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.

R E F L E C T I O N

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.
