Real performance data, simplified for real decisions.

Carbon & Energy Impact Reports

Each home design below is matched to your climate zone to maximize comfort, reduce energy consumption and ensure your builder can easily adapt the plans to local code requirements.You will not find this information anywhere else — it’s the same performance data we use with major partners and Government programs.


Why Understanding Your Climate Zone Matters

Knowing your climate zone is one of the smartest steps you can take before building or upgrading your home. Each zone across the U.S. experiences different temperatures, humidity levels, and seasonal shifts — all of which have a direct impact on comfort, energy use, and long-term performance.


Whether you're planning a new build, renovating, or simply wanting to improve your home’s efficiency, knowing your climate zone helps ensure you're making decisions that truly suit the place you live. It's a simple insight that leads to smarter, more sustainable living.

Every Green Home performs differently depending on where you live. Our Carbon & Energy Impact Reports provide a data-driven snapshot of how your home will perform in your state, showing exactly how much energy you can save and how much carbon you’ll cut by building or upgrading the Green Homes way.

Each report is based on verified modelling and years of field data from actual homes. It compares your home’s projected energy use and utility costs against a standard build, helping you see real-world value, not just claims.
