A designerly approach to Algae-based large open office curtain wall Façades to integrated visual comfort and daylight efficiency

Abstract

Providing daylighting and glare control in office buildings has always been one of the challenges for designers. This research investigates patterns for designing façades with optimal performance to provide daylight glare control, the possibility of natural ventilation, and control energy transfer from the façade. Accordingly, one of the proposed modeling methods is using glass in a part of the façade for optimal visibility and the possibility of natural ventilation. This study has simulated and analyzed three curtain wall categories: all-algae, all-glass, and combined glass and microalgae. Moreover, ordinary double-glazed and single-glazed windows are not used properly. Combined façades with 50% − 60% microalgae concentration, electrochromic LoE glass, and spectrally selective LoE tint glasses provide the most optimal patterns for designing curtain wall façades with microalgae of office buildings. Compared to the basic pattern (single glazed glass), the mentioned optimal patterns have reduced ASE by 28% and sDA by 50%.
