5 Design Considerations When Building In Harsh Environments

Engineering in harsh environments

As an industry, engineering is always about adaptability. After all, no amount of high-grade construction can stand the test of time if it doesn’t survive its environment.

Engineering in harsh environments poses a distinct set of challenges that call for innovative and robust design solutions. This article delves into the five most crucial ones, such as military shelter systems and remote research stations, to ensure structural integrity, functionality, and longevity.

1. Material Selection

Selecting the appropriate materials is essential for designing structures in harsh environments. They must demonstrate exceptional resistance to factors like extreme temperatures, corrosive elements, or high winds. Additionally, they should be low-maintenance, cost-effective, and readily available. 

Engineers typically consider the following materials for such applications: 

  • High-performance concrete: Reinforced with fibers or other additives, this material offers increased strength, durability, and resistance to cracking and corrosion. 
  • Stainless steel: With its corrosion resistance, stainless steel is particularly suitable for projects in marine environments or areas with high humidity. 
  • Advanced composites: Materials like carbon fiber or glass fiber-reinforced polymers provide excellent strength-to-weight ratios and resistance to environmental degradation. 

When designing military shelter systems, the material choice becomes even more critical. The chosen materials must provide adequate protection against threats such as ballistic impacts and chemical, biological, radiological, and nuclear (CBRN) hazards while maintaining the desired performance characteristics.

2. Structural Design And Modularity

Structural design is crucial for ensuring the stability and longevity of structures in harsh environments. Engineers must account for various loads and stresses, such as wind, snow, seismic, and thermal loads, to prevent potential failure or collapse. 

Modularity is significant for structures like military shelter systems, enabling easy transportation, assembly, and disassembly in remote or hostile locations. This approach ensures quick building and dismantling, minimizing time spent in harsh environments and reducing damage or injury risk.

3. Energy Efficiency And Sustainability

Energy efficiency and sustainability are key considerations when designing structures for extreme environments. The remoteness of these locations often implies limited access to power, making energy-efficient systems and renewable energy sources indispensable.

Some energy-efficient design strategies to consider include:

  • Passive solar design: Optimize the building’s orientation, insulation, and thermal mass to reduce heating and cooling requirements.
  • High-performance glazing: Double or triple-glazed windows minimize heat transfer and improve insulation.
  • Energy-efficient lighting and appliances: Select low-energy lighting solutions and devices to reduce overall energy consumption.

Renewable energy sources, like solar panels or wind turbines, can offer a sustainable and reliable power supply for the structure. Additionally, using local and recycled materials can help reduce environmental impact and transportation costs.

4. Adaptability And Flexibility

Designing flexible structures that can respond to changing environmental conditions is critical for long-term viability. It can be achieved through adjustable or movable components, such as retractable roofs, mobile shading devices, or movable walls. 

For shelter systems, flexibility may involve accommodating different functional requirements, such as medical facilities, command centers, or sleeping quarters. The modular design mentioned earlier also contributes to flexibility, allowing for easy reconfiguration or expansion of the structure.

Designing adaptable and flexible structures lets engineers create versatile solutions that can efficiently respond to changing requirements, environmental challenges, or user needs, maximizing the usefulness and value of the structure in harsh environments.

5. Occupant Comfort

Finally, considering the human factor when designing structures for harsh environments is essential. Prolonged exposure to extreme conditions can adversely affect a person’s physical and mental well-being. 

Consequently, the design must address thermal comfort, air quality, and noise control to create a suitable living and working environment.

Some strategies to improve occupant comfort include:

  • Efficient HVAC systems: Install well-designed heating, ventilation, and air conditioning systems to maintain a comfortable indoor temperature and ensure proper air circulation.
  • Acoustic insulation: Incorporate sound-absorbing materials and implement noise control measures to reduce the impact of disturbing sounds, such as high winds or heavy machinery, on occupants.
  • Ergonomic design: Consider the spacing of the interior layout, furniture, and equipment to improve the comfort and productivity of occupants.

Addressing occupant comfort in the design process ensures that structures in harsh environments provide a habitable and pleasant space, ultimately securing the well-being of the people residing or working within them.

Know The Essentials

Designing structures for harsh environments, including military shelter systems, requires a comprehensive understanding of the unique challenges and considerations involved. By concentrating on the factors above, engineers can create structures that are not only robust and resilient but also functional and comfortable.

Approaching the design process holistically and integrating various considerations helps create effective solutions. By doing so, engineers can ensure that their structures withstand the rigors of harsh environments while providing occupants with a safe and comfortable environment. Ultimately, this will lead to more successful projects and increased satisfaction among end-users.
