Abstract: This paper studies the external wall energy conservation construction technology of campus buildings under the premise of considering the energy consumption quota limitation. Firstly, it analyses the exterior wall structure system of campus buildings, analyses the influencing factors of structure system selection, and calculates the ultra-low energy consumption of campus buildings; Secondly, the steady-state calculation method is used to estimate the internal surface temperature at the corner of the external wall of the school building, and the energy-saving structure of the external wall of the school building is realised by considering the restriction. According to the wall design requirements of campus building exterior wall, the corresponding evaluation indexes are determined, and the reasonable evaluation results of campus building exterior wall energy conservation are selected. The energy-saving performance of the proposed method is verified by the condensation in summer and the accuracy of energy-saving control of campus building exterior wall.

Keywords: energy consumption quota; external wall energy conservation; campus architecture; condensation in summer; system selection.
