This work is a TRNSYS simulation of solar thermal system working together with an existing small sized CHCP (Combinet Heat Cooling and Power) demonstration project, included in the workpackage 5 (simulation) of the PolySMART project. The first objective of this work is to fine tune simulation parameters of the simulation Units (or Types), based on monitoring data collected during the first semester of 2010. The...
The goal of this work was to clarify the macrostructural changes that take place upon sintering of open cell cordierite based foams. A methodology, based on optical image analysis, was developed to assess the structure of open-cell foams, which allowed evaluating the macrostructure of both cordierite based foams obtained by the replication process and their polymeric templates. The parameters used to describe t...
This paper presents first results of a project that aims at the development of new mathematical models for characterization of Solar Thermal Systems (Factory Made Systems as defined in EN 12976) that can be used in association with dynamic system testing (non intrusive test method defined in the document ISO 9459-5) and which, based on the characteristic parameters defined in the adopted models, allow determina...
In this paper the authors intend to share the lessons learned in the designing process of a solar office building currently underway to reach the Net Zero-Energy performance. Solar XXI building was built in Lisbon in 2006 as a demonstration project [1]. The building, which design is based on a combination of passive design techniques with renewable energy technologies (PV, solar collectors), may be currently co...
O Museu municipal de História Natural de Sintra, em curso de instalação, tem por base as colecções de fósseis e minerais reunidas pelo pintor e escritor Miguel Barbosa e esposa. Tendo em consideração as características deste acervo e o previsível universo de utentes, tem vindo a ser esboçado um programa cultural e científico essencialmente dirigido para a divulgação e o ensino (informal) das Ciências da Terra.
O acervo paleontológico reunido por Miguel Barbosa ao longo de anos de colheitas, permutas e compras, perfaz um total de cerca de 7 000 exemplares, entretanto cedidos pelo coleccionador à Câmara Municipal de Sintra. Constituindo o embrião das colecções do futuro Museu (municipal) de História Natural, este acervo tem vindo a ser objecto de identificação, catalogação e organização tendo em vista a sua pública dis...
