A new year, new pressures

For facility and energy managers, 2026 is not just another lap around the operations cycle. The stakes are rising across the built environment: carbon targets are evolving from voluntary goals to enforceable standards, utility grids are growing more dynamic, and your systems are being asked to deliver more than comfort—they’re being asked to demonstrate climate performance.

This change comes at a moment when global energy demand is accelerating. In 2024, energy demand rose 2.2% globally (faster than the decade-long average), while electricity demand jumped 4.3%, driven by electrification, extreme weather, and digital growth. IEA In the buildings sector alone, electricity use increased by over 600 TWh (5%), accounting for nearly 60% of total growth in global electricity use. IEA Blob Storage And forecasts suggest this upward trend will continue: the U.S. Energy Information Administration projects that global energy consumption will grow through 2050, outpacing efficiency gains unless stronger policies intervene. EIA

The challenge is that these changes don’t arrive all at once or in obvious ways. They show up gradually—through updated codes, shifting tariffs, new equipment standards, and increasing expectations from tenants and investors. The upside is that facility and energy managers, once working mostly behind the scenes, are now central to turning sustainability commitments into measurable results.

Here are five sustainability trends shaping 2026, and why each matters for the decisions you’ll make in your mechanical rooms, dashboards, and boardrooms.

1. Building Performance Standards Move from Paper to Practice

A decade ago, sustainability reporting was a quarterly or annual exercise filed internally or sent to corporate. Today, Building Performance Standards (BPS) are shifting that paradigm: they tie a building’s actual energy use and emissions to regulatory thresholds, making performance more than just a nice-to-have.

Across the U.S., BPS and similar mandates now exist in nine localities and three states, with penalties or compliance mechanisms for underperforming buildings. (ACEEE) In Canada, cities like Vancouver have already adopted performance standards, and other municipalities are actively exploring similar rules. (Efficiency Canada) Natural Resources Canada also recognizes that BPS policies enable jurisdictions to regulate energy or emissions in existing buildings. (Natural Resources Canada)

Europe is several steps ahead. Through the EU Energy Performance of Buildings Directive, member states are required to set minimum energy performance standards for existing buildings and align them with long-term decarbonization goals. That trajectory suggests North America is likely to follow a similar path, with more cities and provinces phasing in binding performance requirements over the next decade.

For facility teams, this is a shift in mindset: hitting a design target isn’t enough. What matters now is day-to-day performance. Keeping HVAC systems tuned, filters low-pressure, ventilation right-sized, and carbon data tracked continuously.

Treat compliance not as a one-off capital project, but as a persistent operations program. Teams that build strong discipline in data, trending, and low-cost O&M measures (filter swaps, economizer tuning, drift checks) will free up budget (and carbon headroom) to take on higher-stakes retrofits later.

2. Grid-interactive buildings become the norm

The grid you’re tied into is no longer a fixed backdrop. It’s dynamic. As renewables rise, carbon intensity swings hour by hour. In many regions, the grid’s carbon intensity can vary by over 1,000 g CO₂/kWh between low and high hours. EnergyTag

This variability is why hourly accounting, not annual averages, is becoming the standard: studies find that relying solely on yearly emission factors can bias carbon inventories by as much as 35 %, especially in areas with high grid variability. itspubs.ucdavis.edu

For facility managers, your job isn’t just to reduce consumption, but rather to shift it. Running air handlers or pushing large loads at 3 p.m. on a carbon-intensive grid can erase much of the value of your efficiency gains. But shifting that same load to cleaner hours can multiply your CO₂e savings.

Buildings that provide demand flexibility (the ability to curtail, shift, or modulate loads) not only ease grid stress but also help integrate renewables and reduce emissions. ScienceDirect The U.S. DOE’s Grid-Interactive Efficient Buildings (GEB) initiative explicitly frames buildings as potential distributed energy resources (DERs) that can respond to grid signals. The Department of Energy's Energy

Facilities that align their systems with grid conditions will capture more carbon value, reduce costs, and position themselves for utility incentives and grid services.

