“…Accordingly, a variety of studies have been carried out in relation to the reduction of the building energy demand through the envelope design. In this study, the above-mentioned past studies can be classified into heat insulation, opening design, and shading device (refer to Table 4) [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55]. First, in terms of the heat insulation, the studies that have been carried out to reduce buidling energy demand are as follows [40][41][42][43][44][45].…”

Abstract:To cope with 'Post-2020', each country set its national greenhouse gas (GHG) emissions reduction target (e.g., South Korea: 37%) below its business-as-usual level by 2030. Toward this end, it is necessary to implement the net-zero energy building (nZEB) in the building sector, which accounts for more than 25% of the national GHG emissions and has a great potential to reduce GHG emissions. In this context, this study conducted a state-of-the-art review of nZEB implementation strategies in terms of passive strategies (i.e., passive sustainable design and energy-saving technique) and active strategies (i.e., renewable energy (RE) and back-up system for RE). Additionally, this study proposed the following advanced strategies for nZEB implementation according to a building's life cycle: (i) integration and optimization of the passive and active strategies in the early phase of a building's life cycle; (ii) real-time monitoring of the energy performance during the usage phase of a building's life cycle. It is expected that this study can help researchers, practitioners, and policymakers understand the overall implementation strategies for realizing nZEB.

“…The control of the developed shading system doesn't use much of electric device as compared to the other existing kinds, which minimized the electricity need for operation. Furthermore, by referencing the receiving solar radiation to maximize daylighting availability from [19], a quasi-optimized movement mechanism of the blind slats could be obtained. The rotation of the blind slats is commenced by the linking horizontal pivots, which are driven exclusively by buoyancy force.…”

“…However, it is also important to consider other conditions, such as daylighting and ventilation. According to the above description and the simulated results [19], the rotation mechanism of the slats in facing various orientations to consider both for minimizing solar heat gain and maximizing daylighting and ventilation. The panel would be installed into two driving and rotating mechanisms to match up two types of the location of the building.…”

“…For instance, a shading device could be installed on the exterior of the building and designed to minimize the radiant heat and maximize illumination. Cheng et al [19] simulated the solar radiation received on various orientations of four major cities from north to south (25-22 °N) in Taiwan. The simulated data indicated that there is lower solar radiation when simulation orientations are in the ENE-WNW and SSE-SSW, compared to the other orientations.…”

Traditional dynamic shading systems are usually driven by electricity for continuously controlling the angle of blind slats to minimize the indoor solar heat gain over times. This paper proposed a novel design of buoyancy driven dynamic shading system, using only minimum amount of electricity. The energy performance and the improved thermal comfort induced by the system were simulated by EnergyPlus for a typical office space under the context of Taiwanese climate. The design processes are composed of three parts: an alterable angle of blind slats that raises the energy performance to be suitable for every orientation, the buoyancy driven transmission mechanism, and a humanized controller that ensures its convenience. The environmental friendly design aspects and control mechanisms to fulfill demands for manufacturing, assembling, maintenance and recycling, etc., were also presented as readily for building application. Besides, the effectiveness of cooling energy saving and thermal comfort enhancing were compared against the cases without exterior blinds and with traditional fixed blinds installed. The results show that the cooling energy is drastically reduced over times and the blind system is effectively enhancing the indoor thermal comfort. OPEN ACCESSEnergies 2015, 8 2359

Im Kontext der steigenden Durchschnittstemperaturen und Hitzeinselbildung in Ballungsräumen, kommt der effektiven Beschattung von Fensterflächen zunehmend größere Bedeutung zu. Während an Neubauten Beschattungslösungen im Planungsprozess integrativ behandelt werden, ist die Nachrüstung an Bestandsgebäuden oftmals technisch, aber auch gestalterisch herausfordernd. Gerade bei denkmalgeschützten Gebäuden ist die Anbringung von Beschattungselementen problematisch, da der gestalterische und konstruktive Eingriff in die historische Bausubstanz geringgehalten werden muss. Im Rahmen dieser Arbeit wird ein neuartiger Beschattungsrahmen für die Fenster‐Außenbeschattung von denkmalgeschützten Gebäuden vorgestellt und messtechnisch charakterisiert. Die Ergebnisse zeigen, dass sich das Beschattungselement gut an bestehenden Fensterkonstruktionen montieren lässt und die Ausführung mit verschieblichen Lochblechen eine gute Anpassung der Beschattungsleistung erlaubt, welche sich durch zusätzlich angebrachte Hitzeschutzfolien erheblich erhöhen lässt. Zudem zeichnet sich die Beschattungslösung im Sinne des Simple Smart Building‐Gedankens durch eine einfache, leicht zu wartende Konstruktion aus.
