HVAC engineered from a logger study, not a walk-through.
HVAC is usually the biggest energy line in a building and the hardest to see into. We log the plant and air systems first, then fix what the data shows: airflow, drives, sequences and controls.
HVAC & Controls, engineered and installed by EverWatt
Plant optimization
Boiler and chiller plants converted to variable flow, staged and sequenced to the load they actually see.
Variable-frequency drives
VFDs on fans and pumps, so motors run at the speed the building needs instead of full speed all day.
Ventilation resets to code
Air-change rates brought to current code (including the California Mechanical Code for healthcare), with testing and balancing.
Steam and hot-water automation
Control added to steam and heating systems that were built before controls existed.
Economizer and damper repair
Free cooling that actually works, with dampers and linkages that stroke the way they should.
Retro-commissioning
Overrides, fights between units and 24/7 schedules found and fixed.
One contact from the first site walk to verified savings.
Log
Weeks of logging on the plant and air systems.
Model
Savings calculated measure by measure, reviewed by the utility.
Build
Our engineers and crews install and commission.
Verify
Results measured at the meter.

We just replaced equipment. Is there still savings?
Usually, yes. New equipment running on old sequences or fixed dampers wastes as much energy as old equipment. Most of what we find is in control, not hardware.
Can you work in a hospital?
Yes. Most of our HVAC work is in healthcare. We phase work around patient care, coordinate with facilities and infection control, and bring ventilation to current code.
How is this paid for?
Many HVAC measures qualify for utility incentives and zero-interest On-Bill Financing. San Leandro Hospital's project was fully financed with no capital outlay.
