The Possibility Analysis of Adapting a Public Building to the Standard of a Building with a Zero Energy Balance

Abstract

The paper aims to examine the possibility of adapting an existing school building to the standard of a zero energy building. The school building is a specific case of a building in which the energy consumption is periodic, except for the months with the most sunshine. Therefore, it is necessary to look for a solution that will allow storing the energy obtained, for example, from solar collectors. Based on the analysis of the literature, it was concluded that the use of borehole thermal energy storage might be the right solution to the problem. The article presents the energy balance of the building with and without the use of renewable energy sources and the benefits of using an energy storage system.

Energy Effectiveness or Economic Profitability? A Case Study of Thermal Modernization of a School Building

“…Numerous examples of thermal modernizations of educational buildings in Poland have been presented recently [30][31][32][33][34][35][36][37][38], but economic evaluations were very simple and limited to SPBT or operation costs calculations. The energetic effect was in the foreground, but not linked to the investment cost and its projected lifetime.…”

Selected Aspects of Indoor Climate in a Passive Office Building with a Thermally Activated Building System: A Case Study from Poland

“…To achieve required level of energy performance low energy and passive buildings require appropriate heating sources and systems. Heat pumps with low temperature water-based embedded surface heating and cooling systems form efficient solutions [9][10][11][12][13][14][15].…”
