Indirect Evaporative Cooling for Renovations
Renovations offer a critical opportunity to upgrade outdated systems and future-proof buildings for energy efficiency, occupant comfort, and sustainability. However, retrofitting traditional HVAC systems into older structures often leads to high costs, complex construction, and major disruptions.
At S Flo, we offer a better way to renovate and modernize building cooling systems. Our indirect evaporative cooling solutions(IEC) deliver high-performance, eco-friendly cooling with minimal structural impact, lower installation costs, and significant energy savings — all while preserving the original integrity and character of your building.
Why Choose Indirect Evaporative Cooling for Renovation Projects?

Minimal Structural Disruption
Our modular, lightweight IEC systems integrate easily into existing structures without extensive ductwork, roof reinforcements, or major modifications.
Perfect for:
− Historic restorations
− Commercial offices
− Retail centers
− Schools and educational buildings
− Industrial warehouses

Major Energy and Operational Savings
Cut cooling energy consumption by 50–70% versus traditional HVAC retrofits.
Meet or exceed modern energy efficiency codes with ease.
Lower operational costs without sacrificing performance.
Real-World Example:
“A historic office building in Denver upgraded to S Flo’s IEC systems and slashed cooling costs by 62%, while achieving LEED Gold certification after renovation.”

Enhanced Indoor Air Quality
Delivers a constant flow of fresh outdoor air.
Filters out pollutants, allergens, and odors.
Creates healthier, more comfortable spaces for:
− Tenants
− Students
− Shoppers
− Employees

Fast, Non-Disruptive Installation
Pre-engineered modular units speed up installation.
Retrofit timelines are shortened, minimizing business interruptions and tenant inconvenience.

Eco-Friendly Cooling Technology
Reduces reliance on chemical refrigerants like CFCs and HFCs.
Supports LEED, WELL, ENERGY STAR, and local green building certifications.
Helps building owners meet carbon reduction and ESG targets.
How S Flo’s Indirect Evaporative Cooling Works in Renovations?
Outdoor air is drawn into the IEC unit.
It passes through a high-efficiency cooling heat exchanger, where evaporation cools a secondary air stream without direct contact with water.
Cooled, dry air is distributed into the renovated space.
Exhaust air and waste heat are efficiently vented outside.

Result
Your warehouse benefits from fresh, dry, and cool air without the humidity issues of traditional systems.
