“…Gers can be easily assembled and disassembled by two to four adults within a few hours. According to a questionnaire survey conducted by Purev and Hagishima [10], most people living in urban gers partially reassemble their gers approximately twice a year in order to dry the felt sheets, to add more felt sheets, or to improve the airtightness between various components for severe winters. The interior space of most gers can be classified into several functional zones by furniture, and the layout of furniture is relatively similar among households.…”

In this study, the walls and roofs of five-walled gers were insulated with high-performance building insulation materials while maintaining the original purpose of portable design of the ger. The ger is a traditional nomadic housing made of wooden structures and covered with few layers of felt sheets. In Ulaanbaatar, 30.4% of the total households live in gers. The indoor air temperature, surface temperature, outdoor air temperature, and solar radiation were measured to validate the performance of roof and wall retrofitting. Measurements were performed in two phases: before and after renovation. After renovation, the wall surface temperature increased and became similar to the roof surface temperature. The floor surface temperature remained low, from 0 °C to 15 °C, indicating that floor insulation was needed. The operative temperature was up to 5 °C higher than the indoor air temperature before renovation, and after renovation, the operative temperature become 1.5 °C higher than the indoor air temperature owing to the use of an electric heating device.

“…With this background, the authors conducted a series of field surveys on the design of existing urban gers, people's lifestyles and interest in improving their living environment, and the indoor thermal environment 5) . In this paper, we propose a thermal insulation retrofitting method tailored to urban gers based on the results of the field surveys.…”

This paper presents an insulation retrofitting method developed for nomadic mobile housing called ger , which is used by urban residents in Ulaanbaatar, Mongolia, to promote the shift from coal stoves to electric heating devices to reduce air pollution. Field surveys of current gers were conducted to ensure that the design and materials chosen were affordable with high market availability. The developed system was installed in a typical urban ger in winter to obtain feedback from residents and local stakeholders. The results of field measurements of indoor thermal conditions of a ger with and without retrofitting are reported.

The purpose of this study is to analyze the effect of ratio composition and particle size on pelletization of various feedstocks. The feedstock materials were used leaves, wood, junk waste, shells of coconut and combination of any kind of pure feedstock materials with composition ratio 75:25, 50:50 and 25:75. The feedstocks with highest calorific value crushed and filtered using variation of mesh (20,40,60,80,100 and 120mesh) before pressing in mold dies diameter 6.5mm using multiple pellet press at 70kg/cm 2 . The results showed that combination with wood results higher calorific value of feedstock, and larger particle size impact lower durability and lower density.
