| Summary: | Excessive usage of heating, ventilation and air-conditioning (HVAC) systems in
buildings without proper mitigation contributes to incredibly high energy consumption in
buildings, while emitting outrageous amounts of greenhouse gas (GHG) to the
atmosphere. Besides, the GHG emissions subsequently promote adverse health effects on
human being. On the other hand, the building occupants would be badly affected due to
poor indoor air quality (IAQ), and the excessive usage of HVAC system since it is not
designed to fulfil the requirements of thermal comfort of building occupants. An office
building, for example, consumes high energy due to the HVAC system, which offers the
opportunity to be studied. Therefore, an office located at the Centre for Information
Technology (IT) Development and Services, CITDS, UNIMAS was chosen as the case
study. Demand control ventilation (DCV) system has been proposed to be applied to the
existing HVAC system by utilising Carrier’s HAP simulation software. Carrier HAP is
well known for its great advantages, especially in designing ventilation and DCV system
into the existing HVAC system either for industrial or commercial buildings. The
simulation was conducted with in depth analysis in compliance with the objectives. Result
shows that the application of the DCV system feasibly reduced precisely 42.81% of the
overall energy consumption and GHG emissions to the atmosphere whilst complying with
the recommended limit set by ANSI/ASHRAE Standard 62 for indoor air quality control.
In this regard, the DCV system application is efficiently designed for the CITDS building
HVAC system. Correspondingly, it is discovered that optimum thermal comfort is
obtained while simultaneously satisfying the recommended range and limit recommended
by MS:1525. |
