I could be wrong but it does not look like a Sempervivum. It looks like Echeveria Chroma. The plant looks like it is not getting enough light.
The care and growth of Sempervivum and tender Succulents are different.
Can I suggest you post it on the Cactus and Succulent Forum and ask if anyone can positively ID it with more knowledge than me.
