His major strengths are the development of creative energy solutions utilizing his extensive knowledge of controls and control theory, more than 35 years of experience in energy management and conservation, and his practical, empirically-oriented approach to project solution development.

Millenium utilizes the most current technologies to integrate legacy control systems, with the newest open protocol energy management and control system, and to integrate facility HVAC controls to respond automatically to industrial process requirements. Mr. Virskus concentrates on creative energy project solution development, building automation and energy management system design, and on-site generation projects. Clients include municipal and state governments, schools, industrial and commercial facilities, as well as national and multinational clients.

Mr. Virskus has designed numerous energy projects including computerized energy management systems, HVAC retrofits, internet accessed metering systems, controls large-scale variable flow chilled water cooling and heating systems, and on-site generation installations. Millenium Energy Company uses the most cutting-edge technology available to design sustainable systems that meet LEED certification and Energy Star designation standards. Mr. Virskus focuses on integrating strategic energy planning with creative application of the most current energy technology in order to provide the highest energy efficiency at the lowest cost to clients.

Professional Background

Prior to forming Millenium Energy Company Mr. Virskus worked in various positions, serving as a Regional Manager for the state of Michigan, responsible for the start-up of all energy services operations in the state, including the establishment of an office in Southeast Michigan, creating a client base, developing analytical tools, and implementing utility cost reduction projects. He has also served as Vice President of Business Development and Regulatory Affairs for an energy/environmental and metal fabrication company serving the auto industry. He was responsible for developing numerous projects, including the use of catalytic reduction of paint fumes.

As a founding member of Resource Energy Company, Inc., Mr. Virskus assumed the position of Vice President of Operations. His responsibilities included the development of power generation projects of up to 100 megawatts. He negotiated agreements with five municipalities in Wayne County and was responsible for contract negotiations with Detroit Edison, Florida Power, Baltimore Gas and Electric, and Bechtel Corporation. He was responsible for projects having development budgets of up to $2 million and having a total project cost of up to $85 million.

As an energy management consultant for public schools, Mr. Virskus has provided technical analyses for energy management projects through Michigan School Business Officials (MSBO), a nonprofit organization providing technical services to the state's public schools. He conducted over 800 energy audits of school buildings and was also on contract with the Michigan Energy Administration to perform energy audits for state facilities. Mr. Virskus conducted numerous seminars and classes on pneumatic and electric controls and building automation systems.

In 1975, Mr. Virskus began his career in engineering as an Environmental Systems Manager and Operations Engineer for Michigan State University. He was responsible for a staff of 35 heating, ventilating, and air conditioning maintenance personnel and building operators serving campus buildings totaling over 3 million square feet.  His early responsibilities included the installation and development of the campus-wide energy management system ultimately serving 80 major buildings on the campus. His accomplishments include formulating and implementing a plan that achieved a 10% energy cost reduction during the course of one year; design and implementation of energy management systems in a number of new campus buildings; developing a new concept for balancing and optimizing central chiller plant operations with variable volume pumping techniques; creating the campus-wide steam and electric metering system; initiating the use of infrared thermal imaging for identifying building energy losses; and developing a process to convert large constant volume chilled water pumping systems to variable volume using differential energy control techniques.

Mr. Virskus has over 15 years of experience in the legislative and regulatory process, monitoring changes in the EPAct, Clean Air Act, Clean Water Act, RCRA, OSHA, and other federal and state environmental statutes and regulations. He developed a procedure for in-depth comparative analysis for regulatory programs in all 50 states. He also led a team to develop a strategy for implementing an air emissions inventory under the Clean Air Act for large clients in the auto industry utilizing the federal CAA database.

He participated in the drafting and passage of several bills relating to power and environmental issues. He served on the Michigan Underground Storage Tank Financial Assistance (MUSTFA) fund advisory panel in 1994-1995, working with legislative and administration staff to draft $800 million in underground storage tank legislation. His experience includes air, water, and other environmental permitting with federal and state agencies, as well as with county and municipal governments. He has also participated in drafting and negotiating contracts for the sale of electric power by private generators to public utilities under PURPA, including a power purchase agreement for $13.5 million for 35 years.

In 2016, Mr. Virskus was awarded a U.S. patent for dynamic differential energy control of hydronic heating or cooling systems. Known commercially as E~flow, this patented mathematical algorithm uses building energy demand rather than pressure as the primary control variable to slow down or speed up a hydronic pump through a variable speed control thereby increasing or decreasing volume flow.

He has also made numerous presentations to commissions, boards, and councils across the state, from county to local levels, presented testimony on energy and environmental issues before Senate and House committees at the state legislature, and negotiated contracts with major private companies and public organizations.
