The shift to all-electric kitchens is a powerful step towards decarbonization, eliminating fossil fuels, reducing greenhouse gas emissions, and enhancing energy efficiency. Spring Air Systems ecology units play a pivotal role in this transition by enabling the return of filtered kitchen exhaust air to indoor spaces—provided compliance with NFPA 96, the Ontario Building Code (OBC), and ASHRAE standard 62.1.
How Spring Air Systems Drives Decarbonization
- Advanced Filtration: Multi-stage systems utilizing high MERV filtration remove grease, smoke, and odors, supporting ASHRAE 62.1 indoor air quality standards. Specific odor control options are available as well as either potassium permanganate filter sections, or spray.
- Higher Operating Efficiency: Recirculating 80% of filtered kitchen exhaust significantly reduces MUA size and operational costs, while maintaining ASHRAE 62.1 ventilation requirements (6.2.2.1 requires a minimum of 7.5 CFM/person and .12 cfm/ft2 for ventilation in kitchens).
- The average 5’ kitchen exhaust hood would require approximately 1250 CFM of EA, and with an all electric appliance lineup you could recirculate 1000 CFM.
- This significantly reduces the MUA size and associated ductwork requirements as well operating costs.
- Electric heating becomes an effective option with such small OA tempering requirements.
- Reduced Emissions: Electric appliances and makeup air units combined with efficient filtration lower environmental impact.
Regulatory Considerations
- NFPA 96: Requires outdoor exhaust for grease-laden vapors. Recirculating air is possible only with Authority Having Jurisdiction (AHJ) approval, proving fire safety and contaminant removal.
Best Practices
- Collaborate Early with AHJs
Engage with local authorities early to confirm compliance and streamline project approvals. - Leverage Energy Recovery Systems
Utilize Spring Air Systems’ innovative energy recovery solutions to design for 80% air recirculation. - Ensure Ongoing Maintenance
Regularly test and maintain systems to meet air quality, safety, and performance standards.
The Bottom Line
Spring Air Systems ecology units provide a sustainable, energy-efficient solution for all-electric kitchens, helping you decarbonize your kitchen while saving on capital and operational costs. By effectively filtering and recirculating kitchen exhaust air, these systems support compliance, enhance air quality, and reduce environmental impact—all without compromising performance.
Make the smart move toward decarbonization. Choose Spring Air Systems to power the kitchens of tomorrow.
