Charles Nii-Baah Amoo

Graduate Research Assistant



Charles Amoo is a graduate research assistant at the University of Tennessee, currently on subcontract at the Oak Ridge National Laboratory. He specializes in the assessment of energy efficiency and renewable energy technologies through energy modeling. Charles is also skilled in the creation of tools for conducting energy audits, focusing on building energy and water consumption, as well as health and safety considerations in residential structures, with a particular emphasis on low-income households.

In his role at Oak Ridge National Laboratory, Charles has made substantial contributions to various research initiatives, including the development of essential resources such as "Getting Started" documents and an Engineering Reference Manual for the Weatherization Assistant suite of audit tools, designed for existing residential homes and multifamily buildings. This suite encompasses critical components such as NEAT, MHEA, MulTEA, and Health and Safety Audit. Furthermore, he led research efforts in the evaluation of methodology for measure allowable lifetimes in the Weatherization Assistant Program (WAP).

Charles is an active member of several prestigious professional organizations, including ASHRAE, AEE, and PMI. He holds a Master of Energy degree from the University of Auckland in New Zealand, and is currently pursuing a Ph.D. in Energy Science and Engineering at the University of Tennessee, Knoxville.