3. Indoor Air Quality and Energy Are No Longer Trade-Offs

The pandemic showed that “just add more outside air” is not a sustainable strategy. It drove home the fact that healthier air doesn’t have to mean higher energy bills. In 2023, ASHRAE Standard 241 introduced the concept of Equivalent Clean Airflow (ECAi): a performance-based framework that lets you meet air quality targets with the right combination of ventilation, filtration, and air cleaning instead of defaulting to maximum outdoor air. (ASHRAE)

This matters even more in 2026 because the carbon penalty of over-ventilation is steep. Conditioning excess outside air can account for a significant share of building energy use, especially in regions with temperature or humidity extremes. U.S. EPA modelling has shown that raising outdoor air rates from 5 to 20 cfm per person can sharply increase HVAC energy costs, depending on the climate and system type. (EPA)

The opportunity is to deliver the same (or better) air quality at a lower energy cost. Low-pressure, high-efficiency filtration plays a central role here. Studies show that filter design, not just MERV rating, dictates pressure drop and energy impact. Well-engineered filters with optimized media and geometry can deliver higher capture efficiency at lower resistance than standard pleated filters, reducing fan energy while still supporting ASHRAE 241 clean-air goals. (ScienceDirect)

The play in 2026: pair low-pressure filtration with calibrated demand-controlled ventilation (DCV) and proven air cleaning technologies. Together, they provide safe indoor air with the lowest possible energy penalty. IAQ and carbon goals don’t have to compete. They can reinforce each other when filtration efficiency and system pressure are managed by design.

4. Refrigerant rules shift the replacement playbook

If you’re spec’ing new HVAC or refrigeration equipment in 2026, refrigerant selection matters just as much as capacity. Under the U.S. AIM Act, the EPA is phasing down production and consumption of high-GWP HFCs—aiming to cut them to just 15% of historic baseline levels by mid-2030s. US EPA That transition is pushing the market toward A2L (mildly flammable, low-GWP) alternatives like R-32 and R-454B. Energy Codes

For facility teams, two priorities stand out:

(1) Safety, training & codes readiness

A2L refrigerants bring new safety nuances. Contractors and service teams must be trained, and local codes (leak detection, ventilation, charge limits) must be understood and enforced. Manufacturers are already shifting product lines to A2Ls to align with the 2025 compliance timelines. Energy Codes

(2) Leak management as carbon strategy

Refrigerant emissions are Scope 1 emissions—direct, onsite greenhouse gas releases that come from leaks, servicing losses, or disposal. ASHE Because many HFCs have very high global warming potentials (GWP) (often hundreds to thousands of times higher than CO₂)a pound of refrigerant lost can translate into a large carbon penalty. GHG Protocol

Legacy systems may lose 20–30% of their refrigerant charge over time without an obvious performance impact. U.S. General Services Administration These silent leaks are hidden carbon drains, often overlooked in efficiency planning.

5. From Projects to Performance

Retrofitting systems may win attention, but the real win in 2026 is locking in performance over time. Field studies and commissioning guides show that, without sustained monitoring and correction, buildings can lose 10–30 % of their efficiency gains within a few years, due to drift, sensor faults, coil fouling, or control logic degradation.

Enter Monitoring-Based Commissioning (MBCx) and Fault Detection & Diagnostics (FDD). These aren’t big capital projects—they’re everyday practices that keep systems efficient. Research from ASME shows that automated fault detection in RTUs and HVAC systems can cut significant energy waste.

In one office building study, trend analytics flagged simultaneous heating and cooling, broken economizers, and poor control sequencing. Once fixed, the building’s energy use dropped by 10%. The takeaway is simple: continuous monitoring finds waste fast, and fixing it pays off immediately.

What this means for facility leaders in 2026:

Move away from treating projects as one-and-done.
Build dashboards that track energy, ventilation, fan motor indices, and carbon in parallel.
Use automated alerts to flag deviations in real time.
Make MBCx + FDD the standard part of your operations budget—not a side project.

Utility bills stay low, carbon footprints shrink, and your buildings stay compliant and efficient—without waiting for the next big retrofit.

2026 rewards operators

In 2026, sustainability progress will come from strong day-to-day operations. Facility and energy managers who focus on performance standards, grid-smart scheduling, healthy air, refrigerant planning, and continuous monitoring will find they already have the tools to deliver real results.

The equipment in your building doesn’t need to change overnight. What matters is how it’s managed. Every optimized filter, tuned control, and well-timed ventilation cycle adds up, lowering carbon, controlling costs, and building resilience.

This is the year where facility operations show their true strength: turning routine decisions into measurable sustainability gains.

