Operational Excellence

A leading asset management group partnered with Cortex to enhance energy efficiency and operational performance at their Midtown Manhattan Class A office building.

The challenge

Before using Cortex, building owners had set ambitious sustainability goals to cut costs and reduce energy waste. They faced challenges translating these goals into actionable steps due to a lack of real-time energy monitoring tools, and low confidence to implement operational changes resulting in high costs, energy consumption, and tenant dissatisfaction.

The solution

Cortex integrated its platform into building infrastructure to provide engineers with energy insights, leading to operational strategy changes. They collaborated to beta-test and validate energy management protocols.

Start Up Recommendation

Adjusted HVAC system start-up times using AI/ML to reduce electric consumption while still meeting lease obligations temperatures.

Airside Turndown

Scheduled earlier fan turndown times on Fridays when building occupancy was lower, reducing energy use without impacting tenant comfort.

Overnight Shutoff

Leveraged automated shutoff alerting to identify and mitigate ghost energy consumption during unoccupied hours.

Chiller Coasting

Implemented chiller coasting times between 7:15pm and 7:45pm to improve cooling system efficiency.

$307,000 improved electric efficiency reflected in reduced utility bills 
2.2M kWh saved over 9 months of leveraging Cortex recommendations 
15% decrease in tenant hot and cold calls
