[ScienceDirect, via Biblio-SHS] Auteur : Wilco Chan Paru dans : International Journal of Hospitality Management, Volume 31, Issue 4, December 2012, Pages 1130-1142 Abstract Achieving effective and objective energy benchmarking for hotels is integral in fostering the sustainable development of the lodging sector. In this work, we reveal the major and minor streams of hotel energy benchmarking and ascertain that the most popular approach in benchmarking is normalized energy use intensity (EUI) based on floor level. Previous efforts to establish EUI indicators using subsystem average, data envelopment analysis (DEA), and regression technique are also studied. We propose that hotel energy benchmarking based on floor area is useful from the top-down management perspective. However, on a practical perspective, energy benchmarking based on facilities should be the first priority for hotel management or owners. Compared with the general energy benchmarking in the building sector, we find that the hotel sector lags behind in the adoption of computer modeling for benchmarking. By conducting in-depth interviews with hotel engineers, system designers, and professors to identify the challenges faced by current hotel energy benchmarking, we gain deeper insights on the development of hotel energy benchmarking that reflect the current situation in China. A taxonomical approach focusing on four directions of hotel energy benchmarking is thus proposed. By coordinating with various types of stakeholders and implementing the proposed development plan, the local Construction Ministry, Tourism Bureau, and Energy Improvement Office can realize this conceptual hotel energy benchmarking in China.

Centre for Sustainable Energy Technologies, The University of Nottingham Ningbo China 27th to 28th October 2012 Ningbo, Zhejiang, China The building sector is one of the highest energy consuming sectors in China accounting for about 30% of total energy usage and also contributes to a significant proportion of pollutant emissions in China. Meanwhile, building construction activities are contributing significantly towards China's economic growth and infrastructure development under the current urbanisation programme. It is estimated that half of the world's buildings being constructed between now and 2020 are expected to be built in China and if nothing is done to control the upward energy trend, building-related energy consumption could double and have a devastating effect on the environment and the economy as a whole. The objective of this international symposium is therefore to provide a forum for academics, government officials, researchers and practitioners to present and discuss recent research and demonstration projects related to low carbon buildings in China. The event will feature well known international experts in this field as Keynote speakers.

[ScienceDirect, via Biblio-SHS] Auteur : Guiwen Liu, Zezhou Wu, Mingming Hu Paru dans : Energy Procedia, Volume 14, 2012, Pages 1925-1930 Abstract Around 30% of the national energy consumption in China can be attributed to buildings, of which one-fifth is consumed within public buildings. In recent time, public buildings have been reckoned as the dominant objects for conducting energy efficient management. In order to obtain valuable information for the assessment of energy consumption status, an investigation was conducted in Chongqing - the youngest, largest and most dynamic municipal in China. A number of public buildings, including 28 governmental office buildings, 15 emporiums and 5 hotels, were selected for the investigation from the aspect of energy cost. Based on the collected data of electricity, water and gas, the characteristics of the energy consumption in each type of the public buildings are discussed, and the energy management in each type of public buildings is compared. 2011 2nd International Conference on Advances in Energy Engineering (ICAEE)

[ScienceDirect, via Biblio-SHS] Auteur : Zhang Xianchun, Shan Zhuoran Paru dans : Energy Procedia Volume 16, Part A, 2012, Pages 353-358 2012 International Conference on Future Energy, Environment, and Materials Abstract The urbanization level of china will exceed fifty percent in 2011. At the present stage, the urban-rural dual structure is more and more prominent. Due to the urban-rural dual management,many problems were found in the joint of urban and rural in the process of urbanization. This article summarizes the related achievements of land-use and management of Chinese joint of urban and rural for the last two decades. It introduces case-study in three aspects of cognitive, methodology and space planning, and discourses the achievements of different land-use types in the points of construction land, non-construction land.At the same time, this article elaborates the researches in landmanagement and points out the current excellent processes and the main problems.Finally, this article proposes the anticipation and prospect of study in the future.

[ScienceDirect, via Biblio-SHS] Auteur : Shuxiao Wang, Jiming Hao Paru dans : Journal of Environmental Sciences, Volume 24, Issue 1, January 2012, Pages 2-13 Abstract This article analyzed the control progress and current status of air quality, identified the major air pollution issues and challenges in future, proposed the long-term air pollution control targets, and suggested the options for better air quality in China. With the continuing growth of economy in the next 10-15 years, China will face a more severe situation of energy consumption, electricity generation and vehicle population leading to increase in multiple pollutant emissions. Controlling regional air pollution especially fine particles and ozone, as well as lowering carbon emissions from fossil fuel consumption will be a big challenge for the country. To protect public health and the eco-system, the ambient air quality in all Chinese cities shall attain the national ambient air quality standards (NAAQS) and ambient air quality guideline values set by the World Health Organization (WHO). To achieve the air quality targets, the emissions of SO2, NOx, PM10, and volatile organic compounds (VOC) should decrease by 60%, 40%, 50%, and 40%, respectively, on the basis of that in 2005. A comprehensive control policy focusing on multiple pollutants and emission sources at both the local and regional levels was proposed to mitigate the regional air pollution issue in China. The options include development of clean energy resources, promotion of clean and efficient coal use, enhancement of vehicle pollution control, implementation of synchronous control of multiple pollutants including SO2, NOx, VOC, and PM emissions, joint prevention and control of regional air pollution, and application of climate friendly air pollution control measures.

Abstract: Threatened by the huge pressure caused by climate change, low-carbon cities have become an inevitable part of urban evolution. It is essential to evaluate urban low-carbon development levels to smoothly promote the construction of low-carbon cities. This paper proposes an evaluation index system for urban low-carbon development from the points of view of economic development and social progress, energy structure and usage efficiency, living consumption, and development surroundings. A weighted sum model was also established. Selecting 12 typical Chinese cities as cases studies, an integrated evaluation was conducted based on the index system and the assessment model. The development speed and limiting factors of different cities were also analyzed. The 12 cities were ultimately classified into three groups in terms of their low-carbon development patterns by integrating all of the analysis results. Furthermore, suitable regulation and management for different patterns were suggested. This study both aids in assessing the executive effect of low-carbon city construction and helps to determine existing problems and suggest effective solutions.
