Ayse Gizem Tas
Architect · Sustainability Consultant · Permaculture Designer · Systems ThinkerI’m Gizem. A decade of sustainability consulting taught me one thing: the problem is rarely just technical.
My work spans green building certification (LEED, BREEAM, WELL, Fitwel), Life Cycle Assessment, embodied carbon analysis, energy and daylight modeling across 40+ projects in Europe and the Middle East, from airports to data centers to flagship retail. The technical depth is real, it matters, and I bring hands-on rigor to every stage of delivery. Because buildings that perform well on paper should also support the health and wellbeing of the people inside them.
But what I’ve come to believe: the most critical sustainability decisions fail not because of missing data, but because of missing translation. Numbers that don’t connect to decisions. Certifications that don’t change behavior. Reports that get filed and then quietly forgotten.
So the work goes further into climate facilitation, systems-thinking workshops, regenerative education, and my role as a founding member of the Ecology and Architecture Commission at the Istanbul Chamber of Architects. As a certified Climate Fresk facilitator, active member of the Terra.do Learning for Action Tapirs Cohort and a sibling of Regenerators community, my focus shifts to how people understand buildings and their impacts. Because that shift matters as much as optimizing how buildings perform.
That's the gap this practice works in.
