Study of photovoltaic integrated prefabricated components for assembled buildings based on sensing technology supported by solar energy

Abstract

Abstract In recent years, domestic and international policies to support energy-efficient buildings have been intensively introduced, and a consensus has been reached in the direction of green buildings. Building photovoltaic integration is a key technology to solve the demand for electricity in energy-efficient buildings. Meanwhile, prefabricated assembly house construction, as a common construction technology in the current building field, has the advantages of a short construction period, low project cost, a wide range of applications, and high structural stability. Green building and building industrialization are the direction of future construction industry development, combining building photovoltaic (PV) integration with assembly building, breaking down the whole structure into simple components in the factory standardization, batch production, and then on-site assembly, can reduce the mold cost, speed up the construction speed, and improve economic efficiency. The PV solar integrated assembled facade is in line with the concept of energy saving, low carbon, and environmental protection, with significant social benefits, which helps to promote rapidly in the market. In this article, by analyzing the performance and characteristics of PV modules, we propose the design method of PV-integrated prefabricated components for assembled buildings based on sensing technology, extract relevant design parameters from the database of building PV-integrated components, and test the feasibility of the modeling scheme in four stages of engineering design. The use of the results shows that the method of this article can target to improve the accuracy of PV-integrated prefabricated components, ensure the efficiency of component production and processing, and play an important role in supporting the widespread application of modern construction technology for building PV-integrated prefabricated assemblies.
