1. Project 1:
Case study paper
Prepare by Ooi Kai Yang 0315663 Building: PJ Trade Centre

2. Research Title :
Effective of landscape design reducing heat
gain for comfort living at PJ Trade Centre

3. Research question:
1) What are the landscape design that help to reduce heat gain?
2) How does the landscape feature function to achieve thermal comfort for the
users?
3) What are the contexture architecture element in PJ trade Centre that Effective in
lowing down heat gain?

4. PJ Trade Center
Landscape
design
Passive design
-Hot climate in Malaysia cause heat gain
-Used a lot of energy to cooling but causing
heat gain
Achieve thermal
comfort
Design purpose
Courtyard / plaza with tree
-Courtyard with tall tree to catch
the ventilation
Vine
-To cover some walls from light
-To filter the hot air before pass
through
Roof Garden
-reducing the effects of
temperature
Concept Mapping:

5. PJ Trade Centre
To able understand how
landscape design function in
reducing heat gain
To be able to identify the
contextual architectural
element in PJ trade centre.
To be able to understand
what type of massing and
vegetation can be more
effectiveness to affect heat
gain.
How does the landscape
feature function to achieve
thermal comfort for the
users?
What are the contexture
architecture element in PJ
trade Centre that Effective in
lowing down heat gain?
What are the landscape
design that help to reduce
heat gain?
-Courtyard
-Vine
-Roof Garden
-Facing west
-Concrete vent block
-Cross ventilation
Landscape or vegetation can
reduce the heat reaching the
building and penetrating its
envelope by
Hot climate an non-passive
design
Research Objective
Research Question
Method

6. Landscape design :
-An integrated master landscape planning of a property or a garden design of landscape elements.
-It’s different with landscape architecture as landscape architecture is more about urban planning or a
park basically is a large scale of project.
-Landscape design not only embellish, it does affect heat gain and reducing the effect of temperature.
Effective of landscape design reducing heat gain
for comfort living at PJ Trade Centre

7. Issue: Hot climate and non- passive design

8. What are the landscape design that help to reduce heat
gain?
• Landscape or vegetation can reduce the heat reaching the building
and penetrating its envelope by increasing the reflection of solar
radiation and by providing shading.
• Landscape not only for embellish, it does affect heat gain and
reducing the effect of temperature by using tall tree, vine, roof garden
and etc.

9. How does the landscape feature function to achieve
thermal comfort for the users?
For the courtyard or plazaof PJ Trade Centre, it does have more than 1500 mature tree at there for
provide shade.
Not only provided shade, it also
filtering the hot wind

10. Vine
- Filter hot air before wind pass through ( concrete vent block )
- Insulate cushion air and reduce wind chill
- Reduce temperature
- Provide shading

11. Acros Building, Fukuoka, JapanRicola Marketing Building, Switzerland
-Well irrigated vines can result in temperatures up to 10°F cooler than the surrounding air.
-It has been calculated that a 10°F (5.5°C) reduction in the temperature immediately outside of a building can reduce the
amount of energy needed for air-conditioning by 50 to70 percent.

12. Roof Garden
Roof garden at Esplanade ( Singapore) Roof garden at PJ Trade Centre
-Roof garden, also known as green roof.
-It reducing temperature of the roof surface also able to remove heat from the air through evapotranspiration
-Provide shaded area
-Reduce energy, absorb heat and act as insulators for buildings

13. What are the contexture architecture element in PJ
trade Centre that Effective in lowing down heat gain?
Cross ventilation, make air able flow
Concrete vent block, block sun light but
wind can pass through.
PJ trade centre is facing west, when morning the sun light are block by concrete vent
block but it does able make wind pass through so it can be cross ventilation. During
noon the sun light are bock by the plant at plaza and filter the hot air before pass
through.
