英文摘要	Sri Lanka, like many other developing countries in South Asia, experiences severe heatwaves that affect the health and livelihoods of hundreds of thousands of residents. The risk to heat exposure will be further exacerbated when 1) the heatwave coincides with urban heat island in the urban area in a non-linear manner; 2) there exists a 'cascading/concurrent' heat hazard indoors as the majority of the households in Sri Lanka have no access to air conditioning and people spend the majority of their time indoors. Living in such hot-humid climate for many generations, Sri Lankan people have established the unique and remarkable climatic, historical, cultural and architectural values and knowledge to be resilient to the extreme climate, reflected in the unique vernacular architectural and urban design. However, with rapid urbanization and economic development, the traditional Sri Lankan vernacular villages and dwellings are being replaced by fast-built, western-style brick-concrete structures. The indigenous Sri Lankan climate-sensitive design knowledge is being forgotten and disappearing. In the developed countries, it has been proved that new data streams, improved forecasts and better visualization techniques have the potential to improve the utility of predictions for early warning of adverse conditions. However, for the countries in the global south (e.g. Sri Lanka), it is vital to provide such climate services with embedded indigenous design knowledge and use of local resources to improve the resilience to extreme humanitarian disaster. COSMA is a multidisciplinary study that will bring together a group of experts in urban meteorology, building environmental engineering, architecture, urban planning and social science, to work with local stakeholders to deliver SHEAR programme objectives. At the heart of the project are the studies of: 1) how the heatwave overheating risk prediction and assessment could be improved at finer urban and building scales; 2) what are the useful indigenous design knowledge in Sri Lanka to mitigate heatwaves, and how they could be regenerated and re-incorporated into the heatwave action plan and future design practice? COSMA aims to develop an integrated modeling approach by taking into account the urban heat island, building characteristics and vulnerable population to build effective early warning system and city-scale heat action plan. By closely working with local community, government and professionals, one important goal of COSMA project is to harvest and regenerate traditional design knowledge (both building and urban scales) from indigenous craftsmen embedded within local culture and traditions, and feed into the heat-exposure risk mitigation plan. The final outputs of the project will be a series of hierarchical overheating risk and mitigation potential maps across different scales for Colombo, Sri Lanka. COSMA, led by the University of Reading (UoR), involves collaborations with Glasgow Caledonian University (GCU), and carried out in partnership with a group of well-established Sri Lankan partners-Department of Meteorology (DoM) and the Institute of Town Planners Sri Lanka(ITPSL) as well as researchers at University of Moratuwa (UoM).
