Energy Consumption Patterns

Electric energy consumption shares a great portion of commercial building energy. Electric energy saving is essential to reduce total energy consumption in commercial buildings. To draw energy saving methods, it is necessary to monitor real energy consumption patterns and analyze the results. We monitor the lighting and non-lighting energy consumption of eleven zones in a real working office building every fifteen minutes during eleven months. We observe and analyze the monthly and daily energy consumption patterns of all zones and draw several feasible energy saving methods. Moreover, the lighting and occupancy are monitored simultaneously in detail to investigate the unnecessary energy consumption. It shows the possibility of a great amount of energy saving. Because we analyze the energy consumption patterns in all zones, the drawn energy saving methods are applicable to the current building with some added infrastructure and expandable to other similar office buildings. Our result is expected to contribute to reducing the energy consumption in buildings.

Abstract The paper considers a generic model for a turbofan engine coupled to electromechanical (EM) elements used for energy conversion and storage in electric form. The electromechanical systems apply torque to the engine shafts, allowing for controllable power injection or extraction to and from the engine. The standard proportional-integral (PI) control law used to command fuel flow for turbofan speed regulation is maintained for compatibility with industry practices, leaving the electromechanical torque to be specified. The paper adopts an optimal control approach for this purpose, where a weighted combination of electric energy consumption and fuel consumption is minimized subject to the dynamics of the electrified propulsion system. The solution for the optimal torques is given by linear state feedback plus bias, with gains calculated numerically from engine linearization data. Energy balance equations are derived and used to guide the optimization, evaluate the resulting power distributions, and check for errors. Simulation studies are presented for a chop-burst transient and for a realistic flight mission profile with environmental input variations. The paper shows the economic advantage of operating the engine with the electrified components. Specifically, fuel burn can be reduced in exchange for electric energy, which must be replenished, but at lower cost.

This paper presents a methodology of tests of traction asynchronous drives applied in electric vehicles. It is similar to Urban Driving Cycle ECE-15 (UDC). The objective of the research is to verify the developed methodology through tests performed on a laboratory simulator, which consists of energy-saving asynchronous motor controlled by a frequency inverter (converter). Vector Control on the drive is used for smooth speed regulation over a wide range at high values of efficiency and power factor. Contemporary measuring and control devices and special software products are used for capturing the dynamic characteristics when starting, stopping and changing the speed set point of the drive. Some of tests are presented and an experimental verification of the developed methodology is made. An optimal setting of the drive parameters can be made to minimize the electric energy consumption.

In order to evaluate the energy-saving effect of the bamboo plywood as building enclosure, by measuring thermal conductivity of compound bamboo building enclosure with different moisture content, performance function between bamboo characteristic and thermal conductivity were deduced with numerical analysis method. First, we measured thermal conductivity with different moisture content. For the accuracy of data, we put a thin plastic film between the heating layer of the tester and the bamboo plywood to reduce water evaporation. Then we got the functional relation of moisture content and thermal conductivity, by using numerical analysis software. Finally, according to the national related standard and the performance of the bamboo plywood within different moisture content, we analyzed the advantages and disadvantages of the bamboo plywood as building enclosure. The results showed that the heat preservation and thermal insulation properties of bamboo plywood as construction materials are both stronger than traditional building materials such as reinforced concrete with different moisture content. Meanwhile, so as to ensure the heat preservation and thermal insulation properties and to achieve a good energy saving effect, wed better keep the moisture content of bamboo plywood in a low state.

Variable speed drive (VSD) is used not only for controlling the speed but also for saving the electric energyconsumption. In this research VSD is applied to 3 phase squirrel cage induction motor used for water pumping inthe industry. VSD is needed to be applied to induction motors because these motors are the largest electricconsumed. Measurement and calculation are performed in the two conditions, before and after attaching VSD inthe motor. Electric quantities are obtained by measurement in the input and in the output of VSD. While energyconsumption and consumption cost are obtained by calculation. Finally, calculation of energy saving and costsaving are perfomed by comparing those two conditions. Aplication of VSD in the induction motor has advantagesfor saving electric energy consumption dan making it last longer. The energy saving and cost saving per year result1.003.984,8 kWh and IDR 732.908.904 respectlively. The longer life is caused by reduction of energy consumption.

An innovative electrically operated automated Quad-maran is developed in this study. The vessel consists of 4 hulls and each hull is capable of yawing independently around its axis. The vessel is expected to sail and carry out environmental measurements automatically in waters like oyster farms, with an outstanding efficiency and brilliant energy-saving characteristics. An elemental research was first carried out to investigate the vessel’s resistance and propulsion performance as well as its electric energy consumption during sailing. Water tank tests were implemented on the actual hulls. Later, sea trials using the whole vessel were carried out in Ishikawa Prefecture, Japan, where the vessel sailed under remote control from a PC far away. Pool trials were also carried out. In this paper, detailed information is given on the design and working features of the Quad-maran automated vessel. Results of the tests and trials are evaluated, and the interference between hulls observed during tests is discussed. The electric energy consumption and as well as the relating efficiency are calculated and discussed.
