This document discusses various topics related to green energy, architecture, and sustainability. It outlines the major sources of green energy including solar, wind, hydroelectric, and nuclear power. It also describes the concepts of green buildings which are designed to be energy and water efficient with sustainable materials and indoor environmental quality. Additionally, it promotes the three R's of reducing consumption, recycling materials, and reusing items. The document also provides examples of green energy potential and construction practices in Pakistan. Finally, it presents several future green technologies such as seawater greenhouses, soft houses that harness solar energy, and skyscrapers with rain harvesting and geothermal cooling systems.

5. Green Energy
Advantages
• Environmental
• Economic
• Public Health and Environmental Quality

6. Green Energy
Major sources of clean energy are :
• Solar
• Wind
• Geothermal
• Biogas
• Tidal Power
• Hydroelectricity
• Compressed Natural Gas
• Nuclear Power

7. Green Architecture
• Concept of a Green building
Features:
• Energy efficiency
• Water efficiency
• Materials efficiency
• Siting and structure design efficiency
• Indoor environmental quality enhancement
• Waste reduction

8. The Three Rs: Reduce Recycle Reuse
• Reducing:
It means reducing your consumption
or buying less.
• Recycling:
Glass, paper, metal, plastic,
textiles, and electronics(e-waste) can
be recycled.
• Reusing:
Rather than throwing out items like clothing or food
jars, consumers can find new uses for them -- and thereby
reduce their consumption of new resources.

9. Green Pakistan
• Energy:
Pakistan possesses vast potential in wind, microhydel and hydel power
generation. According to a survey, the country has a total potential of
35,000 MW, which it can produce from wind power.Recently Punjab
announced that 1,277 megawatts of electricity will be generated from
10.94 million tons of biomass available from the residue of crops.
• Construction:
1. Use of high ceilings for better ventilation
2. Use of payaal
3. Use of lightweight insulated aluminium sheaths and earth bricks to
prevents buildings from heating up.
4.Use of materials such as wood, sand bricks,clay paints and ceramic tiles.

10. The Future
• Seawater greenhouses
–Incorporated in Spains Teatro del Agua
• Soft House
–Structure that harness’s energy through solar-collective
textiles
• Skyscrapers
–Will feature rain harvesting systems and
geothermal cooling systems
