Hi, this may be a silly question, but I do not know if there is any special requirement o detail that force me to start a project following CS v4 instead CS 2009. Is CS 2009 obsolete? I know it is recommended to start as soon as possible with CS v4, but is there a critical reason for it? We have a client that thought in CS 2009 and we do not know if, when CS v4 is already working, if it is possible to start the registration with CS2009. Thank you in advance and sunny regards.

Toni, you can choose to use either Version 2009 or Version 4 until October 2016. Project registered after October 2016 MUST be Version 4, but for now you can choose either. There are arguments in favour of both versions, it mainly depends on the intentions and commitment of the owner.

Emmanuel, are there arguments for v2009 besides easier/less expensive?

Joel, I don´t think so. V4 makes a lot more sense to me and it puts LEED where it should be, challenging teams to make a project more efficient and sustainable. We are currently doing projects and without doing anything special we usually end up with LEED Silver. It all depends on the countries of couse, but in general in Europe and the US I would say that is the case.
