Since our firm’s founding, designing for and with daylight has been a central aspect to our workflow. While tools have advanced considerably, our focus on designing incredible spaces in collaboration with architects continues.  Today, we use the most up-to-date tools to shape the daylighting in your spaces. We work best as part of an integrated team; using a variety of methods we can easily integrate our daylighting analysis with formal investigations throughout the design process, taking advantage of opportunities latent in parametric software, and advanced rendering platforms.



  • Façade analysis and design
  • Daylight modification and shading design
  • Glazing specification including electrochromics
  • Automatic shading design and controls specification
  • Glare analysis
  • Daylighting and electric lighting integration
  • LEED and CHPS daylighting calculations
  • Pre and post-occupancy analysis



We have years of experience developing and using daylighting analysis tools to understand and improve daylighting performance in buildings. Our designers rely heavily on open-source engines like Radiance and Daysim integrated into DIVA for Rhino and Honeybee/Ladybug, with a strong emphasis on parametric design in Grasshopper. We also use 3ds Max and iRay for visualization, seen in the sliders in the case studies.


Physical models are a timeless and an intuitive design tool. Since daylight is scalar, we can test physical models for daylight quality, and easily test design variations. We perform physical model analyses on one of two in-house heliodons.


We are also experts in ‘in real life’ analysis including pre-/post-occupancy on-site analysis, HDR photography to analyze daylighting conditions of as-built spaces, and lighting level measurements.
