COMPARISON OF THE CALCULATIONS RESULTS OF HEAT EXCHANGE BETWEEN A SINGLE-FAMILY BUILDING AND THE GROUND OBTAINED WITH THE QUASI-STATIONARY AND 3-D TRANSIENT MODELS. PART 2: INTERMITTENT AND REDUCED HEATING MODE

Journal Title: Civil and Environmental Engineering Reports - Year 2017, Vol 1, Issue 24

Abstract

The paper provides comparative results of calculations of heat exchange between ground and typical residential buildings using simplified (quasi-stationary) and more accurate (transient, three-dimensional) methods. Such characteristics as building’s geometry, basement hollow and construction of ground touching assemblies were considered including intermittent and reduced heating mode. The calculations with simplified methods were conducted in accordance with currently valid norm: PN-EN ISO 13370:2008. Thermal performance of buildings. Heat transfer via the ground. Calculation methods. Comparative estimates concerning transient, 3-D, heat flow were performed with computer software WUFI®plus. The differences of heat exchange obtained using more exact and simplified methods have been specified as a result of the analysis.
