This study simulated the performance of various mechanical supply and exhaust ventilation systems, incorporating heat recovery, in a typical Finnish residential apartment building. Dynamic thermal simulations were undertaken, representing a period of a year. These simulations incorporated the building details combined with information about the HVAC-systems, internal thermal loads and outdoor climate.
This paper reports the results of computer simulations of a hybrid-ventilated building using ESP-r (Environmental Systems Performance for research). A new school building in Norway was used for this simulation study. The research attempted to verify the use of this model for the simulation of a real building utilising hybrid ventilation technologies. The simulations and their analysis focus on the buildings thermal and ventilation performance.
The demand for buildings with high quality indoor environments is growing, especially in developing countries, where more and more energy will be consumed in the near future. Air flow pattern, air temperature and humidity are among the main parameters that contribute to indoor thermal comfort. Care must be taken to design the most energy-efficient air distribution system that provides comfort for the occupants. To achieve this it is very helpful to know the air flow patterns and the temperature and humidity field in a building at the design stage.
Creating a computer model that is able to simulate different ventilation scenarios within a structure is essential for improving the understanding of passive designs that are both sustainable and environmentally acceptable. The purpose of this investigation was to build a prototype model that could be heated from both the outside and inside to duplicate an occupied structure during the morning hours. Two Computational Fluid Dynamic (CFD) models were created for this study to firstly compare and then validate results obtained from experimental data.
