2. To reduce negative environmental impacts. To move towards more natural habitats. To reduce operating costs. To enhance building marketability. To improve inhabitant comfort. To improve living standards.

3. Using sustainable designs and operational practices. Optimizing construction cost. Reducing operational costs. Managing water and reducing waste. Using natural resources. Harvesting “free energy”

4. A green design has: Environmental benefits, Economic benefits, Social benefits, ….which affect: Owners Occupants The general public

5. Keep It: + Simple + Economical + Friendly

6. An Optimized Architectural layout: Efficient distribution of spaces. Efficient passive cooling. Local, safe and healthy materials. Careful land distribution. Efficient external works and gardens.

7. An integrated structural design: Readily available materials. Resource efficient solutions. Labor reducing concepts. Time efficient results. Cost efficient results.

8. An efficient electro mech. design: Water saving technologies. Temperature loss optimization. Integrated Passive and Active systems. Energy efficient appliances. Electro-pollution and waste control.

9. Building: Foundations Supporting structure Slab system Cooling: Passive and active cooling Temperature control

10. 1.Better cost: Reinforcement proportions Concrete depth Excavation depth Ease of execution

11. 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.

12. 3. Better speed: Elimination of formwork Fast installation of slabs Possibility of pre-casting on site

13. 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.

14. 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.

15. 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.
