This document addresses adaptation to climate change in the design of buildings and civil engineering works. The document provides a framework, principles, and specific guidance for resilience design adaptive to climate change (RDACC) in buildings and civil engineering works. This type of design method will be applicable not only to new construction, but also to the renewal, retrofit, and replacement of buildings or civil engineering works. This document does not address: — adaptation to climate change in the production and procurement of building materials, components and devices; — adaptation to climate change in construction processes; — climate change mitigation in buildings and civil engineering works; — emergency management in buildings and civil engineering works.

Introduction
Adaptation to climate change has become an urgent need globally. According to the United Nations
Environment Programme (UNEP)'s Adaptation Gap Report 2022, "the world must urgently increase efforts
to adapt to the impacts of climate change that are already here and to those that are to come".
In the context of global climate change, buildings and civil engineering works with service lives of decades
or even centuries will face new climate challenges. These challenges include the increase of frequency and
intensity in extreme weather events such as heatwaves, wildfires and floods, as well as chronic changes such
as sea level rise. This can result in increase of vulnerability in built assets designed based on the climate
of the past decades, risking human health and well-being, and causing economic loss and social impacts.
Therefore, adaptation to climate change in buildings and civil engineering works should be considered in a
timely manner.
This document provides a design approach called the resilience design adaptive to climate change (RDACC),
which offers specific guidance on how to produce buildings and civil engineering works with climate change
resilience. It is a method for adaptation to climate change at the engineering level.
The typical actions of RDACC include:
— identifying changes in climatic impact-drivers;
— identifying resilience limits and decision making on strategies;
— monitoring and optimization;
— decommissioning.
This document is useful to stakeholders including asset owners and users, investors, authorities, standards
developers, meteorologists, engineers, architects, manufacturers, builders, and other parties involved in
the RDACC.
