The state's building codes emphasize energy efficiency and protection against wind loads and hail. Foundation design must account for potential soil expansion due to moisture and the need to mitigate frost heave. The selection of durable exterior materials and effective air sealing techniques is critical for long-term performance and occupant comfort throughout the year.
