How can you design buildings to be more resilient to sea level rise?

1 Assess the risks

The first step in designing buildings for sea level rise is to understand the current and projected conditions of the site. You need to collect and analyze data on the elevation, topography, hydrology, geology, and vegetation of the area, as well as the historical and future trends of sea level rise, storm surges, and extreme weather events. You can use tools such as digital elevation models, flood maps, and risk assessments to identify the potential hazards and vulnerabilities of the site and the building.

2 Choose the location

The location of the building is crucial for its resilience to sea level rise. Ideally, you should avoid building in areas that are prone to flooding, erosion, or subsidence, or that have low adaptive capacity. You should also consider the impacts of the building on the surrounding environment, such as its effects on natural drainage, groundwater, and ecosystems. If possible, you should select a site that is elevated, well-drained, and protected by natural features such as dunes, wetlands, or mangroves.

4 Waterproof the materials

Another important aspect of designing buildings for sea level rise is to choose materials that are waterproof, durable, and resistant to corrosion and decay. You should avoid materials that are porous, absorbent, or organic, such as wood, plaster, or carpet, as they can be damaged by water and mold. Instead, you should opt for materials that are impermeable, synthetic, or inorganic, such as concrete, steel, or plastic, as they can withstand moisture and salinity. You should also seal the gaps and openings in the building to prevent water infiltration.

5 Incorporate green features

A sustainable and resilient building should also incorporate green features that can reduce its environmental impact and enhance its adaptation to sea level rise. For example, you can use renewable energy sources, such as solar panels or wind turbines, to power the building and reduce its greenhouse gas emissions. You can also use rainwater harvesting, greywater recycling, or bioswales to manage the water supply and quality of the building. Moreover, you can use green roofs, walls, or gardens to improve the insulation, ventilation, and biodiversity of the building.

6 Engage the stakeholders

Finally, designing buildings for sea level rise is not only a technical challenge, but also a social and cultural one. You need to engage the stakeholders, such as the owners, users, managers, and regulators of the building, in the planning and decision-making process. You need to communicate the risks and benefits of the design, as well as the costs and trade-offs involved. You also need to consider the values, preferences, and needs of the stakeholders, and ensure that the design is acceptable, accessible, and adaptable to them.
