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.

Older building rooftop ventilation — Older buildings often face several air quality challenges due to years of accumulated wear and tear and outdated construction practices.

Indoor air quality (IAQ) is a critical aspect of building management that directly affects the health and well-being of occupants. This importance is magnified in older buildings, where outdated infrastructure, prolonged wear and tear, and the presence of potentially hazardous materials can significantly compromise air quality.

For building owners and facility managers, ensuring good air quality in older buildings is not just a matter of comfort; it is essential for maintaining the health and safety of those who live and work in these environments. Poor IAQ in such buildings can lead to various health issues, decreased productivity, and non-compliance with modern regulatory standards, making it a fundamental concern that demands urgent action.

Common Air Quality Issues in Older Buildings

Older buildings often face several air quality challenges due to years of accumulated wear and tear and outdated construction practices. These issues can severely impact IAQ, making it crucial to identify and address them to ensure a healthy living and working environment. Common air quality problems in older buildings include:

Mold and Mildew: Due to water damage or high humidity, mold and mildew can thrive in older buildings, releasing spores into the air.
Dust and Allergens: Accumulated dust and debris in older buildings can harbor allergens, worsening respiratory conditions.
Outdated HVAC Systems: Inefficient and outdated HVAC systems may not adequately filter air, leading to the circulation of pollutants.
Asbestos and Lead: Many older buildings still contain asbestos and lead-based materials, which can pose serious health risks if disturbed.
Chemical Pollutants: Use of old construction materials and maintenance products can introduce volatile organic compounds (VOCs) into the indoor environment.

Health Impacts

The poor indoor air quality in older buildings can lead to numerous health problems for occupants, emphasizing the need for immediate attention. Exposure to contaminants commonly found in older buildings can result in a range of adverse health effects, including:

Respiratory Issues: Exposure to mold spores, dust, and other airborne pollutants can exacerbate asthma, bronchitis, and other respiratory conditions.
Allergies: Increased levels of allergens such as dust mites and pollen can trigger allergic reactions, leading to discomfort and reduced quality of life.
Productivity Loss: Poor air quality can cause headaches, fatigue, and difficulty concentrating, reducing productivity and overall well-being.
Long-Term Health Risks: Chronic exposure to pollutants like asbestos and lead can lead to severe health conditions, including cancer and neurological disorders.

Regulatory Concerns in Older Buildings

Ensuring compliance with air quality standards and regulations is critical for older buildings, as failing to meet these requirements can lead to significant health risks and legal issues. Both Canada and the US have established stringent guidelines to protect indoor air quality, but older buildings often struggle to meet these standards due to several factors:

Canadian Regulations:

Health Canada: Sets IAQ guidelines that include maximum acceptable concentrations for common indoor pollutants such as carbon monoxide, formaldehyde, and mold spores. Older buildings might not have adequate ventilation systems to meet these guidelines.
National Building Code of Canada: Requires proper ventilation and air filtration systems to maintain acceptable IAQ. Many older buildings were constructed before these codes were established, leading to inadequate ventilation and outdated HVAC systems.
Provincial Regulations: Provinces like Ontario have specific requirements under the Ontario Building Code, focusing on ventilation and mold prevention. Older buildings often lack the modern infrastructure necessary to comply with these regulations. The Canadian Centre for Occupation Health and Safety provides a great resource to link to provincial guidance.
See also ASHRAE Standards below

United States Regulations:

Environmental Protection Agency (EPA): Establishes IAQ guidelines and provides resources for maintaining healthy air in buildings. The EPA’s standards include acceptable levels for various indoor pollutants. Older buildings often have outdated or poorly maintained HVAC systems that fail to filter out pollutants effectively.
Occupational Safety and Health Administration (OSHA): Mandates safe working conditions, including standards for indoor air quality in workplaces. Older buildings may not meet these standards due to deteriorating infrastructure and lack of modern air purification systems.
ASHRAE Standards: The American Society of Heating, Refrigerating, and Air-Conditioning Engineers sets voluntary IAQ standards that are widely adopted, covering ventilation rates and air filtration. Older buildings may not have been designed to meet these standards, resulting in subpar IAQ.

Older buildings often fail to meet these standards due to outdated infrastructure and lack of modern air filtration systems, which can result in regulatory fines and increased health risks for occupants. Additionally, many of these buildings were constructed before current IAQ standards were established, making retrofitting necessary but often challenging and costly.
