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.

Picture walking into an office on a hot summer day, where the air is refreshingly cool, or entering a cozy, warm home on a chilly winter evening—have you ever wondered how much energy it takes to maintain that comfort year-round?

This climate-controlled comfort is brought to you by HVAC (Heating, Ventilation, and Air Conditioning) systems, which are indispensable for indoor environments. However, this convenience comes at a substantial cost: HVAC systems are among the largest consumers of energy in North America. HVAC operations represent a considerable portion of total energy consumption, making them central to discussions about sustainability and environmental impact.

Understanding the scope of this energy use and the underlying factors is key to addressing one of the most critical challenges facing the energy sector today.

HVAC Energy Consumption: The Scope of the Problem

In North America, HVAC systems are a significant contributor to energy consumption. According to the U.S. Department of Energy (DOE), HVAC systems account for around 40% of the energy used in commercial and residential buildings, which places a substantial burden on energy resources. HVAC systems account for approximately 35% of total energy consumption in U.S. commercial buildings, and around 45% in residential buildings, primarily due to heating, cooling, and ventilation demands. In Canada, this figure tends to be higher because of more extreme temperature variations, particularly during the winter months (EIA Energy).

Breakdown of energy consumption in a typical building. Over 50% of energy consumption is related to HVAC systems.

This energy consumption not only leads to escalating operational costs but also exacerbates carbon emissions. Most of the energy powering HVAC systems is derived from fossil fuels, creating a double-edged sword: while these systems make indoor spaces more livable, they also significantly contribute to greenhouse gas emissions. If HVAC energy usage continues on this trajectory, it will hinder efforts to meet global climate targets.

Why Is HVAC Energy Consumption So High?

1. Aging Infrastructure

A substantial portion of North America’s building stock is decades old, and many of these structures have outdated HVAC systems. These legacy systems were designed at a time when energy efficiency standards were far less rigorous, leading to inefficient heating, cooling, and ventilation.

According to the U.S. Environmental Protection Agency (EPA), HVAC systems in buildings older than 20 years use 20-30% more energy to operate than those in modern buildings equipped with energy-efficient systems. The cost of replacing or retrofitting these systems can seem prohibitive, leading to a cycle of inefficiency as property owners defer necessary upgrades.

2. Slow Pace of Innovation

Despite significant advancements in other areas of building technology, the HVAC industry has been slow to adopt cutting-edge innovations. Technologies like smart HVAC systems, smart thermostats, and energy recovery ventilators (ERVs) can significantly reduce energy consumption, but their adoption has been sluggish. Many commercial and residential properties still operate with older systems that don’t leverage real-time data or optimize energy usage based on demand.

The lack of integration between HVAC systems and broader building management systems further limits opportunities for energy savings. This stagnation in the industry has left buildings operating at inefficient levels, unable to keep up with modern sustainability standards.

3. Climate and Seasonal Extremes

The geographic diversity of North America means that HVAC systems must cope with a wide range of climate extremes. The International Energy Agency (IEA) has noted a significant rise in air conditioning demand, driven by more frequent heatwaves in the southern U.S. and globally. Over the past decade, cooling-related energy consumption has increased by about 10%, with further growth expected as temperatures continue to rise. This surge in demand is a major contributor to overall electricity use in buildings, and without improved efficiency measures, cooling is projected to increase by 50% by 2030.

In contrast, the northern regions, particularly in Canada, experience long, harsh winters that place enormous demand on heating systems. Seasonal temperature extremes, combined with an aging infrastructure, push HVAC systems to their limits, leading to excessive energy consumption.

4. Poor Building Design and Insulation

Inefficient building designs contribute significantly to the high energy consumption of HVAC systems. Many older buildings lack the insulation, energy-efficient windows, and other design features necessary to reduce the workload on HVAC systems. Studies show that buildings with poor insulation can increase HVAC energy usage by as much as 30%.

This inefficiency creates a continuous cycle of energy waste, as HVAC systems must work harder to maintain comfortable indoor temperatures, particularly during seasonal extremes.

Causes of High Energy Consumption in HVAC Systems

1. Inefficient Building Designs

Many buildings in North America were constructed long before energy-efficient architectural principles became a priority. Poorly insulated walls, outdated windows, and inadequate building envelopes force HVAC systems to work overtime, increasing energy usage unnecessarily.

According to the EPA, improving building insulation alone could save an average of 15% on heating and cooling costs, demonstrating the outsized impact that small design improvements can have on overall energy use. This is achieved by reducing heat transfer, allowing HVAC systems to operate more efficiently. Insulating key areas such as attics, floors, and walls can significantly reduce the workload on heating and cooling systems, ultimately lowering energy bills and improving comfort.

2. Non-Integrated HVAC Systems

A significant amount of energy is wasted when HVAC systems operate in isolation, without integrating into a building's broader energy management infrastructure. When systems run independently, they cannot make real-time adjustments based on occupancy, outdoor temperature, or energy price fluctuations. This lack of integration leaves buildings operating inefficiently, with energy savings that could be realized through smarter coordination between systems left untapped.

