A parametric study of the energy performance of double-skin façades in climatic conditions of Crete, Greece

Abstract The article deals with the issue of double skin transparent facades as a new technological-operational system of transparent exterior walls. Especially of high-rise buildings, which with its operating modes ingeniously uses a renewable source of solar energy to reduce the energy needs of the building. The basic precondition for the correct function of the double skin facade is its functional aerodynamics in any climatic conditions of the outdoor climate. In the critical state of windlessness, the aerodynamic quantification of a double skin facade is the total aerodynamic resistance of the cavity, which consists of the aerodynamic frictional resistances along the length of the air flow line and local aerodynamic resistances of the cavity. The article analyses the functional aerodynamics on two frequented types of double skin facades with a narrow type and corridor type cavity. At the end it confronts functional aerodynamics with the results of their temperature, aerodynamic and energy regime obtained from in-situ experiments.

Currently, insulated glass units (hereinafter abbreviated as IGU) are the main type of translucent filling used in curtain walls. Under the influence of climatic loads in IGU, the thickness of the inter-glass space changes, leading to the deformation of the glasses. Deformations of glass lead to optical distortions on curtain walls. The paper considers the technical solutions used in the existing engineering practice to reduce the distorting curvature of IGU: the use of more rigid external glasses as part of IGU, the use of double-skin facades with external independent single glass, the use of vacuum IGUs. A new method is proposed to reduce the distorting curvature of IGUs by fixing the thickness of the interglass space. It is achieved by installing other point or linear supports between the panes. The introduction of other supports solves the problem of reducing deformations only when IGU is compressed. When the interglass space is expanded, the supports are turned off from operation and the glass is freely deformed. Therefore, to avoid such deflections, it is necessary to pre-compress the IGU under a load equivalent to the climatic load on the IGUs operating in the construction area of the object. Calculations show that for the climatic conditions of the city of Moscow, the required degree of rarefaction the interglass spaces is only 5 % of the absolute atmospheric pressure.

This paper examines the possibilities of improving the energy performance of an existing industrial building by application of the double skin fa?ade on the revitalization of the building envelope in the climatic conditions of the city Novi Pazar, Republic of Serbia. The aim is to examine the impact of choosing the type of glazing, in the processes of revitalization, on the energy needs of industrial buildings for heating and cooling, as well as the contribution of the measures implemented to improve the energy performance of the selected type and model of industrial building. The energy performance of buildings was obtained using the software DesignBuilder and EnergyPlus simulation platform, taking into account the parameters of required internal temperature and climate data for the Republic of Serbia. The comparative analysis of the results of energy simulation according to the criterion of achieving greater energy savings and reduced carbon dioxide emissions was performed. The methodological approach in this research involves creating revitalization scenarios of industrial buildings with a shed roof construction, selection of the specific building according to whose properties by numerical simulation possibilities for energy revitalization depletion were investigated and comparative analysis of the obtained results was performed. The primary objective of this research is to investigate the impact of choosing the type of glazing on the energy performance of industrial buildings with a shed roof construction and to determine the optimal approach to energy revitalization of existing industrial buildings with the implementation of the double skin fa?ade under the climatic conditions of the city Novi Pazar, Republic of Serbia. The results of this paper indicate the negative characteristics of the kopilit glass to solar gains, whose retention requires a large amount of heating energy. While replacing of kopilit glass with a low-energy glass increases the amount of energy required to cooling of the building. With this research, through various revitalization scenarios, it is also indicated that using a double skin fa?ade in the revitalization process of the selected building, has a very similar impact on reducing CO2 emissions regardless of the type of glazing choice.

Two Envelopes

Estimating thermal effect of so called double-skin fa?ades on energy performance of buildings with two envelopes, a proprietary mathematical model of heat transfer through double-skin fa?ades has been developed. A very specific approach of the mathematical model presented here is based on prediction of the double-skin fa?ades interspace temperature and assumption that fa?ade could be treated as a single one declaring the interspace temperature and reduced intensity of solar radiation as the ?outdoor? conditions. In this paper results of the heating and cooling loads as well as the interspace temperature prediction compared for three months (January, April and July) and for the west oriented fa?ade with ordinary and absorption glass are presented. Fa?ade is placed under climatic conditions of Belgrade (45? North Latitude). Also, results for weather conditions of sunny and cloudy day are shown. Results includes influence of air velocity in interspace of fa?ades for April and July. Following a type of the double-skin fa?ade construction assumption it was implied that the space between the two envelopes is closed during the winter mode for air circulation, in order to have temperature higher inside than outside and opposite in the summer mode, air inlet and outlet are opened in order to prevent much higher temperatures than the outside ones, and higher cooling load of an air-conditioned building, as a consequence. Taking only thermal effects into account, presented prediction has proven that double-skin fa?ades decrease both building heat losses and heat gains throughout the year, and give significant contribution to the building energy consumption savings.
