Why might energy calculations be required for Home Owner Builder permits?

• A. Energy calculations are sometimes required to demonstrate compliance with energy efficiency requirements in the climate zone; if required by code.
• B. They are never required.
• C. They are only optional for large homes.
• D. They are used to design landscaping.

Answer: (A)

Energy calculations are used to show that a home will meet the local energy efficiency rules for the climate zone. When a permit is reviewed, the building department may require these calculations (or an approved rating) to prove the design complies with the energy code targets for insulation, windows, air sealing, and heating/cooling efficiency. This helps ensure the house will perform well and not waste energy. They aren’t about landscaping, and they aren’t universally required for every project—only when the code asks for evidence of energy efficiency.
