At The Horizons apartments in Virginia, the hydronic HVAC infrastructure was failing. The owner decided to convert to a more energy-efficient system that would also provide residents with year-round or “four season” control of their heating and cooling. But every contractor’s bid for their planned upgrade exceeded the budget.

That’s when SageWater put its design-build capabilities to work. Among the options we engineered, the owner chose a highly efficient Water Source Heat Pump (WSHP) system. To deliver it, we upgraded the property’s utility plant—decommissioning the chiller and installing new pumps, boilers, and heat exchangers. We also replaced the system piping and swapped fan coil units with WSHPs, all while residents remained in their homes.

The owner selected SageWater because no other contractor provided an innovative, turnkey solution that met their goals and budget. We exceeded their expectations, providing a creative design and working successfully in occupied buildings with dedicated project managers and construction crews to deliver a high-quality renovation under one contract, with one point of accountability.
