In China,a new "Design standard for energy efficiency of residential buildings (for cold region)" was introduced in 2006. In this new standard,more high level insulation of the building envelope is required,yearly energy requirement for heating must be less than 55 kWh/(m2·a)(regarded as a low-energy house). The new attempt was carried out in the process of architecture design with an evaluation on energy consumption of the building. The design plan was brought forward and compared. PHPP software from German was applied to calculate energy consumption of the passive residential building. The optimum design planning was discussed and model of passive house suited to China's national conditions were attempted. The compactness,solar air collector and the window-wall ratio have essential influence on the energy consumption of buildings. The annual heat demands for the buildings with the window-wall ratio 0.35 and 0.50 are 48 kWh/(m2·a) and 46 kWh/(m2·a),respectively. The yearly auxiliary heat of building with the wall-mounted solar air collectors and the window-wall ratio 0.35 is just 4.8 kWh/(m2·a). 展开更多

There are few simple tools for architects to optimize the daylighting design. Therefore,it is useful to develop a design guideline related to the evaluation of lighting energy saving potential and sunlight design strategies. This paper analyzes the impacts of different artificial lighting control methods and design parameters on daylighting. A direct correlation between lighting energy consumption and parameters such as orientations,window to wall ratio (WWR) and perimeter depth is established. A simplified prediction model is proposed to estimate lighting energy consumption with the given perimeter depth,WWR,and window transparency. Validation of the model is carried out compared with detailed lighting simulation software for an office building. After the variation analysis for these parameters,design advises for the daylighting design at scheme design phase are summarized. 展开更多

Buildings are becoming smarter as a result of a variety of advanced technologies that enable energy management, optimal space utilization, and smart surveillance for safety, among other things. Energy-efficient smart building ideas and execution are of great interest and top priority due to the building’s occupants’ misused and high-power consumption. This paper addresses the design and execution of an energy management system that includes a solar power system for generating power for the building’s needs and a PIR-based automation system for efficient power use. This project was carried out at the Military Technological College (MTC) in Muscat, in the system engineering department’s offices. This project seeks to generate power for the building’s energy needs using solar photovoltaic panels and reduce energy consumption within the office using a PIR-based automation system. The results demonstrate that after the breakeven point (the time it takes to recoup the initial investment), it can provide power to the building for another 17 years. The calculations and practical results presented in this study approve that the system is extremely helpful. 展开更多

The construction industry is embracing sustainable building practices that boost the“triple bottom line”,namely the building’s ecological,social,and financial performance.Since more than 55 million US students spend a significant part of their day in K-12 schools,it is vital that these facilities should provide healthy,comfortable,and productive learning environments.Here we present an in-depth literature review of how educational facilities affect student school performance,comfort,and health,and we examine the role of sustainable design and construction strategies in influencing the physical learning environment in schools.Significant barriers to implementing sustainable strategies are examined,particularly the first cost premium of a sustainable building.A systematic decision strategy is described that incorporates sustainable design strategies,lowering energy consumption and improving indoor environments.A case study describes the process of incorporating sustainable strategies in a K-12 education facility in North Carolina to lower annual energy consumption and greenhouse gas emissions.Ways to reduce the first cost premium and minimize operating costs over the facility’s life while providing healthy and comfortable learning environments for students and teachers are discussed.The case study school also functions as an experimental learning tool for teaching sustainability to K-12 students,having the potential to improve their attitudes and behavior with respect to sustainability. 展开更多

The heating load simulation models of the residential buildings in Lhasa are established for enhancing the space organization’s adaptability to climate and radiation and improving its energy saving performance.The space organization items a e analyzed for both the existing buildings without insulation and new buildings with good insulation.The items include orientation design,south a d north balcony design,the north and south partition wall’s position design,storey height design and window-wall ratio design.Simulation results show that orientation is the key design element for energy saving design,and adverse orientation can obviouslyincrease heating energy consumption;south and north balconies can reduce winter heating energy consumption;partition walls move to the north,which means that the south room’s big depth design leads to less heating energy consumption,but the effect is not inconspicuous;smaier storey height results in less heating load.For the existing buildings,the window-wall ratio of south side has a balance point for energy saving design in the calculation condition.For the new buildings with good insulation,enlarging the south window-wal ratio can continuously reduce heating energy consumption,but the energy saving rate between models gets smaier.The heating energy consumption comparison study between the common model and optimal space design model demonstrates that the energy saving design can significantly reduce heating energy consumption 展开更多

