Abstract [en]
This paper investigates novel computational methods for Regenerative Design by developing further on the European Daylight Standard EN 17037, to make it useful at both urban and architectural scales. Case studies are evaluated for sunlight, daylight and quality views. A computational method, compliant with EN 17037, is introduced for the evaluation of sunlight. An assessment of daylight metrics, for an office building in Helsinki, with a 300 lux target, demonstrates a 12% difference between spatial Daylight Autonomy (sDA; occupied hours) and Illuminance levels (EN 17037 method 2; daylight hours), 37% between sDA and Daylight Factor (EN 17037 method 1), and 25% between methods 1 and 2. A new computational method for evaluating ‘views’ on the floorplan is proposed that considers ‘view content’ (EN 17037 View Out layers), ‘view access’, the potential viewpoint-based ‘outside distance’, and can be extended to add the ‘quality of environmental information’. Further research directions and use of spatial metrics are discussed for sunlight, daylight, and view quality.
