Abstract: Buildings have become a key issue in developing of sustainable solutions due to their significant contribution to total CO2 emissions and substantial energy consumption. Special attention is devoted to building ventilation, which has a significant rate of building energy consumption. HVAC systems are essential for maintaining a healthy environment for building occupants. Natural ventilation uses natural forces such as wind and temperature differences to fresh air circulation. Mechanical venti- lation systems are designed to provide continuous circulation of fresh air in buildings, thereby im- proving indoor air quality. Modernly designed mechanical ventilation systems utilize advanced tech- nologies such as heat recovery units, which reduce energy consumption and improve building energy efficiency. This paper presents modeling of different ventilation strategies in a residential building, using EnergyPlus software. Simulations were provided for selected summer and winter days. Ob- tained results for natural ventilation showed zone ventilation heat losses and gains, while mechanical ventilation system with heat recovery is modeled with emphasis on indoor air quality.
