The Challenge

A major commercial real estate company managing 45 office buildings across multiple cities was facing rising energy costs and increasing pressure to meet sustainability targets. Their challenges included:

Inconsistent energy performance across similar buildings with no clear understanding of efficiency drivers
Manual HVAC scheduling that didn't adapt to actual occupancy patterns or weather conditions
Occupant comfort complaints despite high energy consumption in some buildings
Limited visibility into energy waste across their portfolio

Key Problem

Traditional building management systems operated each building in isolation, missing opportunities for portfolio-wide optimization and failing to balance energy efficiency with occupant comfort.

The Approach

The company implemented Duora's intelligent building optimization platform to create digital twins of their entire portfolio and optimize energy use while maintaining comfort standards.

The Results

After 18 months of implementation across the pilot facilities, the manufacturer achieved significant operational improvements:

22% Reduction

in portfolio-wide energy costs

$2.8M annual savings across 45 buildings

15% Improvement

in occupant satisfaction scores

Better temperature control and air quality management

30% Reduction

in peak demand charges

Through intelligent load shifting and demand response

18 Months

ROI payback period

Rapid return on platform investment

We now have unprecedented visibility into how our buildings actually perform. The platform doesn't just save energy—it makes our buildings smarter and our tenants happier.
