The building integrated photovoltaic (BIPV) system have recently drawn interest and have demonstrated high potential to assist building owners supply both thermal and electrical loads. In this paper, the BIPV technology has been reviewed, in terms of its performance, efficiency and power generation capacity. Specifically, the applications of the BIPV in tropical climate regions have been discussed, together with its prospects and challenges. For these schemes to be implemented in a tropical climatic region, the following issues must be considered: 1) Certain studies must be done relating to electrical load demand, predicted PV output, location of the buildings and its integration and constraints associated with roof design; 2) For the highest energy production from solar PV, the solar collectors need to be with the right tilt depending on the location; 3) Design criteria such as safety, efficiency, durability, flexibility and constructive issues need to be considered; 4) The government of such countries must train electricians and carpenters on PV installations; 5) The BIPV roofing must perform same function as normal roofing materials, such as noise protection, water tightness, insulation and climate protection, and 6) As practiced around the world, these countries must establish design standards for the BIPV.

The hybrid photovoltaic-thermal system has shown great progress. Electrical energy is produced from PV panels while thermal energy is produced via a working fluid carried through the panels. In this paper, the vertical PV/T is introduced using working fluids such as air and liquid, which serve to control the excess temperature of the PV panels as well as to collect heat to be made available as thermal energy. Installations of PV/T systems on building façades, as well as integration with other technologies such as heat pipe and heat pump are also discussed. Current studies of such building integration technologies are also explored, including the scale of application. This study aims to provide constructive information which can be used in future development of building facades for large-scale applications, to contribute to future sustainable development. Practical application: This study helps researchers and engineers who are considering photovoltaic thermal systems for building façades to have better understanding of its effect on electrical and thermal energy – for space heating, fresh air supply and hot water supply – using an active building envelope.

Summary
Zero or low‐carbon buildings can be achieved through novel technology solutions and integrating renewable energy into the buildings. One method of reducing the fossil fuel dependency of buildings and limiting greenhouse gas emissions is integrating the solar thermal system into the built environment. Recently, transpired solar collector has been identified as 1 of the most efficient solar thermal conversion technologies where a very high efficiency can be achieved. The proposed review paper investigates the performance of transpired solar collectors (TSCs) and discusses the relevant case studies in this context. This paper introduces the background and concept of TSCs. It mainly focuses on the study of parametric dependency of the performance of TSCs. The paper also investigates various mathematical models, experimental study, and numerical simulations particularly CFD used for TSC performance analysis. This proposed paper concluded that wind speed and airflow rate are the most dominant factor in TSC performance but solar irradiation, hole diameter, hole geometry, and pitch size have limited effect on TSC performance; also, profile with longer pitch tends to lower the collector efficiency and heat transfer coefficient. However, profile with shorter pitch tends to reduce the wind effect.
