Energy Audit Report

Abstract

The demand for energy has risen astronomically over generations and as of today, efficient use of energy becomes a major concern. The built environment is responsible for 40% of the global energy demand. Changes have been made to make buildings more energy efficient. Understanding the use of energy in buildings requires an insight into the amounts of energy consumed and their ways of consumption. The most effective technique to obtain such level of understanding would be to perform an Energy Audit. Daffodil International University (CSE Building) is a 10 storeyed building with a basement and parking area and allocated with two lifts which is used for office work and Computer Laboratories. This Building facing towards west side. Later they made changes of the plan inside the building for their own. Ground floor basically a lounge area, level 1&2 classroom, level 3 to 6 made up for official work and 7 and above made up for lab room. This building is based on 100% electricity and water. No Gas is used in this building. As part of the Building Master Plan our team conducted an ASHRAE Level 1 Energy Audit to identify several energy conservation opportunities at the building. Upon completion of the inspection, we are confident that the Daffodil International University (CSE Building) has several no cost/low cost energy conservation opportunities it can pursue. These opportunities will support the Building’s economic benefit to the region and are summarized in this report. From December 2017 to November 2018, this building spent BDT 2836555 for electricity and April 2017 to March 2018 they sent BDT 190826 for water, their total utility cost BDT 3027381. In September 2018 they used maximum electric energy and it costs BDT 448209 and in July 2018(During the Semester) they used electrical energy which costs BDT 156525. This trend shows that they misuse the electrical energy on September 2018 but if they focused on July 2018, they must use electricity efficiently and can continue the same practices to reduces their utility costs approximately 33.78% of the 2018 electric consumption or approximately BDT 958188.28. It is anticipated that the cost of electricity will increase over time. If the cost of electricity increases, these projected savings will increase correspondingly. These savings are based on the current cost of electricity.
