“…And heating, cooling, and mechanical ventilation for residential and service buildings represent more than 20% of this energy consumption, where infiltration and ventilation is one of the main contributors to that 20%, although that percentage varies with climatic, building, and HVAC context (Santos & Leal, 2012). With decentralized ventilation, the mechanically allocated air flows are directly transported through the façade rather than by a single centralized large air handling unit (AHU) by transportation through a net of ductwork, so that concerning for the stricter energy demands, decentralized ventilation units offer lower SFP values than a centralized ventilation (CV) system (Altendorf et al, 2022;Baldini et al, 2014;Cui et al, 2017;Kim, 2022;Kim et al, 2014;Speer et al, 2014). Baldini and Meggers (Baldini, 2008) presented that the DV system, which has fan power of 55 Pa, and fan efficiency of 20% could reduce around 76 % fan energy demand compared with the CV system, which has 800 Pa of pressure drop and 70% of fan efficiency.…”
