Summary:To address the global energy problem, energy from the solar source remains the most encouraging solution for buildings with a difficult-to-achieve goal such as achieving zero net energy consumption. In a solar thermal system, integrated solar collectors in buildings can convert the absorbed solar energy into thermal energy and can be better exploited in an area of the facade, while acting as an integral component of the building envelope, with good sun exposure. The aesthetic character and functionality of this technology are of great interest. The number of BIST (BUILDING INTEGRATED SOLAR THERMAL) products with heat recovery on the market remains limited. The implementation of this technology can be explained by the lack of information on the cost-benefit ratio, high cost, lack of tools for estimating energy production and lack of complete integration and functionality solutions. In this design model of flat solar collectors (FPC), it will be possible to deduce the total surface based on the assigned thermal load volume, temperatures, efficiency, energy equations, total area of FPC (Flat plate collectors). The assessment of these parameters is very different depending on the type and utility of buildings, climatic conditions, location, construction, and aesthetic considerations. The aim of this article is to help remove certain obstacles that slow down the adoption of solar collector integration and heat recovery by improving knowledge about their performance characterization and its real benefits.