Attempts to minimize energy consumption of a tunnel boring machine disc cutter during the process of fragmentation have largely focused on optimizing disc- cutter spacing, as determined by the minimum specific energy required for fragmentation; however, indentation tests showed that rock deforms plastically beneath the cutters. Equations for thrust were developed for both the traditional, popularly employed disc cutter and anew design based on three-dimensional theory. The respective energy consumption for penetration, rolling, and side-slip fragmentations were obtained. A change in disc-cutter fragmentation angles resulted in a change in the nature of the interaction between the cutter and rock, which lowered the specific energy of fragmentation. During actual field excavations to the same penetration length, the combined energy consumption for fragmentation using the newly designed cutters was 15% lower than that when using the traditional design. This paper presents a theory for energy saving in tunnel boring machines. Investigation results showed that the disc cutters designed using this theory were more durable than traditional designs, and effectively lowered the energy consumption. 展开更多

Climate change within the urban contexts is a crisis that cities are confronting globally.This issue poses numerous negative consequences such as thermal discomfort and increased energy usage within the building sector.This is especially the case in Western Sydney,Australia,where the average maximum temperature has risen by 7—8℃ within the past 30 years.This increase in temperature is highly concerning,since this region is witnessing rapid urban and infrastructural development and is proposed as the third-largest economy of Australia.Temperature changes in this region will also result in considerably increasing the electricity used for cooling purposes.This paper presents a parametric approach driven multi-objective optimization methodology to discover optimum design solution based on the urban microclimate and cooling energy demand of multi-functional buildings within this urban context.Mitigation measures including a range of design factors at both building(typology and window to wall ratio)and urban scales(aspect ratio and urban grid rotation)are further suggested for developing context sensitive optimum urban layouts.The resultant solutions indicate an improvement in urban thermal comfort,cooling and heating energy use by up to 25.85%,72.76%,and 93.67%,respectively. 展开更多

This paper presents a wireless sensor network (WSN) access control algorithm designed to minimize WSN node energy consumption. Based on slotted ALOHA protocol, this algorithm incorporates the power control of physical layer, the transmitting probability of medium access control (MAC) layer, and the automatic repeat request (ARQ) of link layer. In this algorithm, a cross-layer optimization is preformed to minimizing the energy consuming per bit. Through theory deducing, the transmitting probability and transmitting power level is determined, and the relationship between energy consuming per bit and throughput per node is provided. Analytical results show that the cross-layer algorithm results in a significant energy savings relative to layered design subject to the same throughput per node, and the energy saving is extraordinary in the low throughput region. 展开更多

Ecological design is defined as any form expression that minimizes environmentally destructive impacts by integrating itself with living processes. Ecological design is an integrative ecologically responsible design discipline. Layout of climate is one of the basics for the ecological design of Semnan. In this regards, the ecological design and the architecture of the city of Semnan are the means through which the city reinvents its identity and its structure and renews its face. Creating of healthy and restful occupant environments for human becomes one of the main infrastructure challenges upon modern ecological design and architecture which provides human health. Undoubtedly, there are also reasons for being optimistic upon the level of physical and mental wellbeing of individuals, reducing the incidence of diseases, and/or might reduce their total fuel consumption with adverse health effects, and environmental pollution. In the climate-related topics, the architecture of the building is considered with the climatic conditions of each region, which will result in more human comfort and energy saving in order to control the environmental conditions. The purpose of this research is to identify and review the architectural style and ecological design of the city in accordance with the climate and the climate guidelines that can be used in the areas of stability, comfort, beauty, health, energy efficiency, and the use of important climatic parameters (temperature, relative humidity, ...) extracted from the data bank of the Semnan Synoptic Station (1965-2005) and the Terjung Environmental Indexes. The thermal comfort conditions of the private and public bodies of Mahani and Givoni were reviewed and analyzed for the establishment of the buildings and seasons of the year. The results show that the weather is very cool at night in the months of March and October which are acceptable on the day in comfort area, and June, July and August are acceptable at the level of comfort in the city in the months of November to March in the day and October to March and in the months of April and May. Also, in the area of energy consumption, buildings should be placed in the east-west axis;long openings in the north and south of the building should be reduced to the sun. 展开更多

