SMART SUSTAINABLE CITY PLANING

A sustainable city, or eco-city is a city designed with consideration of environmental impact, dedicated to minimization of required inputs of energy, water and waste. Output of heat, air pollution - CO2, methane, and water pollution.

A sustainable city can feed itself with minimal reliance on the surrounding countryside, and power itself with renewable sources of energy. The crux of this is to create the smallest possible ecological footprint, and to produce the lowest quantity of pollution possible, to efficiently use land; compost used materials, recycle it or convert waste-to-energy, and thus the city's overall contribution to climate change will be minimal

Ecological sustainable cities are achieved through various means, such as:

Renewable energy sources, such as wind turbines or solar panels. Cities provide economies of scale that make such energy sources viable.
Various methods to reduce the need for air conditioning (a massive energy demand), such as planting trees and lightening surface colours ( white roofs), natural ventilation systems, an increase in water features, and green spaces equaling at least 20% of the city's surface.
Improved public transport and an increase in pedestrianization to reduce car emissions. This requires a radically different approach to city planning, with integrated business, industrial, and residential zones. Roads may be designed to make driving difficult.
Solutions to decrease urban sprawl, by seeking new ways of allowing people to live closer to the workspace since the workplace tends to be in the city, downtown, or urban center, they are seeking a way to increase density by changing the antiquated attitudes many suburbanites have towards inner-city areas.
Green roofs, the holistic vision speaks of a city surrounded by greenery and clean air, a cost-effective city that consumes no exorbitant energy resources but can sustain its own energy needs, the city of green gardens, clean water and ecological balance in and around it. A green roof or a protective roof is a vegetation roof that is applied by laying an infrastructure that allows the holding of nutrients and water to the vegetation and protection of the structure from penetration of roots and liquids.
Thermal insulation - the ground layer on the roof prevents its flare as a result of direct sunlight, so a protective roof reduces the demand for air cooling on the floor under the roof and to save about 20% of the electricity expenditure.
Acoustic insulation - the protective substrate isolates environmental noise caused by the movement of cars and aircraft, to the point of reduction of About 8 decibels.
Biodiversity - A green roof is a biosphere that invites birds, butterflies and other animals. It helps preserve the city's natural sense and enrich biodiversity.
Suspension of runoff water and reducing the load on the drainage systems in the green roof peak behavior acts as a permeable area of the runoff. A rating is created for the arrival of rain water to the drainage systems, the load on them is reduced and the flooding and collapses are avoided.
Roof filtration filters toxins and pollutants from the air and rainwater. It absorbs carbon dioxide, toxic gases and dust from the air and produces oxygen. Filtering toxins from the rainwater prevents them from reaching the groundwater.
Reducing the phenomenon of urban heat pollution - a phenomenon known in crowded urban spaces characterized by multiple built-up areas. Built surfaces made up of dark and opaque materials such as asphalt and concrete are exposed to radiation during the day, absorbing the heat and affecting the rise in temperatures inside. In contrast, protective surfaces help lower the temperature in the city.
Holistic Value - In the constant competition for the city's areas, the green roof makes an intelligent use of an empty roof and turns it into an attractive garden in the heart of a built space. As a green area, it contributes to the sense of well-being of users and viewers. Reduces the electricity requirement for the merger by about 20% and saves costs associated with the execution and maintenance of urban drainage systems. The proof of the viability of the installation is reflected in an increase in the value of properties with a green roof.
