Introduction

Rockcastle, Siobhan; Andersen, Marilyne

Pages: 1 –8

[Most architects would agree that daylight is an important asset to the design of good architecture, but what aspects of natural light quantify or qualify the visual performance of a space? Perceptual qualities such as contrast and temporal variability are essential to our appreciation of...

Research Context

Rockcastle, Siobhan; Andersen, Marilyne

Pages: 9 –22

[Through a comparison of existing interior spaces, this chapter will introduce a range of daylight design strategies found in global contemporary architecture. Each strategy varies in its approach to sunlight penetration and daylight distribution, yet reinforces a specific spatial experience that...

Architectural Context

Rockcastle, Siobhan; Andersen, Marilyne

Pages: 23 –35

[The previous chapter began with a critical look at existing daylight performance metrics and strategies for evaluating brightness and contrast within architectural space. We then presented the need for more visually dynamic and spatially dependent methods for quantifying contrast and temporal...

Defining New Metrics for Contrast and Variability

Rockcastle, Siobhan; Andersen, Marilyne

Pages: 37 –51

[In the previous chapter, we conducted a survey of contemporary global architecture to develop a typological language about the range of contrast-driven effects in daylight design. Each example was placed within a larger matrix to establish a gradient from high contrast on the left to low...

Application of New Metrics to Abstract Spatial Models

Rockcastle, Siobhan; Andersen, Marilyne

Pages: 53 –68

[In this Chapter, we will apply each metric introduced in Chap. 4 to a series of rendered case study spaces to test their success in quantifying and comparing spatial contrast, annual spatial contrast, and annual luminance variability. Although a total of fifteen categories were established in...

Application of New Metrics to Detailed Case Studies

Rockcastle, Siobhan; Andersen, Marilyne

Pages: 69 –80

[In the previous chapter, we applied spatial contrast, annual spatial contrast, and annual luminance variability metrics to a series of rendered case study spaces. The results for each metric were compared to show how they differentiate between dynamic qualities of contrast and luminous diversity...

Conclusion

Rockcastle, Siobhan; Andersen, Marilyne

Pages: 81 –83

[This book began with a critical look at existing daylight performance metrics through the lens of contemporary architecture. It established the need for new performance criteria that could account for the range of perceptual and temporal qualities within designed space and position those...
