Teknaf, Cox’s Bazar is a coastal region that is a vital ecological site. To preserve the area, extensive subterranean building is deliberately avoided. Invasion of the foundation and substructures is minimal. For minimally invasive substructures, marine-grade concrete with corrosion- and salinity-resistant additives (such as pozzolanic additives or corrosion inhibitors) is utilized. There is very minimal disturbance even at ground level. Because the building's ground area makes up less than 20% of the entire site, it allows for diligent planting that gives guests a real ecological experience without endangering the ecosystem. There is embankment at the coastline and the site is already elevated at least 15 feet from mean sea level by sand filling and stabilizing the soil.
For superstructures reinforced cement concrete structures are used with a shell. Aluminum composite panel sheet serves as the shell's sheeting material. Because of its strength, adaptability, and environmentally beneficial qualities, aluminum composite panels or ACPs are being utilized more and more in coastal regions and sustainable construction projects. ACP sheets are ideal for usage in coastal areas because of their strong resistance to corrosion brought on by moisture and seawater. For further defense against oxidation and corrosion, polyester resin or PVDF (polyvinylidene fluoride) is applied to the aluminum layers. Strong winds, heavy rainfall, and UV rays—all of which are typical in coastal areas can be tolerated by ACP panels. Long periods of exposure to sunlight and salty air do not cause them to distort, peel, or deteriorate. Effective thermal insulation from ACP sheets lowers heat gain in structures. This reduces the amount of energy needed for cooling, particularly in hot coastal regions. Aluminum and polyethylene, two recyclable components, are used to make ACP panels. The environmental impact of recycling aluminum is greatly reduced because it only uses 5% of the energy required to generate new aluminum. It is also smooth, non-porous, easy to clean, and aesthetically pleasing, all of which blend in well with the seaside landscape. It is lightweight and durable, which lowers the overall structural load. it is also fire resistant and its production ensures low carbon footprint.
For this project, where long spans, durability, and cyclone protection are crucial, using an exoskeleton steel truss system has many of benefits. The steel's performance in the coastal environment is further improved by coating it to prevent oxidation. It creates open, flexible areas ideal for exhibition galleries by providing effective structural supports and distributing loads equally. As steel trusses are so durable and lightweight, they can support the heavy wind loads that are common in Teknaf's cyclonic conditions. By allowing airflow through the structure, the exoskeleton truss system minimizes uplift forces during cyclones and reduces wind resistance. In the coastal climate of Teknaf, oxidation brought on by the salt-laden air is prevented by applying a protective coating (galvanization or polyvinylidene fluoride coating). The 360 observatory is basically a spiral ramp supported by two slanted columns with steel cables.
Multilayered glare-free ETFE glass enhances the structure and creates a more comfortable environment for exhibitions and visitors by letting in natural light and preventing glare. Its strength and light weight allow it to survive coastal conditions including storms, UV radiation, and salty air while also lowering structural load. Its thermal insulation lowers cooling costs, and its self-cleaning surface minimizes maintenance. Because it is recyclable, flexible, and encourages sustainable building practices, ETFE is a fantastic choice for Teknaf's surroundings.
There are service elevators on either side of the entrance ramp, and service carts are available throughout the structure. The Natural History Museum's elements are gathered through field collections, donations, partnerships, or rescue operations in accordance with legal and ethical guidelines. To prevent decomposition, specimens are handled, cataloged, and stored in controlled environments after collection. These elements are crucial for taxonomic research, ecological studies, and comparative analysis, which advances our understanding of biodiversity, climate research, and conservation efforts. While some specimens are used by researchers for publications, medicinal applications, and educational purposes, others are displayed in galleries to engage the general public.
