"Our room doesn’t actually have any airflow in it, so our highly sophisticated air con system is basically opening the door for five minutes. As it’s a shell inside a larger building, there’s also no heating, and the winter was bitterly cold. Luckily, the room is small and insulated, so it’s fairly easy to heat using a small electric heater." I suggest reading up a bit on air circulation strategies for studios before doing something similar. They're not that hard to do and it beats suffocating.
