Research on the Application of Nearly Zero Energy Building Technologies in Large Office Buildings in Hot Summer and Warm Winter Regions——Taking China Overseas Building As An Example
With the rapid development of nearly zero energy buildings and the gradual maturity of technology,hot summer and warm winter areas have become a new direction for pilot and promotion of nearly zero energy buildings due to their high level and speed of economic development,high development intensity of large office buildings,and great energy-saving potential.This paper took the China Overseas Building as an example to study the application method and implementation path of nearly zero-energy technology for large office buildings in hot summer and warm winter regions,with performance-based design methods as the core,passive energy-saving design,efficient energy system energy-saving design,and full utilization of renewable energy as the main content.This provides a systematic approach for the development of this type of nearly zero-energy buildings,and provides a reference for similar projects.The study found that the highest contribution rate of energy conservation is achieved through the improvement of energy efficiency in the energy system,at 59.6%.From the perspective of technical measures,the technologies with the highest proportion of energy-saving contribution are high-efficiency cold and heat sources and high-efficiency lighting systems,with 26.2%and 19.7%respectively.
