Do you already have a license or whatever is legally required? I don't know if you have an equivalent to P.E. in the US, though. I first would try to acquire ALL legal licenses that are even remotely related to your work before spending time and money on unnecessary (legally speaking) certs.
A long list of certs looks great and might get you an interview, but in the end your boss comes with a new project and asks who can legally design and stamp it, and that is where licenses rule.
I'd ask potential clients and investigate first if it really has meaning to THEM. I work for an owner, and I bet 100% of people who are on the selection committee don't know what it is. And if they do, they would wonder if it is legally required or not. Hell, I had to google it when I saw your post. We often see people who DON'T have an actual license come up with those lesser certificates to make up for a lack of license (since a license is harder to obtain).
IMHO, those are money grabbing schemes. We have the PE license. But in theory I also could get a CEM (certified energy manager?), this ASHRAE thing and so on. I also bet that someone who passes PE, could pass any of the other tests. So you don't literally learn new things while studying. What they all have in common is that anyone who has the money can sit for the test.
