With rapid urban development, public space is becoming increasingly scarce, especially in old urban districts where land is extremely precious. Ground-level space is valuable and sometimes cannot meet the public's demand for sports venues. Utilizing idle rooftop space on buildings and converting it into sports grounds with open views and fresh air can not only provide citizens with more sports options, but also add teaching resources and activity venues for schools and educational institutions, enrich students' extracurricular lives, and promote their all-round development.

In addition to common running tracks, various ball sports courts can be set up, such as basketball, football, volleyball, tennis, badminton, and table tennis. The appropriate court configuration should be selected based on the actual rooftop area and structural load-bearing capacity. If conditions permit, a swimming pool can also be built, or extreme sports such as roller skating, skateboarding, and rock climbing can be offered.

Ball sports courts must be surrounded by enclosed fencing (netting) on all four sides; if conditions permit, five-sided enclosure (i.e., with the top also enclosed) is recommended. The height of the fencing (netting), mesh size, and column dimensions and spacing must comply with relevant technical standards, and should be comprehensively considered in conjunction with factors such as wind force and roof height.

Sports equipment placed for long periods should be fixed in place to prevent it from being blown down during typhoons and causing safety hazards. If a rooftop swimming pool is built, waterproofing must be properly handled; if the sports area is located above classrooms, effective sound insulation and vibration prevention measures must be taken to avoid affecting normal teaching.

In addition to the sports areas, auxiliary rooms and the overall rooftop environment must be rationally designed, with scientific zoning to ensure the long-term operation of the rooftop sports field. For example, auxiliary rooms such as changing rooms, shower rooms, restrooms, equipment rooms, spectator stands, and lounges should be built according to actual needs, while rooftop equipment should be centrally arranged and screened with grilles or vertical greening.

Rooftop photovoltaics can be divided intotwo major categoriesone is building-integrated photovoltaics, such as photovoltaic curtain walls, photovoltaic glass, and photovoltaic tiles, which directly serve as part of the building facade and are suitable for new buildings; the other is photovoltaic power generation systems, which are attached separately to buildings, including photovoltaic thin films, monocrystalline silicon, and polycrystalline silicon solar panels. Rooftop photovoltaic panel installation generally belongs to the latter.

First, the roof must undergo a "checkup" to confirm that its load-bearing and waterproofing performance meet installation requirements. Second, lighting and orientation conditions must be considered. In the Northern Hemisphere, south-facing roofs have the highest power generation efficiency, while east- and west-facing roofs generate about 20% less electricity. If the roof faces north or is shaded by large trees, tall buildings, or other obstructions, power generation will be affected. In addition, lightning protection grounding wires must be installed during installation, heat dissipation gaps must be reserved between the photovoltaic panels and the roof, and regular line inspections and photovoltaic panel cleaning and maintenance must be carried out.

Converting solar energy into electricity through rooftop photovoltaics can be used for household power supply and energy storage, which is both environmentally friendly and saves on electricity bills; at the same time, photovoltaic panels can provide shading and heat insulation for the roof, better adapting to the climate conditions of the Lingnan region.
