E nergy consumption has increased significantly in Iran during the recent decades. In this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. The input-output tables of Iran for the years 1988 and 2001 have been employed as the database of the model. The innovation of this research allows the researchers to stud...

background : energy drink consumption has a direct relationship with high risk behaviors such as smoking and alcohol consumption. the aim of the present study was to investigate the pattern of energy drink consumption and its associated factors in college students. methods: a descriptive cross-sectional study was conducted on students of isfahan university of medical sciences, iran, in the acad...

Energy consumption has been essential to societies; because societies depend on the rising provisions of energy to meet their requirements for goods and services and endorse sustainable development. The major source of energy nowadays is oil; oil consumption is dependent on oil availability, production and price. Several Arab countries are considered as major suppliers of oil in the world; cons...

Building information modeling can help in predicting the energy efficiency in future based on dynamic patterns obtained by visualization of data. The aim of this study was to investigate the effective parameters of energy consumption using BIM technology which can evaluate the buildings energy performance. First, three forms of general states in the building were modeled to evaluate the propose...

In this research, energy data of the country from 1374 to 1397 are presented and econometric analysis and decomposition analysis methods (Laspeyres and Logarithmic mean Divisia index) are used to identify and determine the effect of activity, structure and energy intensity on energy consumption. The results of econometric method analysis show that the fitted function of energy consumption based...

unlike other studies in which the autours have focused on testing the existence of an environmental kuznets curve, in this study, causality relationship between the energy consumption (oil equivalent), carbon emissions, gross domestic production, total labor force and fixed capital formation is investigated during 1960 to 2007 in iran. following an examination of stationary tests for all the va...

Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...

According to research, between 15 to 20 percent of the total energy consumption of every country is used for residential spaces. This amount is explanatory of the high cost and will follow the destruction of natural resources and environmental demolition. The aim of this research is to recognize earth thermal ability and its usage in public buildings and especially in private buildings in order...
