Thermal comfort of individual rooms in the design of commercial buildings

This paper presents the results of the annual numerical simulations in the design of commercial buildings. The calculations were carried out in the Energy Plus, tightly integrated within the Design Builder program, which provides the simulations of both building envelope and building interiors. The simulations conducted for the Polish climatic conditions allowed the evaluation of the thermal comfort of the entire building and of the particular rooms. Influence of different solutions, insulation, shadings and occupancy density on the internal thermal conditions were analysed in this paper.
