Abstract This study conducted a building energy simulation (BES) to compare the heating and cooling loads of a stand- alone greenhouse with a small hotel with an integrated rooftop greenhouse. The TRNSYS program was used to calculate the heating and cooling loads of the buildings. Numerical simulations were conducted for the stand-alone greenhouse model, a stand-alone small hotel model, and a small hotel with an integrated rooftop greenhouse model to compare the heating and cooling loads of each building. The results showed that the heating loads and total loads of the integrated model were reduced 20% and 15.7% than stand-alone model, respectively. Furthermore, if the temperature setting of the greenhouse was changed for different vegetables, the heating and cooling loads of the buildings varied. The setting temperature for high-temperature vegetables showed the largest energy reduction in the heating and cooling loads of the buildings. In conclusion, the integrated rooftop greenhouse had the advantage of energy reduction when it was installed on a conventional small hotel.
