KEY PRINCIPLES OF SOLAR PHOTOVOLTAICS INTEGRATION IN THE BUILDINGS OF ARCHITECTURAL HERITAGE

The problem of photovoltaics integration into the building of architectural heritage is in
the zone of compromise between aspects of preservation and long-term use. The quality and
success of such energy modernization are based on the principles of preserving and extending
the term of the utilitarian use of buildings. It is crucial in this situation to determine the key
principles of solar cell integration into buildings that form the historic environment. The
constituent values of historic buildings form the basis for their definition. Domestic researchers
have previously focused on some issues of "inconsistency" in the domestic monument
protection legislation, which occur not only without formal violations of the law but on the
contrary, based on its rules. The article continues the research of problems, methods, rules,
and limitations of photovoltaic systems integration into the architecture of historical buildings
initiated by the authors. The purpose of this article is to consider issues related to the cultural
value preservation of the historic buildings in the integration of solar systems, as well as to
determine the priorities, value characteristics defined by legislative and regulatory documents
of Ukraine, value components of the historic buildings. The purpose is also to measure the
value components` interaction and to form the principles of solar cell integration based on it.
The basic priority in making decisions on energy modernization, switching to new energy types,
and introducing solar generation, is to promote the preservation and long-term operation of
cultural heritage buildings. In total, the components form a broader definition of the value of
historic buildings and environment, which goes beyond what is defined by law. Decisions on
energy measures for cultural heritage buildings require a search for a balance of priorities
between different value components. Based on the value components, nine principles of solar
cells integration into historic buildings have been formed.
