“…Smart glass technologies include SPDs, EC devices and LCDs [45]. Installing smart glass in buildings' envelope, is similar to creating climate adaptable building shells, in which costs for heating, cooling and lighting are reduced [46,47]. Additionally, smart glass prevents 99.4% of ultraviolet light, which reduces furniture and curtain fabric fading [44,45].…”

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.

“…Over the past decades, computer-aided simulation of buildings has become widely available; hence these days, it is used both in research and in industry [7]. Loonen et al [8], analysed the factors that affect the success and failure of innovations in construction industry and demonstrated the potential of using whole-building performance simulation in the domain of research and development. They concluded that the lack of effective communication about performance aspects was one of the most significant barriers to innovative building technologies and components.…”

“…Building Energy Performance Simulation (BEPS) tools have gained tremendous importance for analyzing energy efficient building designs since they consider the dynamic thermal behavior of buildings, climatic conditions, and user behavior [6]. Several studies [7][8][9][10][11][12][13][14] have shown that the active and passive elements can be simulated successfully for informed, rational decision-making.…”

This paper presents a simulation study to reduce heating and cooling energy demand of a school building in Seoul Metropolitan Area, Korea. The aim of this study was to estimate the impact of passive vs. active approaches on energy savings in buildings using EnergyPlus simulation. By controlling lighting, the energy saving of the original school building design was found most significant, and increased by 32% when the design was improved. It is noteworthy that energy saving potential of each room varies significantly depending on the rooms' thermal characteristics and orientation. Thus, the analysis of energy saving should be introduced at the individual space level, not at the whole building level. Additionally, the simulation studies should be involved for rational decision-making. Finally, it was concluded that priority should be given to passive building design strategies, such as building orientation, as well as control and utilization of solar radiation. These passive energy saving strategies are related to urban, architectural design, and engineering issues, and are more beneficial in terms of energy savings than active strategies.
