The building sector accumulates approximately a third of the final energy consumption. Consequently, the improvement of the energy efficiency in buildings has become an essential instrument in the energy policies to ensure the energy supply in the mid to long term moreover is the most cost-effective strategy available for reducing carbon dioxide emissions This paper is studying the main objecti...

this present research work was carried out to evaluate the energy consumption in a typical iranian building based on the forecast of climatic variables. thus, the lars-wg model was validated for some northwest stations of iran, including tabriz, ardebil, oromieh, kermanshah, hamedan, sannandaj, qazvin, and zanjan. the average monthly outdoor temperature was forecasted from 2011 to 2100. the rel...

in this paper, a study and design of energy conservation actions and the obtention of energy efficiency titles, according to the italian ministerial decree 20th july 2004, applied to lighting and electrical systemsin a school district managed by perugia province (italy), is presented.specifically, the analysis regarded the replacement of neon lamps with high efficiency ones, and the power facto...

With energy resource scarcity and energy crisis in the world, energy efficiency has become a subject of great importance. In warm and humid climates as well as cold and mountainous ones, annual energy consumption is too high to achieve desirable living conditions in built environments, and hence energy efficiency measures and practices in such buildings is of utmost priority. Given the direct r...

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...

This paper analyzes utilization of renewable energy systems and efficient building envelopes in the semi-arid climate. The proposed model evaluates renewable energy systems solutions as well as economic- and energy-efficient construction materials for the net zero-energy buildings (NZEB) in semi-arid climates. The objective of this paper is to optimize total energy cost and environmental impact...
