The provision of proper indoor thermal conditions in winter is a requirement for health and comfort that is seriously compromised in Southern European countries by poverty and inadequate housing. According to Eurostat (EU-SILC, 2016), 10.1% of the population in Spain state they are "unable to keep their home adequately warm" in winter, unveiling one of the critical consequences of energy poverty. Although relevant field monitoring assessment have been conducted in other European countries, very little research has been carried out in the context of Spain. In this study we collected winter indoor temperature data, socio-economic, building and heating system characteristics from 112 multi-family dwellings in social housing built in the 40-80s in the North of Spain. The main building determinants of temperature variation were examined and assessed according to the socioeconomic situation through a mediation analysis. The principal findings showed that households living within district heating networks maintained temperatures above 18 degrees C on a continuous basis, whereas 54% of households living outside these heating networks presented temperatures below this threshold during night periods in bedrooms, while 25% had temperatures below 18 degrees C during both day-time and night-time occupied periods. Within this 25% of cold homes, 16.4% corresponded to households under the poverty threshold. As the mediation analyses showed, poorer households in the sample were associated with lower temperatures and higher temperature contrast throughout their dwellings for the following reasons: a lower incidence of vulnerable cases within district heating networks, heating restriction behaviours, higher dependency on room-heaters, lack of central heating and more thermally inefficient dwellings. The evidence presented in this paper offers a new framework for comparing the assumptions derived from other contexts to the situation in Spain about the effects of space heating and housing deprivation on thermal conditions, provides a basis for reviewing some possible intervention, and aims to raise social and political awareness further about this issue.

Since the origin of the Modern Movement, there has been a basic commitment to improving housing conditions and the well-being of occupants, especially given the prediction that 2/3 of humanity will reside in cities by 2050. Moreover, a compact model of the city with tall buildings and urban densification at this scale will be generated. Continuous constructive and technological advances have developed solid foundations on safety, energy efficiency, habitability, and sustainability in housing design. However, studies on improving the quality of life in these areas continue to be a challenge for architects and engineers. This paper seeks to contribute health-related information to the study of residential design, specifically the influence of the geomagnetic field on its occupants. After compiling information on the effects of geomagnetic fields from different medical studies over 23 years, a case study of a 16-story high-rise building is presented, with the goal of proposing architectural design recommendations for long-term occupation in the same place. The purpose of the present work is three-fold: first, to characterize the geomagnetic field variability of buildings; second, to identify the causes and possible related mechanisms; and third, to define architectural criteria on the arrangement of uses and constructive elements for housing.

Buildings today represent 40% of world primary energy consumption and 24% of greenhouse gas emissions. In our society there is growing interest in knowing precisely when and how energy consumption occurs. This means that consumption measurement and verification plans are well-advanced. International agencies such as Efficiency Valuation Organization (EVO) and International Performance Measurement and Verification Protocol (IPMVP) have developed methodologies to quantify savings. This paper presents a methodology to accurately perform automated envelope calibration under option D (calibrated simulation) of IPMVP ¿ vol. 1. This is frequently ignored because of its complexity, despite being more flexible and accurate in assessing the energy performance of a building. A detailed baseline energy model is used, and by means of a metaheuristic technique achieves a highly reliable and accurate Building Energy Simulation (BES) model suitable for detailed analysis of saving strategies. In order to find this BES model a Genetic Algorithm (NSGA-II) is used, together with a highly efficient engine to stimulate the objective, thus permitting rapid achievement of the goal. The result is a BES model that broadly captures the heat dynamic behaviour of the building. The model amply fulfils the parameters demanded by ASHRAE and EVO under option D.

This research shows the study and analysis of sunspaces behaviour as passive elements of architecture during the summer, taking into account that they are fundamentally passive solar heating elements for winter. This study is carried out through monitoring and energy simulation of six case studies, applying it to summer 2011¿2012 which was extremely hot for the climate zone in which it is located. These results are useful for the study of residential buildings with the forecasts of climate change for Pamplona, especially for an architectural element as sensitive to overheating as is an attached sunspace. The research concludes that attached sunspaces also have a good thermal behavior in summer, even in extreme conditions, as long as they are designed and used properly, and therefore no active cooling system is necessary. This research also explores the energy efficiency and optimized design of the sunspaces for different climate zones in Spain, selected attending mainly to the severity of summer although with different winter conditions.

This investigation deals with the thermal performance of two passive solar components. An attached sunspace with horizontal heat storage and another one with vertical thermal storage were designed in order to optimize the use of solar gain, its storage and distribution in an industrialized component. These sunspaces have been tested under real conditions, comparing their thermal performance with two commonly used components in residential buildings in Spain: a window and a double window making up an attached sunspace. Different series of experimental measurements were made in two test-cells exposed to outdoor conditions in Pamplona (Northern Spain). As a result, nine scenarios during winter 2011 and six ones during summer 2012 have been carried out, comparing all the prototypes two by two with different use modes. Resu**lts show that a sunspace with heat storage takes advantage of the solar energy and improves the indoor thermal performance of the adjacent room during winter in a better way than a window or a simple sunspace, and that it has also a better performance in summer. The best results in winter and summer were obtained when an appropriate use of the component is performed, in concordance with outdoor conditions; some thermal control actions for the good performance of these components are suggested.

