[0002] Common temporary facilities are a new concept of environmentally friendly and economical mobile houses with sandwich panels as the enclosure structure and standard modular series for space combination. They have the advantages of serial development, integrated production, supporting supply, inventory and multiple turnover. As a mobile and portable temporary facility, mobile houses have the disadvantages of poor insulation and thermal insulation, resulting in cold in winter, hot in summer, and high air conditioning energy consumption.
