CHAPTER 1
INTRODUCTION
1.0 BACKGROUND
The project tries to find ways on reducing the energy consumption of the ACMV air- conditioning and mechanical ventilation system of the FKM building.
Air Conditioning is the control of the humidity of air by either increasing or decreasing its moisture content. Added to the control of the humidity is the control
of temperature by either heating or cooling the air, the purification of the air by washing or filtering the air and the control of the air motion and ventilation.
Ventilation refers to the process of supplying and removing air by natural or mechanical means to and from any space, Such air may or may not be conditioned.
Building energy standards or codes are becoming more and more important in energy efficiency policies [1]. These standards can help raise concern and awareness
of building energy conservation, promote energy efficient designs in buildings, encourage the development of energy efficient building products, and form a basis
for assessing building energy performance and developing energy efficiency programmers [2]. Many countries in the world are now developing or upgrading their
building energy standards in order to achieve the energy efficiency goals. In response to broad concerns regarding the environment and climate change,
Green Buildings are becoming much more common and are increasingly in demand by building owners and occupiers [3]. As a result, they are featuring more
prominently in the portfolios of most building developers, architects and engineering consultants. The current green trends are quickly becoming the new standard.
