Achievement Summary of Pilot City for Building Energy Efficiency in Shenzhen

Abstract China’s Ministry of Construction (MOC) issued new residential building energy codes for its ‘Hot-Summer Warm-Winter’ (HSWW) climate zone at the end of 2003. One of our four building codes implementation pilot cities in the HSWW climate zone, Shenzhen is among the cities leading the country in implementing these codes. This report by the Shenzhen Institute of Building Research (SIBR) describes the building inspection procedures, technical standards, and building energy efficiency calculation software developed by SIBR to help Shenzhen implement these codes. It also details SIBR’s efforts to train inspectors and technicians on building energy efficiency and codes implementation and to conduct a pilot project in a town near Shenzhen demonstrating the effectiveness of the SIBR.

An Energy Standard for Residential Buildings in South China

Abstract To curb the spiraling demand for building energy use, China’s Ministry of Construction has worked at developing and implementing building energy standards, starting with a standard for heated residential buildings in the Cold regions in 1986, followed by a standard for residential buildings in the Hot Summer Cold Winter Region in central China in 2001. In July 2001, a similar effort was started to develop a standard for residential buildings in the Hot Summer Warm Winter Region, comprising of the entirety or large portions of Guangdong, Guangxi, Hainan and Fujian. The target for the standard is to improve the thermal efficiency of buildings by 50% compared to current construction, which are typically uninsulated and have single-pane windows. Because of the importance of controlling window solar gain, the standard developed tables specifying the required window thermal transmittance and shading coefficient for differing window-to¬wall ratios. The intent of such trade-off table is to permit flexibility in the location and size of windows, as long as their thermal performances meet the requirements of the standard. For further flexibility, the standard provides three methods of compliance: (1) a simple set of prescriptive requirements, (2) a simplified performance calculation, and (3) a detailed computer-based performance calculation using a Custom Budget approach.

Development of China’s Energy Efficiency Design Standard for Residential Buildings in the “Hot-Summer/Cold-Winter” Zone

Abstract To respond to increasing energy use in the building sector, China has a national effort to develop Energy Codes for building construction. Several years ago, an Energy Code was promulgated for the northern portion of the country, where energy consumption for heating is the primary concern. In 2000-2001, an Energy Code was developed for residential buildings in the “Hot-Summer/Cold-Winter” Zone along the Yangtze River. The Compiling Team consisted of representatives from key cities within the region (Chongqing, Shanghai, Wuhan, Nanjing and Chengdu). International support was provided by the Energy Foundation, the Natural Resources Defense Council, and the Lawrence Berkeley Laboratory.  This work was complicated by the fact that the “Hot-Summer/Cold-Winter” Zone area has both significant heating and cooling loads. Consequently, the “Hot-Summer/Cold-Winter” Zone Energy Code needed to be more sophisticated than the previous Energy Code adopted in China. In addition to balancing the relative importance of heating and cooling loads, the project also involved a judgment of how comfort conditions in residential buildings might be expected to improve over time. The range of energy efficiency measures that were evaluated is presented (including multiple glazing, frame and shading options for windows, and insulation options for the walls and roof). The weather data used is summarized in a companion paper. Key aspects of the code format, compliance options and requirements are outlined.

A Joint US-China Demonstration Energy Efficient Office Building

Abstract In July 1998, USDOE and China’s Ministry of Science and Technology (MOST) signed a Statement of Work to develop a demonstration energy-efficient office building and demonstration center in Beijing that will eventually house the Administrative Center for China’s Agenda 21 (ACCA21). The statement calls for the Chinese side to be responsible for the basic construction of the 13,000 m2 9-story building, the US side for technical assistance and the incremental costs of the energy efficiency improvements, and the joint establishment of a Demonstration Center to provide outreach and exhibit energy-efficient building technologies. The US technical team made several trips to China to meet with ACCA21 and the design team, and used the DOE-2.1E simulation program to analyze the energy performance of a preliminary building design and study alternative designs and energy-efficient strategies. A feasibility study completed in September found the largest and most cost-effective savings potentials in reducing cooling and lighting energy use, and identified eight generic measures in lighting, windows, daylighting, and HVAC systems and controls. Following these and other recommendations from the US team, the design team produced a schematic crossshaped building design that, based on the DOE-2 analysis, lowered total energy use by 40% compared to standard practice. While the design and analysis were underway, a task force called ACCORD21 (American-Chinese Council Organized for Responsible Development in the 21st Century) was formed in April 1999 under the leadership of NRDC to solicit support and contributions from U.S. industry, A/E firms, and universities. Two design workshops were held, first in Pittsburgh and then in Beijing, that brought together the Chinese and US project participants and produced further refinements and energy-efficiency improvements to the building design. As of June 2000, the authors are completing the final energy analysis and selection of energy-efficiency measures. Construction is expected to begin in the early part of 2001.

Energy Use in Buildings: The U.S. Experience and Lessons for China

Abstract This paper covers three topics concerning energy use in buildings. Its main focus is that of energy use in buildings in the United States. A second section describes some of the recent results of work by one of the authors on energy performance of residential buildings in China. The third section contains suggestions for ways in which Chinese and U.S. researchers could establish fruitful collaborations on energy use in buildings.
