The use of renewable energies, especially in metropolises has led to a reduction in environmental pollution and greater access to clean, renewable and sustainable energy. This paper evaluates the effectiveness of a national plan adopted by the Tehran city council for reducing air pollutions. This plan is designed to increase the share of renewable energies in residential buildings. This study a...

An advantage of portable air cleaners is that they can be positioned in different parts of a building and used where air cleaning is needed. This makes them a popular choice for use in residential buildings. In typical indoor particle modeling efforts, perfect air mixing and uniform contaminant concentration distribution are assumed. However, nonuniform spatial concentrations of particles are m...

abstract: appealing to the principle of vertical residence and stemming the horizontal expansion of the city, the tehran milad tower is being built on 35000 sm3 site with the total area of 220000 sm3. with a height of over 170m, this 56-story concrete building is in the final stages of construction and would be the highest residential building of iran. since tehran is located in a high-risk ear...

The increasing demand for sufficient and clean energy forces industrial and service companies to align their strategies towards efficient consumption. This trend refers also to the residential building sector. There, large amounts of energy consumption are caused by house and facility heating. Many of the operated hot water heating systems lack hydraulic balanced working conditions for heat dis...

acoustic experimental data of irib (islamic republic of iran broadcasting) server room was taken to measure the acoustic noise characteristics of frequency and sound pressure level (spl). the purposes of this paper are measuring the noise pollution and its evaluation through the regulations. the measurements were taken in two stages. the first one was taken at 10 points by sound investigator 22...

in this research multiple-regression analysis with stepwise selection method was employed for investigating the effectof vertical building envelopes solar radiation (evr) on cooling energy consumption (e cooling) in residential sector.the high capacity of solar energy in semi-arid climate (shiraz) can provide a part of buildings required energy. dependson house orientations in two directions of...
