Urban Heat Island (UHI)

The tendency for urban areas to have warmer air temperatures than the surrounding rural landscape, due to the low albedo (ratio of solar radiation) of streets, sidewalks, parking lots, and buildings.

These surfaces absorb solar radiation during the day and release it at night, resulting in higher night temperatures.

Scheme of sustainable development: at the confluence of three preoccupations.

does not damage natural resources and which leaves the environment in good condition.

Why Sustainable

Material resources

Ecosystem (ecological system).

Energy resources RE&EE

Technology + Renewable Energy + Innovative design

= Sustainable Design = Green Design = Energy Efficient Design = Climate Responsive Design

Principles of Sustainable Built Environment

Architectural Design

1. Climate conscious & responsive design

Climate conscious design requires

a) a thorough understanding of the local climate, and

b) employment of several strategies and systems for the creation of an agreeable micro-climate with a minimal investment of energy.

The success of such a design depends as much on

the integration of these strategies and

the proper operation of the building by its users

Principles of Sustainable Built Environment

Architectural Design

2. Achieving Comfort

Human comfort is a prime objective for any building design.

To achieve indoor comfort depend very much on the ability of the design team to exploit available outdoor climatic element appropriately.

Principles of Sustainable Built Environment

Architectural Design

3. Sustainable resources

Sustainable materials

Selection of building materials which does not treat the natural resources, particularly species which is endangered.

Sustainable energy

There are two types of energy; Renewable and non-renewable.

Priority should be given to use renewable energy. If non-renewable is to be used, use wisely implement Energy Efficiency practices.

4. Low energy

Low energy building concept is becoming Important and crucial to be implemented.

Low energy building means;

Use less energy & electricity generated from fossil fuel power plants.

Generate own energy & electricity via renewable technologies such as PV & solar heating.

Principles of Sustainable Environmental

5. Environmentally sustainable

Implement 3R;

Reduce,

Reuse,

Recycle.

6. Economically viable

Economic viability is a key to the success of any new architectural design solutions.

Sustainable Architectural design sometime require additional capital, however if the technology is able to prove substantial savings in reasonable time frame, it is consider economically viable.

Usually the terms used is ROI (return of investment) of Pay back period.

Sustainable Architecture

Several terms can be associated with SA;

Climatic Architecture

Bioclimatic architecture

Sustainable design

Sustainable design

is the art of designing physical objects to comply with the principles of

economic,

social, and

ecological sustainability.

designing

small objects for everyday use,

designing buildings,

cities, and

the earth's physical surface.

Examples of sustainable design

1. Green buildings conserve energy, water and resources with

limited polluting of either indoor or outdoor environments.

2. autonomous buildings use available resources such as rainwater,

solar power or wind turbines, in order to reduce their dependence on fossil fuels and other resources.

3. can be constructed of recycled materials as well, reducing their total

energy requirements for construction.

Sustainable Architecture

Architecture which does not damage natural resources and which leaves the environment in good condition.

Environmental sustainable architecture

Environmentally friendly architecture is based on the following five principles:

1) healthful interior environment;

2) energy efficiency;

3) ecologically benign (kind) materials;

4) environmental form;

5) good design.

Design Approach

During the design phase: It integrates all the sub-systems and parts of the building must fit and work together.

It is essential that the design team (architects, engineers, building occupants and specialists in areas such as indoor air quality, materials, and energy use) be fully integrated from the beginning of the process.

Climatic Architecture Design Strategies for

Sustainable Environment

Design Process

The design process takes into consideration the building structure and systems as a whole and examines how these systems work best together to save energy and reduce environmental impact.

Considers site, energy, materials, indoor air quality, acoustics, natural resources, and their interrelation.

Climatic architecture

aims to use climatic resources to reduce spending on energy for heating, cooling and lighting of buildings,

with a view to providing a comfortable atmosphere :

thermal comfort summer and winter,

lighting comfort,

respirator (breathe) comfort.

General Concept of Climatic Architecture

General Concept of Climatic Architecture

Climatic architecture

is a way of designing buildings and manipulating the environment within buildings by working with natural forces around the building rather than against them.

concerns itself with climate as a major contextual generator, and

with benign (kind) environments using minimal energy as its target.

Why Climatic architecture is significant ?

use and exploit available free energy from environment.

EE means less energy consumption less energy cost less environmental problem due to the burning of fossil fuels for electricity generation.

Climatic Architecture Design Strategies for Sustainable Environment

Principles of Climatic Architecture in

Tropical Climate

1. Passive solar Passive solar is a term referring to those technologies that

can be employed to convert sunlight into usable heat, to cause air-movement for ventilation or cooling, or to store the heat for future use, without the use of much or any electrical or mechanical

equipment.

Principles of Climatic Architecture in

Tropical Climate

1. Passive solar Passive solar technologies include

direct gain and indirect gain for space heating, use of thermal mass and phase-change materials for dampening indoor air

temperature swings, the solar chimney for enhancing natural ventilation, and earth sheltering. solar water heating systems based on the thermo

siphon, solar cookers,

Principles of Climatic Architecture in

Tropical Climate

Passive solar design techniques; Building position

Based on the local climate and the sun's positioning

the entire building can be positioned and angled to be oriented towards or away from the sun (according whether heating or cooling is the primary concern),

overshadowing from other structures or natural features can be avoided or used, and

the building can be set into the ground using earth sheltering techniques.

Principles of Climatic Architecture in

Tropical Climate

Passive solar design techniques (cont.);

Building properties

The shape (and consequently the surface area) of the building can be controlled to reduce the heating or cooling requirement, and

the use of materials properties to reflect, absorb, or transmit energy (for example using visible color) is also a consideration.

External environment

Energy-efficient landscaping materials, including the use of trees and plants can be selected to reflect or absorb heat,

create summer shading (particularly in the case of deciduous (temporary) plants), and create shelter from the wind.

Tropical Climate

2. Active solar

Is a term referring to those technologies that can be employed

to convert solar energy into usable heat,

to cause air-movement for ventilation or cooling,

or to store the heat for future use,

The use of electrical or mechanical equipment, such as pumps and fans, to facilitate this.

Conclusion

Passive solar systems rules of thumb:- The building should be elongated on an north-

south axis. The building's elongated face should not receive

direct sunlight between the hours of 9:00 A.M. and 3:00 P.M. to prevent direct heat radiation from the sun.

Interior spaces requiring the most light during day time - to receive most natural lighting and natural ventilation -the spaces should be located along the parameter wall of the building.

Less used spaces should be located in the middle of the building.

An open floor plan optimizes passive system operation.

Use shading to prevent direct sun radiation entering the interior.
