At the worldwide scale, both buildings and buildings construction sectors combined are responsible for 36% of global final energy consumption and nearly 40% of total direct and indirect CO2 emissions.
At the moment China is the biggest energy consumer in the world and the building energy use is the second largest right after the US with 16% of total final energy consumption in buildings globally (2012 consumption).
IEA stated “Globally, on average, buildings in 2040 could be nearly 40% more energy efficient than today”.
Policies and Measures for Buildings in China
To face this major environmental issue, China is moving fast by implementing multiple regulations related to the Building Energy Efficiency. As the building market in China is growing fast, it is applied to new construction but also for existing building where refurbishment plans become more and more common. Every part of a building must be taken into account, from the envelope to key HVAC equipment.
Some pilot Chinese province are subject to financial incentives to encourage energy efficiency measures for both new construction and renovation projects.
In concrete terms, the Ministry of Housing and Urban-Rural Development (MOHURD) is continuously improving the Chinese GB Code.
In 2014, The Notice of the General Office of the State Council on Printing and Distributing the Strategic Plan for Energy Development (2014-2020) (国务院办公厅关于印发能源发展战略行动计划（2014-2020年）的通知) had been published.
The main point in the building and industry sectors are the following ones:
The implementation of a higher national building energy efficiency standard will be accelerated, requiring a combined 75% improvement in energy efficiency compared to the building standards of the early 1980s. It is expected that in 2020, the green buildings will account for at least 50% of new buildings in the urban region.
The expansion of high-pollution and high energy-intensive industries is heavily restricted, alongside the phase-out of obsolete technologies and excess capacity.
We can also observe an evolution of the GB code becoming more and more restrictive and specific. For instance:
In place since 2018: GB 35971-2018 “Minimum allowable values of the energy efficiency and energy efficiency grades for hermetic motor-compressor in room air conditioners”
Which sets minimum allowable values of energy efficiency for compressors.
In place since 2017: GB 19577-2015 “Minimum allowable values of the energy efficiency and energy efficiency grades for water chillers”
Which sets minimum allowable values of energy efficiency for chillers.
In place since 2015: GB 26920.2-2015 “Minimum allowable values of energy efficiency and energy efficiency grades for commercial refrigerating appliances”
Which sets minimum allowable values of energy efficiency for refrigerating appliances.
In this context of global warming where building energy efficiency is one of the main issues, TERAO ASIA is trying to help clients and partner to be true driving force behind the energy transition by implementing smart and innovative solution.
