daglichttoetreding berekenen
Calculating daglichttoetreding: a practical NEN 2057 workflow
Proving compliance means showing that Ae is equal to or greater than the required equivalent daylight area set out in the Bbl, using the NEN 2057 method: Ae = Ad_effectief × Cu × Cb. Every window contributes an effective daylight area, corrected for glazing transmittance and any obstruction outside. That number gets
