This document discusses passive design strategies to reduce heat gain in tropical box houses. It describes how egg crate structures and vegetation provide shading to reduce heat. The building layout and large openings help maximize cross ventilation. Passive designs like these use ambient energy sources instead of electricity to create a comfortable indoor environment while reducing energy usage and costs.

QUESTION 1
How does egg
Crate structure
and vegetations
aid in shading
to reduce heat
gain in Tropical
Box House ?
QUESTION 2
How does the
building layouts
and openings
help in
ventilation to
reduce heat
gain in Tropical
Box house?
QUESTION 3
What are the
other strategies
used by
Tropical Box
House to
reduce heat
gain ?

4. PASSIVE DESIGNS
Passive design strategies use ambient energy
source instead of purchased energy like electricity
or natural gas.

5. PASSIVE DESIGNS
Passive design strategies include
1. Day lighting
2. Passive Heating
3. Passive Cooling ( Ventilation and Shading)

6. IMPORTANCE
PASSIVE DESIGNS
1. More energy efficient
2. Creating a comfortable environment to live and
decrease the usage of mechanical means.
3. Reduce environment impact
4. Reduce capital and operating cost

7. PASSIVE SHADING
1 . EGG CRATE SYSTEM
2 . VEGETATION

8. EGG CRATE SYSTEM

9. EGG CRATE SYSTEM
Selection of Egg Crate system as
the passive shading device which
are facing North-East and South-
West to keep the heat out but
draws only daylight in to create
comfortable space

10. EGG CRATE SYSTEM
Large roof eaves for
effective sun shading
Egg Crate System Malay Vernacular Large roof eaves
-Thickness of the egg crate system
act as sun filtering device which
naturally allows daylight to pass
through but filter radiation.
-Large roof eaves to shades the
building from sunlight

11. VEGETATION

12. VEGETATION
Trees and shrubs are a very
effective means of improving the
climate on a larger scale. They are
the simplest way of shading
outdoor space and buildings.
One simple solution for regulating
shading by trees throughout the
year is the use of high trees

13. VEGETATION
High trees with wide, shading crowns provide significant protection from solar
radiation and should be incorporated as much as possible into any landscape
planning creating a comfortable microclimate

14. PASSIVE VENTILATION
1 . BUILDING LAYOUT
2 . OPENINGS

15. BUILDING LAYOUT

16. BUILDING LAYOUT
South- West Wind
( May – September )
North- East Wind
( November - March)
South wind
( Throughout the year)
The building orientation of the Tropical Box House suits the
direction of the wind to maximize the natural ventilation

17. BUILDING LAYOUT ( OPEN PLAN )
Open layout plan of Tropical Box House which connects the social place such as
open deck, dining area, kitchen and lounge aids in maximize the ventilation as
there is no obstruction
OPEN DECK, DINING , KITCHEN , LOUNGE

18. OPENINGS

19. OPENINGS ( EGG CRATE)
Fully open
able windows
allow
ventilation at
body level
The Malay
vernacular
architecture
-Fully open size
windows
Tropical Box
House
-Large openings
from the egg crate
system
BOTH GOOD FOR
VENTILATION

20. OPENINGS ( NO FACADE )
The south part of the Tropical Box
House is not covered
-This allow the maximum natural
ventilation from south and south-
west wind.
-Directly ventilate the social spaces,
open deck, dining, kitchen and
lounge.
OPEN DECK, DINING , KITCHEN , LOUNGE

21. OPENINGS ( CROSS VENTILATION )
The uncovered south
part of Tropical Box
House create cross
ventilation across the
house
