## The Situation

### 2,000+ Unmanaged Heat Pumps and No Building Management System

A 120K sq ft commercial office in the Northeast operated over 2,000 individually controlled R-22 water-source heat pumps ranging from 1 to 10 tons. With no building management system in place, the facilities team had no visibility into equipment health — only the complaints and failures that surfaced organically.

The result: approximately 40 tenant comfort complaints per month, 20+ equipment failures or replacements per month, and steadily rising energy costs with no clear path to resolution.

## The Approach

### HVAC Copilot Initial Deployment

Thalo's HVAC Copilot was deployed across a monitored subset of the portfolio. Within the initial deployment window, the system surfaced a level of equipment dysfunction that had been invisible to the facilities team entirely.

100% of monitored equipment was running incompatible operating modes — units simultaneously heating and cooling, or operating counter to actual building demand. 65% had active refrigerant leaks. 30% were short-cycling. A preventative maintenance alert caught an impending failure worth over $1,000 in parts and replacement costs before it occurred.

## The Result

### $433K+ in Projected Building-Wide Savings

As Thalo works with the onsite team to roll out building-wide, the initial findings project significant operational and energy savings: $145,000 in energy savings, $169,380 in parts and materials savings, and $119,200 in equivalent labor savings.

With over 2,000 units to address and a clear diagnosis of what's wrong across the portfolio, the property now has a data-backed roadmap for systematic remediation — and the visibility to prevent the next generation of failures before they generate complaints.
