The gas-fired distributed systems have been proven to maximize energy efficiency from high to low. Focusing on the perspective of users and combining the energy use characteristics of a five-star hotel in China

this paper proposes a simple and efficient innovative energy solution of gas distributed + energy storage battery which can complement each other.The primary energy efficiency of the gas distributed energy system is more than 80%

which can reduce the operating cost of the hotel. The annual average energy saving cost is more than 15%

and the incremental recovery period of equipment investment is just about 4 years. It also can be used to apply for green and energy-saving buildings and apply for government-led work conferences. At present

domestic hotels adopt distributed energy system to solve their energy supply problems

which has become a new trend.
