摘要：The objective of this study is to select roof material for silkworm house using the costs of roof material and total heat requirements (THRC). For this aim, three different silkworm house of the same size were planned, one of which had flat reinforced concrete (RCC) and the other two had gable roof, in which uninsulated galvanized sheet metal (UGSM) and sandwich panel (SP) were used. The selection of roof materials was made according to the roof materials costs and THRC. With started breeding on 1st May, the THRCs for RCC, UGSM and SP house in the 5 larvae period of silkworm were 5483, 7429, 3925 W h 1 and their THRC were 74.12, 94.33 and 57.19$, respectively. The THRC of the SP house was found to be 22.83% and 39.37% less than RCC and UGSM. The costs of RCC, UGSM and SP roofs were calculated as 1172.79, 873.92 and 1470.44$, respectively. The cost of UGSM roof was determined to be 25.48% and 40.57% lower than that of RCC and SP. Although the SP roof cost was the highest among the roofs’, SP’s THRC was the lowest among them and no dew occurred in all larvae periods on the inside surface of SP roof and also provided the more stable environmental conditions in the house during the larvae periods. That is why, SP roof could be suggested to build silkworm house the growers.