Este libro recoge las tipologías de fachadas, los principales componentes que se pueden emplear en cada una de ellas y los puntos singulares, para que sirvan para una adecuada definición y resolución constructiva. Se ESTRUCTURA en ocho capítulos. En el primero se exponen las exigencias que deben cumplir las fachadas de los edificios y los criterios de diseño de estos cerramientos. Los capítulos segundo, tercero y cuarto recogen las diferentes tipologías de fachadas: la fachada tradicional, la fachada industrializada opaca y la fachada de materiales traslúcidos, respectivamente. En el quinto capítulo se presentan las carpinterías exteriores y en el sexto, los sistemas de protección solar y visual. Todos estos apartados siguen un esquema similar: en primer lugar, se describe el comportamiento de la tipología correspondiente, en segundo lugar, los distintos componentes y soluciones constructivas, y, a continuación, se presenta la resolución de los puntos singulares. En el capítulo séptimo se muestran directrices para la elaboración del proyecto de fachada mediante fichas de autocontrol que pueden servir para la definición de los distintos documentos que lo componen. El último capítulo, dedicado a la Patología y Rehabilitación de Fachadas, pretende analizar los problemas que pueden surgir, para evitarlos o para llegar a la reparación adecuada.

  OTROS MÉRITOS RELEVANTES

Professor of University (since 1993). I am currently the vice-dean of research and teaching at the School of Architecture of the University of Navarra (ETSAUN), where I also direct the Master's Degree in Environmental Design and Management of Buildings (MDGAE). Since I finished my degree in 1986, I have dedicated myself to teaching, research and freelance practice of the profession. I have carried out 46 new construction works and 66 rehabilitation works. As a professor, I currently teach in the degree of Architecture the subjects of Construction I (Roofs) and Construction II (Facades); in postgraduate course in the Master MDGAE: Principles of sustainability, Energy management, passive measures and environmental certification. As a researcher, I lead the SAVIArquitectura group, and my topics of interest are ecodesign of industrialized and sustainable enclosures, the energy rehabilitation of buildings and neighborhoods, and the quantification of sustainable architecture. I have extensive research experience in these fields having participated in 28 projects, agreements and research contracts. The books (17) and articles (37) published are the result of this investigation. My research activity begins with the development of my doctoral thesis that dealt with "REHABILITATION OF BUILDINGS. APPLICATION OF INDUSTRIALIZED TECHNIQUES "that ended in 1993, whose purpose was to study industrialized techniques for the energy rehabilitation of the enclosures. This thesis can be considered a pioneer in this field given the great current application of this type of systems. In the following years I have continued researching in the field of new technologies for the design of sustainable enclosures, for their application in new construction and rehabilitation. In the first case, highlights the project INDUSTRIALIZATION OF LOW COST BIOCLIMATIC HOUSING (2007-2012), which has resulted in the publication of a book, an article in the magazine Energy and Buildings (Q1) and a patent in operation, as well as as a doctoral thesis. In the second, the project PROTOCOL OF ACTION IN THE REHABILITATION OF THE ENVELOPE OF BUILDINGS BASED ON THE BENEFICIAL DESIGN (2013-2015), which gave rise to another doctoral thesis and another in execution, which has been disseminated in conferences and there are currently other several articles in preparation. I also participate in the European SABINA project that develops technology capable of maximizing the integration of renewable energies in buildings and the accumulation of energy in the enclosures themselves. My concern for sustainable architecture was channeled with these and with other research projects such as, among others, the GUIDES FOR SUSTAINABLE BUILDING IN THE COMMUNITY OF THE BASQUE COUNTRY, 2009 and COST EFFECTIVE ENERGY AND CARBON EMISSIONS OPTIMIZATION IN BUILDING RENOVATION, Annex 56 International Energy Agency (IEA) 2015. They are also a testament of my experience and my interest in the energy rehabilitation of buildings and neighborhoods, the ENERGY AND SOCIAL MODEL projects, WITH GIS TOOL, FOR AN EFFICIENT REHABILITATION IN PAMPLONA, and the participation in Annex 75 of the IEA (COST-EFFECTIVE BUILDING RENOVATION AT DISTRICT LEVEL COMBINING ENERGY EFFICIENCY & RENEWABLES). I have been a visiting researcher at the following Universities: Welsh School of Architecture (UK, 2013 and 2014), at the Worcester Polytechnic Institute (USA, 2013, 2015, 2017), and at the Masachussetts Institute of Technology (USA, 201
