Using the test results from the NRC and LMS, the study determined the amount of outside air required to be brought into a typical office space to achieve an equivalent risk reduction as using a ZenGUARDTM Enhanced Air Filter instead of a regular MERV 9 filter.
Key Findings
For a regular MERV 9 filter to achieve a reduction in infection risk consistent with a ZenGUARDTM Enhanced Air Filter, the percentage of outside air would need to be increased from 20% to 53%
By using a ZenGUARDTM Enhanced Air Filter to control infectious aerosols instead of increasing the percentage of outside air to achieve a similar risk reduction, the Company estimates that a typical office space of 10,000 square feet with 75 occupants can reduce HVAC energy consumption by approximately 62%
This reduction in energy consumption equates to monetary savings of approximately
'We have learned through the pandemic that viruses spread almost exclusively when people are indoors, and one of the most common recommendations from governments and industry associations to help reduce this risk is to maximize the amount of outside air being brought into buildings. One of the drawbacks of increasing the percentage of outside air into buildings - especially in very hot or cold climates - is the energy and emissions required to condition the air to room temperature,' commented
'With climate change and decarbonization being one of the biggest challenges facing society - and buildings contributing nearly 40% of global energy-related CO2 emissions - we need simple, scalable, carbon-conscious solutions that can control infectious aerosols and keep people safe. Whether it's higher rated MERV filters that require more fan power and energy, air purifiers that have a meaningful manufacturing footprint and need a power source - or increasing the percentage of outside air - typically all other methods of controlling infectious aerosols require additional energy and create emissions in some way. Based on this study and our team's research, we believe ZenGUARDTM Enhanced Air Filters are one of the only tools in the toolbox to help control infectious aerosols without significantly increasing energy consumption and emissions. And the ability for our product to accomplish this within existing HVAC systems that are already in most buildings means we can begin making a positive impact as soon as filters are replaced with the potential to quickly scale to many other buildings globally.'
Study Background
In addition to the assumptions disclosed in its
10-degreeC temperature gradient to condition air throughout the year
Average energy price of
Minimum outside air percentage based on guidance from ASHRAE 62.1
Monetary savings expressed in Canadian dollars
Other potential considerations related to buildings and air handling unit operation have not been included in order to isolate and quantify the energy and CO2 impact of outside air temperature adjustment
Canadian Federal Government Energy Savings Opportunity
Extrapolating these results to all buildings within the Canadian Federal Public Service, the Company estimates that energy consumption could be reduced by 455.7 million kWh, which translates to monetary savings of
The key assumptions underlying the Company's analysis for the Federal Government are as follows: 5,511 Federal government office buildings (calculated using 413,334 employees, 75 people per office and 10,000 square feet per office)
All federal government buildings where these employees work use MERV 9 filters currently and convert to ZenGUARD-enhanced MERV 9 filters
Space prototype assumptions consistent with those outlined in Study Background section above
The above analysis is disclosed for illustrative purposes only, and there can be no assurance that (i) the assumptions used by the Company in conducting its analysis are accurate and correct, (ii) the above analysis is or will be accurate or consistent with any third-party analysis, (iii) any third-party, including but not limited to, any governmental branch or office, awards or offers any contract.
