I am a Brightway2 beginner. A result has complicated my life for a few weeks now and I can't find any solutions. I've dealt with it by various tricks but I would still like to understand this problem: when I search in my database for an activity with the name "glazing" for example, I get activities like "phenol", "polysulfide production"... Even if I look at the description of these activities, I don't understand (and this complicates my life a little). (db = ecoinvent 3.6) Any ideas? Maybe this is not the right place for this kind of question... Thank you in advance. Jean
code:
activity_name = 'glazing'
myProducts = []
for activity in Database("ecoinvent 3.6 APOS").search(activity_name, filter={"location" : 'RER'}):
myProducts.append(activity)
myProducts
out:
['glazing production, triple, U<0.5 W/m2K' (square meter, RER, None),
'glazing production, double, U<1.1 W/m2K' (square meter, RER, None),
'glazing production, double, U<1.1 W/m2K, laminated safety glass' (square meter, RER, None),
'polysulfide production, sealing compound' (kilogram, RER, None),
'phenol production' (kilogram, RER, None),
'phenol production' (kilogram, RER, None),
'methacrylic acid production' (kilogram, RER, None)]
Search is working as intended: You are looking for the term glazing, and it shows up in all the given results. For example the comment to polysulfide production has the sentence:
This dataset is primarily used in the glazing production.
If you only want activities with glazing in the title:
only_glazing = [ds for ds in Database("something") if 'glazing' in ds['name']]
You could also test against ds['name'].lower() to get case independence.
In general, searching with list comprehensions is going to produce more sensible results than .search, which is more for data exploration.
