The invention relates to the field of building engineering designs, in particular relates to a method for paving an integral energy-saving roof of a railroad platform. The method is characterized by at least comprising the following steps of: pre-arranging vertical posts on a platform, assembling roof panels, paving the assembled roof panels on the vertical posts in a large span, and finally loading inner electric pipelines. According to the method for paving the integral energy-saving roof of the railroad platform, disclosed by the invention, the large-span pavement can be realized, the quantity of roof envelope structure bodies is reduced, the costs of materials and construction are reduced, and the construction period is shortened; the integration of electric (light illumination, station broadcast) pipelines in a roof system is realized, the roof system is ensured to be simple and brief, and the appearance of a building is ensured to be attractive; in addition, a supporting position for mounting a solar system is reserved so that a solar photovoltaic power generation system can be additionally arranged as required, thus the railroad platform is green, low-carbon and energy-saving, and environmental-friendly.
