Abstract
This review brings together research on the integration aspect of photovoltaic technologies in the building sector. Buildings are among the significant contributors of negative, yet not avoidable, environmental impact. Two primary drivers are pushing the building industry toward sustainability: a goal of lowering the emission levels emitted by the industry, and new norms and regulations on a zero-energy building. The zero-energy building concept is primarily based on the principle that the amount of renewable energy created on the site will be equal to the total amount of energy used by the building during its operational phase throughout its entire lifetime. As a result, the photovoltaic technology was introduced to the building sector, and from there started a rapid research and development of a merged field, building-integrated photovoltaics (BIPV). The market of BIPV is still young and is hence constantly changing. A few BIPV product manufacturers are steadily represented on the market, while new products and manufacturers are emerging and others disappearing now and then. A critical review presented herein provides technical information on existing BIPV products and systems, considering their multi-functionality as a climate screen, energy generator and aesthetic component. Therefore, this paper aims to help to understand BIPV products and systems as well as possibilities and challenges associated with their integration into the built environment of today, thus also giving guidelines for the development and design of BIPV components for the future.
Highlights
A building-integrated photovoltaic (BIPV) market is a young but fast-developing merged field of two industries – photovoltaic and building
The main objective of the present study is to provide a critical overview of existing BIPV products, illuminating significant obstacles of the market, after its analysis, and to find solutions for further market development
The service life prediction could be especially challenging for innovative components, like the BIPV products
Summary
A building-integrated photovoltaic (BIPV) market is a young but fast-developing merged field of two industries – photovoltaic and building. According to the data from the United Nations Environment Programme (UNEP), up to 40% of global energy is consumed by buildings, and they emit approximately 1/3 of greenhouse gas (GHG) emissions [1]. As energy production nowadays is primarily based on fossil fuels [1] that release GHG emissions, the level of emissions will steadily continue to grow unless severe action is taken. GHG emissions mitigation could be achieved by applying energy efficiency approaches and using renewable energy sources [1]. In this regard, the concepts of zero-energy and zeroemission buildings (ZEB) have been established, mentioned in sustainability in construction standards [3]. According to the European Parliament and the European Union Directive 2010/31/EU
