The improvement of energy efficiency in the building sector through the use of renewable raw materials from agroforestry systems

More than half of primary energy consumption in Uzbekistan is being spent on the energy supply for the building sector. Housing is one of the largest sources of CO2 emissions, chiefly due to heating during winters and cooling during summers. There is great need to increase efficiency though improved insulation of houses and to substitute carbon-intensive building materials with locally available bio-based resources. Based on locally adapted building design, materials, and improved production methods, the project develops resource-saving alternatives that combine both traditional and modern construction using wood, agricultural residues and clay. To demonstrate the advantages of such building systems it will build a model house in Tashkent. Educational materials will be developed that focus on the systemic relationships and synergetic benefits between agroforestry, ecosystem services, housing systems, energy efficiency and human well-being. These training modules will be included in the curricula of vocational and higher education. E-leaning contents will be made available for wider audiences in Central Asia.

Next to wood, agroforestry systems provide many other ecosystem services such as reduced wind speed and thus reduced water consumption of the agricultural systems, increased crop yields, and increased soil organic carbon contents in soils. The project provides economic perspectives for farmers as well as small scale wood processing in rural areas. Other synergies include lower consumption of coal and wood in heating due to better insulation. This reduces air pollution, which in Central Asia has detrimental effects on health.

Funding and Host Institutions

VEGERA is part of the International Climate Initiative (IKI). IKI is an important part of the German government international climate finance commitment. Since 2022, the Federal Ministry for Economic Affairs and Climate Action (BMWK) has been the lead ministry for the IKI. The funding program cooperates with its founding ministry, the Federal Ministry for Environment Nature Conservation, Nuclear Safety and Consumer Protection (BMUV), as well as the Federal Foreign Office. The team is hosted by the Centre for Econics and Ecosystem Management at the Eberswalde University for Sustainable Development (HNEE).
