Consider the building type and functional requirements
The design requirements for Fire Smoke Exhaust Skylight vary greatly for different types of buildings. For industrial buildings, due to the large internal space and the possibility of more smoke and heat sources, the smoke exhaust volume of Fire Smoke Exhaust Skylight must be large enough, and the opening area usually needs to be determined based on the plant area, the scale of fire that may occur in the production process, etc. For example, a large-scale mechanical processing plant may need to disperse large-area smoke exhaust skylights to ensure that smoke and heat can be quickly exhausted in the event of a fire, and to ensure clear escape and fire rescue passages. For commercial buildings, such as shopping malls, which are densely populated and complex in space, Fire Smoke Exhaust Skylight must not only consider smoke exhaust, but also consider the integration with the overall beauty of the building and the coverage of different floors and functional areas. It is necessary to design appropriate opening methods and locations according to different spatial layouts such as atriums, corridors, and shops to ensure the smoke exhaust effect without affecting normal business activities.
Design based on building height and number of floors
The design of Fire Smoke Exhaust Skylight in high-rise buildings faces greater challenges. As the building height increases, the chimney effect becomes more obvious, and the design of the smoke exhaust skylight should make full use of this effect. In super high-rise buildings, it may be necessary to set up smoke exhaust skylights in layers, and the impact of wind pressure changes at different heights on smoke exhaust should be considered. For example, smoke exhaust skylights set up on high floors need to have sufficient wind pressure resistance to prevent them from being unable to open normally or being damaged in strong winds. For multi-story buildings, the wind pressure has a relatively small impact, but it should be noted that the arrangement of smoke exhaust skylights should cover all floors to avoid dead corners for smoke exhaust. The layout of smoke exhaust skylights can be reasonably planned according to the location of key parts such as stairwells and evacuation passages to ensure that smoke can be discharged smoothly and buy time for personnel evacuation.
Combine the building's plane layout and spatial form
The plane layout and spatial form of the building are diverse, which is crucial to the design of Fire Smoke Exhaust Skylight. If the building is long and narrow, the smoke exhaust skylights can be evenly arranged along the length of the building to form a coherent smoke exhaust passage. For buildings with courtyards or atriums, large centralized smoke exhaust skylights can be set above the atrium, and auxiliary smoke exhaust skylights can be set in the surrounding areas according to functional zoning and the possibility of fire spread. For irregular-shaped building spaces, detailed fire simulation analysis should be used to determine the location and number of smoke exhaust skylights to ensure that every corner can be effectively protected from smoke exhaust in the event of a fire. For example, smoke exhaust skylights can be reasonably set at special locations such as protruding parts and corners of the building.
Special design for special building structures
Some special building structures require special Fire Smoke Exhaust Skylight designs. For example, for large-span arched building structures, the design of smoke exhaust skylights should consider the mechanical coordination with the arched structure and should not affect the overall stability of the building. In this case, curved smoke exhaust skylights that match the arched structure can be used, or smoke exhaust ports can be reasonably set at the top and both sides of the arched structure. For underground spaces that are connected to ground buildings, smoke exhaust skylights need to be set at the connection points. At the same time, the possibility of smoke from underground spaces spreading to the ground should be considered, and reasonable fire separation and smoke exhaust systems should be designed to ensure the fire safety of the entire building.
