The architecture is a modern prefabricated and energy-s**ing yurt. The traditional yurt on the grassland is circular and the interior is not easy to be divided. In this design,our buildings use hexagonal honeycomb structure,with multiple monomers combined together to meet the needs of different plan types. It is convenient to assemble and s**es land.The exterior walls and wooden roofs are prefabricated in the workshop.So one-site casting operation can be greatly reduced. The three main materials are trombe wall,polycarbonate plkate and wood respectively. Trombe wall is an energy-s**ing material.In different seasons and time periods,control the switches of the upper and lower exhaust vents on PC and trombe wall,so as to store heat or promote ventilation.As a result,it’s warm in winter and cool in summer,which greatly s**es energy.It has low cost, no need for maintenance,large heat supply and small energy consumption,bringing fresh air to the rooms and improving the living environment of herdsmen.Polycarbonate sunlight board has high light transmittance,long life,and 250 times of impact strength than ordinary glass. Its mass is only half of glass, which can block ultr**iolet rays. It also has strong temperature adaptability.Wood is used on roofs and floors to @Create a warm atmosphere inside. Solar panels are installed on roofs to supply energy for the yurt while biogas provides energy for water heater and stove.The building is self-sufficient in energy and sustainable.
