NEW YORK, LONDON – 17 SEPTEMBER 2015 – Sefaira, the leader in software for high-performance building design, today announced that it expanded its best-in-class daylighting analysis to include Direct Sunlight Analysis, including a 1-click solution for SEPP 65 direct sunlight requirements. This analysis is available to Sefaira customers immediately and complements Sefaira’s existing daylighting and real-time energy analysis capabilities.

Direct sunlight analysis allows building designers to understand where and for how many hours a space receives direct sunlight. This analysis is required for code compliance in different parts of the world, including Australia’s SEPP 65 requirement, the UK’s BRE Site Layout Planning for Daylight and Sunlight, and the B3 code in Minnesota in the US. Apart from code compliance, direct sunlight analysis is used by many building designers for passive solar and shading device design.

Australian customers see huge time saving potential from Sefaira’s new analysis capability 

SEPP 65, an environmental planning policy addressing apartment design in Australia, requires good daylight in residential living spaces (measured as a minimum number of hours of direct sunlight). With Sefaira, architects can now generate a full compliance report on SEPP 65 sunlight requirements in one click from their Trimble SketchUp or Autodesk Revit model.

Matthew Blair, Principal at BVN, one of Australia’s largest architectural practices, says that clients want to know early on if a particular project will meet SEPP 65 requirements.

“Being able to rapidly visualise and accurately quantify the actual solar access to living, working and public spaces during the design process is a very powerful tool to help improve the amenity and liveability of our cities,” he explained. “By using Sefaira, we can speed up the design/test/design process – we can understand solar access from the very start of design and rapidly iterate to create fabulous apartments and fantastic places for people.”

Mads Jensen, CEO of Sefaira, said: “We are in constant dialogue with our customers around the world. We’ve found that architects are under increasing pressure to meet code requirements, particularly around daylighting. Working towards a goal like compliance with SEPP 65 or meeting other sunlight levels can help designers more successfully implement performance-based design.”

Sefaira had launched daylighting analysis in 2014 and enhanced daylighting visualization earlier this year. Analysis capabilities include annual daylighting and time-of-day simulations. Using this powerful suite of tools, architects are able to intentionally design and communicate the quality of light in their buildings.
