We’ve introduced support for **parapets** in our wind loading calculations, helping you better align with ASCE 7 provisions and real-world roof conditions.

**🔧 What’s new**  
You can now toggle **“Include Parapets?”** to activate parapet-specific inputs and outputs. When enabled, the calculator:

- Takes a **parapet height (h\_parapet)** input

- Adjusts wind pressure calculations to the **top of the parapet**

- Applies code-based parapet provisions automatically

**📍 Where it applies**

- **MWFRS (Directional & Envelope):** Always available

- **C&C:** Available only for full-building / zone-based calculations (not effective area)

**🌬 MWFRS parapet pressures**  
Includes a dedicated table with:

- Windward: **+1.5 (GCₚₙ)**

- Leeward: **−1.0 (GCₚₙ)**

- Pressures calculated at parapet height using updated **Kz and velocity pressure**

**🧱 C&C support**  
For applicable cases, parapet pressures are computed using:

- **ASCE 7 Eq. 30.6-1 and zone logic**

- Windward → positive wall zones (4–5)

- Leeward → negative zones depending on load case

This update makes it easier to model parapets accurately without manual adjustments, keeping your designs consistent with code and saving time.
