1. Project Introduction<o:p></o:p>

This project belongs to the technical field of protection and repair of ancient buildings and energy-saving renovation of ventilation and air-conditioning buildings. Regarding the reliability testing and identification of excellent historical protected buildings in service and energy-saving renovation of buildings, the project team carried out a project based on the existing state testing data of the original masonry materials of historical building brick structures and the concept that energy-saving renovation is compatible with the original style of historical buildings. Safety, durability, and applicability testing and identification of brick structure historical buildings, as well as key and common technology research on building energy-saving equipment, new methods, new materials and new devices.<o:p></o:p>

2. Cooperation content<o:p></o:p>

The innovative results achieved are as follows:<o:p></o:p>

1A safety appraisal method based on the current status of brick structure historical buildings was created, and a durability evaluation and residual service life calculation method that conforms to the time-changing rule of bricks used in historical buildings was proposed. From a new perspective of protecting the original appearance of the building, a method for evaluating the applicability of historical buildings with cultural value attributes as an important influencing factor has established a reliability testing and appraisal model and quantitative control indicators suitable for brick structure historical buildings.<o:p></o:p>

2It solved the technical problem of the contradiction between the reliability identification and energy-saving renovation of brick historical buildings and the current specifications and standards, achieved the goal of adapting the energy-saving renovation of buildings to the style of historical buildings, and successfully integrated ground source heat pumps and solar heat collection and energy-saving devices with the original appearance and style of historical buildings, developed a new polymer perlite insulation mortar material, and developed a core technology for energy-saving renovation of sprayed polymer insulation mortar suitable for internal insulation of external walls of historical buildings.<o:p></o:p>

3. Invented a new dynamic testing method for accelerating brick weathering using wind tunnels, ultrasonic testing of the thermal conductivity of energy-saving insulation materials and soil thermal response of ground source heat pumps, as well as a new equipment for thermal insulation with overheating and sunshade protection vacuum tube solar heat collector and its heat pipe solution regenerator, developed a new device for dynamic testing of the insulation performance of variable size flat roof and building walls for directly testing the resistance of thick walls of historical buildings, as well as a new process for spraying mortar with small machines with mixing function.<o:p></o:p>
