Description
Technical Field

Background
As a big country with rapid economic development, China has increasingly demanded energy, and particularly in recent years, the contradiction between economic growth and energy constraint becomes more and more prominent, and "energy conservation" becomes the urgent priority of national economic development in China. The building energy consumption accounts for a large proportion of the total energy consumption of our society and is on the trend of increasing year by year, so the building energy saving is one of the key points of our energy saving work. A large number of new energy-saving buildings are built every year in China, the energy-saving buildings are generally built according to the requirements of national and local building energy-saving design standards, and special assessment is needed if the buildings meet the requirements of the energy-saving standards. The assessment of building energy saving cannot be based on design solutions, and actual field tests should be performed. At present, a series of energy-saving detection standards are successively issued by countries and places, such as 'heating residential building energy-saving detection standard' (JGJ132-2001), 'residential building energy-saving on-site detection standard (heating residential building part)' in Beijing City (DBJ/T01-44-2000), and 'residential building energy-saving detection evaluation standard' (DG/TJ 08-801) 2004) in Shanghai city. There are many indexes for energy saving of buildings, and the heat transfer coefficient of the enclosure wall is one of important indexes. The existing wall heat insulation performance detection device needs manual long-term watching and reading, so that manpower is consumed, and detection precision is also easily affected by various errors, so that the detection result is not accurate.
