Global warming is caused by an increased amount of heat from the sun being trapped in the atmosphere rather than radiated out into space. Major contributors include coal-burning power plants, airplanes, traffic, agriculture, and buildings used for living, working and shopping. Green architecture aims to minimize environmental harm through eco-friendly materials and construction practices. It focuses on passive cooling, energy efficiency, alternate power sources, reuse of existing structures, efficient space use, local materials, rainwater harvesting, and reducing waste. Some passive cooling methods for tropical climates include building orientation, ventilation, facade design, and insulation. The Bahrain World Trade Center harnesses wind power through huge on-site wind turbines.

2. GLOBAL WARMING
The slow increase in the average
temperature of the earth’s atmosphere
because an increased amount of the heat
striking the earth from the sun is being
trapped in the atmosphere and not
radiated out into space.

CULPRITS OF GLOBAL WARMING
• Coal-burning power plants
• Airplanes
• Traffic-clogged highways
Agriculture is the second most important source
(animals – cows and pigs), feed production,
chemical intensive food production, flooded
paddy rice production, as well as deforestation
driven by the desire to expand cultivated areas
and the fumes from nitrogen-rich fertilizers and
animal waste that combine in the air with
industrial emissions.

CULPRITS OF GLOBAL WARMING
The places we live, work, study and shop.
Most of the average building's emissions come
from everyday needs: to warm and cool our
environment, provide light, cook food and
surfing the internet.

7. WHAT IS
GREEN ARCHITECTURE?
Green architecture, or green design, is
an approach to building that minimizes
harmful effects on human health and
the environment. The architect attempts
to safeguard air, water, and earth by
choosing eco-friendly building materials
and construction practices.

8. 1. Ventilation systems designed for efficient cooling
The Philippines has Tropical Climate (Hot-humid)
TROPICAL DESIGN PRINCIPLE- maximize the wind,
minimize the sun
GREEN ARCHITECTURE CHARACTERISTICS
Amihan (NE) – November to April Habagat (SW) - May to October

9. PASSIVE COOLING
A cooling system using a building’s design and
construction to maintain a comfortable temperature
within the building
Some passive cooling methods used in building design
1. Building configuration, site layout and site planning
2. Building orientation

10. Some passive cooling methods used in building design
3. Facade design
4. Wind and natural ventilation
Use of Double-layered façade Use Low-emissivity glass
(Low-E glass)
Use of Insulation

11. 2. Energy-efficient lighting and appliances
3. Alternate power sources such as solar power
or wind power.

12. 4. Adaptive reuse of older buildings and use of
recycled architectural salvage
5. Efficient use of space
6. Locally-obtained materials
7. Rainwater harvesting
While most green buildings do not have all of
these features, the highest goal of green
architecture is to be fully sustainable. Simply put,
you do "green“ things in order to achieve
sustainability.
8. Reduce, Reuse and Recycle waste

13. One of the world's most sustainable buildings
Bahrain World Trade Center, Manama, Bahrain

Three huge wind turbines – 29 meters in
diameter– are sandwiched between two vast
'sail' shaped towers, generating clean energy
for the building.
