h2x vs CAMEL+: The short answer

h2x and CAMEL+ both support detailed heating and cooling load calculations and psychrometric analysis, but they extend those calculations into different engineering workflows.

CAMEL+ is primarily focused on air conditioning loads, AHUs and plant analysis. h2x carries calculated loads directly into detailed HVAC and wider MEP system design, automatic duct and pipe sizing, pressure loss calculations and project outputs.

Project setup and load calculations
Floor plans and building geometry Upload PDF floor plans and draw rooms, walls, windows and other building elements directly over the project background before continuing into system design. Building data can be entered directly in CAMEL+. The optional Cnect 3D Builder allows users to import PDF floor plans, trace rooms and building geometry and export the model into CAMEL+.
Heating and cooling loads Room-by-room heat loss and heat gain calculations remain connected with the wider engineering design and system sizing workflow. Calculates chiller, AHU, zone and room cooling loads, boiler, zone and room heating loads, air quantities and associated air conditioning plant requirements.
Calculation methods and standards Supports regional and international methods and standards, including CIBSE methodologies, EnergyPlus Heat Balance workflows, ASHRAE 183-compliant peak load calculations, AS 1668.2 ventilation requirements and other system specific standards. Air conditioning load calculations are based on the AIRAH DA09 Air Conditioning Load Estimation methodology. CAMEL+ also supports AS 1668.2 Multiple Compartment Formula calculations for fresh air.
Psychrometric analysis Psychrometric calculations for heating and cooling coils are available through the Heat Balance Method and Psychrometric AHU sizing workflows. Psychrometric analysis is integrated into CAMEL+'s air conditioning load workflow, with calculations and a psychrometric chart provided for each AHU.
Weather and design conditions Uses the most recent ASHRAE 2025 climatic design conditions, with configurable project design conditions and ASHRAE design day workflows for heat gain calculations. Includes monthly design conditions for around 760 Australian locations, based on Bureau of Meteorology weather data spanning 2000–2021, together with locations across New Zealand and other regional markets.
Calculation checks and result review Results, warnings and heat maps help engineers inspect loads, system sizing, pressure losses, velocities and equipment duties as the design develops. Provides graphical input checks, project summary error indicators, load charts, check figures and detailed results for reviewing the load calculation model.
Connected system design
Connected load-to-HVAC design Calculated building loads feed directly into HVAC system design, where they are automatically used for system sizing and remain connected as the project changes. CAMEL+ calculates building and air conditioning plant loads. Detailed duct and hydronic distribution system design is provided through separate ACADS-BSG products rather than within CAMEL+ itself.
Ductwork design and sizing Engineers can draw ductwork directly on the project layout, with calculated loads feeding duct sizes, airflows, velocities, pressure losses and fan duty calculations. CAMEL+ provides the building and air conditioning load calculations. Duct network design and sizing is available separately through ACADS-BSG's DONKEY and DOLPHIN software.
Hydronic pipework design Engineers can draw hydronic pipework directly on the project layout, with calculated loads feeding pipe sizing, flow rates, velocities, pressure losses, index circuits and pump duties. CAMEL+ can calculate chiller and boiler loads, while detailed air conditioning water piping design is provided separately through ACADS-BSG's PYTHON software.
3D design review Built-in 3D View allows engineers to review building geometry alongside ducts, pipes, equipment and other MEP systems within the same connected project. The separately priced Cnect 3D Builder add-on creates building geometry from PDF floor plans with a live 3D preview, then feeds that geometry into CAMEL+ for load calculations. Its documented workflow focuses on building geometry and load-calculation setup rather than detailed 3D duct and pipe system design.
Project delivery
CAD and BIM interoperability Exports calculated system designs to AutoCAD and Revit for downstream drafting, coordination and BIM development. The separately priced Cnect for Revit add-on imports building geometry and room information from Revit into CAMEL+ to accelerate heat load model setup. Cnect 3D Builder is included with this add-on.
Project outputs PDF drawings, heat load reports, calculation reports, sizing reports, Bills of Materials, schedules, AutoCAD and Revit outputs. Provides load summaries, air quantities, load charts, check figures, psychrometric charts and printable or exportable results. Cnect 3D Builder can also produce HVAC zoning layout PDFs.
Collaboration and design review Secure read-only browser links allow colleagues, clients and checking engineers to review the latest design and connected calculations without an h2x licence. Cloud-based company workspaces support access to CAMEL+ projects by subscribed team members, while calculation results and project files can also be exported for review.

Project delivery and design review

h2x carries calculated systems into detailed drawings, reports, Bills of Materials and AutoCAD/Revit workflows, with browser-based project review. CAMEL+ produces load results, charts and reports, while optional Cnect tools support building geometry and Revit workflows.

Should you choose h2x or CAMEL+?

The better option depends on whether you want heating and cooling loads connected directly with detailed HVAC and wider MEP system design, or primarily work within an established CAMEL+ air conditioning load workflow.

Choose h2x Pick h2x if...

  • Building loads need to remain connected with detailed system design.
  • Calculated loads should automatically feed duct and pipe sizing.
  • Ventilation, hydronic, plumbing or fire systems also need to be designed.
  • Drawings, calculation reports, Bills of Materials and CAD/BIM outputs are important deliverables.
  • Browser-based read-only project sharing is useful for internal or external design reviews.

Choose CAMEL+ Pick CAMEL+ if...

  • AIRAH DA09-based air conditioning load calculations are central to your workflow.
  • AHU, zone, room, chiller and boiler load analysis forms a major part of your work.
  • Psychrometric analysis is a key part of your established HVAC calculation process.
  • CAMEL+ is already established within your company or project-review process.
  • Cnect 3D Builder or Cnect for Revit suits your building load model setup.

Verdict: h2x is the stronger fit for teams that want heating and cooling loads connected directly with detailed HVAC and wider MEP system design, automatic sizing and project outputs. CAMEL+ is the stronger fit where AIRAH DA09-based air conditioning load calculations and an established CAMEL+ workflow are the main requirements.

Why teams choose h2x over CAMEL+

Teams comparing CAMEL+ with h2x can keep load calculations, HVAC layouts, automatic system sizing and project outputs within the same connected project. This can reduce the need to transfer calculated loads into separate ductwork, pipework and documentation workflows.
