CASE STUDY
Kindred Hospital
Restoring comfort and HVAC efficiency for a long-term acute care hospital in San Antonio, TX.
Kindred Hospital in San Antonio is a four-story medical treatment facility equipped with a chilled water central plant and five rooftop air handlers. Over time, the facility experienced major issues with temperature control and energy efficiency because the duct insulation deteriorated.
The Challenge
Approximately 5,000 linear feet of rooftop ductwork had external insulation that had failed from prolonged exposure to the elements. The damaged insulation was falling off and severely degraded, leading to a 14°F temperature loss in the supply air ducts. This made it difficult to maintain indoor temperatures during peak cooling times, impacting patient comfort, system performance, and HVAC efficiency.
The Solution
Coat Zone® dealer, Energy Performance Solutions, developed a targeted restoration strategy:
- ThermalBlock® (or ThermalBlock by Coat Zone®) Coating: The team coated the cleaned ducts with our ThermalBlock® (or ThermalBlock by Coat Zone®) coating, creating a sealed, weather-resistant barrier that insulates and protects without traditional cladding.
- Insulation Removal & Surface Prep: The team removed all failed insulation and thoroughly cleaned the duct surfaces.
The Impact
- Temperature Loss Reduced from 14°F to 3°F: The restored ductwork dramatically improved system efficiency and performance.
- Improved Comfort: Kindred can now maintain comfortable temperatures throughout the facility, even during peak cooling demand.
- Month-Over-Month Energy Savings: Reduced air leakage and heat gain have translated into ongoing energy cost savings.
- Extended Equipment Life: By reducing system strain during extreme conditions, Kindred is also extending the life of its HVAC infrastructure and improving overall patient comfort.
Before
Before treatment, insulation had degraded from constant exposure to the elements, causing severe energy loss and reduced HVAC efficiency and performance.
After
Rooftop ductwork restored and protected with ThermalBlock® (or ThermalBlock by Coat Zone®) Coating—fully sealed, weather-resistant, and energy-efficient.
