In 2003, the residential sector of Uzbekistan has consumed about 15.073 Mtoc (million ton of oil equivalent) of energy or 27.3% of the total energy consumed in the country. This value is approximately twice as much as that of residential sector of Turkey and Romania. The climate of above countries is comparable to that of Uzbekistan. In this article we suggest to use the heating degree-day method for determining the natural gas consumption norms for residential heating. Taking the climatic differences into account, the norms of natural gas consumption in respect to each resident are submitted for each region of Uzbekistan. The realization of suggested proposals allows saving about 9.2 billion m(3) of natural gas annually. (c) 2006 Elsevier Ltd. All rights reserved.
