Abstract—İstanbul is the second largest and important tourism destination after Antalya in Turkey. 12,414,677 tourists visited İstanbul, whose total bed amount was 143,782 in 2015. The decisions that are composing the orientation of accommodation buildings affect the profitability of the facilities, use of sustainability of the resources and sustainable tourism (orientation to view and energy saving). The purpose of this study is to scrutinize the decisions, which have been made for the orientation of the bed masses, and to analyze these decisions by way of twenty sample hotels and to tabulate this analysis. Methods and materials; Maps showing all hotels in İstanbul have been obtained. Number of hotels in each province of İstanbul has been obtained. The results indicate that the hotels are concentrated in the culture triangle [24] and the historical peninsula. Twenty sample hotels have been selected considering the location, type, orientation and relation with view criteria. Particular wind maps for the selected hotels have been used for identification of dominant wind, speed of wind for each season and direction thereof, which affects the bedroom masses. Orientation decisions have been reviewed under climatic, environmental and regulative titles and the result been tabulated. In this study, twenty hotels’ bed mass orientation decisions have been analyzed in respect of decreasing the heating-cooling loads by way of orientation. Orientation of building façade, windward in summer and sunward in winter, is very important for the profitability of a facility and sustainability of the resources. Bed mass orientation decisions have been classified under three main titles, which are climatic (heating-cooling loads, sun light, wind) environmental (street access, activity zone, view restriction, pricing policies, location of shading elements) and regulative titles and tabulated accordingly. Bed mass orientations of twenty sample hotels, in the table, have been examined in detail as per the aforementioned design-related decisions.
