• Energy efficient appliances.

• Electro-pollution and waste control.

Building:

• Foundations • Supporting structure• Slab system

Cooling:

• Passive and active cooling• Temperature control

1.Better cost:

• Reinforcement proportions

• Concrete depth

• Excavation depth

• Ease of execution

2. Better efficiency:

• Elimination of beams and associated works

• Elimination of block work infill

• Reduction of water usage during construction

• Reduction of manpower minimal waste

• Readily available and continuous platform.

3. Better speed:

• Elimination of formwork

• Fast installation of slabs

• Possibility of pre-casting on site

Passive and active cooling

1. Air-conditioning is highly energy intensive and contributes to 70% of electricity consumption in a household

2. The alternative:• Passive cooling saves energy.• Offers better quiet comfort

and energy efficiency.• Active cooling is only used at

peak periods.

Passive cooling maintains the house at a regular 25 degrees when the maximum outside temperature does not exceed 39 degrees.

• Air is extracted from wet areas

• Fresh air is introduced.

• Cooled water is circulated in tubes installed in the floors.

Active cooling only occurs when the outside temperature exceeds 39 degrees.

• Air-conditioning using chiller system is engaged.

• Mechanical ventilation is

engaged.

• System is used only at peak conditions.
