JENGA aims at academic capacity building and knowledge transfer for energy efficiency and low-carbon technologies in the field of sustainable housing, addressing the fact that the building sector accounts for 40 % of global energy consumption and 30 % of greenhouse gas emissions. By introducing the method of problem-based learning through the implementation of 3 major, practice oriented design-build courses in Kenya, Uganda and Rwanda into existing curricula of architecture, links will be established between content and method of teaching and also between the participating institutions themselves. This will culminate in the creation of a regional network of excellence for thinking, teaching, researching and producing energy-efficient housing. Co-operation will strengthen teaching and knowledge management competencies including student centred problem-based learning. Low cost, low-carbon, energy-efficient and sustainable construction technologies, as well as the skills and methods to teach them, will help to meet the energy demand.
