1. Elevated Buildings: For natural ventilation and cooling without additional cooling measures, the eaves should be elevated, with a recommendation of 3.5 meters or more. If other cooling methods such as shading, fans, and fogging are employed, the eaves height can be slightly reduced, but there is still a minimum limit, and it is advisable to maintain a height of over 3 meters.
2. Allowable ascending hot air to exit from above: Tai Zi Lou-style, side-swinging, or asymmetric sloping (saw-tooth) roofs fall into this category of architecture, where exhaust fans can be installed below the openings to enhance ventilation.
3. Embrace open or semi-open architectural design: Utilize natural ventilation to cool down, taking advantage of site selection and wind directions during summer.
4. Roof Sprinkling: Directly spray water onto the glass greenhouse roof to remove latent heat through evaporation, thereby lowering the roof temperature. The water that does not evaporate can be collected and reused through the gutter.
5. Utilize External Shading: The external shading system can be installed in a fixed manner, with the shading net at least 20 cm away from the roof to allow for air circulation.
6. Utilizing Internal Shading: The purpose is to block heat above the shading net, using fans to exhaust the hot air above. The internal shading system should be retractable, with care taken to ensure the path of lower-level air flow to the roof's upper opening is not blocked when opened.
7. Utilizing Side Shading: Both expandable and winch-type side shading systems can block intense sunlight under strong sunlight exposure. However, for the purpose of cooling, an extended glass greenhouse is more effective than a wrapped one, as the former extends from the eaves, while the latter reduces the area of the inlet when wrapped. The latter's benefits include space-saving, affordability, and providing insulation and wind protection during low temperatures or strong winds. The side wall on the west side needs to be particularly shaded during the afternoon.
