HVAC Design Software

In the 2026 engineering landscape, HVAC Design Software has shifted from siloed drafting tools toward integrated ecosystems that combine 3D modeling, thermodynamic simulation, and statutory compliance. Under the Energy Efficiency and Conservation Act (EECA) 2024, software choice is now dictated by its ability to provide auditable data for Building Energy Intensity (BEI) and Specific Fan Power (SFP).

At EKG (Malaysia) SDN BHD, we select our software stack to ensure every project is sterile, silent, and ultra-efficient.

1. BIM & Coordination (The Digital Backbone)

These tools are the primary environment for Level of Development (LOD 400) modeling and multi-disciplinary collaboration.

• Autodesk Revit (MEP): The industry standard for BIM. It allows us to model ducts and pipes with "system intelligence," ensuring that airflows and pressure drops are calculated in real-time as the 3D layout evolves.

   

• MagiCAD for Revit: An essential extension used for advanced engineering. It provides localized duct and pipe sizing, high-fidelity symbol libraries, and automated calculation of Sound Power Levels—critical for ensuring a "Silent" office environment.

• Autodesk Navisworks: Our primary Clash Detection engine. It federates structural, electrical, and HVAC models to identify "Soft Clashes" (such as maintenance clearance violations) before they reach the site.

   

2. Load Calculation & Energy Modeling

With the enforcement of EECA 2024, load calculation software must now provide dynamic, hourly simulations to justify a building's Energy Intensity Label.

• Carrier HAP (Hourly Analysis Program): A cornerstone for peak load and energy analysis. We use HAP to simulate annual building performance, specifically for sizing AHUs and chillers based on Malaysia’s specific weather profiles.

• Trane TRACE 3D Plus: This tool bridges the gap between 3D building geometry and thermal simulation. It is used to run parametric studies, such as comparing the ROI of a Total Enthalpy Recovery Wheel versus standard ventilation.

   

• IES Virtual Environment (IESVE): The gold standard for high-performance buildings. It offers granular simulation of occupant comfort (PMV/PPD) and carbon emissions, essential for GBI or LEED gold-tier certification.

3. Psychrometric & Fluid Dynamics (CFD)

For sterile and critical environments, we use advanced simulation to visualize "invisible" performance.

• Autodesk CFD / Ansys Fluent: These Computational Fluid Dynamics tools allow us to simulate air movement within a space. We use them to verify that Laminar Flow is achieved in labs or that data center "Hot Aisle" containment is working effectively.

   

• Psychrometric Analysis Software: While integrated into HAP/TRACE, standalone tools like Hands-Down Psychrometrics allow for the rapid state-point modeling of the dehumidification process, ensuring the unit effectively strips moisture from the humid Malaysian air.

4. Specialised System Design

• Daikin D-Tools: Specifically utilized for VRV/VRF system layouts. It automates pipe sizing, refrigerant charge calculations, and ensures the system operates within the manufacturer's performance envelope.

   

• Hysopt: A powerful tool for Hydronic Optimization. We use it to simulate chilled water networks, ensuring that pumps and valves are perfectly balanced to minimize the building's total energy footprint.

   

5. Why the Software Choice Matters for 2026 Compliance

Under the latest statutory audits in Malaysia, the "Software Output" is the primary evidence for energy licensing.
