Class A Office Towers

Class A tenants notice everything — a two-degree drift at 3 PM, an economizer stuck at minimum OA, a VAV that hunts. We keep central plants, floor VAVs, and BAS sequences tuned to the lease-comfort clause, not the datasheet.

Where facilities like yours get stuck

Four problems we hear on the first walk.

01

Tenant complaint cycles

Every complaint is a leasing risk. Zoning conflicts, drafty perimeters, and hot-spot conference rooms trace back to VAV setup, not equipment size.

02

After-hours HVAC billing

Property teams need clean, auditable overtime HVAC hours by tenant — tied to BAS, not spreadsheets.

03

LEED / ENERGY STAR score pressure

One drifting economizer or a bank of oversized fans can cost a full ENERGY STAR point.

04

Aging chilled-water plant

Original 30-year-old chillers running at 0.85 kW/ton when the market is at 0.45. Repositioning capital demands a payback story.

How we deliver

The playbook, on the record.

  • Sequences rewritten to ASHRAE Guideline 36 with owner-signed intent
  • Perimeter VAV recommissioning — measured air balance, not thermostat swaps
  • Tenant-metered after-hours HVAC integrated to your billing platform
  • Chiller plant repowering with variable-primary + free cooling where the tower allows
  • ENERGY STAR benchmarking + M&V loop tied back to BAS trends
  • Filter and coil program that keeps design airflow past year three, not just week one
