Some succulents get stressed not just by cold, depends on whatever factor is causing the stress. Could be heat stress, dehydration stress, cold stress, just depends what stress factor is prevalent in the season it is growing in.
Anyways, going back to the original poster's question about his/her jades, my observations stands, plant needs some adjustment in light. And as Tiffany mentioned too, jades are slow growing plants. At times, after the increase in height it will try to redirect resources to fattening up its leaves and trunk, but with not enough moisture to drink it is not going to do it as well. Jades are succulents not cacti that goes dormant in winter indoors.
On the good side, RueOshaRose, the color of the leaves is solid green, but that is good, leaves are alive. I would be more concerned if the leaves starts going yellow, dropping and no new growth or if the trunk starts going mushy soft. So there is lots of potential growing there for your plant. Good luck! Hope plant adjusts and recovers.
