GROUP ASSIGNMENT 1 : CASE STUDY - SUBANG PARADE
We are required to identify a building which has lift as vertical transportation system. I am in group with Jun Wei and Wai Shin, the place that we chose is Subang Parade, a building which was quite a lot of building service problems.
There are several problems that we can found in Subang Parade, two of them are lighting and fire sprinkler problems.
PROBLEM 1 – LIGHTING
Subang Parade Lighting
Recommended
Lighting Illuminance
When we
stepped into first floor of Subang Parade, we can feel that the overall
lighting is too dark, which means that it’s luminosity is not standard.
One of the
problem that caused overall lighting too dark is they are using reflected
ceiling lighting which is in yellow(warm) color. Others than that, the
quantity of lighting which will affect the luminosity of the environment too,
which means that the distance between lights is too far and illuminance of each
light is considered as too low which will make people feeling uncomfortable. Besides
that, Subang Parade using dark color carpet as the flooring material so it causes
the overall lighting much more darker compare to if they are using light colour
carpet. Recommended lighting illuminance for a supermarket or hypermarket is
around 750 lux – 1000 lux, but lighting illuminance of Subang Parade was less
than 750 lux.
The
brightness contrast of a space determines its emotional impact of a people.
Hence, individual impressions of a space are a function of brightness contrast.
So, brightness of an environment is important that will affect the flow of
people to visit it.
PROBLEM 2 – FIRE SPRINKLER
Fire
Protection & Alarm System is the most common & important facilities
that should be well maintained especially places with high flow of people.
Through this case study about Subang Parade, I found their fire sprinkler was
corrosion, which will impact the functionality of the system.
Causes of
fire sprinkler corrosion that I estimated is lack of scheduled monitoring and
inspections, corrosion of fire sprinkler systems is preventable, it occurs when
they do not conduct regular inspection of fire sprinkler system, if they do
inspection accordingly, it can correct issues before fire sprinkler corrosion
becomes a factor.
Other than
that, residual water in dry pipe systems will cause of corrosion too, oxygen
and carbon dioxide present in the pipes becomes corrosive when it interacts
with the water. For wet pipe systems, where water is always present in the
pipes, it’s trapped air that causes the problems. Oxygen interacts with the
water to create a corrosive environment that leads to breakdown over time.

After this assignment, I noticed that scheduled maintenance should be carry out in every building, to provide a safer and comforter environment for all user, especially building with high flow people. Besides that, a public space (shopping mall) with a good building service can rise the reputation too.
