In order to explore the energy consumption characteristics and consumption technical routes in the nearly zero-energy consumption public building in the summer cold area

model selects a nearly zero- energy- consuming office building in Wenzhou as the research object

uses eQUEST building energy consumption simulation software and relevant provisions in the national standard GB/T51350. First of all

it stipulates that the energy consumption simulation of the project and design building of the project yearly

analyzes its energy consumption composition and energy consumption characteristics. Then it studies the largest outer window load

electricity composition and consumption technology path in winter and summer. Finally

it calculates the level of carbon emissions

the energy saving rate of the body

the comprehensive energy saving rate and the utilization of renewable energy

through the above channels

and achieves the design goals of the nearly zero energy consumption building of the project

also judges the carbon emission level of the building. The results of the research energy-saving professionals selects the technical route reasonably

and provides reference suggestions for the design of nearly zero energy consumption public buildings.
