Light Is the Architect's Most Important Material

Louis Kahn called natural light the giver of all presences. Every architect understands that light defines space—it establishes mood, reveals form, and connects occupants to the world outside. But controlling light in practice is a constant negotiation between competing demands: maximizing daylight for occupant wellbeing, minimizing glare for visual comfort, managing solar heat gain for energy performance, and maintaining exterior views.

Window treatments are where many of these competing demands get resolved. The right treatment enhances the architect's daylighting strategy. The wrong one undermines it.

Beyond Light or Dark

Traditional window treatments offer a binary choice: shade up (full light) or shade down (reduced light). This doesn't reflect how buildings actually perform throughout the day. A south-facing conference room might need full blackout during a presentation at 2 PM but benefit from diffused daylight during a morning brainstorming session. An east-facing patient room needs protection from direct morning sun but open views in the afternoon.

Custom printed shades can be specified with different fabrics for different facades, different floors, or even different rooms on the same floor—each calibrated to the specific solar conditions of that orientation and use case.

Solar Heat Gain and Energy Performance

For architects pursuing aggressive energy targets, solar heat gain management is critical. Our light-filtering fabrics have solar heat gain coefficients (SHGC) ranging from 0.15 to 0.35, depending on the material and color of the print. Darker prints absorb more solar energy, while lighter prints reflect more—a factor that should be considered during the design phase.

We can provide SHGC values for specific fabric/print combinations to support your energy modeling. For LEED projects, this data feeds directly into the EAc1 Optimize Energy Performance calculations.

Glare Control Without View Obstruction

Glare is the most common complaint in daylit buildings. The instinct is to close the blinds, which solves the glare problem but eliminates the daylight and view benefits the architect worked to achieve.

Our light-filtering fabrics reduce glare while maintaining a visual connection to the exterior. Occupants can still see sky, landscape, and horizon—the view is softened, not eliminated. The printed imagery on the shade adds an additional design layer that's visible when the shade is down, creating a secondary visual experience.

Integrating with Automated Systems

For buildings with automated shade control, we work with all major motorization platforms: Lutron, Somfy, Crestron, and others. The motorized shades can be programmed to respond to solar sensors, time-of-day schedules, or occupancy, ensuring optimal light conditions without manual intervention.

The printed imagery remains effective at any shade position. Whether the shade is fully deployed, partially raised, or at any intermediate position, the design reads as intentional.

Case Study: A Law Firm's Corner Office

A recent project illustrates how these principles work together. An architecture firm designed a corner partner's office with floor-to-ceiling glass on two exposures—west and south. The views were spectacular: San Francisco skyline and bay. But afternoon sun created debilitating glare on the partner's monitor and heated the room well beyond comfort.

We installed light-filtering shades with a subtle cityscape print that complemented the actual view. The fabric reduces solar heat gain by 70% while maintaining visual transparency. The partner can see the skyline through the shade—the real view and the printed interpretation layer over each other in a way that's visually compelling rather than obstructive.

The result: a space that performs all day, in all seasons, without the partner ever needing to choose between comfort and view.

Early Engagement Matters

The most successful shade integrations happen when we're engaged during Design Development. This allows us to coordinate with the facade consultant on solar performance, with the electrical engineer on motorization power and controls, and with the architect on ceiling pocket or fascia details that affect shade installation.

If you're designing a building where daylight control matters—and it should matter in every building—we'd welcome the conversation.

Frequently Asked Questions

How do custom printed shades support architectural daylighting strategies?

Custom printed shades manage daylight by controlling solar heat gain, glare, and light distribution while maintaining the architect's design intent. Unlike generic shades that simply block or filter light, printed shades become part of the daylighting design—using fabric opacity, print density, and color to shape how natural light interacts with interior spaces.

Can printed shades help achieve LEED daylighting credits?

Yes. When properly specified, custom printed shades contribute to LEED IEQ Credit 8.1 (Daylight) by managing glare while preserving required illuminance levels. Our light-filtering fabrics allow calibrated amounts of daylight to pass through while printed designs reduce contrast ratios at the window plane. We provide photometric data to support LEED submissions.

What openness factors are available for daylighting applications?

OrangePiel offers printable fabrics with openness factors ranging from 1% (nearly opaque) to 10% (moderate view-through). For daylighting applications, 3-5% openness is most common—it provides effective glare control while admitting enough light to reduce artificial lighting needs during daylight hours.

How does the printed design affect light transmission through the shade?

Darker, denser areas of a printed design transmit less light than lighter areas. This creates a natural variation in light transmission across the shade surface, which can be used intentionally—for example, placing denser print areas opposite direct sun exposure while allowing more light through in areas facing ambient sky.
