Jimeno Fonseca is an expert in urban energy systems, digital urban planning, and sustainable city design. With a PhD from ETH Zürich and over 2,000 academic citations, he is known for co-developing the City Energy Analyst (CEA) and contributing to the field of Positive Energy Districts (PEDs). His work bridges research, practice, and open-source technology to support cities in their energy transitions.

The City Energy Analyst (CEA) is an open-source urban energy planning tool developed to model and optimize energy use at the district and city scale. Jimeno Fonseca co-founded this project during his research at ETH Zürich to help urban planners and engineers make data-driven decisions for sustainable city design.

You can access and implement Jimeno Fonseca’s tools, including the CEA, through open-source repositories and detailed documentation. They are designed to be replicable, transparent, and adaptable, helping cities and developers simulate building energy demand, district energy systems, and carbon emissions scenarios.

Positive Energy Districts (PEDs) are urban areas that produce more renewable energy than they consume. Jimeno Fonseca has led multiple projects and research initiatives on PEDs, focusing on modeling, design strategies, and real-world implementation in European cities.
