The challenge

With its 24/7 demands and different requirements for guest rooms, common areas, and dining facilities, the Carriage House Hotel’s goal was to reduce high energy costs while maintaining guests’ comfort.

The solution

A thorough energy audit identified several key areas for improvement.

• Basement subpanel: External cellular towers on the roof were responsible for 45 percent of the basement subpanel's energy draw, providing an opportunity for cost recovery.
• Dining facility submetering: The independently owned restaurant accounted for seven percent of the total energy consumption, allowing the hotel to bill that cost accurately.
• Guest room optimization: Occupancy-based sensors were installed in guest rooms to control heating and cooling units, making usage more efficient and reducing wear and tear.

The results

Reduced consumption and new ways to recover costs led to significant savings. Improved operational efficiency for heating and cooling units lowered maintenance costs and prolonged the units’ lifespans. More sustainable operations demonstrate the hotel’s commitment to environmental responsibility.

And that’s just the beginning. Once occupancy-based lighting controls for common spaces are added, future savings will increase.
