“…Scientific literature about OJVFs is very scarce, although there are some papers analysing certain characteristics also applicable to these façades, for example, studies evaluating different panel materials (ceramic [56], clay, stone [57], or even metal [58,59]) or the effect of the climate [60]. There are some articles considering the influence of the geometry, although they do not provide specific data [61,62].…”

Commercial and residential building is one of the four major final energy consumption and end-use sectors. In this sector, cooling loads represent an important part of the energy consumption, and therefore, they must be minimized, improving the energy efficiency of buildings. Ventilated façades are one of the most widely used passive elements that are integrated into buildings, precisely with the aim of reducing these loads. This reduction is due to the airflow induced in the air cavity by the buoyancy forces, when the solar radiation heats the outer layer of the façade. In the open joint ventilated facades (OJVF), ventilation is attained through the open joints between the panels composing the outer layer. Despite the steadily growing research in the characterization of this type of system, few studies combine the numerical modelling of OJVF with experimental results for the assessment of the airflow in the ventilated cavities. This paper experimentally validates a numerical simulation model of an OJVF. Firstly, the façade performance has been experimentally assessed in a laboratory model determining the temperatures in the panels and air gap and measuring the flow field at the gap using particle image velocimetry (PIV) techniques. Secondly, a numerical model has been developed using advanced Computational Fluid Dynamics (CFD) simulation tools. Finally, an experimental validation of the numerical model has been done. Experimental and numerical results are compared in different planes inside the ventilated cavity. The discrete ordinates (DO) radiation model and the k-ε renormalisation group (RNG) turbulence model better adjust the simulated results to the experimental ones.

“…Many researchers have verified and validated the EnergyPlus engine and DesignBuilder software, such as studies reported by Blanco et al [39], Zhuang et al [40], Anđelković et al [41], Alam et al [42], Fernando Garsia et al [43], and Shehadi [44]. However, to be assured of the reliability of our findings, a single zone building located in Melbourne, Australia, as presented by Alam et al, was selected for validation.…”

Modeling Nearly Zero Energy Buildings for Sustainable Development in Rural Areas

et al. 2020

The energy performance of buildings and energy-saving measures have been widely investigated in recent years. However, little attention has been paid to buildings located in rural areas. The aim of this study is to assess the energy performance of two-story residential buildings located in the mountainous village of Palangan in Iran and to evaluate the impact of multiple parameters, namely building orientation, window-to-wall ratio (WWR), glazing type, shading devices, and insulation, on its energy performance. To attain a nearly zero energy building design in rural areas, the building is equipped with photovoltaic modules. The proposed building design is then economically evaluated to ensure its viability. The findings indicate that an energy saving of 29% can be achieved compared to conventional buildings, and over 22 MWh of electricity can be produced on an annual basis. The payback period is assessed at 21.7 years. However, energy subsidies are projected to be eliminated in the near future, which in turn may reduce the payback period.

“…Apesar de a maioria dos estudos dedicados às fachadas duplas terem foco o uso do vidro como material para a segunda camada, outros materiais têm sido recentemente considerados para o projeto da segunda pele como, por exemplo: membrana têxtil (PAECH, 2016); a membrana de PVC (ZHANG et al, 2016); chapa metálica perfurada (BLANCO et al, 2016); tela reticulada de cabos de aço inox (AECWEB, 2017); vergalhão de aço (ARCHDAILY, 2014); painéis de concreto polímero (ULMA, 2017); e a madeira (STAZI et al, 2014).…”

Atualmente, o mercado possibilita uma variedade de elementos e configurações de fachadas, variando em materiais, orientação solar, tamanho de janelas, tipo de vidro e, consequentemente, no orçamento. Dentre as configurações possíveis de fachadas, uma que vem se destacando em projetos de edifícios, tornando-se um importante elemento arquitetônico, que aproveita sistemas solares passivos, é a Fachada Dupla, um sistema muito utilizado em climas mais frios como na Europa e, principalmente, na Alemanha. Esta pesquisa é parte dos resultados de uma dissertação de mestrado e teve como objetivo caracterizar como essas fachadas duplas estão sendo inseridas no clima brasileiro, e os tipos de materiais que estão sendo aplicados nesta segunda pele da fachada. O estudo qualitativo utilizou como metodologia estudos de casos múltiplos e levantamento bibliográfico para identificação dos materiais que estão sendo aplicados como segunda pele para o projeto dessas fachadas no Brasil. Os resultados mostraram que, no Brasil, além da utilização da fachada dupla de vidro, outros seis tipos diferentes de materiais têm sido usados nessa segunda pele em edifícios, sendo elas: chapa metálica, membrana têxtil, madeira, concreto polímero, vergalhão de aço e os cabos de aço inox.
