“…The government has attempted to decrease the energy consumption and also conserve and manage its energy resources through some measures (Kang and Wei 2005;Jiang and Hu 2006;Li 2008;Li and Colombier 2009). However, inadequate attempt has been made to assess the environmental impacts of the buildings in China.…”

“…Buildings in China have become an increasingly important energy-demand sector accounting for nearly one fourth of total primary energy consumption and are very likely to increase to 35% by 2030 whereby 25% of GHG emission are being produced in the building sector (Li 2008). It has been identified as one of the main factors of energy use and greenhouse gas emissions.…”

Purpose Building is one of the main factors of energy use and greenhouse gas emissions. Reducing energy consumption and carbon dioxide (CO 2 ) emission from building is urgent for environmental protection and sustainable development. The objective of this study is to develop a life cycle assessment (LCA) model for an office building in China to assess its energy consumption and CO 2 emission, determine the whole life cycle phases, and the significant environmental aspects that contribute most to the impact. Methods A process-based LCA has been used to identify and quantify the energy consumption and CO 2 emission of the office building. The LCA is conducted in accordance with the Environmental Protection Agency, The Society of Environmental Toxicology and Chemistry, and the International Organization for Standardization standards for life cycle assessments. The entire life cycle including building materials production, construction, operation, and demolition of the building is studied. A service life of 50 years is assumed and the major construction materials such as concrete, cement, brick, steel, timber, glass, and plastic are selected for the building. Results and discussionThe results show that building operation uses the largest share of energy and contributes most to CO 2 emission. The cooling and heating system in building operation strongly influence the energy consumption and CO 2 emission of the building. In addition, the large quantity use of concrete and steel in materials production, and the treatment of end-of-life building materials are also the important aspects impacting the environmental performance of the building. Based on the results of the study, some environmental improvements aiming at reducing energy consumption and CO 2 emission throughout the life cycle of the building are provided.Conclusions This study provides an LCA of the energy consumption and CO 2 emission of a typical office building in China. It determines the whole life cycle phases that contribute most to the impact and defines the significant environmental aspects of the building. This study also shows the importance of using a life cycle perspective when evaluating energy consumption and CO 2 emission of building and also lays the groundwork for LCA studying of other office buildings in China.

“…Within the building sector, multiple studies have found that efficiency improvements are the most cost-effective and timely method for mitigating demand growth and extending service provision. 44 Improvements of building operational energy efficiency often come at the cost of increased embodied energy. A 2010 study of a "low energy" residential building in Italy, for example, found that while the winter heat requirement was reduced by a ratio of 10:1 compared to a conventional building, the overall lifecycle impacts were only reduced by 2:1.…”

“…Meanwhile, foreseeable high energy demands and import dependency of fossil fuels is another important driving force for the nation to explore a low-carbon pathway (Chai and Zhang, 2010;Li, 2008;Liu and Gallagher, 2010;Zhang, 2010). Specifically, the energy transition from low efficiency coal to oil, gas and renewable sources will be accompanied by a series of socioeconomic transitions: from agriculture to urbanization and industrialization, from heavy industry to light and high tech industry, from low motorization to rapid growth of the motor vehicle population.…”

2050 pathway to an active renewable energy scenario for Jiangsu province

et al. 2013

View full text Add to dashboard Cite

In 2009 Jiangsu province of China supplied 99.6% of its total energy demand with fossil fuels, of which 82% was imported from other provinces and countries. As energy demand soars, the problem of energy shortage worsens, and the degrees of pollution aggravate, it is essential for Jiangsu to put more emphasis on improving its energy efficiency and utilizing its renewable resources in future. This paper presents the integrated energy pathway for the transitional economy and society of Jiangsu by 2050. EnergyPLAN is chosen as the energy system analysis tool, since it accounts for all sectors of the energy system that needs to be considered when integrating large-scale renewable energy. A Current Policy Scenario (CPS) based on current energy policies and an Ambitious Policy Scenario (APS) based on large-scale integration of renewable energy and ambitious measures of energy efficiency improvement are proposed respectively. The energy pathway under these two scenarios are modeled and compared in terms of technology combination, renewable energy percentage, socioeconomic cost, and can provide valuable implications for Jiangsu's future energy policies.
