Climate intelligence
for the built environment.
A platform for AEC teams to turn climate datasets into decisions. Organize work in projects, explore maps and layers on a WebGPU-accelerated canvas, and connect 3D context when needed.
_ Open /playground — explore the canvasFrom datasets to decisions
Havn combines a project workspace, a WebGPU canvas, and climate intelligence pipelines so AEC teams can analyze, communicate, and act on environmental risk.
