Analysis of the Method of Heating and Cooling of an Office Building

The aim of this paper was the analysis of the heating and cooling of a two-story office building located in northeastern Poland, which leads to making practical conclusions. The main part of the work focuses on determining the projected heat loss as well as heat profits of the building under scrutiny, in which the information serves as initial data for the selection of devices of the systems under analysis. For the analysis, we assess the installation of fan coils—underfloor—which heat or cool a room and the installation of radiators for heat, and the multi-split air conditioner for cooling. For every variant, we estimated the investment costs and the operating costs. The comparison enabled to present conclusions and advice concerning the heating and cooling of small office buildings. In the summary, the reader will be able to familiarize with conclusions concerning the price and comfort of the implementation of solutions.
