What should be measured and accounted for when conducting area takeoffs for a building?

When conducting area takeoffs for a building, it is crucial to measure and account for components like soffits and roof areas, as these elements contribute significantly to the building's overall airtightness and energy performance. Accurate area takeoffs help in understanding the total surface area that requires evaluation for air leakage, which is vital for building performance assessments and achieving tighter building envelopes.

Considering all relevant components, including soffits and roof areas, ensures that all surfaces are accounted for in the airtightness testing process. This comprehensive approach supports the goal of identifying potential air leakage sites, ultimately helping to improve the building's energy efficiency. Failing to include these areas could lead to an underestimation of the total area, resulting in insufficient measures to address airtightness.
