“…O modelo reduzido apresentava apenas uma entrada de ventilação, aliada a baixa velocidade do vento registrada no interior dos ambientes (0,38 m s -1 ) o que propiciou a redução das transferências de calor por convecção. Havendo pouca troca de ar entre o interior e o exterior, a energia proporcionada pela incidência da radiação solar faz aumentar a temperatura interna e a massa de ar quente não é dissipada pelas correntes laterais e ascendentes, o que evidenciou o efeito do incremento térmico proporcionado pela transmissão de energia das coberturas (Faggianelli et al, 2014). A redução da temperatura do ar nos abrigos com telhado verde (Tame e Tgra) comparativamente com Tfib foi de 0,65 e 0,67 o C, respectivamente.…”

RESUMOObjetivou-se, com este trabalho, avaliar o conforto térmico proporcionado por diferentes tipos de cobertura, com base nas análises térmicas e nos índices de conforto térmico humano e zootécnico. A pesquisa foi realizada no período de 20 de março a 29 de maio de 2014, na UFRPE, no município de Recife, PE. Os tipos de cobertura analisados foram: telha de fibrocimento (Tfib), telha reciclada (Trec), telhado verde, grama, Zoysia japonica (Tgra) e telhado verde, amendoim, Arachis repens (Tame), com quatro repetições cada um; as variáveis meteorológicas foram registradas interna e externamente aos modelos. A análise térmica das coberturas foi realizada por meio de imagens termográficas e o conforto térmico das instalações foi obtido por meio dos índices de conforto, carga térmica radiante, índice de temperatura de globo negro e umidade, índice de conforto humano, índice de temperatura e umidade e temperatura efetiva. Os telhados verdes (Tame; Tgra) reduziram a temperatura da superfície interna das coberturas (5,3 e 4,4 ºC), promoveram maior atenuação da temperatura dos ambientes (1,37 e 1,35 ºC) e, consequentemente, promoveram também maior conforto térmico, em comparação com a Tfib e Trec.

“…This made it possible to analyse how the potential use of climate factors is greatly conditioned by the shape of buildings and the pre-existing urban layout (Vermeulen, 2015). As observed in the French research project VALERIE (Chesné, 2012), energy consumption in buildings can be greatly reduced if good use is made of the resources of the environment (Antone Faggianelli, 2014). However, building environments are not the sole factor affecting energy consumption.…”

In order to minimise the environmental problems of energy consumption this study aims to assess the potential energy demand reduction of the three main building types within three urban configurations of a Mediterranean city in the Comunitat Valenciana Region, Spain. To do so this project aims to identify the urban configuration which makes the best use of sun and natural ventilation, and whether this potentially affects the energy consumption of users in three vulnerable neighbourhoods as an analysis methodology prior to any intervention on the building stock. Factor analysis was carried out in summer taking into account the greater influence of the climate factors in the warm region under study. Therefore, winter conditions were excluded from this analysis as the installations, and the state of conservation of the envelope were the main factors affecting the energy consumption at this time of year. The results obtained show that there is true potential for reducing consumption in the buildings analysed. Due to the viability and easy implementation of these actions, and given the embodied energy, the measures for optimising the envelope of buildings are inadvisable or to be considered only as a last resort.

“…At night, ventilation cools down the thermal mass, avoiding heat release during the day and therefore limiting over-utilisation of artificial cooling. Faggianelli et al [33] investigated the use of thermal breezes to improve natural ventilation in houses located on the Mediterranean coast. To avoid complex modelling, the authors used a statistical wind rose supported by tracer gas measurements to investigate the implication of breezes in natural cross-ventilation flow rates.…”

Tropical coastal areas are characterised by high levels of wind and solar resources with large potentials to be utilised for low-energy building design. This paper presents a multi-objective optimisation framework capable of evaluating cost-efficient and low-exergy coastal building designs considering the influence of the thermal breeze. An integrated dynamic simulation tool has been enhanced to consider the impacts of the sea-land breeze effect, aiming at potentiating natural cross-ventilation to improve occupant's thermal comfort and reduce cooling energy demand. Furthermore, the technological database considers a wide range of active and passive energy conservation measures. As a case study, a two-storey/two-flat detached social house located in the North-Pacific coast of Mexico has been investigated. The optimisation problem has considered the minimisation of: i. annual exergy consumption, ii. life cycle cost, and iii. thermal discomfort. Optimisation results have shown that adequate building orientation and window opening control to optimise the effects of the thermal breeze, combined with other passive and active strategies such as solar shading devices, an improved envelope's physical characteristics, and solar assisted air source heat pumps have provided the best performance under a limited budget. Compared to the baseline design, the closest to utopia design has increased thermal comfort by 93.8% and reduced exergy consumption by 10.3% whilst increasing the life cycle cost over the next 50 years by 18.5% (from US$39,864 to US$47,246). The importance of renewable generation incentives is further discussed as a counter effect measure for capital cost increase as well as unlocking currently high-cost low-exergy technologies.
