Face aos padrões atuais de vida, em que despendemos a maior parte do nosso tempo no interior de edifícios, com um nível de conforto que ninguém quer abdicar, urge o desenvolvimento de tecnologias de climatização sustentáveis. Devido a uma combinação única de fatores, casas de baixo consumo de energia (e também casas passivas) em Portugal, são particularmente adequadas de explorar as vantagens da energia solar térmica, especialmente quando combinado com armazenamento sazonal de energia. No entanto nenhum exemplo documentado existe de como esta sinergia pode ser explorada com sucesso em Portugal, ilustrando assim o modo em que a necessidade de aquecimento pode ser colmatada de uma forma sustentável sem o uso de combustíveis fósseis. A energia solar é uma excelente alternativa de fonte de energia para aquecimento de edifícios. Um principal fator que limita a sua aplicação é que é uma fonte de energia com uma disponibilidade média de variação cíclica. O uso de armazenamento sazonal de energia pode reduzir substancialmente o custo do sistema solar que é capaz de fornecer até 100% das necessidades energéticas dos edifícios. Estes sistemas são projetados para armazenar a energia solar durante o verão e reter o calor armazenado para posterior utilização durante o inverno; Abstract: SEASONAL SOLAR THERMAL ENERGY STORAGE FOR LOW TEMPERATURE HEATING BUILDINGS. Given the current standards of living, where we spent most of our time inside buildings, with a level of Comfort that no one wants to give up, urges the development of sustainable climate control technologies. Due to a unique combination of factors, low energy (and also passive) houses in Portugal are particularly well suited to exploiting the advantages of solar thermal energy especially when combined with seasonal energy storage. However no documented example there of how this synergy can be exploited successfully in Portugal, illustrating the way in which the need for heating can be addressed in a sustainable manner without the use of fossil fuels. Solar energy is an important alternative energy source for heating applications. One main factor that limits its application is that it is an energy source with an average availability of cyclical variation. The use of seasonal thermal energy storage can substantially reduce the cost of solar energy systems that can supply up to 100% of buildings energy needs. Such systems are designed to collect solar energy during the summer and retain the stored heat for use during the winter.

The main aim of this chapter is to analyze the social and political effects of dynastic marriages between the Portuguese and Castilian-Aragonese crowns on the configuration of transnational, aristocratic families during the sixteenth and seventeenth centuries. To illustrate these questions we have chosen to follow the Soares de Alarcão family (known in Spain as Suárez de Alarcón) and the paths it took between the royal houses of Portugal and Castile for seven generations. The working hypothesis of the chapter is that the identity of the Iberian nobility during this era was characterized by a shared noble culture rather than by any particular features derived from the family’s land of origin. That assumption allows us to discuss whether the use of a particular language or culture indicates ties or political loyalties based on criteria of nationality, or, at the very least, place of birth. Therefore, this essay discusses the miscegenation of Iberian nobilities derived from dynastic marriages. It articulates the structural characteristics of this group and its political impact with the individual trajectories and historical contexts in which they developed. While these topics can be of interest for the comprehension of Portuguese early modern history, they can also help us to reflect more broadly on processes of identity construction.
