Abstract

Systems, computer readable media, and program product/code for providing enhanced energy efficiency and reduced greenhouse gases for an eco-industrial park with retrofit in mind and eco-industrial park retrofit with retrofit in mind, are provided. An exemplary system includes a computer configured to perform the operations of identifying hybrid inter-time zones inter-area matching solutions through selecting best energy efficient routes, generating technically viable energy efficient eco-industrial parks alternatives, identifying best generation and allocation of energy utilities, and synthesizing a combined heat and power utility system that satisfies the eco-park demands during each time zone as well as rendering its best operating scenario at each specific time-zone. This inter-time-zones inter-area integration can include identifying the best and the second best matching solutions among processes in the eco-industrial park for spatial energy integration and the best and second best matching solutions among all time-zones for temporal energy integration and greenhouse gas emissions reduction for the optimal synthesis or retrofit of eco-industrial parks.
