Sefaira has launched a major upgrade to Sefaira Architecture, cloud-based software that enables project teams to design high-performance buildings by helping them understand their energy use, environmental impact and occupant experience. Sefaira Architecture now shares a technology platform with Sefaira Systems, facilitating better collaboration between architects and engineers in the early design stages. The upgrade also better facilitates passive design, particularly for residential buildings, schools and offices. It incorporates new thermal comfort capabilities and reports, new natural ventilation capabilities including free area calculations, and new downloadable charts. Architectural designers can now analyze their buildings not only holistically but also on a per-zone or per-room basis.
