The paper reviews the Chinese policies on promoting building-integrated solar water heaters (SWHs) in urbanized areas and the corresponding experiences in implementing city-level demonstration programs using the Changjiang River (CJR) region as a study area. The progress of implementation, barriers, and effective promotion models are discussed. Furthermore, the installation potential of the SWHs in the study area are analyzed and compared with the achievements made to date. Finally, detailed policy recommendations are presented. © 2014 Elsevier Ltd. All rights reserved. Source

Influent and effluent quality of municipal wastewater treatment plants plays significant roles in selecting the appropriate treatment technologies and influencing the ecology of receiving water bodies. The quality of reclaimed water sources for water reuse can also be determined based on the influent wastewater and treated effluent information. Comprehensive analyses based on statistical data collected from 3340 Chinese municipal wastewater treatment plants were performed so as to better understand the effects of influent and effluent wastewater quality on the treatment performance, environmental concerns and resources utilization. Provincial characteristics of wastewater quality both in quantity and quality were identified, providing valuable information for the proposal of targeted management strategies in pollution control, water reuse and resources recovery. The influents of municipal wastewater treatment plants in north China had high wastewater pollutant loadings, but the effluent was of high quality due to the wide implementation of water reuse strategies in northern water scarcity regions. The potentials for organic and nutrient recovery from the influents were brought forward based on the mass balance. The importance of wastewater as a resource, and the adoption of advanced treatment and resources utilization in the long-term should be highlighted for sustainable water management. © 2016 Elsevier Ltd.

Energy Policy | Year: 2016

The energy efficiency of existing commercial buildings is more challenging to regulate and improve than the energy efficiency of new constructions. In 2011 and 2012, the Chinese Government selected four cities- Shanghai, Tianjin, Shenzhen, and Chongqing- to implement pilot commercial building energy efficiency retrofit program. Based on site surveys and expert interviews in these pilot cities, this research conducted a comparative analysis on incentive policies of local city level. The analysis results show that policy designs of existing commercial buildings should be further improved. The aspects that influence the implementation effect in the future, such as subsidy level, installments, and business model promotion, should be specified in the policy clauses. Referring to the technical solution and cost-benefit in Chongqing, we found that lighting system is the most common retrofit objects while envelope system is the least common one. And the subsidy incentive is greatest for educational buildings, followed by office buildings. In the end, we further discussed the problems and obstacles in commercial building retrofit market, and provided a series of recommendations. © 2015 Elsevier Ltd. Source

The character of poem is to discover the world from the viewpoint of aesthetics.When the poem is used as a design language, its character will be introduce into the design and the design process is translated into a process of seeking after poetic-images, constructing poetic-realm and designing follow the poetic-realm. Meanwhile, it will redound to reveal Chinese culture in the design because the poem is the typical feature and important expression way of Chinese culture.In designing the Huangxing commercial pedestrian Street in Changsha, the designer epurate instills poetry-images from local geography and culture, then integrates them into a poetry-realm,and design following it. In conclusion, the poem not only be a designing way ,but more important, a way to represent the glamour of Chinese culture and a kind of interpretation to the common idea of the Orient and the Occident for Poetic Dwelling. © 2011 IEEE.
