Low-carbon hotel: the focus of low-carbon hotel.

1. Carbon emissions of hotels as buildings

In the whole life cycle, green buildings can save resources (energy, land, water and materials), protect the environment and reduce pollution. China's newly started building area is half of the world's, and 80% to 90% of it does not meet the international energy-saving standards. China's heating energy consumption per unit building area is three times that of developed countries, and the building energy consumption standard is 75 watts per square meter, while the current limit standard in Europe is 25 watts. According to the statistics of the Ministry of Construction, in 2008, the building energy consumption accounted for 28% of the national energy consumption, and the building heat loss was 40% for windows, 40% ~ 50% for glass windows and 0/0% for roofs.

2. Carbon emissions of hotel energy

Hotels need to consume a lot of resources and emit a lot of air pollutants at the same time, which has become the urban pollution source of carbon emissions. For example, coal-fired and oil-fired boilers emit a lot of smoke, sulfur dioxide, nitrogen and hydrogen compounds and carbon dioxide. A medium-sized three-star hotel consumes about 1.400 tons of coal energy a year, and can emit at least 4,200 tons of carbon dioxide, 70 tons of smoke and dust and 28 tons of sulfur dioxide into the air. A hotel with a building area of 80,000 to10.8 million square meters consumes about10.3 million tons of standard coal throughout the year. The hotel energy expenditure accounts for 8% to 15% of the operating expenses.
