The Theatres Trust have asked for those in smaller venues to get in contact with information regarding their ventilation systems. There are four key questions:

• Does your theatre have a mechanical ventilation system installed? (ie as opposed to comfort cooling or heating that conditions and recirculates air
• Which spaces within your venue have a ventilation system (eg main auditorium, studio space, bar, dressing rooms etc).
• Does the ventilation system allow for increased levels of fresh air intake?
• Is there a building management system (BMS) controlling the ventilation equipment?

If you are happy to answer, there are a couple more BMS related questions below:

• If yes, does the BMS use CO2 levels from sensors in the venue?
• If yes, what values does the BMS use?
• Is there a maximum value which the system tries to keep below?
