A trend to go energy efficient among buildings
According to electrical experts, an upgrade of the air conditioner system (usually consumes from 60% to 80% electricity of the buildings) in old buildings could help save a quarter of power consumption. In 2009, Caravelle Hotel saved over 500,000 kWh, equivalent to nearly 1.5 billion dong and cut down over 350 thousand kilograms of carbon dioxide emission by using energy saving bulbs and resetting temperature, installing energy saving device for boilers.
