We are writing to clarify the role of dedicated theater spaces in Credit EQ 8, Daylighting & Views calculations. Dedicated theaters (as opposed to multi-purpose rooms) are used solely for theatrical performance and rehearsal. The intent of a theater is to exclude all natural light and views so that lighting and audience attention can be focused on the stage. Other spaces in this project (adjacent office spaces, workshops, etc.) will be daylit per the intent of the credit. Is it acceptable to remove the dedicated theater spaces from the daylight and views calculation?
Occupants in a theater, including activities such as seating, cleaning and stage work, will benefit from daylight, however, a 2% daylight factor and access to views may be inappropriate. Dedicated theater space can qualify as a daylit space in credit calculations if the daylight design meets the recommended illuminance of 10 footcandles as noted in the IESNA Lighting Handbook Reference & Application. To document compliance, submit a daylight simulation model or daylight measurement of the theater space. Dedicated theater space may be excluded from EQc8.2 calculations for access to views. If daylighting is not provided, the space can be excluded from the credit calculations along with a narrative describing theatre activities and how daylighting will hinder these activities. Applicable Internationally.
