The Building Emissions Reduction Standard (BERS) is Ontoly's certification framework for quantifying, verifying, and issuing carbon credits from building retrofits. It sets the rules for how emissions reductions are measured, what qualifies, and how credits are tracked from issuance to retirement — all on a public registry.

Ontoly works with several types of suppliers who create BERUs from real building retrofit projects.
Building Owners & Managers
Monetize your retrofit savings as certified carbon credits.
Retrofit Consultants
Offer clients a carbon revenue pathway alongside your advisory services.
Retrofit Engineering Firms
Connect your engineering work directly to verified carbon outcomes.
Several types of buyers purchase BERUs — each with different goals but the same need for high-integrity, building-level carbon credits.
Voluntary Carbon Market Buyers
High-integrity credits backed by real utility data, not estimates.
Green Building Certification Buyers
Offsets for Zero Carbon Standard, LEEDv5, and similar programs.
Building Performance Standard Compliance
BERUs may qualify as a compliance mechanism under emerging Building Performance Standards — channeling finance to real retrofit projects. Subject to jurisdictional approval.
