The objective of this study is to determine the appropriate bio-climatic design for the facades of beach hotels that are most exposed to solar radiation, in order to rationalize the energy they consume in climate control (i.e., air conditioning). The methodological approach used consists of identifying adverse environmental impacts in two selected case studies, employing a life cycle assessment of the operation of climate control systems. The results suggest the parameters that should be considered in achieving optimal façade design, to achieve energy savings. The study compares alternatives in the search for design improvements that can optimize energy management during the operational life cycles of hotels located in the southern continental coast area of the country
