主 题：mechanical ventilation demand control ventilation(DCV) indoor air quality(IAQ) CO_(2)concentration energy efficiency school buildings
摘 要：The advantages of the demand control ventilation system(DCV)have been widely discussed in previous research ***,the literature has not addressed the benefits of DCV on controlling indoor CO_(2)concentration and minimizing cooling energy consumption for school buildings located in extremely hot ***,this paper contributes to the development of DCV and mechanical ventilation systems through a comprehensive evaluation of these systems to maintain acceptable indoor air quality(IAQ)while minimizing cooling energy demands for school buildings located in the harsh hot climate of Saudi *** evaluation is based on a calibrated whole-building energy model and validated IAQ predictions using field data obtained from a school case study in *** results of this research study confirm that hourly and sub-hourly monitoring of indoor CO_(2)concentration is required to ensure optimal design and operation of the ventilation systems in *** addition,the analyses indicate that a 13%increase in cooling energy end-use can result for any additional 0.1 students/m^(2)density increase in the ***,the energy penalties related to ventilation needs can be reduced by up to 25%using DCV instead of conventional mechanical ventilation systems for school buildings located in Saudi Arabia’s hot climate.
