Controlium Solutions 
Three or four contractors, or one
Controls depth, in house
BACnet, centralized system control and heat-recovery integration — the hardest skill to hire, and where most installations fail at startup.
Energy and decarbonization, in house
Energy modelling, electrification strategy, and support for Zero Carbon and LEED targets — carried inside the design team.
Design-build and negotiated work
Engaged directly by owners, developers and general contractors — not a hard-bid commodity shop.
What we deliver under one contract
MEP Engineering
Ingénierie MEPIn-house mechanical, electrical, and plumbing engineering.
HVAC-R Installation
Installation CVC-RCertified sheet metal workers and refrigeration technicians. Executed by our own team.
BMS Controls
Contrôles BMSDesign, installation, and commissioning of BMS / DDC systems. Service after installation.
Energy and Decarbonization
Énergie et décarbonationEnergy analysis, modelling, and support for Zero Carbon v4 and LEED targets.
Delivered at scale
Multi-residential VRF network
700+ outdoor heat-pump units and hundreds of indoor units, delivered floor by floor over roughly 20 months of active construction.
Case study B
Twin-site residential complex
500+ indoor VRF units across two sites, with a centralized building-management layer and 700+ work orders.
Case study C
Rooftop mechanical + BMS
Rooftop air-handling units, a VRF network and 100+ destratification fans, integrated and commissioned zone by zone.
Energy performance, held by the design team
Performance targets are set inside the design team, not audited by someone else afterwards — which is what makes an electrification or Zero Carbon pathway survive contact with the equipment schedule.
How we hold performanceDesign, coordinate, install, commission
Engineer & coordinate
Mechanical design coordination with the general contractor and trades; equipment selection and staging.
Install at scale
Floor-by-floor, zone-by-zone execution by dedicated crews: refrigerant, ductwork, controls wiring and equipment set.
Commission & verify
System startup by zone, pressure and leak verification, controls integration, and fault clearing before handover.
Train & support
Operator training on control systems and sequences at handover, then ongoing service.
Every project is tracked work-order by work-order — scope, labour, materials and commissioning steps documented from first delivery to final startup. That discipline is why our large installations stay coordinated.
One integrated system, proven at startup
Full-stack, one contractor
Mechanical, ventilation, controls and commissioning under one roof — and one contract. Most competitors can credibly claim one or two of those roles.
Scale and density
Installations spanning hundreds of units, multiple sites and thousands of work orders. Small shops cannot staff or coordinate this.
Controls and BMS depth
BACnet, centralized system control and heat-recovery integration — the hardest skill to hire, and where most installations fail.
We commission what we install
Startup, balancing, fault-clearing and operator training at handover. Not a hand-off to someone else.
Documented, auditable delivery
Every project tracked work-order by work-order, from first delivery to final startup. Coordination you can see.
