IMPACT OF ENERGY MANAGEMENT ON ENERGY CONSUMPTION IN COMMERCIAL OFFICE BUILDINGS A COMPARATIVE STUDY OF THE COCA-COLA COMPANY's HEAD OFFICE AND THE VICTORIA TOWERS BUILDINGS IN UPPER HILL.

ABSTRACT
Energy is one of the main drivers of all natural and man-made processes. Energy as a resource is the most paramount to maintenance of life on earth and is behind all production, manufacturing,industrial and commercial processes which have a direct impact on human lives. Energy demand has been on the rise over the years while supply has been on a static state, the rate of increase of demand for energy has been greater than the rate of increase of supply of energy. As a result there has been an increase in the cost of energy With increase in commercial development in the Kenyan construction industry, more and more energy is needed on the backdrop of high cost of energy. In view of this, there is need for managing energy use in the commercial building so as to reduce the buildings energy consumption. The objective of this research study was to establish the relationship between energy management and energy consumption in commercial office buildings, identify the energy aspect that has the largest potential of reducing energy consumption in commercial office building and identify the energy management techniques most suitable in office buildings. To achieve this comparative study approach was adopted in Coca-Cola Company building and Victoria Towers in upper hill. From analysis of the data collected a positive relationship was established, artificial lighting and telecommunication and office equipment have the largest potential in reducing energy consumption and use automatic systems was the most suitable energy management techniques in office buildings. The study recommended that building owners, managers and organizations should incorporate energy management practices, conduct periodic energy awareness and energy use training seminars and ensure energy audits are conducted to assess the energy consumption of each system and results of the audit made available to all building occupants.
