Cambodia has been experiencing significant urbanization, economic and population growth over the last decade with projections showing that this trend will continue until 2035 and beyond (United Nations, Department of Economic and Social Affairs, Population Division 2015). Moreover buildings are responsible for one third of the total final energy co...
Transition governance approaches for the building sector have been discussed for more than a decade. Very little work has however moved beyond the socio-political contexts of the Global North to scrutinize the spatial-institutional challenges of sustainability transitions in the Global South, or more illiberal contexts. Consequently, this paper int...
Building performance simulation has been commonly used for performance-based building design. However, the simulation accuracy is closely related to the model and input parameters regarding the building physics and occupant behaviour. To check and improve the accuracy of the simulation, the model usually needs to be calibrated using measured data....
Building performance simulations are particularly important for the development of various building energy efficiency strategies. However, the accuracy of these building simulations is often greatly influenced by real occupant behaviour, which leads to deviations between expected and measured performance. The occupant behaviour varies greatly from...
Vietnam is undergoing a continuing construction boom. This enormous volume of new constructions is characterized by simple building techniques and large consumption of materials. The Vietnamese government would like to reduce the use of traditional fired clay bricks to avoid inefficient brick production with high energy use, significant CO2 emissio...

As a result of the rapid economic development in Vietnam, lifestyles and the needs of residents have been changing in new building typologies. Materials, constructions, and supply systems that were not previously common, are now used. This development leads to far-reaching issues with structures and building physics, especially under the demanding...
Although microclimate effects of the urban fabric and the urban green are known, they are rarely considered in energy performance studies of buildings in their specific context. The microclimate in the urban environment is effective on human well-being and on the energy demand of buildings. Especially the temperatures surrounding buildings in summe...
China's building stock of more or less uniform residential blocks requires energy-, comfort and not at least architectural upgrade, if future demands are to be met and if demolition and thereby loss of valuable resources is to be prevented. Replacement of these buildings is not an option since affordable housing continues to be required in Chinese...

Whether a building can be recycled or not, does not only depend on the selection of materials, but also on the joints and connections between the material layers and the building elements. If materials can be separated in specific material groups or if connected materials do not compromise each other in quality, recycling is possible. In buildings,...
Worldwide there exist several well-known "Sustainable Building" or "Green Building" certification systems, while the comparison of different systems and their international application are of great research interests.

Questions
Question (1)
We have climate data metered 4 times per day (1, 7, 13, 19h) at a weather station and need to produce hourly climate datasets for annual simulation studies. - Does anyone know how to do this best? Since we need to include related wind and rain data for hygrothermal simulations simply filling the gaps might not work. Does anyone have an idea? I would be thankful for a hint.
