Upward Flux Ratio (UFR) Calculation

Post by iliase » Thu Feb 06, 2020 2:59 pm

Hello everyone,

The new ILP Guidance Note (01/20) for the reduction of obtrusive light (2020) introduces additional Sky Glow limitations. The new limitations relate to the Upward Flux Ratio (UFR) values and are identified in Table 7 of the document in question.

Is there an intention for a new version of Dialux 4 to be released that would automatically calculate the UFR value (in the same manner that it does for ULR)?

Hello Ilias,

Our strategy for the future is that DIALux evo is the successor of DIALux 4.13 and that we will only develop DIALux evo in the future. However, we will continue to support our DIALux 4.13 software.
Nevertheless, no new features will be implemented in our DIALux 4.13 software.

However, we will forward this issue to our product owner. They will discuss this topic intensively and include your request in our improvement list for future evo versions.

Best regards,
DIAL Support Team
