Wildfire Smoke Is Changing How We Think About Buildings: Why Indoor Air Quality and Incentives Matter More Than Ever

Wildfire Smoke Is No Longer Just a Western U.S. Problem

During the summer of 2026, smoke from hundreds of Canadian wildfires spread across much of North America. Millions of people experienced unhealthy air quality as smoke blanketed major cities including Chicago, Detroit, New York City, Boston, Philadelphia, and Washington, D.C.

For many families and businesses, public health officials issued familiar advice: stay indoors, keep windows closed, and avoid strenuous outdoor activity.

But this raises an important question.

How well do our buildings actually protect us from wildfire smoke?

Increasingly, the answer depends on the age of the building, the HVAC system, the quality of air filtration, and how well the building has been maintained.

As wildfire events become more frequent, indoor air quality is becoming one of the most important—and often overlooked—aspects of building resilience.

Why Wildfire Smoke Is So Dangerous

Wildfire smoke contains gases, volatile organic compounds (VOCs), and microscopic particles known as PM2.5.

These particles are approximately thirty times smaller than the width of a human hair, allowing them to bypass many of the body's natural defenses.

Exposure to elevated PM2.5 levels has been associated with:

• Asthma attacks
• Respiratory infections
• Reduced lung function
• Cardiovascular disease
• Stroke
• Increased hospital admissions
• Higher risks for children, older adults, and individuals with heart or lung conditions

Because Americans spend roughly 90% of their time indoors, improving indoor air quality can significantly reduce exposure during smoke events.

Why Many Buildings Are Vulnerable

Most buildings were designed to manage temperature—not wildfire smoke.

Smoke enters buildings through several pathways:

• Gaps around windows and doors
• Aging building envelopes
• Roof penetrations
• Leaky ductwork
• HVAC systems drawing outdoor air indoors

Many older HVAC systems also use filters that are not capable of effectively removing PM2.5 particles.

Without proper filtration and ventilation controls, smoke can accumulate indoors, exposing occupants even after they leave the outdoor environment.

Building Upgrades That Improve Indoor Air Quality

Fortunately, many proven solutions are already available.

Better Air Filtration

Upgrading HVAC systems to higher-efficiency filters, such as MERV 13 or higher where equipment permits, can significantly improve the removal of fine particles.

HEPA Air Purifiers

Portable or whole-building HEPA filtration systems provide an additional layer of protection, particularly during severe smoke events.

Smart Ventilation Controls

Modern commercial HVAC systems can automatically adjust outside air intake based on outdoor air quality, reducing smoke infiltration while maintaining healthy indoor conditions.

Heat Pumps and HVAC Modernization

Many modern heat pump systems improve both energy efficiency and indoor air circulation, while newer HVAC equipment often supports higher-performance filtration.

Building Envelope Improvements

Air sealing, improved insulation, and high-performance windows reduce uncontrolled air leakage, helping keep smoke outside while lowering heating and cooling costs.

Indoor Air Quality Monitoring

Sensors measuring PM2.5, CO₂, humidity, and VOCs enable building owners to monitor conditions in real time and optimize HVAC operation during smoke events.

Financial Assistance Already Exists

One of the most surprising aspects of these upgrades is that many qualify for financial assistance.

Depending on location and project type, building owners may be eligible for:

• Federal tax credits
• Utility rebates
• State energy efficiency programs
• Commercial building incentive programs
• Multifamily housing incentives
• School and public building grants
• Building electrification incentives
• HVAC modernization rebates
• Building envelope improvement incentives

Programs offered by organizations such as NYSERDA, electric and gas utilities, and other state agencies can significantly reduce project costs. Similar opportunities exist across many states, although eligibility and funding levels vary.

The Challenge: Finding the Right Incentives

Despite the availability of funding, navigating the incentive landscape remains difficult.

Building owners often need to search through multiple federal, state, utility, and local websites to determine:

• Which incentives apply to their property
• Whether multiple incentives can be combined
• Eligibility requirements
• Application deadlines
• Required documentation

This complexity can discourage projects that would otherwise improve both public health and energy performance.

How Home Incentives Hub Can Help

Home Incentives Hub was created to simplify this process.

Our AI-powered platform helps homeowners, property managers, contractors, developers, and commercial building owners identify incentives available for specific properties and planned improvements.

Instead of spending hours researching multiple agencies, users can quickly discover programs that may support investments in:

• HVAC modernization
• Heat pumps
• High-efficiency filtration
• Ventilation upgrades
• Building envelope improvements
• Energy efficiency retrofits
• Building electrification
• Other qualifying projects

By making incentive discovery faster and more accessible, we aim to help building owners make healthier, more resilient, and more energy-efficient investments.

Looking Ahead

Wildfire smoke is becoming a recurring challenge across North America. At the same time, communities are investing in healthier buildings that can better protect occupants from environmental hazards.

Improving indoor air quality is no longer just a maintenance issue—it's a resilience strategy.

The good news is that many of the technologies needed already exist, and financial assistance is often available to help offset the cost.

The next challenge is making those opportunities easier to find.

At Home Incentives Hub, that's exactly what we're building: an easier way to connect property owners with the incentives that can help create healthier, safer, and more resilient buildings for the future.
