In Asia, the urban population is growing by 44 m people annually. The rapidly proceeding urbanization is an enormous challenge for the urban supply infrastructure and their operators. Especially in the sectors water and sanitary supply, energy supply and efficiency as well as land use and food security a critical state is already reached in many cities in Asia today. Cities and municipal providers in Asia are usually planning and managing sectoral and not integrated. Thereby, interrelations between the three “Nexus-sectors” (water, energy, food security) and the associated potentials and synergies in providing water, energy and food are not used adequately in practice. The aim of the project is to present and spread innovative concepts for the building sector.

The project is promoting the practical implementation of planning and management approaches for an integrated, urban resource management for the sectors energy, water and food security in Southeast Asian cities. Thereby, the project is contributing to a more future oriented and sustainable urban development.

The aim of the project in this context is capacity building (institutional and staff) for an integrated urban resource management in selected Asian cities. The focus is in buildings in Bangkok/ Thailand and the possibilities to reduce the energy demand and increase the usage of renewable energies.

For this the climatic as well as regulatory conditions are analyzed and rated. Part of the assessment is i. a. the analysis of legal/normative specifications and the transfer of know how and experience from Germany/Europe to Thailand. Furthermore, traditional and new building design and supply concepts are evaluated and enhanced. The goal is the development of design concepts which minimize the energy demand (especially for (air-) conditioning), allow the on-site usage of renewable energies and can be implemented in a cost-effective way. The results are presented to and discussed with relevant public and commercial/industrial stakeholders in several workshops. In a second step, a pre-design for demonstration (nearly) zero-energy building in Thailand will be developed in additional workshops. The interdisciplinary participants pre-design the building and thereby prepare the final design and construction of the demonstration building.
