The One shopping mall in Tsim Sha Tsui denies it is the city's coldest mall and says its neighbours give shoppers a cooler welcome.
The South China Morning Post recorded temperatures as low as 21.3 degrees on the fourth floor of The One, well below the 24-to-26 degrees Celsius target set in a government-sponsored energy saving charter, to which 100 malls agreed last month. The One did not sign up.
The two higher floors of the mall also failed to meet the charter's target, with temperatures ranging between 21.4 and 23.6 degrees.
The One, developed by Chinese Estates Holdings, was the coldest among 25 malls surveyed by the Post - 18 of which agreed to the charter.
But the operator of the mall, which opened in 2010, insists that when it comes to the town's coldest malls - it is certainly not the one. It said its internal temperature record for the month showed the mall was at between 22 and 25 degrees.
The mall sent operatives to its local competitors, K11 and i-Square, to check out temperature readings. They found the average temperature at K11 was 23.1 degrees, and i-Square 23 degrees, both lower than The One's 23.6 degrees as measured by the mall operator.
