Ropiak, Mariusz and Brotas, Luisa (2012) Ventilation for comfort and efficiency in theatre. In: 2nd Masters Conference: People and Buildings, 18 September 2012, London Metropolitan University, Graduate Centre. London, UK.
This paper focuses on two subjects: comfort levels and efficient ventilation in Arcola theatre in London, which strives to become the first zero carbon theatre. Being a leader in promoting sustainability in arts, Arcola is looking for a sustainable solution for its performance space.
Air quality and thermal comfort were examined. To investigate air quality measurements of carbon dioxide levels were undertaken in the studio space during performances. To assess thermal comfort temperature monitoring was carried out for three seasons. The results showed that air quality in the studios does not meet the requirements. The air infiltration rate is not adequate for its high occupancy load. Insufficient ventilation in the space results in elevated levels of carbon dioxide. Temperature monitoring revealed that generally the space can provide comfortable conditions for most of the year. However, there were problems during hot days and during winter time. In hot whether the temperature in the studio rises to uncomfortable levels and it is not possible to effectively reduce it by ventilation. During winter, temperatures were quite low due to lack of space heating. Summarising a ventilation system is necessary to provide optimal comfort levels in the theatre. The strategies proposed have been based on the monitoring data as well as other research into natural ventilation in a theatre.
