Methods of researching the state of historical buildings energy efficiency

While rebuilding post-war Ukraine, there will be a need to introduce historical buildings into the discourse of energy-efficient improvements both to ensure the energy security of the country and to preserve the historical fund and increase its potential in the context of prospects. The process of energy-efficient reintegration of a historical building requires the use of complex methods for collecting information about the current state of the building, which include both historical and social history collection, as well as non-invasive measurements of the building's characteristics, as well as object modeling for analytical studies of the building's indicators. These studies are conducted to establish the energy-economic characteristics of the building in order to identify the potential for reducing energy consumption and minimizing the impact of the building on the environment. Methods of researching the current state of historical buildings energy efficiency are determined by two principled approaches, which involve either direct measurement of building characteristics, or simulation of an analytical model to calculate indicators, based on parametric data and characteristics of the building environment. However, they are preceded by the collection of the building`s historical anamnesis, to understand the context, essence and processes that historically took place in the building and affect the current energy consumption. A careful analysis and a balanced understanding of the historical building is required to set goals for the ongoing renovation of the historical building for the further selection of innovative solutions and energy-efficient strategies.
