<p>In terms of rehabilitation of existing buildings, a new façade is often planned and build to make the building more sustainable. In more and more cases, not only new windows, but also completely new façades and even so-called double skin facades are being constructed. This second skin has several advantages like sound protection, possibility of natural ventilation, contribution to energy balance and others. The paper will give basic requirements and information about this type of facade. One recently realized project is a high rise building of more than 100m height in Munich, listed as a historic building – so additional attention to optical appearance was necessary. And moreover, curved insolation glass units had to be used; since there are no regulations, special theoretical investigations and calculations had to be carried out.</p>

Double Skin Facades

There was an indication that high rise buildings in Jakarta was not designed based on energy conservation principles. The most important aspects of the high-rise buildings is energy saving technology located in the building envelope design. Building envelope with a full glass design functions for widening view and enhancing natural lights, even though but it is also increasing energy consumption and thermal discomfort due to the intensity of solar radiation in hot humid climates. During the current decade, the development of double building envelope type (Double Skin Façade: DSF) seemed more just to improve the aesthetics and the use of natural light, while the wind and thermal performance aspects were still lack of serious consideration. Those aspects will be chosen as the subject matter in this research. The research was aimed to investigate and compare the value of heat transfer in the building envelope of high-rise office buildings. Samples were taken from five DSF buildings, with closed and open cavity. CFD software is used for simulation of the five different models of DSF. The research proves that the high-rise office buildings as the research object in Jakarta do not apply energy conservation principle. The utilization of wind in the DSF cavity can reduce temperature and relieve the burden of air conditioning systems that is energy save. An important finding of the research is the need for ventilation in the design of a double skin at high-rise office buildings in the humid tropics.

Double Skin Facades

Building envelope on high-rise office buildings have an important role of energy consumed. There are many methods and techniques that can be used to achieve this goal through energy efficiency for building envelope in the tropic area. The use of glass material becomes one of the alternatives that offer a more attractive appearance. Although the double skin facades (DSF) has been widely applied, but research on the thermal performance and behavior of the wind is still scarce for the tropics, so it is interesting to note related to energy conservation. To obtain a clear picture of the heat transfer and airflow, the research was conducted on the two office buildings with the same orientation and location but they were different on the building envelope. The study was conducted by the field measurements and simulation using CFD-ACE + software, to determine the performance of the heat transfer and behavior of airflow in the double skin facades. The results indicate that the role of wind on the design building envelope has an influence on the heat transfer and energy savings. Key words: wind, double skin facade, heat transfer, CFD, energy

Within an ongoing project, we explore the potential of double skin facades to provide both noise control and natural ventilation capability. Three strategies are investigated: i) Manipulation of sound paths via offset of the openings in the two shells of the façade; ii) Application of absorbing materials in the interstitial space of the façade; iii) Active noise cancelling methods utilizing wave-destructive interference. This contribution describes the overall project but focuses primarily on the active noise cancellation approach. Aside from a comprehensive background research on existing technology, we undertook the design of an actual setting for noise cancellation testing with suitable low-cost components as a proof-of-concept. Results of the experiments are expected to inform subsequent efforts to include noise-cancelling technology in double skin facades.
