Until recently, renderings were the architect’s primary tool for understanding daylight in their designs—renderings, and a healthy dose of intuition. But a new generation of daylighting analysis tools, which is emerging alongside a new generation of daylighting metrics, are enabling architects to look at daylight in new ways—with important implications for design.
Business as usual, when it comes to daylight, is to use rules of thumb to design, then use renderings to check the design and communicate the intent. Rendering has fast become an art form: the creation of exquisite, evocative, often atmospheric imagery that communicates the mood, the experience, the visceral feel of the design. This is no accident: daylighting is a magic ingredient in architecture, bringing dynamism to static structure, imbuing buildings with a sense of time, and renderings are a powerful way to capture and communicate these ideas—a necessary complement to the hard line plans and sections that comprise much of the architect’s lexicon. Renderings have expanded our ability to communicate designs. They have also expanded our ability to conceptualize designs—and especially to conceptualize the daylight in our designs.
But there’s something missing: there are important daylight-related questions that renderings simply can’t answer. Even if they can be made reasonably accurate, they’re still incomplete: depicting a moment in time, but not providing an indication of whether that moment is unique or typical.
