Dynamic Simulation of the Energy Performance of the Timber-Frame Passive House
摘要整理
The aim of this article is analysis of energy performance of the timber-frame passive house. The analysis is made on the base of numerical simulation, analytical calculation and experimental measurement. Numerical simulation is solved by the Design Builder software which can determine thermal losses, thermal loads of buildings and other parameters of indoor microclimate - mean radiant temperature, operating temperature and indoor relative humidity, the Predicted Mean Vote (PMV) index, the Predicted Percentage Dissatisfied (PPD) index, concentration CO 2 (carbon dioxide). Analytical calculations are solved by the software Simulace. Boundary conditions of the exterior calculation are set with using standard values and the real hour meteorological values (from database of the software Design Builder for Ostrava town and from database of the real experimental measurement values). Experimental measurements of the indoor and exterior parameters (external and indoor air temperature) are realized at the passive timber-frame house of the Research and Innovation Centre of the Moravian-Silesian Wood Cluster in the area of the Faculty of Civil Engineering, VSB – Technical University of Ostrava. Results of theoretical analysis and experimental measurements are compared and evaluated.
