ABSTRACT

There is a significant number of historical buildings with different destinations in Romania and all of these are yet dealing with major problems in terms of energy efficiency. The legal status of these buildings involves various restrictions concerning solutions that might be applied in order to ensure its’ energy efficiency. Therefore, applying the classic solutions to maintain the thermal comfort within patrimony buildings becomes very hard to accomplish or even impossible in some cases.
The purpose of the study case presented in this paper is to determine the optimal solution for thermal comfort assurance, from the energy and architectural design impact point of view, for the analyzed building. The building is declared historical monument and is currently under renovation and restoration.
For this purpose, we considered analysis of several solutions for thermal energy supply, that will not affect the inside design, that would be able to integrate within available space and ensure an effective energy efficiency (minimal loss and consumption for a certain demanded thermal performance).
The room allocated to our study has approximately 100 m2 and a medium high of 10 m. For this type of room, with a very high height, air thermal stratification issue must be taken into consideration, as temperature differences up to 18 oC might be reached vertically.
The main analyzed heating methods were: convection and radiation heating, floor heating and warm air heating. Hall’s construction characteristics exclude the option of mounting air ducts to enable the distribution of the warm air where heating is necessary. Heating using warm water heaters involve the existence of a dedicated room for the boiler and its afferent equipment, as well as qualified personnel to work with those, meaning increased operational costs.
In addition, being in accordance with the European trend of using decentralized sources of renewable energy becomes very difficult, as long as following this trend may lead to protected sites’ deterioration. Therefore, it is a must to adapt classic technology to legal restrictions.
