Hello everyone, We are working on a project attempting option 2: Perimeter measurements. 

How should exterior lighting in terraces from retail should be addressed? specifically in this case we are talking about a coffee shop terrace, whose customers will be performing activities such as reading and working. The lighting power density complies with mandatory requirements of ASHRAE 90.1-2010, section 9.4.3, and the average illumination levels (3 footcandles) meets IESNA Lighting Handbook recommendation.

The exterior lights will be on from 6:30-8:30 am and then again from 6:00-10:00 pm. Then, lights go completely off.

The thing here is that this zone is intermediately to the project boundary, is there an addenda addressing this scenario or, is there a chance this area could be excluded from measurement points?
