Validation of EnergyPlus thermal simulation of a double skin naturally and mechanically ventilated test cell

This paper presents a thermal simulation validation study of the typical precision that a trained thermal simulation engineer can expect to obtain for the simulation of a room connected to a naturally ventilated double skin facade. The open source building thermal simulation tool EnergyPlus is used to predict air and surface temperatures in a free running weather exposed test cell.

CFD modelling of double-skin façades with venetian blinds

This paper describes CFD modelling of Double Skin Façades (DSF) with venetian blinds inside the façade cavity. The 2-D modelling work investigates the coupled convective, conductive and radiative heat transfer through the DSF system. The angles of the venetian blind can be adjusted and a series of angles (0, 30, 45, 60 and 80 degrees) has been modelled. The modelling results are compared with the measurements from a section of façade tested within a solar simulator and with predictions from a component based nodal model. Agreement between the three methods is generally good.

A lumped model of double skin facade with cavity shading

A universal lumped model is developed with the aim to predict the thermal performance of Double Skin facade. Three modules – ventilation, heat transfer and penetration - are coupled to comprehensively describe the energy and mass transfer processes. The unknown parameters, resistance coefficient and heat convection coefficient, are discussed and estimated. The influences of cavity shading position, cavity depth and ventilation height on energy performances are analyzed at the end of the paper based on the simulation results.

Double skin façades – cavity and exterior openings dimensions for saving energy on Mediterranean climate

Taking into account Mediterranean climate particularities for Barcelona, Spain, a whole year study using TAS simulation software was carried out for a Double Skin Façade corporative office building. It is a typical office building with an extended working hours schedule for acclimatization.

Nowadays, the use of translucent or transparent façades as lining of another façade is increasing.

The climatic potential for a double skin facade integrated with cross ventilation

When it comes to natural ventilation performance for large space cooling during summer time or intermediate seasons, double skin facade(DSF) integrated with cross ventilation(CV) exhibits more energy efficiency than single-side ventilated DSF. In this case, ventilation performance is remarkably affected by climatic conditions. Therefore, it is important to analyze micro climatic conditions before applying this passive technique.

Analysis of Reduced Cooling Load for a Multistorey-Building Incorporating a Ventilated Double Skin Façade with a Solar Chimney Channel

A double skin façade (DSF) aims at reducing heating and cooling loads by taking advantage of daylight and utilizing heated air for space heating. To take advantage of a DSF a sophisticated design is required. In this paper a DSF building that has overheating problems was selected to verify the causes and propose remedial solutions. The problem was verified by analyzing the measured solar radiation, inside and outside temperature and air velocity. The results of the measurement analysis showed that airflow congestion caused overheating inside the building.

Best Practice Guidelines for Double Skin Facades

Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climateis, however, being questioned. Therefore more and more of these buildings are being built with doubleskin facades, which can provide: a thermal buffer zone, energy savings, wind protection with openwindows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, pollutantprotection with open windows, nocturnal cooling and a site for incorporation of PV cells.

Best Practice for Double Skin Facades The BESTFACADE Project

Double skin facades have become a major architectural element in office buildings over the last 15years. A double skin facade can provide a thermal buffer zone, solar preheating of ventilation air,energy savings, sound protection, wind and pollutant protection with open windows and nocturnalcooling. Commercial buildings with integrated double skin facade can be very energy efficientbuildings with all the good qualities listed above.However not all double skin facades built in the last years perform well.

Double-Skin Facade with Venetian Blind: Global Modelling and Assessment of Energy Performance

In this past decade, glazed façades use in new buildings has soared. Some of these façades, called "double skin façades", are made of internal and external glazing. As indicated by its name, "double skin façades" are a special type of envelope which air s
