“…Traditional biomass is widely used for 3 Because of reliability and consistency problems with the sectoral energy breakdown provided by China's National Bureau of Statistics, as pointed out by Sinton [9], we instead used IEA's energy balances to characterize China's residential and commercial building energy consumption in 2005 [1] 3 and used the China Energy Databook to split the residential energy consumption into urban and rural uses [2]. Regarding service-level energy consumption, due to the absence of comprehensive national energy consumption survey, we have applied reasoned judgments based on several detailed energy use analyses and local surveys [10][11][12][13].…”

“…We assumed that the price and income elasticities of the demand for a building are -0.4 and 0.4 for both urban residential and commercial building consumers and -0.15 and 0.15 for rural residential building occupants; and the price elasticities of the supply of building floorspace are set to 0.75 for both urban residential and commercial buildings and 1.0 for rural residential buildings. 11 These numbers are based on the general assumption that demands for urban residential and commercial buildings are more price-and income-responsive than that of rural residential buildings,…”

We present here a detailed, service-based model of China's building energy use, nested in the GCAM (Global Change Assessment Model) integrated assessment framework. Using the model, we explore longterm pathways of China's building energy use and identify opportunities of reducing greenhouse gas emissions. The inclusion of a structural model of building energy demands within an integrated assessment framework represents a major methodological advance. It allows for a structural understanding of the drivers of building energy consumption while simultaneously considering the other human and natural system interactions that influence changes in the global energy system and climate. We also explore a range of different scenarios to gain insights into how China's building sector might evolve and what the implications might be for improved building energy technology and carbon policies. The analysis suggests that China's building energy growth will not wane anytime soon, although technology improvement will put downward pressure on this growth. Also, regardless of the scenarios represented, the growth will involve the continued, rapid electrification of the buildings sector throughout the century, and this transition will be accelerated by the implementation of carbon policy.

“…In China, HVAC systems for typical existing construction tend to be distributed, not centralized [19,20] and for new, low-energy building design, innovative heating and cooling strategies will tend to rely more on distributed hydraulic, perimeter zone solutions. For example, two-or four-pipe fan coil unit (FCU) systems with centralized outdoor air unit are more popular than variable-air-volume (VAV) systems.…”

Assessment of the Potential to Achieve very Low Energy Use in Public Buildings in China with Advanced Window and Shading Systems

et al. 2015

As rapid growth in the construction industry continues to occur in China, the increased demand for a higher standard living is driving significant growth in energy use and demand across the country. Building codes and standards have been implemented to head off this trend, tightening prescriptive requirements for fenestration component measures using methods similar to the U.S. model energy code American Society of Heating, Refrigerating and AirConditioning Engineers (ASHRAE) 90.1. The objective of this study is to (a) provide an overview of applicable code requirements and current efforts within China to enable characterization and comparison of window and shading products, and (b) quantify the load reduction and energy savings potential of several key advanced window and shading systems, given the divergent views on how space conditioning requirements will be met in the future. System-level heating and cooling loads and energy use performance were evaluated for a code-compliant large office building using the EnergyPlus building energy simulation program. Commercially-available, highly-insulating,

“…Energy consumption of urban office buildings in China is about 33.6-107 kWh/(m 2 ·a), while the average energy consumption of commercial buildings is 55 kWh/(m 2 ·a) [4]. Due to the remarkable energy-saving potential, many studies [5][6][7][8][9] have focused on the energy-saving evaluation of public buildings. As an important and special branch of public buildings, traffic transportation buildings like railway stations have characteristics of large space span, various functions, high density of people, and long operation time of air conditioning system.…”

In recent years, the energy performance of public buildings has attracted substantial attention due to the significant energy-saving potential. As a semi-open high-space building, the high-speed railway station is obviously different from other public buildings and even traditional stations in terms of energy consumption and internal environment. This paper investigates the current energy consumption situation and environmental quality of 15 high-speed railway passenger stations in China. Results show that the energy consumption of the high-speed railway station is between 117–470 kWh/(m2·a). The energy consumption of the station is related to the area and the passenger flow. The energy use of the station using district heating is higher than that of the station without district heating in the same region. The higher glazing ratio induces good natural lighting in the station, but the uniformity of the lighting in the station is not good. The acceptable temperature range of passengers in winter is larger than that in summer. The average air change rate of the high-speed railway station is 3.2 h−1 in winter and 1.8 h−1 in summer, which is the main reason of high energy consumption of the HVAC (Heating Ventilation Air Conditioning) system in this kind of building.
