Case Study
Long-Running Renewable Systems at the Depot
Roughly sixteen years after installation, the Depot Coffee House's solar, heat-pump, and ventilation systems were still doing their job.

The Building
The Depot Coffee House occupies a restored brick railroad depot in Hopkins. The City of Hopkins dates the building to 1903. It now serves as a neighborhood coffeehouse, regional trailhead, arts venue, and home for youth programming.
The Project
In an August 2024 visit, Nick Bender checked in on a project he had worked on roughly sixteen years earlier. The building's energy systems included rooftop solar, an air-source heat pump, and an air-exchange system.
The source does not provide equipment models, energy data, or Nick's exact contractual scope. What it does show is the value of returning to an older project to see how the complete system is holding up over time.
The Result
At the time of Nick's visit, all three systems were still operating. For a historic public building, that longevity is a useful reminder that good building-performance work is not only about what runs on installation day. It is about creating a system that continues to serve the building years later.

List of Upgrades
Solar Energy
Rooftop solar was included as part of the building's long-term energy strategy.
Air-Source Heat Pump
A heat-pump system provided efficient heating and cooling for a historic community building.
Air Exchange
A dedicated air-exchange system supported fresh-air ventilation in an active public space.
A 2024 check-in found the solar, air-source heat pump, and air-exchange systems still operating roughly sixteen years after the project.
