Why airflow inefficiencies drive up costs, compromise indoor air quality, and create hidden challenges for facility managers


Most commercial and institutional buildings today are designed with performance and efficiency in mind. Energy benchmarks, ESG goals, and occupant well-being are often front and center. But despite those efforts, one critical element of building performance is consistently underdiagnosed: airflow.


Poor airflow can silently affect every corner of your building’s operations — from higher energy consumption and HVAC maintenance costs to reduced indoor air quality (IAQ) and missed sustainability opportunities. It rarely shows up as a red flag on day one, but over time, it chips away at performance in ways that are both measurable and avoidable.


Inefficient Airflow Increases Energy Use — Even in “Efficient” Buildings

In many commercial buildings, HVAC systems account for roughly 30–40% of total energy consumption, according to Natural Resources Canada and ASHRAE. But when airflow is restricted, that percentage can climb significantly.


The most common culprits are high-resistance filters, dirty or aging ductwork, unbalanced systems, or outdated fans. These conditions increase static pressure, which forces HVAC fans to work harder and longer to achieve required airflow levels.


According to a study by the U.S. National Institute of Standards and Technology (NIST), buildings with airflow-related HVAC issues can see energy use increase by up to 30% compared to optimized systems. [1]


Even minor issues can have an outsized impact. A 100,000 sq. ft. office building experiencing elevated fan energy use due to clogged filters or inefficient duct design could face annual utility costs tens of thousands of dollars higher than necessary. For building owners managing multiple sites, that inefficiency compounds quickly.


Airflow and Indoor Air Quality Are Closely Linked


Buildings are dynamic systems, and air quality tends to suffer when airflow is compromised. Insufficient airflow can lead to poor ventilation, uneven air distribution, and pockets of stagnation in rooms or zones. These areas often experience elevated levels of carbon dioxide (CO₂), volatile organic compounds (VOCs), and particulate matter — especially in high-occupancy spaces.


A 2015 study from Harvard’s T.H. Chan School of Public Health found that employees working in well-ventilated buildings performed 61% better on cognitive tasks than those in typical buildings with poor ventilation and air quality. [2]


In schools, researchers have found that students in classrooms with improved ventilation perform better on standardized tests. [3] In healthcare facilities, inadequate air movement can increase the risk of airborne illness transmission.


Common complaints like “stuffy rooms,” temperature inconsistencies, or fatigue can often be traced back to airflow and ventilation issues — even when temperature setpoints and filtration standards are technically being met.


Poor Airflow Wears Down HVAC Systems Faster


Inefficient airflow costs more on your energy bill and accelerates mechanical wear and tear. When fan motors, compressors, and dampers are forced to operate under continuous load, components degrade faster than expected.


This leads to:

  • More frequent repairs and service calls

  • Shortened equipment lifespan

  • Greater downtime and occupant discomfort during peak seasons


A study from the National Air Duct Cleaners Association (NADCA) notes that air distribution restrictions are a key factor in premature HVAC failure and reduced system capacity. [4]


The cost of replacing a rooftop unit, for example, can range from $10,000 to $25,000, depending on building size and complexity — not including indirect costs from temporary system downtime.


Sustainability Targets Can Be Quietly Undermined


Many facilities today are pursuing ESG goals, LEED certification, or local emissions reduction mandates. But airflow inefficiencies can quietly work against those targets by increasing Scope 2 emissions (energy-related emissions) and filter waste.


High-resistance air filters, mainly traditional pleated filters, can contribute to this in two ways:

  1. Increased energy use due to pressure drop

  2. Frequent changeouts, leading to more waste and landfill contribution


According to a 2021 study in Building and Environment, filter pressure drop is one of the most overlooked contributors to unnecessary HVAC energy use — especially when filters are overused or under-maintained. [5]


If a building claims progress in sustainability, it’s important to ensure that filtration and airflow practices align with those claims—both from an energy and waste standpoint.


Missed Opportunities for Incentives and Cost Recovery


One of the lesser-known downsides of inefficient airflow is the lost opportunity to qualify for energy retrofit incentives.


