Vytau Virskus was born in a displaced persons (DP) camp in Southern Germany shortly after World War II. His parents were refugees from the Russian occupation of Lithuania in 1944. The family immigrated to the United States on a Liberty Ship and processed through Ellis Island. He grew up in Flint Michigan, and attended Michigan State University to study mathematics and mechanical engineering. Following graduation, he worked at MSU as an operations engineer and energy manager for a campus of 20M square feet. He left that position to pursue a degree in law at Thomas M. Cooley Law School (Western Michigan University) where he earned a Juris Doctor.

Vytau is the Principal of Millenium Energy Company (1998) (
and has over 35 years of power generation, energy management, and building automation experience. He has provided analytical, consulting, project management, and commissioning services for numerous commercial, institutional, educational, and industrial clients. Vytau has completed numerous successful energy efficiency and utility cost reduction projects for school districts, hospitals and universities, generating up to $1M in annual cost savings. Collectively, the total savings is estimated to be over $30M over the last 15 years alone.

Vytau has a diverse energy background, also having been involved in developing a number of electric generation projects, and has negotiated electric purchase power agreements with public utilities.

More recently he has developed a process for conversion of large-scale industrial, institutional, and commercial chilled and hot water systems to variable volume flow for which he received his first US patent. The mathematical algorithm makes it possible to convert large hydronic systems to variable flow, a major improvement in energy efficiency, which is otherwise very difficult without significant and costly physical piping modifications. His most recent patent is a new type of mass flow meter and thermal energy meter (MF/EM) designed for multiple types of fluids, including gasses.

His analytical focus is on energy analysis, solution development for implementation of energy retrofit projects, the design of enterprise-wide building automation and control systems, and energy commissioning to optimize energy savings.

Vytau has assisted companies in comparative analyses of energy use for national and global industrial operations to identify and prioritize energy system improvements based on energy intensity. He has provided consultation on enterprise energy utilization plans for multiple industrial facilities using up to $20M per facility, and has assisted in the development of loss reduction and system efficiency optimization strategies employing both current and emerging technologies.

Vytau is also an affiliate of a consulting group providing consultations on energy and building automation to national and international clients. He has also been a guest lecturer at the Michigan State University College of Engineering. Mr. Virskus serves on the Leadership counsel of Michigan Conservative Energy Form (MICEF). He is a member of the Association of Energy Engineers (AEE), a global organization, and has been a presenter at a number of AEE conferences on Energy Retrofits for Older Buildings. He is also a member of Energy Central’s Counsel of Experts (,

Mr. Virskus has received recognition and awards for his work from state, regional, and international organizations for energy retrofit projects for commercial, educational, municipal, and industrial facilities. The most recent energy and infrastructure replacement project for a major Michigan municipality, which included five buildings and .5 million square feet received a state award from the American Public Works Association (AWPA), a regional award from the international Association Of Energy Engineers (AEE), and was recognized by the Environmental Business International’s Climate Change Business Journal (CCBJ).

Mr. Virskus is a veteran of the United States Air Force, and is a lifetime member of the Veterans of Foreign Wars (VFW) having served in the Vietnam War.
