One of the most important methods of saving energy and providing indoor comfort conditions of buildings is the careful design of the façades. A “double skin glass façade” is optimally one of the best options that control the heat interaction between indoor and outdoor spaces. Two kinds of heating energy is usually transmitted through exterior envelope “conduction” and “radiation”. Double skin g...

Due to low cost, evaporative coolers are used in most of the central regions and in the warm and dry climate of Iran and are considered as one of the major consumers of electrical power. Most evaporative coolers use single-phase induction motors by connecting directly to the power grid. But their eefficiency is very low, and their replacement with high efficiency electric motors is considered b...

this paper reports a cfd modeling study on the possibility of using high temperature and low oxygen content exhaust gases as oxidant for combustion in an industrial furnace by a written computer program. under these conditions,the predicted results for the flow and heat transfer properties are compared with those under the several cases of conventional and highly preheated and diluted air combu...

Train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. On the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. First, we propose a fuzzy energy ...

Mass consumption of energy is a big problem. Energy-saving activities which are a solution to this problem have been attracting a lot of attention. Nevertheless, in order to engage in thorough energy-saving activities, consumers need support; on the other hand, even with support, the effects seem to be only temporary. In this paper, to obtain a long-term effect, we focus on developing a method ...

In recent years, machine learning techniques based on neural networks for mobile computing become increasingly popular. Classical multi-layer neural networks require matrix multiplications at each stage. Multiplication operation is not an energy efficient operation and consequently it drains the battery of the mobile device. In this paper, we propose a new energy efficient neural network with t...

Amid the information era, energy consumption of IDC Computer Room Air Conditioning (CRAC) system is becoming increasingly serious. Thus there is growing concern over energy saving and consumption reduction. Based on the analysis of the energy saving application of the air conditioning system in the present computer room, a new energy saving method of the IDC CRAC system, which presents energy s...

This study seeks to provide insights on understanding the contemporary problems of energy efficiency in Ukrainian universities by developing a comprehensive energy efficiency management framework that encompasses its participating subjects, objects and key drivers along with suggesting its implementation mechanism and tools. Emphasis should be given that the current situation of inefficient and...