Many utility and government programs across North America offer rebates, grants, or low-interest financing for businesses upgrading HVAC systems, controls, and low-pressure filtration. But to be eligible, buildings often need to demonstrate quantifiable improvements in system performance.


For example, Ontario’s Save on Energy Retrofit Program offers up to 50% of project costs for energy-efficiency upgrades, including those related to ventilation, air handling units, and demand control ventilation systems. [6]


Without data on airflow improvement or energy reduction — or without addressing underlying airflow inefficiencies — buildings may fail to qualify, leaving funding on the table.


Practical Steps to Address Airflow Challenges


The good news is that improving airflow doesn’t require a major capital project. Many impactful changes can be made within existing operations and maintenance cycles.


Here’s where most facilities can start:

  • Conduct a static pressure and airflow assessment to identify bottlenecks

  • Replace high-pressure filters with low-pressure, high-efficiency alternatives

  • Balance and tune your HVAC system, especially if zones have changed due to new usage patterns

  • Install real-time IAQ monitors to detect issues as they emerge, not after complaints arise

  • Track filter changeouts and energy use to capture data for future incentive applications


These strategies are already being implemented in facilities across North America — and in most cases, they deliver measurable improvements in energy efficiency, equipment reliability, and occupant satisfaction.



Airflow may not be the most visible part of your building, but it’s one of the most influential. When ignored, it quietly drives up energy costs, reduces system lifespan, and compromises air quality.


For facility managers and business owners focused on performance, sustainability, and operational clarity, airflow should be on the radar — not just as a maintenance metric but as a lever for long-term efficiency and resilience.


Addressing airflow challenges is a straightforward, high-ROI step that supports healthier, more cost-effective, and future-ready buildings.

Updated: Jan 28

Canadian companies required to report their carbon emissions face an increasing need to balance compliance with sustainability leadership. For larger businesses and public companies, carbon reporting is no longer about following regulations. It’s about meeting stakeholder expectations, addressing environmental challenges, and securing a competitive advantage in a rapidly evolving market.

Navigating Canada’s carbon reporting requirements might seem overwhelming, especially with the layers of federal, provincial, and international frameworks. But these challenges also bring opportunities—to improve operational efficiency, identify cost-saving measures, and build trust with investors and customers.


This guide aims to break down the complexities and provide actionable insights to help businesses comply while aligning with broader sustainability goals.


Why Carbon Reporting Matters

Carbon reporting has become a cornerstone of corporate accountability and a critical tool for mitigating climate change. In today’s market, stakeholders demand transparency regarding environmental impacts, which directly influences investor confidence, customer loyalty, and employee engagement. Public companies in Canada often find their carbon disclosure tied to financial performance metrics, and failure to comply can impact access to capital or even lead to penalties.


Beyond immediate compliance, carbon reporting reflects a company’s commitment to sustainability. By aligning business practices with Canada’s net-zero ambitions for 2050, companies can reduce their environmental footprint while positioning themselves as industry leaders.


The risk of inaction can be significant: businesses that fail to prioritize emissions reporting and reduction may face regulatory fines, reputational harm, and missed opportunities for innovation.


Overview of Canada’s Carbon Reporting Framework


Federal Regulations

Canada’s federal government has implemented comprehensive reporting programs to standardize emissions tracking and accountability. One of the cornerstone programs is the Greenhouse Gas Reporting Program (GHGRP). Managed by Environment and Climate Change Canada (ECCC), this program mandates facilities emitting 10,000 tonnes or more of greenhouse gases (GHGs) annually to submit detailed emissions data. For those emitting over 50,000 tonnes, third-party verification becomes a mandatory requirement, adding another layer of rigour to the reporting process.


The Canadian Net-Zero Emissions Accountability Act sets the national stage by establishing legally binding targets to achieve net-zero emissions by 2050. While primarily focused on government accountability, the Act’s associated policies filter down to businesses through funding programs, technology incentives, and strategic initiatives that encourage industries to adopt cleaner practices.

Another critical component is carbon pricing and offsets. The federal Output-Based Pricing System (OBPS) applies to large industrial emitters, requiring them to track emissions and offset excesses through credits or direct reductions. Companies need to report accurately and integrate these calculations into their financial strategies, as carbon pricing directly impacts operational costs.


