Abstract
This thesis is intended to identify the design improvements of buildings that can be made for the hot region of Ethiopia. A detail literature survey is done on design improvements and those that can be most suitable and economical are suggested. A case study of two different buildings in Gode (one of the hottest area in Ethiopia) was conducted using building energy simulation software to quantify the energy saving from some of the design improvement measures such as using insulation in roof or ceiling and in walls, window glazing and shadings, and orientation. The simulation result verifies that using 75mm insulation in roof or ceilings give a better saving and most economical when the building has small glazing area with respect to the wall size and lower internal cooling load. And when the building has large glazing area using either internal or external window shading is the best way to reduce the annual energy cost of the building and 50mm roof insulation is most economical. In addition to the above results the relation between insulation and different conditions of cooling load in a building is verified. This result shows that when internal load and solar load through window are dominating insulation can have a negative impact to cooling load.
