Solar water heating systems should be used in buildings. The prospects for the application of solar energy in buildings are expected to move towards the integration of solar energy and buildings. Solar and building integration is the study of solar energy and buildings as a whole. “Add-on” design is not just about “adding”, but integrating a new solution through “adding” solar water heating engineering and building integration. There are problems such as building facades that do not need sunlight, or the sunlight is too strong to increase the indoor temperature or make it difficult to use and require shading. There is also the problem that solar systems such as water heaters have to absorb. a large amount of sunlight. The future direction of development is developmentglobal development.
Definition of solar building
Solar photovoltaic building, namely building-integrated solar power (BIPV), uses solar photovoltaic materials to replace traditional building materials, making the building itself become an important source of energy without having to install a solar panel externally. Because this is taken into account from the design phase, the energy production rate and cost ratio are the best. Skylights and exterior walls are generally the brightest. receiving surfaces. It can provide part or all of the building's electricity, and existing buildings can also be transformed into solar photovoltaic buildings. The biggest advantage is that the price of solar panels can be factored into the original building materials they replace, and installation costs can also be factored into the original building materials they replace.can be taken into account in construction work, thereby reducing the cost of using solar energy. Additionally, integrating solar energy from the design phase can increase the light reception rate and improve aesthetics. These factors make solar PV the fastest growing application in the solar industry.
By using high-efficiency solar collectors and mechanical power systems to complete the heating and cooling process, a certain amount of electricity is consumed during operation of the system. Such a system is called active. solar system. Buildings designed with this system are called active solar buildings.
After design, the building components themselves can use solar energy for heating and supplement the cooling process with natural ventilation. It is not necessarye to consume electricity during system operation. passive solar system. Buildings designed with this system become passive solar buildings.
