A key review of building integrated photovoltaic (BIPV) systems

Green building and sustainable architecture are new techniques for addressing the environmental and energy crises. Trombe walls are regarded as a sustainable architectural technology for heating and ventilation. This article reviews the application of Trombe walls in buildings. The reviews discuss the characteristics of Trombe walls, including Trombe-wall configurations, and Trombe-wall technology. The advantages and disadvantages of this sustainable architectural technology have been highlighted, and future research questions have been identified.

Trombe walls: A review of opportunities and challenges in research and development

This communication presents a comprehensive review on the solar photovoltaic (SPV) systems for recent advances and their emerging applications in the present and future scenario. Besides, the performance study of off grid and grid connected SPV power plant has been discussed and presented in detail. From the literature, it is found that the efficiency of photovoltaic (PV) systems varies from 10% to 23%. Thus, the efficiency is the important factor which needs to be explored further for the best implementation and utilization of this emerging and useful technology around the globe. However, among all the applications discussed here, Building integrated photovoltaics (BIPV), Concentrated photovoltaics (CPV) and photovoltaic thermal (PV/T) are found to be the most technically sound and exhibit that SPV may be a feasible solution for the future energy challenges. Again, the building integrated PV system not only reduces the area requirement, but also cuts the material and infrastructure costs of the building and hence, fulfills the technical thrust for smart building requirements. Recently developed CPV cells are found to be feasible, most promising and cost effective technology having higher efficiency and lesser material requirements than those of the other solar cells. On the other hand, as the PV/T systems produce not only the electricity but also the heat energy are found to be more useful, suitable, and promising for most of the real life applications especially, where both forms of energy are required simultaneously.

Recent advances in solar photovoltaic systems for emerging trends and advanced applications

A major portion of the total primary energy consumed by today’s buildings is used in heating, ventilating, and air-conditioning (HVAC). Conventional heating and cooling systems are having an impact on operational cost, energy requirement and carbon dioxide emission. In this regard, Trombe walls are receiving considerable attention because of their potential ability for addressing the environmental and energy crisis. This paper reviews the most pertinent contents of studies on Trombe walls that have been carried out in the recent 15 years. According to utilizing functions of Trombe walls, they are divided into two major types: a heating-based type and a cooling-based type. In terms of content, we emphasize the introduction of three groups of parameters that be considered when designing Trombe walls: the ‘Trombe wall’ parameters, the ‘building’ parameters and the ‘site’ parameters. Then different evaluation indicators on Trombe walls have been summarized from three points of view: energy, environment and economic. We hope that this review is useful to academic researchers and can provide a reference for architects or related engineering designers in the field of passive design.

A review on the application of Trombe wall system in buildings

The building sector accounts for approximately 40% of total global energy usage. Energy consumption for space heating and cooling makes up 60% of the total consumed energy in buildings. This paper presents a comprehensive technical review of passive wall systems in building envelopes while discussing their respective capabilities in optimizing energy efficiency. Different types of energy efficient walls such as Trombe Walls, Autoclaved Aerated Concrete Walls, Double Skin Walls, and Green Walls are explored. Furthermore, novel concepts for optimizing energy efficiency in building envelopes are also introduced. Finally the utilization of passive wall systems to save energy while improving the building environmental impacts is discussed.

Application of passive wall systems for improving the energy efficiency in buildings: A comprehensive review

Many countries around the world are confronted with the challenge of decreasing energy consumption, while the use of electrical appliances is continuously increasing in buildings The requirement to minimize the energy consumption can be fulfilled by revaluating architectural aspects One of these aspects is related to overheating problems, caused by facades with large, glazed portions In such designs, shading elements must carefully be integrated and considered at an early-design stage in the design process Shading of buildings is crucial especially in climates with hot summer It is significant to protect the window from solar radiation in summer while allowing maximum solar radiation in winter For this reason, precise figures of their performance are needed As such, simulation tools are often used for identifying the most suitable shading element that suits the building In literature, there are many studies that have been done to designate the energy performance of shading devices in buildings by using simulation tools This study focuses both on the shading device types used in the building sector and the previous studies done for designating the performance aspects of different shading devices types Numerous studies for different building types located in different climatic regions have been reviewed in order to underline the importance of simulation modeling for shading devices in buildings

An approach for energy modeling of a building integrated photovoltaic (BIPV) Trombe wall system

Facades constitute one of the fundamental systems of contemporary buildings. They serve multiple purposes, such as to ensure proper indoor climate, to provide sufficient daylight, but also to create a desirable architectural image. Integration of these aspects makes facade design a complex task that requires significant effort in order to achieve well-performing results. It is thus desirable that systematic approaches to facade design are developed. In this study, we consider facade design as a multiobjective optimization problem, integrating diverse design criteria, namely indoor daylight distribution, structural performance and cost. We evaluate design performance by making use of simulation. Consequently, we use Differential Evolution (DE) to search for best-tradeoff solutions. We compare the performance of two DE variants, using the Hypervolume metric, and also through qualitative inspection. We report facade designs that demonstrate interesting and often unexpected features, concluding that the proposed approach may lead to a novel, more integrated design process.

Multi-objective diagrid façade optimization using differential evolution

The reduction of energy consumption is a major challenge around the world. Architectural aspects have a significant place to minimize energy consumption to the maximum level. The use of large glazed facades causes overheating problems in certain climatic regions. Shading elements must be considered at an early stage in the design process to overcome this problem. An application of the method is presented, focusing on the horizontal louvers integrated to a building in Izmir, Turkey. The contributions of the paper can be summarized as follows. We show that most architectural design problems are basically real-parameter multi-objective constrained optimization problems. So, any type of evolutionary and swarm optimization methods can be used in this field. A multi-objective self-adaptive differential evolution algorithm (jDEMO), inspired from the DEMO algorithm from the literature with some modifications, is developed and compared to the well-known fast and non-dominated sorting genetic algorithm so called NSGA-II in order to solve this complex problem and identify alternative design solutions to decision makers. Through the experimental results, we show that the proposed algorithm generated slightly better results when comparing to the NSGA-II algorithm.
