Ventilation system - decentralized - 6 x 120 m3/h - steel ducts (ventilation system production)

The activity generating the emissions is ventilation system production, decentralized, 6 x 120 m3/h, steel ducts. The reference product is ventilation system, decentralized, 6 x 120 m3/h, steel ducts. This is an immobile infrastructure, representing the construction of a ventilation system, decentralized, 6 x 120 m3/h, steel ducts that is used in a multi family house. The house considered in the investigation includes 6 flats with 130 m2 floor area each and a ventilation rate of 120 m3/h. The infrastructure represents a decentralised ventilation system without ground heat exchanger, including 6 decentral ventilation units with a short galvanised steel tube (125 mm diameter). Distribution of fresh- and exhaust-air within the flat with galvanised steel ducts (100x50 mm). Exhaust air from the 6 decentral ventilation units with a short galvanised steel tube (400 mm diameter) direct to the exhaust on the facade. The lifetime is assumed to be 50 years. The process includes building materials and their decommission. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity. Please refer to the ecoinvent documentation here for full details: https://ecoquery.ecoinvent.org/3.11/cutoff/dataset/11238/documentation.
