What happens when a multifamily building restores the performance of its central ventilation system?
At One50 West End Avenue in New York City, managed by AKAM, a leading NYC-based property management company, the answer was clear:
✅ 28.2% verified REDUCTION in steam consumption
Not modeled. Not estimated. Measured in a fully occupied cooperative building after the central ventilation system was restored using Aeroseal.
What makes the result even more noteworthy is the context: while a portfolio of comparable AKAM-managed buildings experienced an average 15% INCREASE in steam consumption during the same period, One50 West End Avenue moved in the opposite direction.
The project reduced energy waste without major construction, disruption to residents, or system replacement.
Real building. Real operating conditions. Real results.
