ENERGY- SAVING ROOF DESIGN OF RURAL NURSERY BUILDINGS IN HANDAN AREA

Having the specific engineering examples as a background,starting from architectural properties of nursery buildings,through one-dimensional steady heat transfer theory of architectural maintenance structure and other knowledge,combined with architectural structures and construction cost,various forms of energy-saving roofs were calculated. Which were also analyzed and compared. For the finally determined energy-saving roof scheme,it was done the investment recovery analysis. According to the results calculated by dynamic and static methods,it was fully validated the energy-saving superiorities of flat inversion type roof.
