As we ring in 2022, the Passive House Accelerator magazine once again brings encouraging stories of project teams, policymakers, and manufacturers delivering climate-friendly building solutions. Passive House techniques—in concert with building electrification, clean energy, and low embodied carbon materials—chart a clear pathway toward climate action for the building sector.

We hope the practical guidance found in these pages will inspire imitations galore. And, while we are always excited to document the increasing adoption of Passive House approaches, in this issue we are particularly thrilled to have an article by José Sosa Rueda covering the growth of Passive House in Latin America.
