Abstract(s)
Tendo em conta que a construção dos edifícios muitas das vezes implicam gastos excessivos de energia bem como perdas da mesma, sentiu-se a necessidade de contribuir com este estudo para a edução energética e preservação ambiental. Assim, este trabalho foi elaborado numa câmara climática situada no parque de estacionamento da Faculdade de Engenharia da Universidade da Beira Interior. Para tal, recorreu-se aos modos de transmissão de calor – condução, convecção e radiação – em elementos construtivos (uma parede de viroc e uma parede de viroc, cortiça e plantas com substrato). Por este meio, calculou-se experimentalmente os coeficientes globais e convectivos de transmissão de calor, verificando-se que a parede de viroc, cortiça e plantas com substrato (câmara climática 2) é mais eficiente energeticamente do que a parede apenas de viroc (câmara climática 1). Pelo exposto, atingiram-se os objetivos propostos, uma vez que se conclui ser possível reduzir energeticamente o consumo dos edifícios e assim contribuir para a preservação ambiental.
Considering that, in the building construction, are implied an excessive expenses in energy and their losses. It felt the necessity to contribute with this work for a better energy education and environmental preservation. This work was made in a climatic chamber located in the parking lot of the Faculdade de Engenharia of the Universidade da Beira Interior. To this end, we resorted to modes of heat transfer - conduction, convection and radiation - in constructive elements (one wall of viroc and a wall of viroc, cork and plants with substrate). By this means, it was estimated experimentally the global and convective heat transfer coefficients, it has been found that the wall viroc, cork and plants substrate (climatic chamber, 2) is more energy efficient than the wall only viroc (chamber climate 1). Aforementioned, it is reached the proposed objectives, since it can be concluded reduce the energy consumption of buildings, thus contributing to environmental preservation.
