Historical buildings are a major part of European and national cultural heritage which people all around the world decided should be preserved for the future. In order to conserve both the construction elements and the thermal comfort, it is crucial to find the optimal configuration of the energy related equipment. These units, besides fulfilling the parameters of thermal comfort, are also subject to the EU Ecodesign and energy labeling requirements and must meet a series of architectural restrictions. This article describes the research conducted on environmental, technical and legal methods, used to ensure efficient thermal comfort, in the case of an historical building from Bucharest?s Old Town.

If the final purpose of the site is a restaurant or a pub, the problem of ensuring the minimal standard room conditions of temperature, humidity and fresh air becomes more complicated. After evaluating a series of cooling, heating and fan configurations in order to increase the energy efficiency, we introduced into the main designed system a heat recovery unit. The work is based on the numerical modeling of the thermodynamic processes and energy balances applied for each analyzed configuration.

Due to the location of the building in the city center and in a protected area of national heritage, it becomes impossible to introduce renewable energy sources. Upon analyzing the results of the numerical modeling, we removed the solutions that did not meet the specific technical limitations and have recommended technically acceptable values having the highest economic efficiency. The final optimal system we designed for the analyzed case consists of a central air handling unit (AHU), fan coils, chillers and the related components.

The economic analyses made for the investment, was focused on the added recovery unit and its payback period.