Provincial and Territorial Regulations

Provincial and territorial governments add another layer of complexity. Regulations vary by region, reflecting local priorities and emissions profiles:


  • Ontario has introduced the Emissions Performance Standards (EPS), which require facilities emitting 10,000 tonnes or more of GHGs annually to report and adhere to sector-specific benchmarks. This system provides flexibility but also demands meticulous emissions tracking.

  • British Columbia focuses on public accountability through its Climate Change Accountability Act. While primarily targeting public-sector organizations, it offers guidelines for businesses interested in voluntary reporting, creating an environment of proactive sustainability.

  • Quebec operates a cap-and-trade system, one of North America’s most robust. Businesses emitting over 25,000 tonnes of GHGs annually are required to participate, submitting emissions data to ensure compliance with allocated caps and trading allowances as needed.


For businesses operating across provinces, this mosaic of regulations underscores the importance of tailored, region-specific reporting strategies.


International Reporting Standards

Canadian companies with global operations or international investors may also need to align with widely recognized frameworks like the Task Force on Climate-related Financial Disclosures (TCFD) and the Global Reporting Initiative (GRI). These frameworks emphasize the integration of climate-related risks into financial disclosures, offering guidance on best practices for reporting Scope 1, Scope 2, and Scope 3 emissions. Adhering to these standards can enhance credibility with international stakeholders and ensure readiness for emerging global regulations.


Key Steps for Compliance


1. Understand Your Obligations

Compliance begins with a thorough assessment of applicable reporting requirements. Start by identifying which federal, provincial, and international frameworks apply to your operations. This will depend on factors such as your industry, geographic footprint, and annual emissions levels. Companies operating in multiple provinces must account for variations in regional regulations and ensure that their reporting systems can handle these complexities.


2. Implement Robust Data Collection Systems

Accurate data collection is the foundation of effective carbon reporting. Businesses should invest in systems capable of tracking emissions across all scopes:


  • Scope 1 emissions cover direct emissions from owned or controlled sources, such as fuel combustion in company vehicles or manufacturing processes.

  • Scope 2 emissions refer to indirect emissions from purchased electricity, steam, heating, or cooling.

  • Scope 3 emissions include all other indirect emissions across the value chain, such as supplier activities, employee commuting, and waste disposal.

Advanced software solutions can automate data collection, reducing human error and improving reporting accuracy. For larger organizations, integrating emissions tracking into existing enterprise resource planning (ERP) systems can streamline operations and ensure consistency across departments.


3. Seek Third-Party Verification

Third-party verification is not just a regulatory requirement for some businesses; it’s also a critical trust-building tool. Independent audits lend credibility to your emissions data, reassuring investors and regulators that your disclosures are accurate and reliable. Verification partners, such as Bureau Veritas, SGS, and DNV, specialize in conducting thorough audits and providing certification for environmental compliance. These organizations often go beyond basic verification, offering insights into data gaps and areas for improvement, helping companies refine their reporting processes and maintain long-term accuracy.


4. Develop an Emissions Reduction Strategy

Carbon reporting is most impactful when paired with an actionable emissions reduction strategy. Use your emissions data to identify key areas for improvement, such as energy efficiency upgrades, renewable energy adoption, or supply chain optimization. For companies subject to carbon pricing, reductions can also translate into direct cost savings by lowering compliance obligations.


5. Stay Informed on Policy Changes

Canada’s regulatory landscape is constantly evolving to meet climate goals. Regularly review updates from Environment and Climate Change Canada, as well as provincial and territorial authorities. Engaging with industry associations can also provide early insights into upcoming policy shifts, ensuring that your organization remains ahead of the curve.


Benefits Beyond Compliance

Committing to robust carbon reporting and reduction offers far-reaching benefits. Transparent emissions disclosures can attract sustainability-focused investors who are increasingly scrutinizing ESG (Environmental, Social, Governance) metrics. Operationally, emissions tracking often highlights inefficiencies, leading to cost savings and streamlined processes. Furthermore, by taking a proactive stance on sustainability, companies enhance their brand reputation, fostering loyalty among environmentally conscious consumers and employees alike.
