INTRODUCTION
An eco-city also known as sustainable city.
Designed - environmental impact, inhabited by people dedicated to minimization of required inputs of energy, water and food, and waste output of heat, air pollution - CO2, methane, and water pollution.
term "eco-city" - 1987 book, Eco-city Berkeley: Building Cities for a Healthy Future by Richard Register
It should meet the needs of the present without sacrificing the ability of future generations.
A sustainable city should be able to feed itself with minimal reliance on the surrounding countryside, and power itself with renewable sources of energy.
Practical achievement
Different agricultural systems - agricultural plots within the city – reduces distance.
Renewable energy sources - wind turbines, solar panels, or bio-gas created from sewage.
methods to reduce air conditioning - planting trees and lightening surface colors, natural ventilation systems, an increase in water features, and green spaces equaling at least 20% of the city's surface.
Transportation planning- Improved public transport and an increase in pedestrianization to reduce car emissions - requires a radically different approach to city planning.
Optimal building density - make public transport viable - avoid the creation of urban heat islands.
ARCHITECTURE
Buildings provide the infrastructure for a functioning city and allow many opportunities to demonstrate a commitment to sustainability. A commitment to sustainable architecture encompasses all phases of building including the planning, building, and restructuring, and building.
Eco-industrial Park
Industries connect a number of firms -work together - decrease their environmental impact & improving their economic performance.
include natural systems, more efficient use of energy
accomplished through plant design, landscaping, & choice of materials.
Urban farming
process of growing and distributing food, as well as raising animals, in and around a city
this method of food cultivation saves energy in food transportation and saves costs
Individual buildings (LEED)
LEED, or Leadership in Energy and Environmental Design, is an internationally recognized green building certification system.
In order for a building to become
LEED, certified sustainability
needs to be prioritized in design
construction and use.
Transportation
sustainable transportation attempts to reduce a use of greenhouse emitting gases by:
eco friendly urban planning, low environmental impact vehicles, to create an urban center that has greater environmental responsibility and social equity.
