Abstract
Solar energy is a new renewable energy. Using solar energy to generate electricity is an effective means to achieve sustainable development. The huge roof at the top of the airport is a natural interface to receive solar energy, which can be used to supply the energy needed by the airport through building integrated photovoltaic design. However, due to the curved shape of the airport roof, there are limitations in solar energy acquisition and construction of the airport roof. In this paper, the method of “ruled surface fitting-solar radiation analysis-modular unit arrangement” is used to optimize the shape of the non-linear airport roof, and convert the complex roof surface shape into a straight line with good sunlight performance and easy construction. The ruled surface can better integrate BIPV and nonlinear airport, and improve the solar power generation efficiency of the building, thus improving the sustainable performance of the building.
Highlights
With the rapid development of economy, the concept of sustainable development has become increasingly popular in the world
Based on the nonlinear airport roof shape, this paper introduces the ruled surface architecture logic under the premise of meeting its form and function requirements
The analysis shows that the scheme has high solar radiation acquisition amount, good morphology fit, full sunlight receiving area and the best comprehensive performance in the three years
Summary
With the rapid development of economy, the concept of sustainable development has become increasingly popular in the world. The introduction of building integrated photovoltaic is in line with China's strategic planning for sustainable development of energy in the 21st century, and an important part of developing a circular economic model and the construction of a harmonious society. In order to meet the airport energy demand without damaging the ecological environment, the use of solar power generation, especially the large-scale development and application of BIPV is important. The huge building volume and large roof area of the airport are favorable conditions to apply the buildings integration photovoltaic in the airport. The airport roof area is large, the shape is usually gentle and complete, and the complexity of the form is low, which meets the requirements of photovoltaic integration for uniform and smooth interface receiving light. This article takes the corridor type of typical airport roof as an example, and elaborates the design method of airport photovoltaic roof in detail
