Abstract
This paper investigated and recommended possible solutions to the high electricity consumption of a public sector
organization. The activities of the organization include managing database and information systems and host a
number of training workshops in the course of the year as part of its core activities. A hybrid of a walkthrough and
standard energy audits were conducted in the organization in September 2009 with the full implementation date in
March 2010. This involved the visual inspection of the building, cataloguing of the electrical appliances and the
installation of energy monitoring meters on selected electrical equipment of the building. The main segments of
energy consumption in the organization were on its lighting systems, computers and accessories, and air
conditioners. The total instantaneous power consumption in the building was 79.38 kW, with the highest
consumption of energy being from lighting (48%) followed by air conditioners (24.1%) and then computer and
accessories (10.1%). Measures on energy conservation were recommended based on the audit. The follow up visit in
February 2011, it was realized that electricity consumption by the end of 2010 had dropped by 46% equivalent to
29% of cash savings in spite of tariff increase of 42% in June 2010
