  • analysis of typical Public Building energy consumption in northern china
    Energy and Buildings, 2017
    Co-Authors: Zeyu Zhang, Na Deng
    Abstract:

    Abstract In order to investigate the characteristics of Public Building energy consumption, energy consumption of 119 Public Buildings in North China have been counted and discussed. Main factors influencing the energy consumption of Public Building are analyzed by using eQUEST software. Based on the statistics, energy consumption variants and carbon emissions index of Public Buildings are determined under four situations. The results indicate that the average comprehensive energy consumption per unit area is 147.20 kWh/(m 2  a) and the average power consumption is 47.96 kWh/(m 2  a). Energy consumption level and characteristics of three typical Public Buildings are investigated. The comprehensive energy consumption per unit area of office, hospital and school Buildings varies from 26.76 to 475.27 kWh/(m 2  a); from 91.94 to 329.94 kWh/(m 2  a) and from 50.85 to 204.30 kWh/(m 2  a), respectively, and the average values are 188.36, 194.64 and 103.27 kWh/(m 2  a), respectively. It is found that the energy consumption of hospital Building is much higher than that of office and school Buildings. The power consumption per unit construction area in north of China is considerably lower than that of the United States and the United Kingdom, but closer to Japan. Among the discussed factors, air conditioning system, lighting density and Building envelope are the most significant impacts influencing the Building energy consumption. Different functional Public Buildings have different energy consumption variants and carbon emissions indexes. Based on the statistics, the average energy consumption variants of government office Building, non-government office Building, hospital Building and school Building are 169.98, 197.71, 206.92 and 118.54 kWh/(m 2  a), respectively. The average power consumption variants are 66.38, 75.88, 87.44 and 28.13 kWh/(m 2  a), respectively. The average carbon emissions indexes are 85.62, 93.22, 102.46 and 55.04 kg/(m 2  a), respectively.

  • Effect of urban micro-climatic regulation ability on Public Building energy usage carbon emission
    Energy and Buildings, 2017
    Co-Authors: Hong Ye, Xinyue Hu, Xinhu Li, Guoqin Zhang
    Abstract:

    Abstract Greenhouse gas emissions from Buildings energy consumption increase disproportionate since the 21st century which would accelerate exhausting the fossil fuel supply and threatening the local climate. Using factor analysis, we study the contribution of four groups of influencing factors to office Building energy consumption by integrating social economic, Building, macro-climatic and micro-climate regulation factors. It showed that micro-climate controlling ability had the least contribution (with 9.64%) to the office Building energy usages. Nevertheless, micro-climate regulation ability should not be ignored for its improvement process is relatively easier and the investment is lower when comparing with renovations on Buildings, macro-climate or social-economic conditions. Using a geographical detector model, the effects of urban micro-climate regulation ability on office Building energy consumption is further analyzed. The results showed that when integrated with green space and water body, the effect for carbon emission reduction was more obvious than using one of them alone. The green space had area threshold for office Building energy usages carbon reduction but water body has not. If land area permitted, water body construction is more suitable than green space for reducing office Building energy usage carbon emission. This study will provide urban low carbon Building construction from the view of planning and layout of ecological land such as green-space and water space.

  • Edge Computing, IoT and Social Computing in Smart Energy Scenarios.
    Sensors, 2019
    Co-Authors: Inés Sittón-candanedo, Lilia Muñoz, Óscar García, Ricardo S. Alonso, Sara Rodríguez-gonzález
    Abstract:

    The Internet of Things (IoT) has become one of the most widely research paradigms, having received much attention from the research community in the last few years. IoT is the paradigm that creates an internet-connected world, where all the everyday objects capture data from our environment and adapt it to our needs. However, the implementation of IoT is a challenging task and all the implementation scenarios require the use of different technologies and the emergence of new ones, such as Edge Computing (EC). EC allows for more secure and efficient data processing in real time, achieving better performance and results. Energy efficiency is one of the most interesting IoT scenarios. In this scenario sensors, actuators and smart devices interact to generate a large volume of data associated with energy consumption. This work proposes the use of an Edge-IoT platform and a Social Computing framework to build a system aimed to smart energy efficiency in a Public Building scenario. The system has been evaluated in a Public Building and the results make evident the notable benefits that come from applying Edge Computing to both energy efficiency scenarios and the framework itself. Those benefits included reduced data transfer from the IoT-Edge to the Cloud and reduced Cloud, computing and network resource costs.

    Co-Authors: Wang Xin
    Abstract:

    As an effective measure,pushing EPC modes applied in the market of the large-scale Public Building in China can resolve the low energy efficiency and difficult reconstruction.The status in quo of large-scale Public Building is summarized with the analysis of EPC modes.As to the selection of the modes,the influence factors are discussed from the owner of large-scale Public Building,ESCO and outside conditions and so on.Besides these,a multilevel evaluation model for large-scale Public Building energy-saving reconstruction,which is practicably and manipulatory,is set up based on fuzzy synthesis analysis.Guidance and suggestions for the large-scale Public Building owner can be gained in the future.
