Hi everybody!
I am surprised what is it mean m2*a not unit for "market for ventilation of dwellings, decentralized, 6 x 120 m3/h" ?
Thanks for any help, Best, zahra
Dear Zahra,
the dataset “market for ventilation of dwellings, decentralized, 6 x 120 m3/h” describes a market for a ventilation system for a multifamily house. The house considered in the investigation includes 6 flats with 130 m2 floor area each and a ventilation rate of 120 m3/h. You can find this information in the respective transforming activities (e.g. ventilation of dwellings, decentralized, 6 x 120 m3/h, polyethylene ducts).
For more information, please have a look at the following report (German only), in which the data has been published:
Hässig W. and Primas A. (2007) Ökologische Aspekte der Komfortlüftungen im Wohnbereich. Final report ecoinvent data v2.0, No. 25. Swiss Centre for Life Cycle Inventories, Dübendorf, CH.
You can find this report under the report section when accessing version 2 of ecoQuery (report number 25).
