ZENTEK COMPLETES CASE STUDY ON HVAC TOTAL COST OF OWNERSHIP SAVINGS FOR THE CITY OF TORONTO

Zentek Ltd. completed a case study based on the City of Toronto highlighting the economic and environmental benefits related to using MERV (minimum efficiency reporting value) 9A filters compared with using MERV 13 filters. The study quantifies cost-savings, and reductions in carbon emission and waste assuming the City of Toronto is currently using MERV 13 filters in all its buildings and switches to MERV 9A filters.

Key findings:

• Annual cost-savings of over $40-million from:
  • Significantly reduced labour costs due to filters being changed every six months rather than every three months;
  • Reduced expenditures on air filters from replacing filters every six months rather than every three months;
  • Reduced energy requirements and costs due to improved air flow;
  • Lower waste disposal costs from fewer filters being used.
• Reduced energy requirements and associated carbon emissions of 3,029 tonnes of CO2 (carbon dioxide) equivalent -- an amount that takes 49,976 newly planted tree seedlings growing for 10 years to absorb;
• Reduced landfill waste by approximately 947 full dumpsters.

"Keeping people safe indoors while also being mindful of building decarbonization is incredibly important and presents a unique challenge to property managers. To help address this, we need simple, scalable, carbon-conscious solutions that can control infectious aerosols and keep people safe," remarked Greg Fenton, chief executive officer of Zentek. "Our aim is to help control infectious aerosols within existing HVAC [heating, ventilation and air conditioning] systems without significantly increasing energy consumption and emissions. We believe our latest study does an excellent job of highlighting the potential benefits of using MERV 9A filters compared to MERV 13 filters for Canada's largest city."

ZenGUARD overview

Zentek aims to provide property managers with the ability to use a MERV 9A filter instead of a MERV 13 filter in HVAC systems to keep patrons safe from pathogens, with the additional benefit of reducing costs, waste and emissions.

Case study assumptions:

• City of Toronto has 102,257,149 square feet of building space;
• Energy calculations are from previously referenced in-house models using third party validated data;
• CO2 measured in terms of 10,000-square-foot spaces and extrapolated to total square footage;
• Any emissions data were calculated in accordance with EPA (Environmental Protection Agency) guidance;
• Waste savings measured using the volume of a standard four-yard dumpster;
• Filter size of 24 inches by 24 inches by two inches used in all buildings;
• One filter per 2,000 square feet of building space.

The ZenGUARD enhanced air filter product is currently being assessed for registration under the Pest Control Products Act (Canada).

It cannot be manufactured, imported, distributed or used in Canada at this time, unless explicit authorization has been obtained from Health Canada to use this product for the purpose of conducting research under the Pest Control Products Regulations.
