Electrical energy is one of the most essential parts of our modern life. Electricity is the major
source of power for most of the country's economic and infrastructural growth. In all economic
sectors household and commercial demand for electrical energy is increasing day by day. This
demand is driven by such important factors as industrialization, extensive urbanization, population
growth, rising standard of living and even the modernization of the agricultural sector. Global
Primary energy consumption grew at a rate of 2.9% last year, almost double its 10-year average of
1.5% per year, and the fastest since 2013.
Bangladesh has a very limited energy reserve; small amounts of oil, coal and countable natural gas
reserves. . Most of our energy is supplied by fossil fuel or crude oils, both are non-renewable.
Although many alternatives such as wind, solar, geo-thermal, tidal wave and biomass energy
concepts has developed as renewable sources; no sustainable solution to reduce dependency on
fossil fuel has developed yet. The country suffers an internal energy struggle, as about 93% of the
country’s power producing thermal plants are gas-based, but the gas is also needed for the
industrial sector. Therefore, the country has to -continuously- make some compromises between
power production and developing the industrial sector. |

dc.description.abstract |
The consumption of energy has risen gradually over the year as the Urbanization happening
rapidly, so the efficient use of energy is one of the biggest concern nowadays. The built
environment is also responsible for around 40% of the global energy demand. Changes has been
made to make any commercial building more energy efficient .Understanding the use of energy in
any commercial building requires a closer insight into the amount of energy consumed and their
ways of consumption. The most effective technique to obtain such level of understanding would
be to perform an energy assessment. CSE building of Daffodil International University is an 11
storied building with a basement and perking area allocated with two lifts which is used for office
work and computer laboratories. Its commercial building but DIU using it as an academic building
in rent. The front of the building is west facing. Ground floor used as a lounge area ,level 1&2
used as classroom, level 3 to 6 made up for official work and rest of the floor made up for computer
lab. This building energy consumption 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& level 2 energy audit
to identify several energy conservation opportunities at the building. After completion of the
inspection, we are confident enough that CSE building of daffodil international university has
several no cost/low cost energy conservation opportunities it can pursue.
From December 2017 to November 2018, this building spent BDT 2836555 for electricity and
April 2017 to March 2018 they spent BDT 190826 for water, their total utility cost was BDT
3027281 .in September 2018 they used maximum electric energy and it costs BDT 448209 and in
July 2018 they used electricity which cost BDT 156525. This trend clearly shows that they misuse
the electrical energy in September 2018 but if they focused on July 2018, they must use electricity
efficiently and can continue the same practices to reduce their utility cost approximately 33.78%
of the total electricity consumption throughout the year 2018. It is anticipated that cost of electricity
will increase over time. If the cost increase the projected savings will increase correspondingly.
These savings can be re-invested in capital improvement of the building, such as replacement of
Electrical equipment to the more energy efficient equipment.it is expected that the building can
save enough money by replacing these equipment. |
