Looks like a useful data base. I see they provide free access for a year:
"The board of CERA Databank decided to admit the public free access to the databank index and calculation modules. However, only the full paying users will receive full access to the databank formulas. The non-paying users will therefore not be granted access to the most valuable information in the databank, but will hopefully be able to extract enough information to solve simple CAPEX problems. Our hope is that this gesture will boost the interest in CERA Databank and attract more paying users. It’s as simple as that! The free access period will initially last for a duration of 12 months."
