WHAT IS SUSTAINABILITY

It is the capacity to endure.

The word is derived from the Latin sustinere(tenere, to hold; sus, up). The word sustain:tomaintain", "support", or "endure

"Meeting the needs of the present withoutcomprising the ability of future generations tomeet their own needs."

___Bruntland Commission of United Nations

"Sustainability is improving the quality ofhuman life while living within the carryingcapacity of supporting eco-systems."

___IUCN/UNEP/WWF (1991)-Caring for the Earth

Sustainability has become a wide-ranging term thatcan be applied to almost every facet of life on

Earth, from a local to a global scale and over

various time periods.

As the earths human population has increased,natural ecosystems have declined and changes in

the balance of natural cycles has had a negative

impact on both humans and other living systems.

There is now abundant scientific evidence that

humanity is living unsustainably. Limited energy resources

Green house effect Ozone depletion

Returning human use of natural resources to

within sustainable limits will require a major

collective effort. Ways of living more sustainably can be in many

forms; reorganising living conditions (e.g., ecovillages, eco-

municipalities and sustainable cities)

reappraising economic sectors (permaculture, greenbuilding, sustainable agriculture)

re appraising work practices (sustainable architecture)

using science to develop new technologies (greentechnologies, renewable energy)

adjustments in individual lifestyles

SUSTAINABLE DESIGN


6/20

SUSTAINABILITY IN ARCHITECTURE

Sustainable building design involves the

considered and logical evaluation of a

buildings life cycle impact in terms of

environmental pollution and resource

depletion. By the application of rational andsystematic design policies and strategies, it

aims to reduce that impact to levels that are

within the capacity of the environmental,social

and economic support systems on which thebuilding is dependent to manage without

adverse affect on other life forms or their

support systems.

During a buildings existence, it affects thelocal and global environments via a series ofinterconnected human activities and natural

processes. At the early stage,

site development and construction influenceindigenous ecological characteristics.

the influx of construction equipment and personnelonto a building site and process of construction itself

disrupt the local ecology. the procurement and manufacturing of materials

impact the global environment.

Once built, building operation inflicts long-lasting impact on the

environment. For instance; the energy and water used by its inhabitants produce

toxic gases and sewage; the process of extracting, refining, and transporting all

the resources used in building operation andmaintenance also have numerous effects on theenvironment.


8/20

As a societys economic status improves, its

demand for architectural resourcesland,

buildings or building products, energy, and

other resourceswill increase. This in turn

increases the combined impact of architectureon the global ecosystem, which is made up of

inorganic elements, living organisms, and

humans.

The goal of sustainable design is to findarchitectural solutions that guarantee the well-being and coexistence of these threeconstituent groups.

SUSTAINABLE DESIGN PRINCIPLES

Sustainable design principles include but are not

limited to: Increase in energy and water efficiency and

conservation;

Increase in use of renewable energy resources;

Reduction of elimination of toxic and hazardous

substances in facilities, processes and their surrounding

environment;

Improvement of indoor air quality and interior and

exterior environments leading to increased human

productivity and performance and better human health; Use of resources and materials efficiently;

Selection of materials and products that would minimize

safety hazards and cumulative environmental impacts;

Increase in use of recycled content and other

environmentally preferred products;


10/20

Salvage and recycling of construction waste and

building materials during construction and during

demolition;

Prevention of the generation of harmful materials and

emmissions during construction, operation and

decommissioning/demolition;

Implementation maintenance and operational

practices that reduce or eliminate harmful effects on

people and the natural environment;

Reuse of existing infrastructure, locate facilities near

public transportation; Consider redevelopment of contaminated properties.
