How to save electricity in hotels?

There are two ways for hotels to save energy and reduce emissions.

1, save power. Reduce unnecessary electrical equipment. (Zero investment, but it will lower the service standard and affect the hotel image)

2. Formulate an energy-saving scheme, adopt high-efficiency mechanical and electrical equipment, and reasonably control the operation of mechanical and electrical equipment through the building intelligent management system. (Guarantee the original service quality of the hotel, but need to invest a lot of money for maintenance)
