Design and Energy Performance of a Buoyancy Driven Exterior Shading Device for Building Application in Taiwan

Abstract

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

The comparison of device materials of sliding sudare using a prototyping method

“…This prototyping process aims to measure the feasibility of, evaluate, and identify issues that might appear during the Sliding Sudare production, specifically concerning its material selection. The resulting prototypes will undergo an evaluation based on several parameters referring to Huang, Liu, and Liang (2015)'s important aspects of material selection, namely (1) security requirement, (2) weather resistance, (3) construction, and (4) costeffectiveness. A more detailed explanation of these parameters is provided in the latter part of the manuscript.…”

“…To implement an adaptive shading device system into a building, several design stages require to be executed with regard to use's comfort, cost, and technical feasibility (Carlett i, Sciurpi, and Pierangioli 2014). According to Huang, the number of design processes to set out the adaptive shading device include; determining the user's need, determining design specifications, selecting material, formulating the design regarding its function and construction, and fulfilling design stages in detail (Huang, Liu , and Liang 2015). Meanwhile, Romano (2018) classifies the readiness of the adaptive shading device into several categories, namely: (1) observed/reported basic principles/idea, (2) formulated technology concept/design, (3) proposal, (4) validated technology in the laboratory, (5) prototype demonstration, and (6) commercial product/existing building (Aelenei et al 2018).…”

“…In that case, the material can be quickly damaged and cannot withstand exposure to the extreme weather. Due to its lack of development, this research aims to start an investigation regarding the potential material utilization for developing Sliding Sudare into an adaptive shading device system that meet the requirements desired This material study holds an essential position in influencing the overall functional, structural, and detailed design of the device (Huang, Liu, and Liang 2015). Knowing that material selection is a crucial aspect of the shading device's working system, this research focuses on the exploration of probable materials to set out Sliding Sudare.…”

Radiometric Characterization, Solar and Thermal Radiation in a Greenhouse as Affected by Shading Configuration in an Arid Climate

“…Plastic nets are widely used all over the world for shading residential buildings to reduce heating and cooling loads [19][20][21] and in agricultural sectors for plant and animal protection purposes. This is because plastic nets offer many environmental and economical advantages [1][2][3][4]18,22].…”
