The whole process engineering consulting business is a hot topic in the field of domestic engineering construction in recent years.The whole process engineering consulting of construction project implementation can integrate management fragments,break the barriers between engineering stages,improve the efficiency of project management and effectively reduce the cost of engineering construction."1+N"mode is a new service mode provided by the whole process engineering consulting unit."1"refers to the whole process project management,which is the core of project management,and"N"refers to professional consulting,which is the sub-item of project management.Taking an air conditioning cold and heat source retrofitting project in Shanghai as an example,this paper focuses on how to carry out the project management of mechanical and electrical retrofit of large public buildings under the whole-process engineering consulting model of"1+N".Practice has proved that the project management mode can shorten the construction period,improve efficiency,reduce carbon emission and achieve considerable energy saving benefits under the premise of ensuring system safety,reliability and technical economy.
