The screenshot displays the 'System Design' feature of the h2x software, specifically for configuring a radiant floor heating system. At the top, there is a breadcrumb navigation with a 'Back to Project' button on the left and a 'Add New System' button on the right. The main section includes fields for 'System Name', 'Floor System', and 'Pipe Material', with dropdown menus for selecting options. Below, there are input fields for 'Max. loop length', 'Available Roll Lengths for Generic Coils', 'Min. bend radius', 'Max. loop spacing', 'Transit Spacing', 'Loop Direction Degrees', and 'Return Temperature', each with units specified. The 'Loop Shape' and 'Spiral Chirality' have dropdown menus for selection. At the bottom, there are color-coded buttons for 'Loop Colors' with an option to add more colors. The left sidebar contains navigation links under 'General', 'Calculations', and 'Other' categories, including 'Workflows', 'Info', 'Import', 'Methods', 'Systems', 'Heat Load', 'Nodes', 'Units', 'PDF Exports', 'Line Types', 'Hot Keys', 'Catalog', 'Marketplace', 'Budget', and 'Debug'.

The screenshot displays six diagrams illustrating different configurations of room and attic spaces in a building, relevant to heat load design. Each diagram shows a combination of 'Room' and 'Attic Room' or 'Empty Loft Space', with labels indicating 'Room Height', 'Roof Height', and 'Floor 2 Room Height'. The configurations include: 'No Vaulted Ceiling or Roof Needed' with 1 Level, 'Vaulted Ceiling Needed' with 2 Levels, and 'Vaulted Ceiling Needed' with 3 Levels. The diagrams also specify conditions such as 'Set 2nd Floor to Room Height 0'. These visual representations help in understanding the spatial requirements for heat load calculations in building design.

Skylight (Velux/Roof) Window

The screenshot displays a simple 3D illustration of a building with a flat roof, which is part of the 'Draw Building' feature under the 'Heat Load Design' section in the h2x software. The building is depicted with two large windows and a door on the visible side, emphasizing the flat roof design. This visual is likely used to assist users in understanding or selecting roof types for heat load calculations within the software.
