[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.

With rapid economy growth, building energy consumption in China has been gradually increased. The energy consumption and indoor environmental quality of 51 office buildings in Hainan Province, a hot and humid area, were studied through collection of verified data in site visits and field tests. The result revealed that, electricity accounted for 99.79% of the total energy consumption, natural gas 0.17%, and diesel 0.04%. The air conditioning dominated the energy use with a share of 43.18%, equipment in the particular areas 26.90%, equipment in the office rooms 11.95%, lighting system 8.67%, general service system 7.57%, and miscellaneous items 1.73%. Statistical method including six indicators obtained the energy consumption benchmark with upper limit of 98.31 kW·h/m2 and lower limit of 55.26 kW·h/m2. According to ASHRAE standard (comfortable standard) and GB/T 18883-2002 (acceptable standard), the indoor environmental quality of 51 sampled office buildings was classified into three ranks: good, normal and bad. With benchmark of building energy consumption combined with indoor environmental quality, it was found that only 3.92% of sampled buildings can be identified as the best performance buildings with low energy consumption and advanced indoor environmental quality, and the buildings classified into normal level accounted for the maximum ratio.
