The invention relates to an equivalent space construction technology of a full transparent louvre glass double-layer breathing curtain wall. The construction technology includes the following steps: measurement and setting-out, equivalent space positioning and division, installation and adjustment of a positioning and division main part connecting seat, stratification of equivalent space area, positioning of point, line, surface and chord angle, preparation, installation and debugging of primary and secondary keel of the division and stratification parts, comprehensive retesting of positioningpoints, customization of stainless steel standard fixture, installation of different parts of the stainless steel with the stainless steel fixture step by step, unified test and adjustment by fixed ruler fixtures, installation of the layered louvre glass, and fixation of the angle and position of the layered louvre glass. The construction technology solves the problem of difficult implementationof precise division in the construction of the equivalent space of the full transparent louvre glass double-layer breathing curtain wall, provides the basis and method for the application of the equivalent space of the full transparent louvre glass double-layer breathing curtain wall, provides the data for the efficiency of the air flow ventilation in the breathing curtain wall, and provides the basis for efficient energy conservation.