3. Infrequent Maintenance

Regular maintenance is essential for ensuring that HVAC systems run at peak efficiency. However, many systems are neglected, with clogged filters, dirty ducts, or malfunctioning parts leading to energy waste. According to sources such as ENERGY STAR and Mitsubishi Electric, a poorly maintained HVAC system can consume 10-25% more energy than a well-maintained one. This increased energy consumption is primarily due to the system working harder to achieve the same level of temperature control, often caused by factors like clogged filters, unclean coils, or refrigerant leaks. By regularly maintaining your HVAC system, such as cleaning filters and coils, and checking for leaks, you can ensure its efficient operation, ultimately saving energy and reducing costs

Solutions for Reducing HVAC Energy Consumption

1. Smart HVAC Systems

One of the most promising methods of reducing HVAC energy consumption is the integration of smart systems. These systems use sensors, data analytics, and AI to monitor real-time building conditions, adjusting heating, cooling, and ventilation based on actual demand. This approach helps avoid energy waste while maintaining comfort.

Smart thermostats and smart HVAC systems have been shown to reduce energy consumption by as much as 35%, as per the American Council for an Energy-Efficient Economy (ACEEE). These technologies optimize energy use by adjusting temperature settings based on occupancy patterns and external weather conditions, significantly minimizing air conditioner runtime. Additionally, these systems can learn the daily routines of occupants, allowing for dynamic and efficient temperature control without sacrificing comfort.

2. Energy Recovery Ventilation (ERV) Systems

Energy Recovery Ventilation (ERV) systems are a key innovation in reducing HVAC energy consumption. They work by transferring both heat and moisture between outgoing and incoming air streams, allowing them to recover up to 70-80% of the energy that would otherwise be lost during ventilation. This process reduces the load on HVAC systems, leading to substantial energy savings by preconditioning the fresh air, thus minimizing the need for additional heating or cooling.

3. Low-Pressure Filtration Systems

Low-pressure filtration systems are an often-overlooked solution for improving HVAC efficiency. Traditional air filters can create a pressure drop in HVAC systems, forcing fans and motors to work harder and use more energy. Low-pressure filters, on the other hand, maintain high air quality standards while reducing the energy needed to circulate air throughout a building.

Low-pressure filtration can allow HVAC systems to operate more efficiently, contributing to HVAC energy savings of an average of 15%. This technology not only saves energy but also enhances indoor air quality, making it a win-win solution for energy efficiency and occupant health.

4. Retrofitting and Building Modernization

Retrofitting older buildings with modern, energy-efficient systems offers enormous potential for energy savings. Simple measures, such as installing energy-efficient windows, adding insulation, or upgrading HVAC systems to more efficient models, can significantly reduce energy consumption.

A study by the U.S. Department of Energy (DOE) indicates that retrofitting older buildings can result in energy savings of 20-30%. One key technology that plays a significant role in these savings is Variable Refrigerant Flow (VRF) systems, which offer precise control of heating and cooling across different zones within a building. VRF systems are particularly beneficial for large, multi-zone buildings, where they can achieve energy savings of up to 42% compared to traditional HVAC systems by optimizing the distribution of refrigerant to specific areas based on demand.

5. Routine Maintenance and Monitoring

Regular HVAC maintenance plays a crucial role in ensuring system efficiency and reducing energy consumption. Essential tasks like replacing filters, cleaning coils, and checking refrigerant levels can prevent small issues from escalating into major energy drains. Studies show that a well-maintained HVAC system can reduce energy consumption by 10-20% over its lifespan. Additionally, integrating HVAC systems into a building's energy management platform allows for real-time monitoring and adjustments, further optimizing energy use.

The Future of HVAC: A Move Towards Sustainability

The HVAC industry is at a critical juncture, as regulatory pressures and technological innovations are reshaping its future. Governments across North America are tightening energy efficiency standards, with both Canada’s Energy Efficiency Regulations and the U.S. DOE’s energy conservation standards for HVAC systems becoming more stringent. This is pushing the industry toward adopting more sustainable practices.

A major focus for the future of HVAC is the decarbonization of systems, with a shift away from fossil fuel-based heating and cooling. Innovations such as heat pumps, which transfer heat more efficiently and use less energy, are gaining popularity. Heat pumps can reduce energy consumption by up to 50%, making them a highly attractive option for both residential and commercial applications.

In addition to heat pumps, the use of renewable energy sources, such as solar-powered HVAC systems, is set to become more widespread. Solar-assisted cooling and heating systems offer the potential to dramatically cut the sector’s reliance on non-renewable energy sources, further reducing its carbon footprint.

The HVAC industry is a major energy consumer, accounting for a significant share of North America's total energy use. Factors such as aging infrastructure, inefficient building designs, and a slow pace of innovation have kept energy consumption high. However, there is hope on the horizon, as emerging technologies and stricter regulations are driving the industry toward a more sustainable future.

By adopting smart systems, low-pressure filtration, and energy-efficient building practices, property owners can reduce HVAC energy consumption, cut costs, and contribute to a cleaner, more sustainable environment. The HVAC industry must embrace innovation and modernization to meet the growing demand for energy-efficient, sustainable solutions—creating a future where indoor comfort and environmental responsibility go hand in hand.
