Most currently used shutters are manually operated. The design of an intelligent shutter has been proposed. The intelligent shutter can be powered by a solar battery. Photosensitive resistors have been used to determine if it is in daytime or nighttime, if it is sunny or not, and if the light is turned on or turned off. Digital temperature sensors have been used to detect the indoor temperature and the outside temperature. They are also used to determine the current season. The intelligent shutter is automatically controlled according to the above information. It is turned off at night and is set in sleep mode to save energy. It is turned on partially on sunny day in summer. In rainy day, the shutter is turned off while the indoor light is on. The intelligent shutter can also be controlled using a wireless remote controller, which makes it very friendly. It is comfort and energy-saving using the intelligent shutter. Experiments have demonstrated the applicability of the design.

Some of the natural disaster occurred caused by people using natural resources unwisely. Before analyzing about that behavior, first will be analyzed is behavioral intention. The purpose of this study was to determine the effectiveness of cooperative learning group investigation type with the theme of “limited natural resources” to improve intention to save energy. The study used an experimental design Post-test-Only Design With Equivalent Groups, involving 66 people, divided into two groups, each 33 in the experimental group and 33 control group. Process experiments were conducted in a way, dividing the experimental group in 5 small groups, having given the matter of limited natural resources, then each group discussion, and sharing ideas with other groups in the jigsaw. The results showed that there are differences in energy-saving behavior intention significantly between the experimental group (KE) and the control group (KK) with t value of 3.192 with 0.002 significance (p <0.05). Differences KE and KK with a positive t value indicates that the energy-saving behavior intention at KE has a higher value than the families who were not given the manipulation. In general score KE and KK if joined at the high category, but if sorted, KE scores at the high category and score KK in middle category.

Energy consumption all over the world is constantly growing. To save energy, new technologies are being developed for the efficient use of energy resources. The goal of all new developments is to use less energy to provide the same level of energy supply for technological processes or buildings. The problem of energy saving is relevant for the ventilation system. Together with the removed air, a large amount of heat is lost, which is not advisable. In order to avoid these losses, heat recuperators began to be used, heating the cold supply air due to the warm air removed from the room. This development belongs to the field of energy saving. The goal is to increase efficiency by reheating the air after the heater with the help of a recuperator for a given temperature difference in the supply air before and after the recuperative heat exchanger. The development is a design of a ventilation unit with air removal and supply air ducts, combined into one housing with a separate, according to the “screw” principle, heat transfer wall, for use in the ventilation system in order to ensure an optimal microclimate in the room. Thus, as a result of using the presented device, the efficiency of the room ventilation unit is increased by reducing the energy consumption for heating the supply air with a heater.

PurposeEnergy-saving behavior of individuals is essential to minimize energy use and reduce the emission of toxic gases. This study's actual focus is to find out the determinants of the energy-saving behavior of individuals in the workplace.Design/methodology/approachAs a theoretical research model, the extended theory of planned behavior (TPB) has been used to analyze the determinants of energy-saving intentions. A survey method is used to collect 289 valid data, and structural equation modeling (SEM) is used to analyze the data.FindingsThe final result shows that the variables attitude at home, subjective norm (SN) and descriptive norms positively impact intention to save energy at the workplace. In contrast, the construct attitude and perceived behavior control is insignificant in this research. On the other hand, the personal moral norm (PMN) is a powerful predictor of individual energy-saving intentions at the workplace.Originality/valueThis research provides insights that will help the organizations understand the behavior of individuals at the workplace for energy-saving intentions to formulate such policies that will enhance individuals' practice for energy savings.

In 2007, the Green500 list was introduced, which compares supercomputers by performance-per-watt. Since supercomputers consist of thousands of nodes, energy-saving is a growing demand. Compute clusters are often managed by a so-called Resource Management Systems (RMS), which have load information about the whole system. For clusters with changing compute demands, this can be used to switch on/off nodes according to the current load situation and save energy this way. Here, the authors present energy-saving techniques that work on the management level and measurements that show that speed scaling is not a good means for energy saving. Further, they give an overview of some important standards and specifications related to energy saving, like ACPI and IPMI. Finally, the authors present their energy-saving daemon called CHERUB. Due to its modular design, it can operate with different Resource Management Systems. Their experimental results show that CHERUB’s scheduling algorithm works well, i.e. it will save energy, if possible, and avoids state flapping.

In the last years a new challenge turned out for both researchers and industries in telecommunications area is represented by green networks. Besides energy saving that is possible to achieve, another positive side effect of this is the reduction of the working temperature of internal components of telecommunications devices (switches, home gateway, routers, etc.). This idea is encouraging the development of routers of reduced dimensions as long as there is the knowledge that the temperature remains in a given range. For this reason the target of this paper is to propose a governor policy that provides the best trade-off between quality of service and energy saving in respect of a given target on the working temperature. More specifically, such a governor is in charge to manage the clock frequency of the Central Processor Unit (CPU) of the green router according to the traffic loading the router, varying the processing engine performance, the working temperature and the power consumption of the hardware at the same time. The proposed policy is then applied to a case study and evaluated by simulation to show how it can be used for the above purposes, and to allow green router designers to control the temperature statistics of a router and design the governor parameters to maintain the mean temperature below a given threshold.

The article considers problems and prospects of development of energy saving technologies in construction. The possible directions of improving the construction of residential facilities with the aim of increasing their efficiency are considered, taking into account different technologies. The main emphasis is on the use of solar panels as one of the most effective ways of saving resources. The maximum level of heliotropia for the Central black earth region is determined. To increase the efficiency of the solar battery it is proposed to develop a rotary device that allows you to change the angle of the battery in the vertical and horizontal planes. The dynamics of rotation in the horizontal plane should depend on the time of day, in the horizontal – season. The article presents the problem of determining the speed of rotation of the solar battery in the direction of the solar azimuth and relative to the horizon during the day, allowing you to use a slewing device with maximum efficiency. Increase efficiency when using the rotary mechanism will reduce the number of solar batteries with the same capacity of electricity consumption. Also the problem of determining the optimal number of solar panels.

<p><span style="font-family: 宋体;">Considering the indoor temperature monitoring and energy saving control technology, based on the traditional low energy adaptive clustering hierarchy (LEACH), a multi-hop clustering routing algorithm is proposed. By adding a threshold in LEACH, the algorithm makes the nodes with high residual energy and high nodes become cluster heads. The results show that the improved algorithm can effectively prolong the life cycle of wireless sensor networks. Based on above findings, it is concluded that the proposed algorithm can save the system energy and improve the network energy efficiency.</span></p>
