in the reduction of energy needs in the whole building, and the importance of an accuracy model for the deep knowledge of the façade performance. Currently, the main interest in OVFs is their ability to reduce cooling thermal loads in Southern European locations. Although reference literature recognizes energy savings associated to the use of OVFs in comparison with traditional solutions, previous energy studies consider a limited number of locations and standard solutions. Trying to fill in an existing gap, this article includes information from different studies carried out in recent years which address the thermal and energy performance of OVFs. It also explains the implications of both external ambient conditions and design decision (external layer material, joints, air cavity width¿) in terms of the energy and thermal performance of OVFs. This paper also provides some key strategies for customizing the façade design according to specific climate conditions.

This paper is comprehended in the study of the application of the biomimicry science in building services and energy management, taking as a reference the case of tuna. Tuna generates heat in the muscles, organs and tissues of the inner area of its body (dark muscles). This heat is distributed in the periphery in order to maintain constant body temperature. From this biological reality, researchers analyse the possibility of altering the heating demand of an office on the basis of the heat conservation strategy applied by tuna, merely modifying the working-spaces. For this purpose, an existing office building with high architectonical quality parameters has been chosen and different scenarios have been defined in order to perform the energy simulations. The case studies correspond to the variations in the floor layout and occupancy density distribution. Besides, they are studied in three European cities with different climate. The evaluation of results is mainly focused on the heating demand since tuna strategy comprises the heat management. It is shown that the arrangement of high thermal load locals affects the heating demand of the building, being more efficient the tuna distribution in order to lower the demand.

In order to fulfil the current challenges for the European building sector, building design has diverged into two alternative directions: active technologies and passive design strategies. In the last few years, advanced and responsive building envelope components have represented a promising answer to these challenges. This paper presents the design and construction process of a project that aims to design, build and control the energy performance of an industrial-scale modular active ventilated facade prototype with a new Themoelectric Peltier System (TPS). The TPS is a thermoelectric HVAC heat pump system designed to be located in the building envelope and providing a high comfort level. Trying to optimize the energy performance of the traditional ventilated opaque facade, and make more efficient the energy performance of the TPS, the concept of adaptability has been applied to ventilated opaque facades. The essential research theme is to control the natural phenomena that take place inside the ventilated air cavity of the facade: taking advantage when heat dissipation is needed, and avoiding it when heat losses are not welcome. In order to quantify the previous statements, some facade prototypes are being built in Pamplona (Spain) and their energy performance is going to be analyzed during a year.

The research is looking for an innovative self-sufficient, industrialized and lightweight façade module that integrates a thermoelectric HVAC system. The principal aim of the research was to try providing a built answer to the current efficiency objectives (Directive 2010/31/CE), creating a façade solution that can be installed in new buildings or in already existing ones. This report tries to explain the theoretical design of this new façade system with Peltier cells.

The current methods of building energy simulation that designers and engineers (D&E) use in order to find the energy performance of a building do not take into account the real behavior of the people who will use the building. The main aim of this paper is to show how by merely including the real behavior of people in building simulations there may be differences of up to 30%, through the study of a real pilot site simulation with existing software. These data confirm the possibilities of energy and money saving that energy simulation programs bring about when they include schedules of true use of the building (BIM).

Con la oportuna efeméride del centenario del nacimiento de la Bauhaus se planteó un proyecto coordinado entre varias asignaturas para los alumnos de 2o curso del Grado en Diseño de la Escuela de Arquitectura de la Universidad de Navarra. Con el Ballet Triádico dirigido por Oskar Schlemmer en 1923 como referente principal, se proponía la elaboración de un evento performativo real, diseñado conjuntamente entre los cincuenta y tres alumnos que componían el curso y representado en el espacio de la propia Escuela. Un proyecto docente que daba la oportunidad de ensayar con los alumnos modos de trabajo colaborativo entre distintas disciplinas creativas y áreas del diseño, encontrar en el espacio fronterizo entre ellas caminos de innovación artística y experimentar con la propia Escuela de Arquitectura como espacio de interacción, intercambio y generación de ideas de proyecto.

"In the Department of Construction Science, we have developed and documented a specific model of systematized process in order to carry out activities of R&D&I oriented to a detailed design of constructive systems of innovative façades. This specific model will be used as a guide for the study, analysis, design and evaluation of the proposed solutions for façades. This model of systematized process of research provides a general idea of the set of stages and activities in the processes of R&D&I, with a graphical map and a documentary structure that describes how all the process works, step by step, facilitating its comprehension and application. The protocol details the key procedures within the global process. This protocol allows elaborating the programme of necessities derived from the conditionings, requirements and demands related to every specific façade, assisting with the definition of the technical characteristics of its parts and components to approach the conceptual and graphical design of constructive solutions, in successive stages. This protocol provides the means to analyze and evaluate every particular design of façade and the process of R&D&I that has been followed, so that it allows to justify and demonstrate the fulfilment of the requirements and demands that concern every stage of the complete life cycle of façades, and to identify fields that could be improved in the R&D&I process, in order to apply corrective actions. This protocol is complemented by som
