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

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. This is an immobile infrastructure representing the construction of a ventilation system decentralized 6 x 120 m3/h polyethylene 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. Air intake on the facade and direct to the 6 decentral ventilation units with a short galvanised steel tube (125 mm diameter). Distribution of fresh- and exhaust-air within the flat with polyethylene tubes (75 mm diameter). 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 cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
