In fact, Levitt defines the single greatest technological limitation for daylight simulation as computer processor speed with complex scenes taking more than 12 hours to render. And as previously noted, there is a significant lack of expertise within the design community when it comes to daylight modeling.

In the grand scheme of things, Dalgish sees the learning curve and workflow integration as being daylight modeling’s biggest limitations. “Although the software compatibility has improved, there is still a gap in cleaning up or simplifying the architectural geometry to create a reasonable calculation time,” she says.

The effectiveness of an integrated shading/ dimmer design working in concert, especially in office environments, can impact the bottom line. Window shades can be automated to provide maximum efficiency while helping you lower your overall power bill.

“Daylighting software can be exceptionally accurate, but the software alone cannot guide specifiers,” explains Levitt. “The expert must decide how to model a particular building, what elements of a daylight system to prioritize, how to visualize results and how to interpret those results.”

Wausau’s INvision Thermal Unitized system leverages a polyamide thermal barrier to enhance system thermal performance, condensation resistance and energy efficiency.

First Net Zero Public Safety Building

Fiberglass Phenomenon

As the first net-zero public safety building in the U.S., Salt Lake City’s new 335,000sq.-ft. facility features Wausau Window and Wall Systems’ unitized curtainwall, light shelves and sun shades.

An attractive option for exterior solar shading, Fibergrate is a fiberglass reinforced plastic composite grating that is lightweight and durable. As pictured here at an Arizona State University dormitory in downtown Phoenix, the orange square mesh molded grating creates shaded pods for student gathering areas.
