Arch 213: Ecological Issues in Architecture

-Eco-Design Awareness-

Assist. Prof. Dr. Harun SevinçAssist. Prof. Dr. Pınar Uluçay

People’s needs / towards new technologies

New needs lead us to invent new technologies to develop the existing conditions of the world.

• This development affects the environment in some negative ways.

• Changing the ecological balance endanger the human life accordingly

Architecture is one of the most effective professions that has power to change the natural environment.

•Architects design buildings, so that every year lots of buildings are constructed..........

•And these buildings

occupy a big amount of land area, diminish natural resources,cause environmental pollution.

Saving the environment is an urgent issue:

• to maintain the natural life in consideration

with

• natural and built environment relationship.

Architect’s role & responsibility

• To care for the environment is depending on:

• The architect is consciouson the design principles

in order to approachthe new way of design.

At the beginning of 21st Century

• The significance of green issues in all fields.

• Awareness has raised in various aspects

from very broad environmental, physical concerns to more social, humanistic, spiritual concerns

• even in macro (urban) / micro (object) levels.

However, STILL……

• the ecological thought has already been a virgin field

developed in various research areas, the intersection of these two broad subjects

from 'the Mother Earth' to the 'Human Being‘

should be

• the core of all disciplines that point of view.

The aim of this talk is to enable architects to feel responsible in the earlier stages of their professional life

• the Ecological Design Issues• Ecological / Green / Bio-climatic / Healthy / Environmental Friendly Building Design

in their future designs and practices

At the second stage of the talk

• the effect of green thinking in architectural education

Ecological considerations

General Issues in the field “Thoughts on the habitability of the planet”

• Population explosion• Consumption patterns of human being/ how the planet has been changed by humans?• Any kind of pollution started…• Earth’s resources getting limited and changes:

Earth / soil / losing forestries…Water / fresh water/ melting icebergs…Air /atmospheric conditions; ozone layer depletionFire / fuel oils reserves lessening..

Terms, terms, terms…

• Ecological

• Sustainable

• Green

• Eco-friendly

• Bioclimatic

• Healthy -buildings (sick building syndrom)…

• Building biology

The emphasis is given by living & non-living organism of the world resources

• Ecology(n) Ecological(adj)

Natural fields Science Substantiality Facts Realities Objective variables Material resources Energy matters Quantitative research The Earth

Eco-nomy and Eco-logy• 'Eco' derives from greek ‘oikos’ and means 'the art of managing a house or household'.

• Ecology embraces the totality of the relationship with the living environment, whereas economics is concerned with the management of the community's resources.

• This design importantly recognises these two meanings of Eco –house

that of an environmentally appropriate dwelling, an economically acceptable dwelling.

Research Methods and levels varies by the term of sustainability apply nearly all fields..

• Sustainable (adj): long-lasting Sustainability (n)

Abstractivity• Generalizations• Abstractions Subjective variables• City / urban situations• Community based issues, Qualitative research• Events, phenomena, happenings• Laws, rules• Politics, democracy, rights• Professional Agreements, Summits, applications all over the world

Green is… may be a more flexible and balancing term• Equalising….

the abstract meaning of the environment with the substantial side of the planet could be related to more green philosophy, green psychology or green movement of the politics..

to make them more stable in their own coordinates.

•Efficient resource use–•High density, and identification with building and place and nature it to be encouraged.

• The designer to explore a combination of a limited self-build

which could reduce costs under a contractor’s guidance, provide knowledge to the occupant to carry out on-going maintenance and to construct future additions, together with rent to buy as the means of ownership.

• This level of occupier control over their environment, intellectual and economic, would engender true attachment to site, house and nature.

Eco - principles in designing of a building

• Concerning energy

• Working with climate

• Minimizing of new resources & economical use of existing resources

• Respect for the user (needs, culture..)

• Design with the site context

Making green / ecological evaluation of existing buildings

• Aims

Examining how can we change existing buildings in terms of ecology

How is the potentiality of being ecological among existing buildings / vernaculars?
