Commercial HVAC Engineering for Utility Buildings

I support building owners, installers and consultants with technically solid HVAC engineering deliverables — aligned with Dutch NEN / ISSO standards and ready for field installation.

Heat loss & cooling load calculations

Accurate sizing for heating and cooling systems in offices, schools and commercial buildings. Deliverables include detailed reports and transparent assumptions.

HVAC system design

From concept through detail: system selection, schematics, P&ID, BOM, and performance notes for tender or execution.

Controls / BMS concept

Control narrative, I/O lists, and functional descriptions prepared for commissioning and integration with Building Management Systems (BMS).

CAD & Revit documentation

Consistent layer naming, clear schematics and coordinated layouts. Documentation ready for installers and consultants.

Frequently Asked Questions about HVAC Engineering

1. What is the difference between a heat loss calculation and a cooling load calculation?

A heat loss calculation determines how much heat a building loses during winter — essential for heating system sizing. A cooling load calculation defines internal and external heat gains during summer, ensuring chillers or heat pumps are properly sized. Both form the foundation of reliable HVAC design in commercial buildings.

2. How is the capacity of a heat pump or chiller determined?

Capacity is based on calculated loads, ventilation requirements, and building operation schedules. Calculations follow Dutch NEN and ISSO standards, ensuring energy-efficient and comfortable systems.

3. What exactly does an HVAC engineer deliver?

Deliverables include calculations, schematic diagrams, bills of materials, BMS/controls documentation, and AutoCAD or Revit drawings. These documents ensure clarity for installers and consultants during design and execution.

4. Why is a good controls or BMS concept important?

A Building Management System (BMS) ensures that boilers, heat pumps, AHUs, and chillers work in coordination. Without a coherent control strategy, energy is wasted and comfort drops. Each project includes a functional description, I/O list, and control logic ready for commissioning.
