ElumTools Computes PPFD for Horticulture

ElumTools supports a separate and specific mode for horticultural lighting calculations. When the software is set in Horticulture Mode, luminaires can be assigned output in terms of PPF (Photosynthetic Photon Flux in µmol/s, typically provided by the luminaire manufacturer), or by PPF Factor (µmol/s/kilolumen) which can be computed from the spectral power distribution of the light source. All point-by-point calculations will then be expressed in terms of PPFD (Photosynthetic Photon Flux Density, µmol/(s^.m²)). Rendered results are shown in pseudocolor (below).

ElumTools Layout Assistant will also compute the luminaire quantity required to meet a specific PPFD average in the selected calculation zone (Room, Space, Region, etc.) for growing applications of any size and shape.

You can then calculate the PPFD at the individual points, or simply accept the estimate and automatically populate the area with the new luminaire locations in Revit. It does not get any easier to accurately predict lighting results.
