Air Conditioning at Empty Lift Lobbies in Some Buildings or Malls in Hong Kong are Cooler than Necessary.

Ever wonder why our weather gets hotter year after year? We all know that there are so many factors contribute to the hot weather. Let’s cite one everyday example, just stop over at any empty lift lobby in those air conditioned buildings or malls in Hong Kong for a minute and you will get a clue.

Most residents seldom stay in the lift lobby for more than 2 minutes, yet most air-conditioned lobbies in Hong Kong are maintaining at a temperature much lower than are necessary. We are talking about 24 hours a day, 7 days a week continually for decades. Try to multiply the figure and anyone would know that’s a lot of waste not only in terms of Hong Kong dollar, but also in kilowatt in terms of power consumption, and not to mention in terms of excess CO2 emission. The heat generated by the air conditioning unit also adds up to the already high outdoor temperature.

Being constantly suffered from the non-stop exhaust air from the air conditioned from those empty lift lobbies, the residents in lower floors had no choice except to switch on their air conditioner as well in respond to the heat generated by the lift lobby air conditioning. This in turn creates a vicious cycle for every body to switch on their air conditioning units just because air conditioning in the empty lift lobbies is cooler than necessary. Could anyone from those building management comes out and explain why it is necessary for the air conditioning in the empty lift lobby to maintain at low temperature after midnight till dawn.

While the government has been promoting turning off car engines while idling on the street, I wonder why there is no regulation controlling the excessive air conditioning in empty lift lobbies. In fact other responsible companies have already been risen their office temperature to 25C Celsius, shouldn’t empty lift lobbies be kept that cool all the time.

While everyone is concerning for our environment, I don’t see how the excessive low temperature in the empty lift lobby fits into any of the theme of promoting a greener Hong Kong.

I am quite surprised to see no one in Hong kong has ever noticed this problem before and no one has ever complained about this problem until today.
