Urban & Regional Development along with Infrastructure Development:
Main aspects of Urban & Regional Development :Provision for most appropriate and convenient systems in terms of both service as well as quality to support economical growth of theboth service as well as quality, to support economical growth of the city, betterment of lifestyle and diverse needs and functions of the city.Not just defining these goals but also continuously evolving them to suit the changing times and changing needs of the people. Continuous improvisation of the tools and techniques of implementation not just for current situation but also for the new needs of the futures of the society and the city. The needs of the society and the tools & techniques to achieve them should so blendsociety and the tools & techniques to achieve them should so blend that urban development and infrastructure development to be in unison and harmony.
Urban & Regional Development along with Infrastructure Development:
Main Aspects of Urban Infrastructure Developments :Not just support the existing needs of the city but also revitalize it for further developmentfor further development.Support and facilitate up-gradation of social infrastructure like educational facilities, medical facilities, recreational facilities etc.Accountability towards growth of the city, balance between the demand and supply ratio and efficiency & effectively of City Governance.
Aspects of Urban Regional Development along with Infrastructure Development :`Compact` : Controlling scattered & unregulated urban sprawl development and developing urban areas in form of walk-able communities with human scale as the key criteria.
`Smart` : Maintaining the balance between demand and supply and consistently carrying out effective and efficient city governance.
`Localization` Appropriate technology and customized implementation strategy to meet and suit the local ground conditions.

Concept of Urban-Regional Development & Infrastructural Up-gradation
Axiom 1 ‘Compact’ controlling urban sprawl & emphasizing human scale development.
Close Knit (Consolidated) City Structure:Condensing major city functions into a small number of functional hubs to increase the efficiency of the citysmall number of functional hubs to increase the efficiency of the city. Low Carbon City Structure:An energy-efficient city with a close workplace-residence consolidated lifestyle and low dependence on private vehicles.Environment Friendly City Structure:A planned, eco-friendly approach to maintenance of natural resources, eco-fragile areas and green spaces.

Consolidated, Environmentally-Friendly Urban Hub Model:
Condensing major city functions into a small number of hubs would lead to a high-density development with efficient land use, thus enabling the maintenance of open space in a more planned mannermaintenance of open space in a more planned manner.
Improved workplace and residence relation, to upgrade and improve lifestyle (ease, comfort & safety).
Mixed-use & diversity of usage to allow exchange of surplus energy between residential area and industrial area, aiming towards mutual benefit and energy efficiency.
Close-Knit (Consolidated) City Structure + close workplace-residence C ose t (Co so dated) C ty St uctu e c ose o p ace es de ceconsolidated lifestyle reduces dependency on private cars and in the process makes an energy-efficient city.
Concept of Urban-Regional Development & Infrastructure Upgrading
Axiom 2 ‘Smart’ Maintaining Demand & Supply balance along with effective & efficient city governance.
Packaging: Not isolated bundles of individual technologies, but an integrated package of various technologies developed togetherpackage of various technologies developed together. Mutual Coordination : Not just appropriateness of individual utilities, but a mutual harmony between various utilities.Continuing Development : In accordance with the growth of city, continuance of development within an appropriate framework and at suitable scales.

Infrastructure Model to Suit ‘Local Production for Local Consumption’:
Devise an efficient management system to minimize internal energy loss asDevise an efficient management system to minimize internal energy loss as well as dependence on external energy sources.
Establishing an appropriate infrastructure system by using a realistic architecture module of CEMS’s Smart Community.
A module that is flexible enough to facilitate the incremental changes of the city as it develops step by step.
Shifting from a comfortable but energy-hungry model to an energy-efficient as well as economical and environment-friendly model.

Axiom3 ‘Localization’ Appropriate technology and customized implementation strategy to meet and suit the local ground conditions.
Reflecting facts views & values of local area: Understanding properly theReflecting facts, views & values of local area: Understanding properly the local issues and making a proposal to suit the over all environment.
Practical & Realistic Approach: A carefully considered choice between the latest and most appropriate technology to suit the local needs.
Customized System for Local Use: Customization of the system to suit the economic criteria as well as to enable its local operation and management.