Graphic of how an ionizer, fixed to a ceiling, works in removing small particles by electrically charging them to clup together and and on surfaces — Air ionizers use negative ions to remove small particles in the air. Releasing these ions can help reduce odours and make the air seem fresher.

In our ongoing pursuit of cleaner and healthier indoor environments, a multitude of technologies and devices have surfaced in recent years. One new emerging technology available on the market are “air ionizers”. You may have encountered these compact gadgets claiming to improve air quality and provide numerous health benefits. But what exactly are air ionizers? In this blog, we will explore the world of ionizer air purifiers, exploring their purpose, functionality, and potential advantages.

What are air ions?

In order to understand what air ionizers do, let’s first learn what “air ions” are.

Air ions are molecules with an electrical charge. They’re invisible molecules that float around in the atmosphere. Negative ions are molecules that have gained an electron; positive ions are those that have lost an electron.

An air ionizer is a device that releases negative ions into the air. The negative ions attach to tiny particles, like those in tobacco smoke.

This gives the particles an electrical charge, causing them to clump together and land on surfaces like:

walls
ceilings
floors
tabletops
curtains
carpets and rugs
metal collector plates in the device

Once the particles have landed on something, they can be cleaned up.

Are there benefits of investing in ionizer air purifiers?

Air ionizers use negative ions to remove small particles in the air. Releasing these ions can help reduce odours and make the air seem fresher.

According to a 2018 scientific review of ionization literature, negative ions have also been found to:

Inhibit viruses, bacteria, and mould species
Regulate sleeping patterns
Increase immune function
Support mood

The negative impacts of air ionization

While an ionizer may offer some limited advantages, this technology also has considerable downsides. It’s crucial to be aware of these drawbacks before considering installing this type of technology.

Emitting Ozone

Ionizers produce ozone when negative ions electrically charge airborne particles.

Although ozone may work against microorganisms like viruses, it’s also a lung irritant. Ozone can cause the muscles in the airways to constrict, trapping air in the alveoli. This leads to wheezing and shortness of breath. Depending on the level of exposure, ozone can:

Cause coughing and sore or scratchy throat.
Make breathing deeply and energetically more difficult, causing pain when taking a deep breath.
Inflame and damage the airways.
Make the lungs more susceptible to infection.
Aggravate lung diseases such as asthma, emphysema, and chronic bronchitis.
Increase the frequency of asthma attacks.

Long-term exposure to ozone is linked to the aggravation of asthma and is likely to be one of many causes of asthma development.

Ineffective for odours and gases

Ionizers don’t destroy odours and gases, including volatile organic compounds (VOCs). VOCs are considered to be indoor pollutants and may cause health problems and are released from products like paints, cleaning supplies, and adhesives. Unfortunately, ionizers are ineffective in reducing VOCs in the air.

What are the experts saying?

The EPA says air ionizers are relatively ineffective at removing larger particles like dust and pollen, and they are more suited to removing smaller particles such as tobacco smoke and smog, which measure between 0.01 and 0.1 µm/microns.

Ionizers cannot remove large particles that trigger asthma and allergy symptoms from the air. These include particles like:

dust
dander
pollen

Using an ionizer might not be helpful if you have asthma or allergies.

The main concern is the long-term health effects are largely unknown with many potential adverse effects in sight. ASHRAE and the CDC have not explicitly addressed ionizers in their standards or guidelines. While ASHRAE does not address air ionizers directly in its standards, it promotes the use of proven technologies and approaches to enhance IAQ. The CDC acknowledges that some air cleaners may generate ions in their operation but does not endorse their use.

It suggests selecting air cleaners certified by reputable organizations to ensure their effectiveness and safety.

It is important to consider the drawbacks of air ionizers before deciding to install this technology into your HVAC system. One significant concern is their emission of ozone, which can be a lung irritant and lead to respiratory issues such as coughing, wheezing, and shortness of breath. Long-term exposure to ozone can aggravate asthma and other lung diseases. Additionally, air ionizers are relatively ineffective at removing larger particles like dust and pollen, making them even less suitable for individuals with asthma or allergies. We also reviewed their ineffectiveness in reducing odours and gases, including volatile organic compounds (VOCs), which are indoor pollutants that can cause health problems.

Therefore, while air ionizers may offer some advantages in terms of air quality improvement, it is crucial to weigh their benefits against their potential risks. It is advisable to consider alternative technologies and approaches that are proven to enhance indoor air quality and have been endorsed by reputable organizations.
