Challenges

• +2000 individually controlled 1-10 ton capacity R-22 water-source heat pumps
• -40 tenant comfort complaints per month due to poor temperature control
• +20 equipment failures or replacements per month
• No building management system, rising energy costs and budget pressure

HVAC Copilot Initial Findings

• 100% of monitored equipment ran incompatible operating modes (i.e. cooling on cold day, heating on hot days simultaneously heating and cooling in the same room)
• 65% of equipment had a refrigerant leak
• 30% of equipment was short-cycling
• Preventative maintenance alert prevented +$1K in failures and replacement parts

Building-Wide Savings

As Thalo works with the onsite team to roll out building-wide significant operational and energy savings are projected:

• $145,000 Energy Savings
• $169,380 Parts + Materials Savings
• $119,200 Eqv. Labor Savings
