Abstract

Improper implementation of energy efficiency policy exist and caught concerns on how should energy policies go beyond energy efficiency. The problem this study is trying to discuss it the limitation of energy efficiency policy in energy consuming sector, specifically building sector.

This study gathered several practices of energy efficiency policies in China’s building sector and analyzed the target design, implementation and actual effect of these policies, including building energy efficiency standard/code, green building labeling, and incentives to energy efficient home appliance and lighting bulbs, solar water heater and so on. Through analytical evidence, reasons of limitation of energy efficiency policies in building sector is deeply dug and concluded. Experience from China’s building sector is finally given as a policy reference to step out dilemma and achieved energy consumption and emission reduction.

By large scale of building energy information survey and case study on typical buildings, reasons for failures of these policies are concluded and summarized as two: one is unsuitable utilization of high efficient technology, such as very low-load ratio, or unnecessary system circulation and heat dissipation; the second is demand boost caused by energy efficient system and rebound effect of demand by energy efficiency policies, or rebound effect The essential reason is, product of building sector, indoor service, is not standard and uniformed as industry sector. Therefore, the solution to step out dilemma is move policy target from process control to outcome management, from energy efficiency of system while operation to result of final energy consumption. The experience from China’s building sector is to switch building energy policy from energy efficiency standard, energy efficiency product, to energy consumption quota(standard) and conduct energy consumption management.
