Graphical Representation of Climate-Based Daylight Performance to Support Architectural Design

Modelling ‘non-visual’ effects of daylighting in a residential environment

“…How can this temporal information be best represented? For a single point sensor, a temporal map can be used to give an overall visual picture of a year, based on annual weather files [52] and plotting days of the year along the x-axis and time of day along the y-axis: in Figure 5 for example, two view positions close to the window are compared using the same colour scale (0-1000lux), but one is associated to a view directed slightly rightwards from the window (6a) and the other pointing frankly to the right (i.e. view direction parallel to the window, Figure 5b).…”

Daylighting Design in Classroom Based on Yearly-Graphic Analysis

“…In other words, DA can show that for 70 percent of annual working hours, a particular point has adequate daylight, but it cannot show whether this point is underperforming in the morning hours, or in the winter [33]. The team of Andercen developed synthesis analysis tools, Lightsolve, to overcome this issue [32][33][34]. Lightsolve does annual daylghting calculation with the ASRC-CIE sky model and displays yearly data on a temporal map that a color-scaled surface graph with the year on the x-axis and the day on the y-axis.…”

“…The regular temporal maps display all of the annual data on one surface picture [33]. In the author's opinion, the designer should pay more attention to the daylighting performance in occupancy time, which would make the optimization more efficient.…”

“…In 2013, the energy consumed by buildings, artificial lighting of existing time-based metrics, like DA (Daylight Autonomy) [23,24] and UDI (Useful Daylight Illuminance) [25] that do reflect the proportion of annual work hours that achieve an illuminance benchmark or acceptable range while do not account for which times or areas that illuminance does not meet the recording threshold. In other words, DA can show that for 70 percent of annual working hours, a particular point has adequate daylight, but it cannot show whether this point is underperforming in the morning hours, or in the winter [33]. The team of Andercen developed synthesis analysis tools, Lightsolve, to overcome this issue [32][33][34].…”

Exploratory analysis of time-lapse imagery with fast subset PCA

“…In this paper, they use their "Spatio-Temporal Irradiation Map" to model sunlight variations in architectural design. The authors of [10] also use similar maps to model solar intensity for lighting design.…”
