The Cleaner Air for Schools program consists of two proprietary technologies unique to North American marketplace, which improve indoor air quality and impact student and staff health and safety. Duct Sealing and HVAC Optimization technology increases air volume and air exchange rates, regarded by experts as one of the best methods to improve indoor air quality and increase purification.



Ventilation air leakage is costing you more energy to operate school facilities


Ventilation represents 50-65% of your total energy spent to heat and cool school facilities. The unknown fact is that all buildings, new or old, lose 20-35% of their ventilation thorough leaks in the ductwork infrastructure.


  • Higher energy cost
  • Increased greenhouse gas emissions
  • Indoor air comfort challenges and compromised indoor air quality


The Aeroseal Duct Sealing application is a deliberate, proven and, measurable approach that has been deployed in over 10,000 projects across North America.

The Cleaner Air for Schools utilizes this award-winning technology as part of a turn-key 5 step process led by a qualified, experienced team of engineers and HVAC technicians who conduct pre and post audits, repair and seal air ducts to deliver a recommissioned ventilation system that delivers optimal efficiency and a detailed performance report. With very little time and attention from you and your team and no disruption to academic programming, the Cleaner Air for Schools program delivers the ability to increase airflow where needed, along with energy and GHG savings opportunities that help future-proof your schools.


1. Reduce energy cost by 12-15% of total energy budget

2. Reduce greenhouse gas emissions by 18-30%

3. Extend the lifespan of your equipment

4. Improve indoor air quality and wellness


Affordability – Simple paybacks in the range of 5-8 years.

Environmental – Reduced carbon footprint.

Energy Savings – Fiscal reduced operating costs.

Equipment Lifespan – Better operating equipment over time.

Safe and Effective – UL certified, meets health and safety accreditations.

Duct Leakage is a prominent issue for the commercial building industry. As you see here, ASHRAE estimates that most commercial buildings have duct leakage between 10-25%, which a recent study has quantified it as an $2.9 billion dollar problem annually.

In essence, duct leakage directly impacts the quality of your indoor air by contributing to cross-contamination issues that allow allergens, and viruses to travel throughout the facility. Naturally, this can be very problematic in educational and healthcare facilities where outbreaks can happen quickly.

Duct Seal

ALL BUILDINGS have leaky ductwork simply based of how ductwork is built and installed… and on top of that we are faced with the increased challenge of servicing older buildings that have mechanical and ductwork deficiencies that are gravely affecting their ability to deliver the right volume of air to each space. As a result, building operators are wasting energy, incurring unnecessary maintenance costs, and reducing the lifespan of their mechanical equipment.

But ABOVE ALL, this current pandemic and has shed light on the importance of indoor air quality and how we should all strive to provide healthy buildings. This technology just hits on all the right points. First of all, its practically the only solution that does not require any building or business disruption, and it is the most cost-effective way we’ve found as engineers to increase airflow and reduces cross contamination. What we love about it the most is that it effectively eliminates energy waste, reduces your ongoing utility costs, and helps to eliminate greenhouse gas emissions – we know 33% of emissions in buildings come from ventilation.

Turn-key Process

Our Duct Sealing Program is a 5-Phase implementation strategy that was developed to give you full sight of the project, while also providing each facility with vital information such as mechanical inspections and deficiency reports, testing and reporting on your existing air volume capacity, and a tailored engineered solution for each specific facility.

Nerva Energy remediates ductwork infrastructure and seals the ductwork itself from the inside out to virtually eliminate air leakage and all of the issues associated with it.

All of our work is validated by Nerva Energy which allows us to provide you with a comprehensive energy report at the end of each project that will highlight your building’s pre and post airflow and air exchange rates, as well as all of the remediation work that was done in the facility to achieve the final results.

Nerva Energy trained technicians perform the HVAC and aerosolized duct sealing components of the program.

Phase 4, the post project audit provides measurement and validation, which are later captured in the comprehensive energy report we discussed earlier.

And finally, communication is a big part of what we do. We have a complete department dedicated to assisting you with project communications. This includes reporting back to executives, communicating with the staff, students, community or the media.

Duct Sealing Can Help with Operational Costs

Duct sealing is helping building owners and operators in our communities to solve air flow issues – reduce energy consumption and greenhouse gas emissions – and optimize new construction.  We are starting to see more and more engineers specify duct sealing as a base part of their designs, because they realize that it is a common-sense measure include.   It takes the guesswork out of equipment sizing, allowing for a more optimal design, while simultaneously guaranteeing that the operation air handling systems and the associated duct work will comply with their intentions once the building is powered up.  Both of those benefits, combined with the lower usage of energy and reduced greenhouse gas emissions in order to satisfy the needs of the space and the users of the buildings, and no incremental increase to overall construction costs, produces a true win-win scenario.

Duct-sealing: A cost effective building measure to a) improve airflow and b) reduce energy costs and carbon.

  • Improves ventilation by up to 35% while decreasing energy use
  • Ensures that all of the air supplied and returned through the ventilation system is delivered to the spaces that people occupy in buildings (rather than leaking into ceilings and otherwise unoccupied mechanical spaces); and
  • Increases the effective air dilution rate within the building, which means that droplets with viral particles are more likely to be removed, filtered and dissipated, thereby reducing the risk of cross-contamination

 and how to Educate Your Staff about their use.

As you consider how to mitigate airborne and surface-based transmission of COVID-19 to provide a safe, healthy learning and working environment, you will need additional information.

Mohawk College has developed expertise and an applied research focus relevant to these technologies: the college is now working with three school boards that are installing these new systems and assessing their effectiveness in schools. Mohawk and Nerva will provide a future educational webinars on the process, technology and test results of these breakthrough air-quality solutions.
