-Extensive simulations were used to assist the building owner and manufacturers in making informed decisions on the design and control of an automated roller shade and electric lighting control system for The New York Times Headquarters in the pre- and post-bid phases of the project. ​ A prior monitored field study in a full-scale mockup answered initial questions concerning technical feasibility and performance benefits of automated control. Simulations enabled extension of the monitored field study to the final building in its complex urban context.+Mardaljevic carried out all of the climate-based daylight modelling for this landmark evaluation. ​Extensive simulations were used to assist the building owner and manufacturers in making informed decisions on the design and control of an automated roller shade and electric lighting control system for The New York Times Headquarters in the pre- and post-bid phases of the project. ​ A prior monitored field study in a full-scale mockup answered initial questions concerning technical feasibility and performance benefits of automated control.

 Radiance simulations were used for a variety of purposes, from understanding the effects of urban shadow on shade useage to assisting with pre-calibration of photosensor sensitivity in a complex daylit interior environment. ​ Time-lapsed images enabled stakeholders (building owner and manufacturers) to visualize the daylit environment of the final building in its urban context with automated shade control and assess how well visual comfort (direct sun, surface luminance), daylight quality (illuminance level and distribution),​ and view were to be addressed by the system at different orientations and locations within the building. ​ Inherently, a top-down roller shade compromises daylight when lowered to control direct sun and glare. ​ Simulations were also used to determine whether minor adjustments to the shade control algorithm could increase interior daylight levels without compromising visual comfort. ​ All of the above simulations were made for a discrete set of days, typically solstice and equinox days using CIE clear and overcast sky conditions and was sufficient for the directed purpose.  ​ Radiance simulations were used for a variety of purposes, from understanding the effects of urban shadow on shade useage to assisting with pre-calibration of photosensor sensitivity in a complex daylit interior environment. ​ Time-lapsed images enabled stakeholders (building owner and manufacturers) to visualize the daylit environment of the final building in its urban context with automated shade control and assess how well visual comfort (direct sun, surface luminance), daylight quality (illuminance level and distribution),​ and view were to be addressed by the system at different orientations and locations within the building. ​ Inherently, a top-down roller shade compromises daylight when lowered to control direct sun and glare. ​ Simulations were also used to determine whether minor adjustments to the shade control algorithm could increase interior daylight levels without compromising visual comfort. ​ All of the above simulations were made for a discrete set of days, typically solstice and equinox days using CIE clear and overcast sky conditions and was sufficient for the directed purpose.  ​