Green manufacturing is a growing trend,and an effective layout design method for production lines can reduce resource wastage in processing.This study focuses on existing problems such as low equipment utilization,long standby time,and low logistics efficiency in a mixed-flow parallel production line.To reduce the energy consumption,a novel method considering an independent buffer configuration and idle energy consumption analysis is proposed for this production line’s layout design.A logistics intensity model and a machine tool availability model are established to investigate the influences of independent buffer area configuration on the logistics intensity and machine tool availability.To solve the coupling problem between machine tools in such production lines,a decoupling strategy for the relationship between machine tool processing rates is explored.An energy consumption model for the machine tools,based on an optimized configuration of independent buffers,is proposed.This model can effectively reduce the idle energy consumption of the machine tools while designing the workshop layout.Subsequently,considering the problems encountered in workshop production,a comprehensive optimization model for the mixed-flow production line is developed.To verify the effectiveness of the mathematical model,it is applied to an aviation cabin production line.The results indicate that it can effectively solve the layout problem of mixed-flow parallel production lines and reduce the idle energy consumption of machine tools during production.The proposed buffer configuration and layout design method can serve as a theoretical and practical reference for the layout design of mixed-flow parallel production lines. 展开更多

In this paper, we propose a cross-layer design combining adaptive modulation coding (AMC) and automatic repeat request (ARQ) to minimize the bit energy consumption under both packet loss rate and retransmission delay constraints. We analyze the best constellation size of M-ary square quadrature amplitude modulation (MQAM) in different distance, and give advice on retransmission limits under different packet loss rates. The impacts of path loss fading and additive white Gaussian noise (AWGN)are taken into consideration. The computation of energy consumption includes the circuit, transmission and retransmission energies at both transmitter and receiver sides. Numerical results are obtained to verify the validity of our design. We also show that the retransmission benefit varies with the packet loss rate constraint. 展开更多

Advancing technology has enabled the production of smaller, more energy efficient and cheaper electronic components. Therefore, previously existing many computer and electronics science-engineering ideas have become feasible. One of them is the technology of wireless sensor networks (WSNs), which has become the realization of the necessary technical requirements applicable today with low energy consumption. First, the sensing tasks and the potential sensor networks applications have explored, and reviews of factors influencing the design of sensor networks have provided. Then, the communication architectures for sensor networks have been outlined. PIC-based microcontrollers have used in the design of the sensor nodes. The design of the sensor node has supported with ultra-low power nanowatt technology for very low-cost design. Processing, memory and wireless communication units have integrated on to the sensor nodes and sensors to be used in the designed system which have allowed to be connected to any kind of sensor node. The designed sensor node’s operating system has written with the PIC C language, and PIC operating system has allowed different features such as measuring humidity, temperature, light sensitive and smoke sensor. Computer software has developed for data that can be recorded and monitored from a central location. Decision-making unit has created in the software algorithm and hardware modules for the implementation of decisions taken by the developed sensor nodes. Developed PIC-based sensor nodes have supported a unique voltage unit with renewable energy sources such as solar panel, rechargeable battery, and supercapacitor for energy production and saving. The results of this study are expected to be helpful for the development of WSN especially with renewable energy sources. 展开更多

In order to reduce the increasing energy consumption for the domestic demands of existing single-family housing and take advantage of frequent building enlargements,this paper presents a methodology and supporting software tool for determining the optimal design configuration of an attic with integrated solar collectors.The analysis procedure is based on parametric modeling,energy simulation and the use of evolutionary algorithms for finding optimal designs.It has been implemented as a Web-platform for public use that provides users with a proposal of an attic shape with maximum solar energy collection,maximum living space and minimum construc-tion envelope for each house according its size and orientation.The attic integrates PV,thermal and hybrid solar panels on one side of the roof.This paper describes the methodology and software design,asssment of the Web-platform usage and case-studies to verify its behavior.In a matter of minutes,the Web-platform enables users to select a specific attic design for each house that has integrated solar collectors that can produce energy to cover almost 100%of domestic energy consumption.The attics designed provide a nearly 30%increase in living space through the extension of one to four rooms,and the construction cost of the envelope is similar to that of a standard housing extension. 展开更多
