Cooling, heating and ventilating systems devote a great amount of this consumption so studying natural ventilation systems have become more important in order to improve their performance. In this paper, air flow has modeled by a computational fluid dynamic model with finite volume method in solar chimney as a new kind of natural ventilation system and in a combined system with Baadgir. For this reason, different turbulent models have been compared by a valid statistical test in order to find a suitable turbulent model in these systems and at the end a ke-RNG model has been selected. Also the effect of increasing height, span width and thermal gradient of the walls on improvement of solar chimney’s performance have been studied by computing parameters like mass flow rate and mean velocity.

In relation to demolition management, only standards and codes and general principles of demolition of specific buildings were evaluated. The purpose of this study is providing relation between lean management on demolition processes of municipality buildings evaluated. Design/methodology/approach This study investigates the lean demolition of demolished and renovated buildings in a metropolitan area that can be extended to all cities. In the first stage, the effective factors in the demolition of the building based on lean management were identified through a valid questionnaire based on the valid Delphi approach. Social, economic and environmental considerations were considered in designing the appropriate questionnaire. Findings The modified approach between the fuzzy method and partial least squar...
