Resilience
Contents |
[edit] Introduction
Resilience is the ability to adapt and respond to changing conditions while maintaining functionality.
Resilience to climate change, involves adaptation to possible impacts such as; intense storms, greater precipitation, increased flooding, longer and more severe droughts, melting permafrost, wildfires, warmer temperatures, more power outages, and so on.
The SuDS Manual published by CIRIA in 2015 defines climate resilience as: ‘The capacity of a system to cope with a hazardous climate event or trend or disturbance, responding or reorganising in ways that maintain (or recover) its essential function, identity and structure, while also maintaining the capacity for adaptation.’
'Encouraging resilient assets using BREEAM' defines resilience as ‘the capacity of built assets and infrastructure to endure acute shocks and chronic stresses while successfully adapting to long-term changes’.
In terms of the built environment, resilience can involve refining designs, stress testing solutions, designing adaptable and flexible structures, developing 'stronger' infrastructure and so on.
[edit] Principles of resilience
Resilience measures should be discussed and incorporated during the predevelopment and planning stages:
- Identifying hazards.
- Assessing vulnerabilities.
- Analysing scenarios and impacts.
- Establishing performance targets.
- Assessing how resilient interventions can create value in terms of underwriting building operations and mitigating harm.
- Balancing costs and long-term value over the intended service life.
- Developing lines of communication about potential hazards to build resilience between owners, operators and users.
[edit] Resilient design
[edit] Buildings
Resilient design strategies for buildings include:
- Designing and building structures that can accommodate the anticipated impacts of change.
- Strengthening critical systems to withstand extreme weather.
- Using future climatic conditions to model design solutions rather than relying on past data.
- Designing structures that will remain habitable in the event of power or energy loss.
- Building in manual overrides to reduce dependence on complex building controls and systems.
- Optimising on-site renewable energy supply.
- Rainwater harvesting.
- Composting toilets and water-less urinals.
- Selecting materials and components that will not present a hazard in the event of damage.
- Combining tested vernacular design practices with modern materials and techniques.
[edit] Community
Resilient design strategies at the community scale include:
- Building social structures that strengthen the community, such as gathering spaces, communal gardens, and so on.
- Minimising reliance on fuels sourced from a distance.
- Reducing the urban heat island effect
- Managing stormwater.
- Designing resilience into communications infrastructure.
- Encouraging community education programmes to instil greater understanding.
[edit] Regions and ecosystems
Resilient design strategies at the regional and ecosystem scales include:
- Maintaining and protect aquifers.
- Developing and strengthening regional transport networks.
- Developing regional renewable power-generation systems.
- Encouraging reliance on regionally-manufactured goods.
[edit] Security
The Loss Prevention Standard (LSP 2082 : Issue 1.0), published by BRE Global in 2017, defines resilience as the: ‘Ability to maintain and adapt in response to changing circumstances, including changes in security threat, facility operations, maintenance and sub-system failures.’
[edit] Flood resilience
The National Flood and Coastal Erosion Risk Management Strategy for England, Glossary, published by the Environment Agency in 2020, defines resilience as: ‘The capacity of people and places to plan for, better protect, respond to, and to recover from flooding and coastal change. Places can achieve this by: making the best land use and development choices, better protecting people and places, responding to and recovering from flooding and coastal change whilst all the time adapting to climate change.’
