Hello, I'm trying to answer the V4 BD+C (New Construction and Major Renovation) daylight credit through option 1 (SDA+ASE). There is an option in Ecotect 2011 called Daylight Autonomy that allows the analyse for the entire year starting at 8 until 18h and with a required lighting level in default mode of 300 lux. Is this valid to fulfil the credit requisites? Seems made for it. This is the Ecotect report that I would send with the analysis grid (more than 75% SDA) Report: Grid Analysis Description: Percentage of nodes by contour band. Daylight Automomy (300 Lux) Contour Band Within Above (from-to) Pts (%) Pts (%) 75-80 19 0.49 3833 98.51 80-85 22 0.57 3814 98.02 85-90 52 1.34 3792 97.46 90-95 147 3.78 3740 96.12 95-100 3543 91.06 3593 92.34 About the ASE, a peak radiation calculation for the entire year from 8 to 18h with a scale from 0 to 1000 Wh (both the SDA and ASE with a 600mm square grid at a 76 mm height) generating an analysis over the grid and a report like the following is acceptable to fulfil the credit?
