Abstract

Today, organizing parts of cities that have worn out over time, as well as reducing energy consumption in cities, is an important issue for urban planners. This can have a significant impact on reducing the consumption costs and the environmental impact of fossil fuel consumption . The results of this study suggest that regeneration of worn-out tissue in cold climates with increased tissue density can be effective in reducing energy consumption. Because gas consumption for heating in this climate is more than energy consumption and correlation analysis results show that gas consumption has inverse relationship with number of floors and building age. On the other hand, it was observed that by changing the physical structure and consequently changing the social composition of households living in renovated buildings, the mean age and average income level increased and studies have shown that these conditions have a significant effect on increasing energy consumption, but from the factors that reduce and increase energy consumption in this study it was found that energy consumption in the apartment sector is about 88.19%, average consumption in worn out and About 87.14% show moderate consumption of non-worn and non-apartment parts

Highlights

In this study, it was found that the renovation of worn-out tissue in cold climates along with increasing tissue density can be effective in reducing energy consumption, because studies have shown that gas consumption for heating accounts for a larger share of energy consumption in this climate. And secondly, gas consumption shows an inverse relationship with the number of floors, so energy consumption in apartments replaced with dilapidated buildings compared to existing dilapidated buildings and non-dilapidated buildings with low floors is significantly reduced. But on the other hand, with the renovation and physical change of texture, we see a different social composition in the texture, so that the population living in renovated buildings have a lower average age and higher average income. Studies have shown that the average younger age consumed more electricity and Higher income includes higher electricity and gas consumption, so this study saw a multifaceted analysis of variables, and finally, considering all the studied aspects, it seems that despite the reducing effect of social and economic conditions of future residents of the renovated tissue in Energy saving, increasing density in worn tissue in cold climate due to reducing the level of contact with uncontrolled outdoor air and construction by observing the new principles of energy saving leads to a reduction in gas consumption, which ultimately consumes Will reduce energy in worn tissue in the home sector.
