Green and energy efficient HVAC system design for Guangzhou White Swan Hotel retrofitting project

Presents the design idea of the green and energy-saving retrofit. As an existing hotel building with high energy-consumption problem, analyses the actual benefits of green energy-saving measures. Selects the HVAC system, domestic hot water system, boiler room system and energy management system as the key contents of the retrofit. The project reaches a two-star level in the green building design assessment. Concludes that the annual energy cost will decrease by more than 100 yuan per square meter at the same energy intensity and the incremental payback period is less than 3 years.
