Ruchi Choudhary is a Reader in Architectural Engineering in the Department of Engineering, University of Cambridge, United Kingdom.

She specializes in building simulation and environmental characteristics of the built environment.

At Cambridge, she is leading the multi-disciplinary Energy Efficient Cities initiative (EECi) with colleagues in transport technologies and urban planning. Her current research concerns urban-scale energy simulation of built environments, with specific emphasis on uncertainty analysis and retrofits of existing buildings. The work investigates how simulation science can support pathways towards energy efficient cities, taking into account large variability among buildings, and a highly dynamic context associated with economics, regulations, and the influence of new emerging technologies.

The research has led to new methods and tools for the simulation community: a simulation platform for multi-period energy retrofits under economic uncertainties; stochastic urban-scale energy model that quantifies the impact of current UK policies; and spatial energy network optimization tool. These tools predict energy and emissions due to buildings at requisite time and spatial resolution.

Ruchi Choudhary received her PhD in Architecture from the University of Michigan in 2004.

Prior to joining Cambridge in 2008, she was Assistant Professor of Building Technologies, College of Architecture, Georgia Institute of Technology, Atlanta, USA (2004-08). She has also taught in the Sustainable & Environmental Design Unit at the Architecture Association, London (2007-09).

Her research has been published in journals including: Applied Energy, Energy and Buildings, Journal of Building Performance Simulation, and Sustainable Cities and Society.

Ruchi Choudhary was a workshop presenter at the 6th International LafargeHolcim Forum for Sustainable Construction in Cairo, April 4-6, 2019.
