自由呼吸,双层玻璃幕墙

近年来,建筑物的节能舒适理念深入人心。作为影响室内热舒适度和建筑能耗的重要因素和关键部位,建筑外墙设计在技术、工艺、安装等方面都有重大突破和发展。由于反射玻璃幕墙造成的太阳光反射和光干扰性污染.通透的全玻璃幕墙系统被广泛使用,然而这种幕墙有一个极大的缺点——太阳强紫外线幅射和太阳热幅射透过大清玻璃进入室内,使室内温度大大升高。在这种背景下,出现了一种兼具通透性与防止太阳强幅射功能具有较高的节能效果的幕墙——呼吸式双层玻璃幕墙。

Thermal behaviour of a ventilated double skin facade in hot arid climate

Modern Movement in architecture has resulted in a large number of high-rise buildings with glazed facades which increase the energy load of the buildings. To combat this phenomenon in colder climates, architects have turned to using double skin facades. These facades comprise of: a completely transparent external facade; an internal skin; and an air layer between the two. Research on the performance of double skin facades mostly considers cold and moderate climates. In addition, data collection is normally based on simulations, rather than actual field measurements. In this paper a building with double skin facade was monitored for 2 weeks in summer and 2 weeks in winter in the hot arid climate of Iran, in order to observe the behaviour of the facade both in hot and cold conditions. Additionally, simulations were performed on the case study building with and without double skin facade, to assess the effectiveness of the facade. The results revealed that the temperature difference between the outer skin, the inner skin and the cavity can significantly save heating energy in winter. To reduce the cooling loads in summer it is essential to introduce additional techniques such as night ventilation and installation of shading devices for the cavity.

Feasibility analysis of an active technology to improve acoustic comfort in buildings

In buildings, windows and glazed facades are often the preferred noise path for exterior disturbing noise towards the interior. Since passive means for improving sound transmission loss (STL) of glazed facades are very expensive and are effective only at high frequencies, an active controller that increases the STL in the low-frequency range is an attractive approach for reducing the noise level in buildings with glazed facades, guaranteeing the performance required by the 89/106/CEE European Directive, which made protection against noise a compulsory requirement for buildings. As buildings are often inserted in highly inhabited urban areas, near infrastructures and plants radiating high noise levels, the strategic importance of this task is increasing, together with the importance of acoustic comfort inside buildings.

Effects of double glazed facade on energy consumption,thermal comfort and condensation for a typical office building in Singapore

Fully glazed facade that has been increasingly used in Singapore causes higher energy consumption and thermal discomfort due to higher solar gain. The use of double glazed facade system with ventilation system is one way to solve these problems. The objective of this paper is to investigate the effects of double glazed facade with ventilation system on the energy consumption, thermal comfort and condensation and compare to single glazed facade system. TAS and CFD software were utilized to calculate energy consumption, thermal comfort and condensation for single glazed facade building as well as double glazed facade building. The simulation results showed double glazed facade with natural ventilation were able to minimize energy consumption as well as to enhance the thermal comfort. Turning the mechanical fans on could also solve the condensation problem due to high humidity.     

Experimental determination of thermal performance of glazed façades with water film,under direct solar radiation in the tropics

An experimental investigation of a glazed façade oriented west has been conducted utilizing the Sustainable Glazed Water Film (SGWF). The experiments involved the following three parameters namely: the water flow rate, the type of glazing, and the solar radiation intensity. Two full-scale rooms were used, one as a reference room, with a fixed configuration, and the other as a test room, which could be configured in different ways. The ability of the SGWF to reduce the passage of the solar energy during the sunny hours and hence to limit the heat passage through glazing was analyzed. The aim of this paper is to examine the improvement in thermal performance obtained by the flowing water film over glazed façades. It has been found that the flowing water film on the glazed façade lowers the glazing surface temperature by 7.2–14 °C (average) and absorbs a portion of the solar energy resulting in decreasing indoor temperature by 2.2–4.1 °C (average). However, with increased solar radiation intensity, the SGWF provides a better level of efficiency in reducing the heat transfer indoors.

Thermal and economic windows design for different climate zones

Window design, especially glazing choices, is a critical factor for determining the effectiveness of passive solar design. Windows are like a knife has two side; one is useful and the other is harmful. In this paper the effects of windows’ U-value, window orientation and windows size on annual heating and cooling energy demand is studied considering the both energy and investment costs. The study has been performed for three different climate zones; Amman, Aqaba and Berlin. Four types of windows have been studied; single glazed, double glazed L, double glazed H and triple glazed.The results show that heating load is highly sensitive to windows size and type as compared with cooling load. Also, it is shown that with a well-optimized glazed window energy saving can be reached up to 21%, 20% and 24% for Amman, Aqaba and Berlin, respectively.     

双幕墙长矩形建筑风荷载特性的试验研究

以节能、生态为理念的双幕墙围护体系已逐步应用于高层办公建筑中。由于双幕墙之间存在通风廊道,因此对于双幕墙建筑有三个受风表面,即外层幕墙的内表面和外表面以及内幕墙的外表面,这使得风载取值变得复杂,目前也无规范可依。本文通过对杭州市某双幕墙办公楼的风洞试验研究,探讨了双幕墙建筑内、外层幕墙的风载取值问题;研究了门厅大跨挑篷风压分布特征,当风从侧面吹向挑篷时,挑篷上、下表面风载与普通屋盖挑篷相同,而当风从正面吹向挑篷时,挑篷上表面出现正风压,并对此现象进行了分析;文中针对该建筑物长宽比较大的特点,比较了大长宽比矩形建筑风载体型系数与规范给出的正方形建筑风载体型系数:当风沿建筑物长向流动时,采用规范给出的正方形建筑风载体型系数是可行的,当风沿建筑物进深方向流动时,其两侧及背风面的负压比正方形的大。
