“…The results showed a 3 • C decrease in the indoor air temperature due to the control of incoming solar radiation [122]. Kim et al performed a study on a PV-integrated adjustable shading device combined with daylight responsive dimming system in Korea and results showed 32% increase of power production and a 35% reduction of energy consumed by lighting systems [123].…”

Active shading systems in buildings have emerged as a high performing shading solution that selectively and optimally controls daylight and heat gains. Active shading systems are increasingly used in buildings, due to their ability to mainly improve the building environment, reduce energy consumption and in some cases generate energy. They may be categorized into three classes: smart glazing, kinetic shading and integrated renewable energy shading. This paper reviews the current status of the different types in terms of design principle and working mechanism of the systems, performance, control strategies and building applications. Challenges, limitations and future opportunities of the systems are then discussed. The review highlights that despite its high initial cost, the electrochromic (EC) glazing is the most applied smart glazing due to the extensive use of glass in buildings under all climatic conditions. In terms of external shadings, the rotating shading type is the predominantly used one in buildings due to its low initial cost. Algae façades and folding shading systems are still emerging types, with high initial and maintenance costs and requiring specialist installers. The algae façade systems and PV integrated shading systems are a promising solution due to their dual benefits of providing shading and generating electricity. Active shading systems were found to save 12 to 50% of the building cooling electricity consumption.

This study aims to design and develop the prototype models of the smart photovoltaic system blind (SPSB). To achieve this objective, the study defined the properties in three ways: (i) the photovoltaic (PV) panel; (ii) the tracking system; and (iii) the monitoring system. First, the amorphous silicon PV panel was determined as a PV panel, and the width and length of the PV panel were determined to be 50 mm and 250 mm, respectively. Second, the four tracker types (i.e., fixed type, vertical single-axis tracker, horizontal single-axis tracker, and azimuth-altitude dual-axis tracker) was applied, as well as the direct tracking method based on the amount of electricity generated as a tracking system. Third, the electricity generation and environmental conditions were chosen as factors to be monitored in order to evaluate and manage the technical performance of SPSB as a monitoring system. The prototype model of the SPSB is designed and developed for providing the electricity generated from its PV panel, as well as for reducing the indoor cooling demands through the blind's function, itself (i.e., blocking out sunlight).

“…One of the most influential parameters determining the PVSD's performance is the angle of inclination; that helps ensure an optimum value for both internal solar gain control and electric generation (Bahr, 2013, Kim et al, 2014. Probably one of the most worked over from different perspectives, yet still one of the least agreed upon areas at envelope level, is the tilt angle of the PV panels (Bahr, 2009, Bahr, 2014, Jung, 2014, Kim et al, 2010, Yang and Lu, 2005.…”

High solar gain in hot and arid climates, causes overheating in summer and increases the demand for air-conditioning, energy and carbon footprints of buildings. There are different strategies, tools, and solutions to address this problem, but Integrated Façade Systems (IFS) -façade systems where different technological solutions are integrated to improve performance and to lower the impact of the building -are still an under-developed yet a fast-growing field of research. Such systems can reduce solar heat gain, lower air conditioning costs and lessen glare, while maximising the use of natural light and help produce energy if combined with PV technology. Previous research has addressed one or a combination of some of the influential factors on performance of such systems, yet there still is a gap in the state-of-the-art research in comprehensive systematic approach not only to help gauge the impact of alteration of parameters on the IFS performance, but also an approach which can be deployed in other studies where the focus is on façade systems. With a special reference to office buildings in hot and arid climates, this paper sets out to systematically identify IFS parameters which have potential impacts on energy, lighting, glare and heat gain. Then as a part of a comprehensive ongoing research in this area, this paper presents a proof-of-concept to demonstrate the application of such methodology to a parametric study of IFS technology. In doing so, it chooses only one of the parameters indicated in this systematic review and uses building simulation as its core method to investigate the influence and impacts of those variations on performance of IFS. It will indicate how this approach provides high flexibility to adjust or configure any combination of those parameters and to measure, subjectively, how this will result in change in façade performance.
