“…Moreover, Figure 7 shows that heat gain cut down by almost 65% throughout all the five orientations, which is related to that transmittance of glass is much higher than that of BIPV modules [36]. Tian et al [37] examined the energy potential of semi-transparent photovoltaic windows in terms of energy output, the energy consumption of lighting and energy consumption of air conditioning. The result showed that semi-transparent photovoltaic windows able to save nearly 30% of the total building load on a standard sunny day.…”

Fossil fuel consumption for electricity generation in the building sector is at an all-time high in line with the country’s economic growth. This scenario will increase the global CO2 emissions and large carbon footprints, thus leading to global warming. In recent years, most of the research related to the building sector has focused on the development of new techniques to reduce buildings’ energy consumption through energy conservation, energy efficiency, and the implementation of renewable energy technologies. The introduction of photovoltaic (PV) technology has become the most prominent renewable energy (RE) that can be integrated into building components. Even though the Building Integrated Photovoltaic (BIPV) has been available for decades, but its implementation in Southeast Asian countries has not gained widespread acceptance compared to European countries and other parts of Asia. This paper aims to investigate the effects and challenges of BIPV implementation in Southeast Asian Countries (Cambodia, Indonesia, Laos, Malaysia, Singapore, Thailand, Vietnam, and the Philippines), focusing on climate effects, the initial cost of PV technology, government policies, and initiatives. An in-depth literature review from past research, policies, and reports taken between 2016 to 2021 has been conducted and found that the environmental parameters directly influence the performance of BIPV systems and affect efficiency. This study pointed at Feed-in Tariff (FiT), policies and initiatives offered by the government in Southeast Asian countries are not beneficial and discourage building owners to adopt the BIPV technology or any other RE technology. Governments should revise the current policies to promote and attract more building owners to take part in the efforts to minimize CO2 emissions from the building industry.

“…The study reported annual energy saving of 322.9 kWh with a panel efficiency of 13%, payback period of 13.8 yrs. Similarly, Tian et al [46] analyzed the energy saving potential of semi-transparent PV (STPV) window made of amorphous silicon (a-silicon) at four sites in Southwest China. The energy generated at these sites was reported to be 402.1, 314.1, 233.55, and 216.5 kWh at Lhasa, Kunming, Chengdu, Guiyang sites, respectively.…”

Saudi Arabia has embarked on diversification of its existing energy portfolio through rene wables, mainly solar photovoltaic and thermal, and wind power. This study presents an overview of how different areas around the world utilized building-integrated solar photovoltaic applications to recommend appropriate and suitable options for implementation in Saudi Arabia and the Middle East region. With this objective, the power utility will have three-fold benefits (i) clean and economic power arability for off-grid remotely located dwellings, (ii) cutting down the emissions of greenhouse gases, and (iii) conserving the fixed reserves of fossil fuels, which are being used mainly for power production around the world. The study shows that building-integrated applications are most common in Asian and European countries. Moreover, it is observed that monocrystalline and polycrystalline photovoltaic materials are both technologically and economically suitable for such applications.

“…Indeed, about 80% of the BIPV's installations are roof-mounted and the remaining ones 20% are mounted on the facade in which they act as a rain screen (Hestnes, 1999). Due to the recent advancements in terms of solar energy technology, BIPV cannot only be perfectly integrated into buildings, but also can provide more aesthetic architectural expression, such as coherent variations in proportions, surfaces, models, colors, and textures (Tian et al, 2018). Also, BIPV can be composed of semi-transparent PV panels that can be successfully integrated into architectural glazing.…”

Building in urban areas in the Sahara region is confronted with two main issues: (i) the climate change and (ii) the energy consumption. In order to deal with the latest issues, experts want to focus all their efforts in the use of renewable energy, and most particularly solar energy that is widely available at the Sahara. In this work, we first analyzed the proposed works related to both environmental impact and integration of solar energy in the building. Secondly, we have accurately defined the new concept of Building Integrated Photovoltaic (BIPV), its advantage to minimize the building energy consumption, and its role to reduce greenhouse gas emissions and greenhouse effect due to fossil fuels. Thirdly, we have carried out a comprehensive survey related to benefits, techniques, and criteria affecting the energy efficiency of using BIPV and its advantages over glazing. To be clearer, we have selected as a case of study of a contemporary building covered by standard glazing and replaced by BIPV located in a Sahara region in Algeria. Moreover, the point of view of urban architectural, environmental, and energy economy, has been well investigated. As a result, using BIPV in this specific region of a hot climate has to be a dominant idea to reduce both energy consumption and economical budget.
