An end client requested a measurement that, to the best of my knowledge, does not seem technically feasible. I'm wondering if anyone has encountered a practical way to approach this.
A building has been constructed within an existing "artificial valley" surrounded by woodland and hills which raise above the building. Client wants to have a measurement on field of the lux level above the building and at level with the surrounding landscape. In such environment, even night light will contribute so the measurement should somehow isolate the contribution from artificial lighting only.
They say it's for environmental reason but sounds to me like an excuse to tell us we haven't accomplished the scope but perhaps I'm not updated.
Measurements around the building have already been provided, we just miss the measurements "above".
Do you have expertise in doing so or reference to standards / technical guides that would help me in challenging the request?
