Current climate-based daylighting metrics are optimized for evaluating office and classroom spaces and have limited applicability for residential use cases; they fail to highlight relevant aspects of natural light in residential spaces, such as diurnal and seasonal availability of daylight and access to direct sunlight. The Residential Daylight Evaluation Framework (RDEF) is introduced as a new climate-based, annual methodology to quantify daylight autonomy and access to direct light in temperate and cold climates; diurnal and seasonal bins are introduced to specifically highlight when undersupply occurs.
Scores based on these assessments can be produced to objectively compare the daylighting performance of different apartment units. Several methods of visualization are tested: Spatial maps representing daylight autonomy and access to direct light can be overlaid on plans of apartment units and floors, while false-color volumes representing final scores can be used for the building- and urban-level. A consideration for the early-design application, when specific partitions within units are not yet finalized, is given in the form of re-adjusting scores and/or altering metric threshold values.
