Civil aviation is a high energy consuming traffic department. Based on the method of the Intergovernmental Panel on Climate Change (IPCC), the CO2 emission amount and emission intensity of Chinese air transportation and typical airlines from 2005 to 2014 were calculated in this paper. Through the comparative analysis, it can be found that, with the CO2 emissions of Chinese air transportation and typical...
One of the major tasks for achieving building automation is to implement an effective control strategy on the heating, ventilating and air conditioning (HVAC) systems. The HVAC system should be properly controlled to provide a relatively constant and comfortable temperature as well as fresh and filtered air with a comfortable humidity range to the buildings. In this work, a hierarchical control structure...
Heating, ventilating and air conditioning (HVAC) systems have played an important role in building energy and comfort management. It is designed to provide a relatively constant and comfortable temperature in buildings and provide fresh and filtered air with a comfortable humidity level. In this paper, an optimal control strategy is proposed to control the HVAC system for maintaining building's indoor...
Smart buildings are becoming a trend of next-generation's commercial buildings, which facilitate intelligent control of the building to fulfill occupants' needs. The primary issue of building control is that the energy consumption and the comfort value in a building environment are inevitably conflicting with each other. To study the relation between energy consumption and occupants' comfort, a multi-agent...
The big challenge of the control system for the intelligent and green building is to maintain the maximum customer comfort with minimum energy consumption. In the paper, a customer-centered multi-agent control system is proposed to meet the challenge. Four different kinds of agents are described, which are switch agent, central coordinator-agent, local controller-agents and load agent. Particle swarm...
In this paper, a multi-agent intelligent control system is applied to design a control system for smart and sustainable buildings. Smart and sustainable buildings require solving conflicts between energy consumption and indoor comfort level. Also, user preferences should be taken consideration in the control system design. Hierarchical control architecture is introduced and utilized to design such...
