AN APPROACH TO ENERGY EFFICIENT RETROFITTING FOR OFFICE USE BUILDING (CASE OF ARBAMINCH UNIVERSITYMAIN CAMPUS)

Abstract

As multiple studies and cases energy retrofitting is not the only way to conserve the consumption of energy used by existing building. it�۪s an imperative plug mode that enables a building track back into life and breath in the environment. developed countries commend energy codes and regulation for refurbishment of the existing building and for upcoming new constructions as compulsory requirements. Ethiopia is still rank at low level of energy infrastructure development and access to energy whereas consuming large and conserving less. In spite of that, based on the rapid urbanization and growth pattern, the rate of the built environment isn�۪t low in this country. And higher educational building is one of a hot-spots for this domino effect. Office buildings is one of the typologies in this sector, which statistically an intensive energy consuming block in every institute. Hence measurements should have to be made. As such sense this study aims to see the energy consumption pattern and contextual parameters that enforced an existing building to consume energy. Furthermore, it assessed possible best energy efficient Retrofit measures in order to establish the basis of the minimum energy Consumption and maximum occupant comfort. Quantitative research was carried out to measure the energy consumption and evaluate the energy performance of a building right after corrective measurements. Energy audit can be realized as a pre-study, then it conducts an inventory of energy loads of energy and non-energy system loads in the building. From those observations and sequential analysis, the building energy load and behavior are modeled and analyze with the help of dynamic simulation software. a contrast with the real-life energy consumption guides the study to obtain a model close to reality. In the end the study found that the case building consume huge amount of energy for artificial lighting and ventilation that can be reduced by architectural tool retrofitting. Furthermore it Recommend a conservation managements and directions on non-energy systems that influence the building for much more energy consumption. Passive retrofit design and shade design directives were also recommended
