EN 17037 Method 2 with UK national annex parameters — dynamic climate-based assessment for projects in the UK requiring above-minimum compliance.
The UK national annex to EN 17037 Method 2 applies UK-specific thresholds to the climate-based dynamic assessment. It requires median illuminance analysis for 50% and 95% of space coverage, following BRE documentation.
DL-Light runs the full dynamic calculation with UK parameters and produces the complete synthesis report, ready for submission to planning authorities in the UK.
UK Method 2 synthesis report
EN 17037 Method 2 for the UK is the British annex to the European standard, incorporating specific requirements for UK daylight assessment. It uses climate-based dynamic simulation with UK weather data and additional criteria for daylight adequacy.
DL-Light applies the UK annex of EN 17037 Method 2, using UK-specific weather files and thresholds. It computes dynamic illuminance at working planes and assesses compliance against UK-modified criteria for the three performance levels.
The UK annex modifies EN 17037 thresholds for climate-specific conditions. It requires assessment of both target illuminance and daylight distribution, with specific criteria for different room types and building classifications per the UK standard.
