The core of building energy conservation and thermal insulation lies in employing technical measures to reduce heat loss from structures, enhance energy utilization efficiency, and simultaneously ensure indoor comfort. The following provides a detailed analysis:
Energy-Saving Effects
Reduced Energy Consumption: Exterior wall insulation can decrease winter heating energy consumption by 40%-50% and reduce summer air conditioning energy consumption by over 30%.
Carbon Emissions Reduction: Each kilogram of standard coal saved equates to 781 kilograms of CO₂ emissions avoided.
Insulation Technology Classification
Exterior Wall Insulation: Mainstream techniques include thin-coat plastering over bonded insulation boards and external insulation with insulating mortar. New integrated insulation structures offer Class A fire resistance.
Roof Insulation: Recommended materials include graphite polystyrene boards, extruded polystyrene boards, or vacuum insulation panels, with a suggested thickness of 15-25 cm.
Window Optimization: Utilize triple-pane double-cavity insulated glass (U-value 0.8-1.4) paired with shading devices to balance seasonal demands.
