With high incident solar radiation on the East-West building facades located especially inrntropical climate regions like Ethiopia, the indoor spaces adjacent to glazed facades will becomernoverheated. Among the various techniques of solar heat gain controls in the tropics, applicationsrnof fixed exterior shading devices play a major role in blocking incident solar radiation first hand.rnThrough a descriptive research design, this study aims to investigate the effectiveness of suchrndevices as a passive means of solar control as well as identify a context based shading approachrnthat responds well during identified overheated periods in Addis Ababa. To this aim, investigationsrnwere conducted on full-glazed buildings that serve as library or office and used fixed exteriorrnshading devices as a passive means of solar control. Questionnaires, secondary data and computerrnsimulations were used to obtain quantitative data. These data were analyzed holistically to gainrnobjective results. On the other hand, shading devices of selected case buildings were adopted andrnsimulated for North, East, South, and West orientations on a mockup model to assess theirrnperformance. Their results were compared to a proposed shading design that based the identifiedrnoverheated periods. This approach yielded a horizontal, Vertical, and End-profile shading anglesrnof 820HSA, 650VSA and 380W EPA for North orientations, 650HSA, 830VSA and 600N & 550SrnEPA for East Orientations, 600HSA, 550VSA and 380W EPA for South Orientations, and 00HSA,rn350VSA and 250N & 250S EPA for West Orientations. Proposed shadings using these shadingrnangles were tested for each orientation on a mockup model. Simulation results showed an averagernshading of 57.4% North, 54% East, 75.7% South, and 84.2% West to be optimal. The results alsornshowed a monthly total direct solar heat gain reduction ranging from 63.5KWhr/m2 -rn130.9KWhr/m2 for zones facing North, 73.9KWhr/m2 - 81.4KWhr/m2 for zones facing East,rn159.9KWhr/m2 - 162.9KWhr/m2 for zones facing South, and 159.9KWhr/m2 - 108KWhr/m2 forrnzones facing West. These findings can be used as shading design guidelines for radiationrnvulnerable glazed building facades in Addis Ababa and help improve thermal comfort.
