HVAC systems designer with embedded BMS/controls — from concept to commissioning I design HVAC systems and the controls that make them reliable in real buildings: residential, warehouses, offices, and commercial facilities. With 23+ years in HVAC engineering and 12+ years in cost-effective embedded controllers (ESP32, Arduino, Raspberry Pi), I cover both the mechanical design and the automation layer — so the system works as intended after installation, not only on paper. What I typically deliver • HVAC design in Autodesk AutoCAD MEP (heating, cooling, ventilation) • Building controls / BMS logic for HVAC, boiler rooms, and heat pumps • Custom controllers and PCB prototyping when off-the-shelf hardware is a poor fit • Energy modeling with OpenStudio + EnergyPlus for loads and efficiency decisions • Legacy TAC Xenta / Schneider Electric Xenta and TAC Vista application work (16+ years) How I work Designs I create are often assembled and maintained under my supervision, so decisions account for installability, service, and long-term reliability — not just drawings. Recent related work on Upwork includes greenhouse ventilation calculations, energy simulation for a resort dome project, and embedded/PCB control work for sensors and flow systems. If you share building type, climate/location, and whether you need design, controls, energy model, or all three — I’ll reply with a clear scope and approach.
