Using long-term measurements of airflow, electrical power, indoor temperature, and CO 2 -concentration for evaluating sizing and performance of an all-air HVAC system in an office building - a case study

Abstract: Monitoring performance of heating, ventilation and air-conditioning (HVAC) during building operation enables to evaluate the appropriateness of the system's design. Such insights can help to reduce energy consumption while ensuring satisfying indoor conditions in the monitored building. Additionally, such insight can help to improve future HVAC design. The aim of this paper is to present a case study demonstrating how HVAC engineers can evaluate whether the monitored air-handling units (AHUs) were appropria… Show more
