My comment:
(a) The report cites
Wang Qian, Short-lived buildings create huge waste. China Daily, Apr. 6,
2010.

Quote:
"Industry sources have added to the mix by stating that the per unit energy
consumption of China's short- lived residential buildings is two or three
times that of residential buildings in developed nations.
"In China, construction waste comprises 30 to 40 percent of the total urban
waste. The construction of a 10,000-sq-m building will create 500 to 600
tons of waste, while the demolition of a 10,000-sq-m old building will
create 7,000 to 12,000 tons of waste, according to industrial data.
"Compared to the less than 30-year average life expectancy of China's
buildings, the average life span of a building in Britain is capable of 132
years and in the United States it is 74 years.
(b) It is hard for me to believe that a new building in China lasts just 30
years.
(i) What happens after thirty years? So many Chinese talk about seventy
years, the duration of use permit!
(ii) In New England where there is no quake or hurricane, Americans largely
build two- or three-storied house with wood and insulation, both of which
are treated with fire retardants.
