Analysis and design of near-zero energy building for Mountain News Center

The design difficulties of realizing near-zero energy consumption in this project are analysed, and the energy-saving technologies applied to the building and the HVAC system to achieve near-zero energy consumption are presented. The annual operating energy consumption and energy-saving rate of the project are simulated and calculated. The results show that compared with the standard building, the annual heating energy consumption is reduced by 51%, the air conditioning energy consumption is reduced by 26.4%, and the building energy-saving rate is 35.6%.
