Stick it outside. Sempervivums do really well outside and are incredibly cold hardy.
If your pot has no drainage hole, and regular soil, and you want too keep your plant at home, you need to repot in the cacti succulent soil and the pot with the bottom drainage hole asap to prevent death to your plant.
I would put it outside as well, but you could potentially keep it inside on the windowsill but I would do as @SvelteKingfern said and make sure you have a drainage hole
