Mixed-mode Ventilation and Air Conditioning as Alternative for Energy Savings: a Case Study in Beirut Current and Future Climate
• Assesses efficacy for the use of mixed-mode ventilation in a typical office building in a Mediterranean climate
• 31% annual energy savings were observed with mixed-mode ventilation
The aim of this work is to assess the use of mixed-mode ventilation for a typical office building in Lebanon and consequently reduce Heating Ventilation and Air Conditioning (HVAC) energy consumption in the observed current and under the future projected climatic conditions. Under present construction practices and weather data, 31% annual energy savings were achieved using mixed-mode system. Under future 2050s projected weather data, annual energy savings of 21% was attained with a payback period of 3.8 years.
