Levchenko Oleg Ivanovich

Oleg Ivanovich Levchenko was born on September 4, 1946, in Volochysk, Podolia, in what was then the Kamenets-Podolsky region. In 1950, his family moved to Proskuriv (now Khmelnytskyi), where he spent his childhood and school years.

He grew up in a large family, one of four children. From an early age, responsibility, independence, and respect for work were formed in him not as abstract values, but as a natural way of life. It was during these years that his interest in exact sciences and engineering thinking took shape: calm, systematic, and demanding toward details.
After school he entered the Kyiv Polytechnic Institute, choosing the Department of Micro-Radioelectronics. He studied with honors and graduated with a red diploma, as a person for whom the principle “done correctly” was not a slogan, but an inner standard.

Life Path

Oleg Ivanovich continued his professional career in the scientific field. In the late 1970s, he worked at the V. M. Glushkov Institute of Cybernetics of the Academy of Sciences of the Ukrainian SSR, where he was engaged in applied scientific and design work. His projects were related to state and industrial programs, and his developments were protected by numerous authors’ certificates and patents.

Over time, he headed a special design bureau, remaining not a purely administrative head, but an engineer: precise, demanding, and focused on real results.

After the collapse of the Soviet Union, he did not abandon science and engineering. On the contrary, his focus shifted toward practical solutions for real life: construction, thermal systems, and energy-saving technologies, where accurate calculation directly affects durability, comfort, and the quality of the environment.

He developed new materials, built technological processes, launched productions, and brought solutions to a state where they could be used for decades. For him, it was important not only to invent. It was important to make it work.

Engineering Legacy

The last years of his work became the logical outcome of everything he had gone through. Oleg Ivanovich sought to create materials and systems where engineering precision, ecological responsibility, and practical applicability coexist simultaneously, without compromises and temporary fixes.
He viewed building materials not as a commodity, but as an element of the environment that must be honest: predictable, durable, and transparent in its behavior. For him, durability was not merely a technical characteristic, but a form of responsibility toward people, resources, and time.

This is how the ECOS system appeared. Not as a single invention and not as a commercial product, but as a collected formula of his entire engineering life. Dry building mixes with minimal or zero Portland cement, concrete heat-accumulator technologies, ecological aggregates and new-generation crushed stone became the continuation of one principle: engineering should serve for decades, not for marketing cycles. ECOS did not become the result of one project, but the outcome of an engineering way of thinking shaped by years of precise calculations, practice, and responsibility for results.
