Green Building Concept ( Smart & Cool Technology)

What¶s Smart & Cool technology?

The idea behind the patented Smart & Cool technology is to reduce the temperature inside the

house, subsequently minimising the use of the air conditioner and cutting down energy

consumption, while maintaining the visual of a modern house.

Lee claims that his technology reduces the temperature of a house from 6 ± 9 degree Celsius.

There are four methods used to keep the house cool and they are implemented during the

construction process. First is the substructure (the foundation), which is made up of discarded

car tyres.

Tyres arranged as foundation of building.



» Car tyres are conductors. We use them as a heat sink for the buildings to absorb heat

from its surrounding.

» corrugated upper floor slabs. The corrugation method increases the strength of the

floor slab. This technique allows the floor slab structure to be less thick as there is no

need to pile it up with concrete and steel. As a result, the weight of the building is

reduced.

» The corrugated concrete slab increases the surface area, which also means it increases

the effectiveness of the upper floor slab to absorb the heat build up inside the building

and transports the heat down to the tyre foundation through the walls.

» The walls and partitions of the house are made of lightweight foamed concrete blocks.

» Not only do the concrete blocks make the building lighter but it also assists in

transferring heat down to the tyres, especially heat from the higher floors of the

building.

» The lightweight blocks have a thermal-insulating property that slows down theabsorption of heat from the building¶s external surroundings. This provides ample

time for the tyres to absorb heat from the walls.

» The final technique is the Venturi Action Roof system, which is installed just below

the roof tile. This system immediately removes hot air by creating an artificial air flow

channel that prevents the trapped heat in the rooftop to transfer into the building.



Why ³SMART´ ?

o Cost efficient (construction cost, energy cost)

o Reduce (material use, labour content, time, waste, formwork)

o Reuse (Formwork)

o Recycle (Discarded tyres)

o Healthy living ( No heat stress)

o Higher quality house (accurate & fine construction)

o Ideal for BIPV (faster ROI)

Why ³COOL´ ?

o Built not to keep the heat in, but to absorb-cum-conduct the heat away

o Heat through the roof taken away by the venturi -action of cold air pushing heated air

up through the space under the roof in parallel with insulated ceiling; no hot air

trapped under the ceiling

o The heat captured in the walls would find its way to cooler points created by having to

introduce waste-rubber tyres laid systematically in the works below ground, as ³heat

sinks´, to absorb and to conduct the heat away, deeper into cooler grounds.

Energy Eff icient

» Low indoor ± air temperature

- Can live wihtout air cond

- Energy saving

» Even if air-con is used, air is cooler faster because whole house doesn¶t retain heat( No

need to cool the walls).

» Indoor cool air stays cool longer
