| dc.description.abstract | Having Conditioned air is a non questionable comfort issue for both commercial and residential buildings. To do so there should be a specified air condition requirements for air conditioning design so that the required comfort will effectively be attained. Specifying the local or national air conditioning requirements is the only way to effectively attain the human comfort while constructing any building. The main intension of this paper is to specify the air conditioning requirements based on local or national data. Mainly the cooling load in w/m2 which is the main parameter for AC design is determined for representative areas of Ethiopia using the HAP software. These selected representative areas are at different temperature zones. These are Addis Ababa for moderate temperature, Bahir-Dar for warm temperature, Dire-Dawa for hot temperature, and Semera for very hot temperature. While doing this paper first the weather data for the selected areas of Ethiopia are collected from the National Metrology Agency. Also the architectural data or floor plans are gathered for each representative room types. Then all the data are entered in to the soft ware and analyzed by keeping some parameters like relative humidity as a checking point for comfort conditions. Finally the main AC design parameters are specified. Mainly the cooling load in w/m2 for all representative areas of the country is specified for rooms of various applications. The results show that the air conditioning design for commercial buildings depend on many factors. These are geographical locations, orientation of the building, types of applications to which the building is used for, number of population, the floor to which the room is located and the material to which the building is made. In general it is observed that north oriented buildings have lower cooling load in relative to other orientations. And the cooling load is specified for based on north orientation. And also other parameters have their own effect on the effective design of the room from AC perspective. Hence it is recommended for the air conditioning designers of the commercial building to use these local or national standards in which the above factors are considered and to have an effective air conditioning system. | en_US |
