As per the first plan to be implemented in Asia, all residential and administrative buildings will be ranked from A to G whereby A is very efficient and G is the least efficient in terms of energy consumption. No energy label will be given to buildings ranked G. 

The plan on devising energy consumption standards for buildings was approved by Iran’s energy and oil ministries last year (ended March 19).
Managing Director of Energy Optimization Organization Abbas Kazemi told the Persian daily Iran that energy labels for buildings will become mandatory from the next Iranian year.
Kazemi said that in the first phase, these energy labels will be made compulsory for administrative buildings. The official noted that buildings constitute 40 percent of total energy consumption in the country, adding that devising related standards will help reduce energy consumption in Iran significantly. “Both producers and consumers should help reduce energy consumption in the country,” he said. Kazemi also said the label is expected to become one of the most important documents for selling and buying buildings. Like electricity, gas consumption will be calculated on the basis of kilowatt (KW).
The official went on to say that buildings consuming less than 100 KW of energy per square meter annually will receive the A label, pointing out that those use more than 500 KW per square meter per year will be ranked G. Kazemi noted that if the related standards are observed, energy labels will help reduce energy consumption in the country by 50 percent. Based on estimates made in various parts of the country, the average annual energy consumption of buildings per square meter is more than 600 KW which is very high compared to those in foreign countries.
The figure for Scandinavian countries located in the coldest region of the world is 60 KW, which is expected to reduce to 30 KW in the near future. 

Im ersten Halbjahr 2012 gingen die deutschen Lieferungen nach Iran um 22% zurück und erreichten einen Wert von 1179 Mio. €, allerdings lag das Gewicht der Lieferungen 158% höher als im ersten Halbjahr 2011. Die iranischen Lieferungen nach Deutschland verzeichneten einen wertmäßigen Rückgang von 47% und lagen bei 212 Mio. €, bei einem gewichtsmäßigen Rückgang von 77%. Das Handelsvolumen der beiden Länder ging um 27% zurück.

High oil prices and complicated financial schemes have helped the Iranian regime survive damaging sanctions, analysts and officials have said, even as oil production has plummeted and inflation has soared. ....  ..... http://www.ft.com/intl/cms/s/0/60bcb7b6-e470-11e1-affe-00144feab49a.html#axzz23ggbZa6S
