Mechanical Engineering
From central plants to single-zone retrofits, we design HVAC infrastructure that performs under code, under load, and under scrutiny. We size for performance, model for efficiency, and detail for the contractor who will actually build it, across new construction, renovations, mission-critical retrofits, and process facilities.
Thermal comfort is no longer a luxury. Indoor air quality and temperature directly affect occupant health, comfort, and productivity. We design innovative solutions that ensure comfort while keeping construction and operating costs low and increasing return on investment.
Our Approach
How We Work
Every mechanical design starts with a real load model, not a rule of thumb. We evaluate system alternatives against first cost, operating cost, maintainability, and the owner's decarbonization targets before a single duct is drawn.
- Load analysis & energy modeling on every project
- Equipment selections coordinated with structure & architecture
- Sequences of operation written for the operator, not the binder

Why Owners Choose KeRi
Right-Sized Systems
We model loads, not rules of thumb, equipment sized for real diversity saves first cost and operating cost for the life of the building.
Built for the Field
Details, clearances, and access drawn for the contractor who installs the system and the operator who maintains it.
Energy First
Every system is screened against energy code and decarbonization targets from the first sketch, not as an afterthought.
