ACCA Certified Manual J and Manual S
Manual J 8 System Sizing Calculations
The SizePro versions allow you to calculate ACCA Manual J eighth edition for sizing heating and cooling systems. This can be calculated as room-by-room, zones or whole house.

Manual S System Selection Summary
Manual S allows the selection and sizing of heating and cooling equipment to meet loads for a home based on local climate and home construction specifics.

ANSI / RESNET / ACCA 310 HVAC Design Report
The SizePro versions include producing an ANSI / RESNET / ACCA 310 HVAC Design Report that provides the design intent of the system which can later be compared against the installed system.

ACCA Certified Manual D Reports
The SizePro versions allow you to calculate duct sizes according to ACCA Manual D, specifying each of your elbows and other connectors. The software works for all systems except panned (not ducted) airways and zoned damper controlled systems.
Kwik Model 3D drawing tool
Versions that include Kwik Model 3D allow you to create all of the geometry entries by drawing the house. Starting with a scanned floor plan, walls, roof, floor and windows can readily be entered for use in EnergyGauge calculations. Kwik Model 3D can also be used for drawing the duct design for mechanical drawings.
Model Photovoltaic System Performance
EnergyGauge allows entry of up to three unique on-site solar power generation systems. For example, you can enter details for systems on the east, south, and west sides of your house. Select from a database of photovoltaic modules and inverters or enter your own specifications.
Generate Hourly Reports for Utilities
Detailed, hourly simulation modeling and reporting using an FSEC-enhanced version of the widely respected DOE-2.1E building energy simulation program. Includes the ability to drill down to any month, day, or hour, as needed for your analysis.
Florida Energy Code
