Energy saving technology of wall insulation of harbor building based on energy cost analysis

Seaport buildings have been affected by marine moisture for a long time, but most of the wall thermal insulation studies not considered transfer effect structure. Therefore, considering function structure and energy consumption solar radiation, based on cost analysis, paper puts forward research energy-saving technology harbor building analysis. Grey clustering is used to analyze project environmental benefits determine index weight. By using two kinds materials three positions, performance condensation characteristics are analyzed. It found that increasing thickness layer conducive reducing heat loss wall. Extruded polystyrene foam (XPS) material better than expandable board (EPS) material, while EPS more economical XPS.
