=Sustainable development. =

"Development that meets the needs of the present without compromising the ability of the future generations to meet their own needs".

Two case studies in sustainable development.

 * The Nicaraguan Rope Pump. (La Bomba de Mecate). An excellent example of sustainable design and development in a developing country. This project has led to significant "south to south" technological transfer. || One area for sustainable design and development being investigated more in the west is the area of Bio mimicry. The winglets on the Airbus 380, which allow the wing span to fit in with international standards owe there design to Bio Mimicry.

This area of design and technological activity shows real promise in terms of sustainable design and development. ||

**__Sustainable building design.__**
[|Sustainable building] has a number of objectives, among them are:

 We must remember that these objectives should not only be met during the build but also during the life time of the building.
 * 1) The efficient use of all materials and resources.
 * 2) The efficient use of energy.
 * 3) Minimising all pollution.
 * 4) Harmonising the build with the environment.

 * Building envelope. || A building envelope is the separation between the interior and the exterior environments of a building. It serves as the outer shell to protect the indoor environment as well as to facilitate its climate control. ||


 * U value. || A measure of the thermal conductance of a material. The higher the U Value, the greater the conduction. ||
 * Passive solar design. || Defenition from [|greenbuilder.com]: the use of the sun's energy for the heating and cooling of living spaces. ||
 * Daylighting. || The use of natural light, usually indirect, through windows, skylights, light shelves, and other techniques that minimize glare and heat ||
 * Active solar collection. || Active solar technologies are employed to convert solar energy into usable light, heat, cause air-movement for ventilation or cooling, or store heat for future use. ||
