109% of $21,500 target · IPMVP-verified · Installed May 2024 · 158 units · 168,000 ft²
A 158-unit senior living community in Central Michigan. 168,000 square feet. Every month, a meaningful portion of HVAC energy spend was going out the door uncaptured — measurable, recoverable, and until now, unaddressed. The goal: reduce energy costs by $21,500 per year while improving indoor air quality for residents and staff — without replacing existing equipment, pulling permits, or disrupting operations. Rensair supplemental air purification units were installed across common areas in a single day, sub-metered from the start. After 12 months of verified data: $23,426 saved. 109% of target. 38% IRR. NPV $128,296 over the 15-year equipment life. Lower energy costs and cleaner air — delivered simultaneously.
During the June 2025 Canadian wildfire event, outdoor PM2.5 levels across the Midwest exceeded 100 μg/m³. Rensair Core i devices at this community significantly reduced the impact of smoke and particulates indoors, protecting residents and staff throughout the day.
Key finding: When Rensair units were off overnight, PM2.5 rose rapidly toward outdoor levels. When activated, indoor PM2.5 was reduced by >50% within 1 hour and maintained at 0–10 μg/m³ throughout the day. Every reading is timestamped in Rensair Cloud — auditable by families, operators, and insurers. In a wildfire or smoke event, Rensair is the only senior living HVAC solution with a verifiable, real-time indoor air quality record.
Returns verified against IPMVP protocol — the same standard used by hospitals and institutional investors for investor-grade energy savings verification.
All figures are IPMVP-verified — the International Performance Measurement and Verification Protocol. IPMVP is the global standard for measuring and verifying the results of energy efficiency projects, used by hospitals, universities, and real estate investment trusts. Rensair is one of the only supplemental HVAC providers in the senior living category that publishes IPMVP-verified IRR data.
Rensair devices are installed alongside existing HVAC — not in place of it. No replacement, no permits, no disruption. Operational the same day.
Hospital operating room filtration standard. Captures 99.97% of particles including PM2.5, allergens, and viral particles. Validated by the Danish Technological Institute, IndoorScience (US independent lab), and independently tested by Eurofins.
Continuous 254nm UVC light sterilizes the HEPA filter 24/7, rendering captured pathogens permanently inactive. Safe for use with residents in the room — UVC exposure is contained within the unit enclosure.
Smart Demand Control Ventilation. Measures PM2.5, VOCs, temperature, and humidity in real time — not just CO&sub2;. Reduces HVAC runtime when indoor air quality is already clean, cutting energy spend without sacrificing air quality.
