Ventilation of dwellings - decentralized - 6 x 120 m3/h (polyethylene ducts)

The activity generating the emissions is ventilation of dwellings, decentralized, 6 x 120 m3/h, polyethylene ducts. The Reference Product is ventilation of dwellings, decentralized, 6 x 120 m3/h. This is a immobile infrastructure, representing the product of a "ventilation of dwellings, decentralized, 6 x 120 m3/h". It is a typical decentralized ventilation system for a multi family house having 6 flats with 130 m2 floor area each and a ventilation rate of 120 m3/h. The system contains ducts made of steel or polyethylene and a earth tube heat exchanger. The lifetime of the system and ducts is 50 years, the lifetime of ventilation is 20 years and the lifetime of the filters is 1 year. The process includes materials inputs used for the construction and for the maintenance of the ventilation system, electricity consumption for the operation of the system and end-of-life. Influence of ventilation ducts on building construction not included. The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. Please refer to the ecoinvent documentation for full details: https://ecoquery.ecoinvent.org/3.12/cutoff/dataset/8819/documentation
