China Energy Consumption Overview

Among its many environmental challenges, China faces an enormous increase in energy consumption by buildings over the coming decades. Bricks and mortar already account for 25% of China’s total primary jaw crusher energy consumption, but are currently consuming energy at a very low level compared to developed countries. In fact, Chinese urban buildings consume three times less energy per unit of floor area, and 10 times less energy per person than those in the United States.

By examining the historical trajectory of building energy consumption in developed countries like the United States and Japan, we can find clues to what lies ahead for China. As per capita GDP rises, building energy usage intensity (EUI) – a measurement of the amount of energy used per unit of floor area – also increases.

China’s EUI is currently the same as Japan’s was in the 1960s and America’s in the 1950s. Since then, advances in heating and cooling technology have transformed how buildings are designed and operated. Along with the changes in lifestyles and consumption habits that have come with rising incomes, this transformation has led both the United States and Japan to double their building EUI. Unless this shift in design mode can be slowed or prevented, China can be expected to see a similar surge.

Most western architects and engineers are surprised that China’s buildings consume such a small amount of energy. In general, Chinese buildings have less insulation, leakier skin and windows and less advanced and efficient heating and cooling technology than their counterparts in developed countries. But they still manage to consume much less energy. Why? The explanation for this paradox lies in two interrelated factors: lifestyle and system design. Understanding how the combination of these factors drives increased energy consumption is critical to preventing a future boom in the amount of energy used by Chinese buildings. raw material mill:
