The heat energy requirement in greenhouses throughout the production period is important in determining the production economy and feasibility studies to be conducted. Heat energy requirement in greenhouses is determined according to DIN 4701 standards by using mean heat temperatures. However, the calculations based on mean temperature causes misleading results in transition periods and in places where mean temperature is high. In order to have the most accurate heat energy requirement of a greenhouse, the hourly climate data should be used. In this study, the statistical correlations between the data of heating-degree-day (HDD) and heat energy requirements calculated by ISIGER-SERA expert system were determined for the provinces having potential of heating sources and where greenhouse are widely used in Turkey. The real heat energy requirement of the greenhouse is determined with the aid of coefficients calculated with the heat energy requirements obtained from statistical methods, type of the greenhouse (AH/AG) and heating system used in the greenhouse. The obtained results become easier to determine the heat energy requirements of the greenhouses to be installed in different regions having different HDD values and different equipment.
