COOLING LOADS ESTIMATIONS USING BUILDING INFORMATION MODELLING OF ROOM 103, ENGINEERING COMPLEX, FEDERAL UNIVERSITY OF TECHNOLOGY MINNA

Abstract

This thesis presents the modelling and estimation of cooling load of a building. The case study (Room 103, Engineering complex, Federal University of Technology, Minna) was modelled using Autodesk Revit. Building components of the case study such as walls, window, doors, floor, lights and ceiling fan had pre-installed physical properties which were easily modified and applied. A dynamic database model was created which connected the geometry such that any modification on any of the views reflects automatically on others. Estimation of the cooling load of the case study was done by applying the Cooling Load Temperature Difference (CLTD)/Solar Cooling Load (SCL)/Cooling Load Factor (CLF) method. Manual calculation of the cooling load of the case study was considered. All assumptions, equations and tabulated data were applied in accordance to ASHRAE proposals on the (CLTD/SCL/CLF) method of cooling load calculation. The calculation was based on the atmospheric condition and parameters obtainable in the month of March at active period of the day, between the 8.00h and 18.00h of the day. The calculated maximum space cooling loads are 18293W sensible and 19746W latent. A computer application was developed in Java programming language and was also used to calculate the cooling load of the case study. Results from manual calculation and results from the computer application were compare and found to be the same.
