What led to the emergence of cities. Technological advances: agricultural techniques, construction, smelting of metals Higher productivity in agriculture Food surplus sufficient to feed non-farmers, i.e. craftsmen, traders, soldiers, warfare,religious leaders, politicians Increased geographical mobility and diffusions of goods, technologies, ideas Concentration of population: trade hubs, political centers and massive public projectsdrainage and irrigation Occupational diversity and specialization interdependence Some functions/skills are more "important" than others complex social organizationand hierarchy Cities as centers of imperial power

Cities as cultural centers: literacy, arts, religion, science City and the countryside: First-political, then also economic domination of cities overrural areas

The building process: life cycle and energy use


14/33

A building during its lifetime consumes energy in manyways

1. Embodied energy2. Grey energy

3. Induced energy

4. Operating energy


15/33

Embodied energy


3. Induced energy

Energy consumed in the manufacture of building materials


16/33

Grey energy


3. Induced energy

Energy used in the transporting materials andcomponents from places of extraction and manufactureto the building site


17/33

Induced energy


3. Induced energy

Energy used in the construction process


18/33

Operating energy


3. Induced energy

Energy consumed in the running of a building


19/33

Operating energy

Operat ing energy is a s ignif icantmeasure of sustainability which enablesstraightforward comparisons betweenal ternat ive bui ld ing technologies .

Buildings consume energy for heating,

cooling, ventilation, lighting, equipmentand appliances. Passive energy systemsrely on the building enclosure orenvelope to take advantage of naturalenergy sources such as sunlight, wind,water, and the surrounding soil. Activeenergy systems represent mechanical,electrical and/or chemical processes.

CARBON EMISSIONS


23/33

THE HIGH THERMAL MASS BUILDING

Absorbs and releases heat on a daily cycle(particularly when diurnal ranges are high)

Optimization of orientationBalancing shading and sun trappingInsulation


24/33

Sustainable construction

Sustainable construction is defined as "the creation and responsiblemanagement of a healthy built environment based on resourceefficient and ecological principles". Sustainable designed buildingsaim to lessen their impact on our environment through energy andresource eff iciency. I t includes the fol lowing principles:

- Minimizing non-renewable resource consumption. - Enhancing the natural environment

- Eliminating or minimizing the use of toxins

-Conservation (Recycle Re-use Reduce)


25/33

LOW ENERGY BUILDING

Add to that the issue of renewableenergiesEnvironment friendly materials andconstruction

And importantly occupants comfort


26/33

OTHER CONCURRENT TERMS NEEDED TO BE

USED FOR LOW ENERGY:

Passive solar buildingGreen buildingLow carbon buildingEnergy conscious design

Etc.


27/33

BUILDING NEEDS TO BE BALANCED

Reduce excessive solar gain in summerUtilizing solar radiation in winter (more for cold climates)

Allow daylight but avoid glareNaturally ventilated without being windyMay be required to seal the building to conserve heat orcool

Like a living entity constantly adjusting to nature


28/33

THE BIO CLIMATIC BUILDING

Building inspired by natureWith a clear strategy for minimizingenvironmental degradation

BIO + CLIMATICNatural systems + climatic regimeinteractingTo produce comfortable spaces in harmonywith nature


29/33

DO NOT EXPECT FROM E RTH TO PRODUCE

MORE

DO MORE WITH WH T E RTH PRODUCES

CONCLUSION

To serve every potential eco-aware consumer inimplementations, trained human resources areessential, where the joint role of investor, designerand academics could be enormous.

Ultimately it could provide the incentive formotivation, design innovation, integrity, efficacy,courage and reliability for the growing youth forceof the country.
