Fu (2010)
From 2010 to 2050, China’s cumulative energy use in building new housing
space is shown in Fig. 1.8 (Fu 2010). Calculation of scenario S2, S3 and S4 finds that
curbing the growth of per capita housing space demand and prolonging the actual
service life of residential buildings would both slash increase of future energy use
from residential housing construction, and the energy saving from extending life of
residential buildings is even more promising. Besides residential houses, other fixed
assets could also cut energy waste by extending life of assets and upping capacity
utilization. These two approaches have become effective tools for energy use control.
The above research suggests that increasing utilization and service life of production capacity should be encouraged in China’s future economic and energy planning.
Besides, it’s vital to align energy needs with economic development. More attention
should be paid to the changes in the end consumption brought by economic development, as opposed to a sole focus on the current energy supply and efficiency, thereby
ensuring a precise match between energy supply and consumption, and reducing
construction energy waste.
