State-of-the-art technologies for pilot project buildings in the New Town of Hashtgerd in Iran

This project uses state-of-the-art technologies for pilot project buildings in the New Town of Hashtgerd in Iran. Seasonal energy consumption has been reduced due to the usage of renewable energy, structural measures, and high-tech materials. Also, the earthquake resistance of buildings is now higher.

 

Summary

New Towns are cities planned and constructed taking into consideration newest standards, which due to their proximity to high density population areas provide relief from development pressure. The present project adopts this principle of sustainable development for cities that are planned and constructed in Iran. The project deals with the question whether the development and construction of New Towns can serve as a central planning strategy for relieving the pressure from fast developing city agglomerations (cities and their suburban townships) in a country with a high percentage of young people. The object of the study is Hashtgerd, the largest of 30 planned New Towns in Iran. Hashtgerd is located in proximity to the megacities of Tehran and Karaj. One of the key points of the project is the use of latest construction technologies which have up till now not been used in Iran. These technologies will help improving the standards for earthquake resistance, as well as those for energy consumption while taking into consideration climatic comfort.

 

Results:

  • The facade consists of aluminium panels, double glazing, and a rear-ventilated double-layer facade. For the latter, EFEP (terpolymer made of ethylene, tetrafluoroethylene, and hexafluoropropylene) foils and ETFE (alternating copolymer made of ethylene and tetrafluoroethylene) blinds are used. These have a strongly reflecting surface.
  • The applied technologies reduce heating in summer and cooling in winter, thus lowering the energy consumption of the building (e.g. air conditioning).
  • The typical building layout for New Towns was replaced by a symmetrical floor plan without offsets in columns and reinforcing walls, in order to increase the earthquake resistance.
  • The solar modules and collectors on the roof not only produce electricity for the building, but also provide shade.
