HVAKR is organized into sections that follow the natural HVAC design workflow.

Project Structure

Each project contains the following sections, accessible from the left sidebar:

Basis of Design

Configure project-wide settings that affect calculations:

• General - Project information and metadata
• Weather - Design conditions and weather station
• Building Data - Envelope properties (walls, windows, roof, slab)
• Space Types - Occupancy, equipment, and lighting loads
• System Types - HVAC system configurations
• Sheet Library - Floor plan uploads and management

Building Model

Define the physical building:

• Sheets & Maps - View and navigate floor plans
• Spaces - Draw and configure spaces
• Envelope - Assign walls, windows, and other envelope elements
• Zones - Group spaces into thermal zones
• Systems - Create and configure HVAC systems

System Design

Design the HVAC systems:

• Configuration - Central and terminal unit settings
• Air Balancing - Airflow distribution and balancing
• Layout - Duct routing and sizing
• Selections - Equipment selection from catalogs

Reports

View and export calculations:

• Loads - Cooling and heating load results
• Energy (Beta) - Energy use and analysis
• Estimation (Beta) - Cost estimation
• Files - Generated PDF reports and exports

Below these sections, the sidebar footer links to the 3D Viewer, Present mode, and Settings.

Toolbar

The top toolbar runs across the top of every project view:

• Project name - click to rename the project inline
• Save status - shows when your work is saved; HVAKR saves automatically, so there is no manual save button
• Undo / Redo - appear once you’ve made changes
• Collaborators - avatars of everyone currently in the project
• AI (Beta) - open the HVAKR AI assistant
• Chat - open project chat and comments
• Share - open the sharing panel
