How to Balance Sustainable Facilities Management with Cost Initiatives

There is a persistent misconception in facilities management that sustainability is a separate effort. Something layered onto operations. Something that competes with cost.

In reality, sustainability is what efficient operations look like when they are executed well.

• Buildings that use less energy cost less to run.
• Equipment that is maintained properly lasts longer and fails less often.
• Spaces that are used efficiently require fewer resources to support.

Across every major area of facility performance, the sustainable decision and the cost-effective decision are increasingly the same decision.

In this video, Nuvolo’s Paul Head shares how organizations can “use green to be green” by leveraging sustainability goals to enhance financial performance across their facilities.

Energy waste, reactive maintenance, and underutilized space all create the same problem:

• Higher operating costs
• Higher environmental impact

That overlap is where the opportunity sits.

According to the International Energy Agency, buildings account for roughly 30% of global energy consumption. In commercial environments, energy is also one of the largest controllable operating expenses.

That means reducing energy use is not just a sustainability initiative. It is one of the most direct ways to improve financial performance.

In addition to this, research from the World Economic Forum and PwC found that targeted interventions can reduce building energy intensity by up to 38%.

For facilities teams focused on both sustainability and cost reduction goals, the research shows that a focus on energy efficiency can have transformative results for both.

Why Making Energy Waste Visible is Critical

Energy is often where sustainability conversations begin because it is where inefficiency is easiest to quantify.

Smart building systems have made it possible to:

• Adjust HVAC based on real occupancy
• Automate lighting to match usage patterns
• Continuously monitor performance in real time

In many commercial environments, these types of improvements can reduce energy consumption by 20–25%.

But the real shift is not automation alone because automation cannot occur without first understanding how these systems and spaces are performing. Having visibility into energy data, building usage, and asset performance is how teams can continuously optimize performance. This is where sustainability starts to move from a project to an operating model.

How Preventive Maintenance Is an Efficiency Strategy

One of the most overlooked sustainability levers is maintenance strategy. Equipment that is poorly maintained does not just fail more often. It operates less efficiently every day it runs.

The U.S. Department of Energy estimates that preventive maintenance can reduce costs by 12–18% compared to reactive programs, while industry studies show reactive maintenance can cost several times more — often ranging from 3 to 9 times higher depending on the environment.

That difference compounds quickly across a portfolio.

Every reactive repair introduces:

• Emergency labor costs
• Expedited parts procurement
• Extended downtime

Every preventive maintenance activity does the opposite:

• Stabilizes performance
• Reduces energy waste
• Extends asset life

Efficient assets do more than reduce energy use. They reduce the need for constant intervention. Fewer maintenance calls translate to fewer technician dispatches, less travel, and lower emissions across the service lifecycle. At the same time, reduced failure rates limit replacement cycles and material waste, creating a more predictable and sustainable operating model.

Preventive maintenance is not just about reliability. It is one of the most consistent ways to improve both cost and sustainability outcomes at the same time.

Using Space Utilization Data to Eliminate Waste

Not all inefficiency is mechanical. Some of it is spatial.

Underutilized space is one of the most overlooked drivers of both cost and environmental impact. Heating, cooling, lighting, and maintaining space that is rarely used creates a constant drain on resources.

According to JLL, 62% of corporate real estate decision-makers say they need to improve how they utilize their buildings, but most lack the tools, skills, and data to do so.

When occupancy data is disconnected or underutilized:

• Buildings operate at full capacity regardless of actual demand
• Energy is consumed in empty or underused areas
• Real estate costs remain fixed despite changing workplace behavior

When utilization is understood and acted on:

• Space can be consolidated or reconfigured
• Energy usage can be aligned to real occupancy
• Portfolios can be right-sized to reduce unnecessary spend

Every square foot that is no longer needed is energy that no longer needs to be consumed. But the impact goes further than energy alone.

Underutilized space still requires cleaning, maintenance, and daily operational support. It drives unnecessary janitorial services, excess waste collection, and water usage for restrooms, kitchens, and cleaning processes that are not tied to actual demand. Lighting, HVAC, and building systems continue to run whether the space is occupied or not.

When space is aligned to real usage, those inefficiencies start to disappear. Fewer areas to service means fewer cleaning routes, less water consumption, reduced waste, and lower energy demand across the board. It also allows teams to focus resources where they are actually needed, improving both operational efficiency and sustainability outcomes at the same time.

Green Building Certification: Where Sustainability Drives Asset Value

For facilities and real estate leaders, sustainability is no longer just an operational goal. It is a clear driver of asset value.

LEED-certified buildings consistently outperform non-certified peers. Analysis from CBRE shows rent premiums of 4–8%, while research from the U.S. Green Building Council found sales premiums exceeding 25% in urban markets.

These gains are not driven by certification alone. They reflect stronger operational performance.

LEED-certified buildings also report lower operating costs, with studies showing an average reduction of 10.1%. At the same time, they tend to lease faster, maintain higher occupancy, and attract tenants who increasingly prioritize sustainable workplaces.

The takeaway is straightforward.

Sustainability is not just reducing environmental impact. It is improving how buildings perform financially.

For facilities teams, certification is not the starting point. It is the result of consistent, efficient operations across energy, maintenance, and space.

Five Actions to Align Sustainable FM Goals with Cost Outcomes

1. Audit your energy baseline. You cannot reduce what you cannot measure. A systematic energy audit — starting with HVAC, lighting, and refrigeration — identifies where the largest waste streams exist. Many utilities offer free or subsidized audits. Smart sub-metering can be deployed incrementally, starting with the highest-consumption systems in your facilities portfolio.
2. Shift to preventive maintenance on critical assets. Start with your top ten highest-impact assets. A structured preventive maintenance program on HVAC, elevators, and building systems will meaningfully reduce both energy waste and emergency repair costs — a core pillar of any sustainable facilities management strategy.
3. Digitize your asset register with an IWMS. Effective sustainability and cost control both require visibility across the asset lifecycle. Digital asset management through an Integrated Workplace Management System (IWMS) enables FM teams to forecast repairs, optimize replacement timing, and identify equipment consistently underperforming on energy efficiency. Without this visibility, decisions default to reactive — which means paying more for worse outcomes.
4. Invest in smart controls and automation. Occupancy-based HVAC and lighting automation, building management systems, and IoT-enabled monitoring are now sufficiently mature to deliver measurable ROI in most commercial settings. AI-enhanced energy management tools can continuously optimize operations in ways that manual oversight cannot sustain — and directly support ESG reporting requirements.
5. Track toward green certification — even before you certify. Using LEED, BREEAM, or equivalent frameworks as internal benchmarks focuses improvement efforts on the dimensions that drive the greatest financial and environmental value. The certification itself unlocks market premiums; the process of working toward it improves the asset regardless.

The Role of an IWMS

Sustainability efforts often struggle because the data behind them is fragmented.

Energy, maintenance, space, and asset data are managed in separate systems. That creates gaps in visibility and slows decision-making.

An Integrated Workplace Management System (IWMS) connects these areas into a single operational layer.

Instead of managing sustainability as a standalone effort, teams can:

• Align maintenance with energy performance
• Connect asset data to capital planning decisions
• Optimize space to reduce unnecessary energy use
• Support energy and waste reporting with consistent, reliable data

At Nuvolo, this is the foundation of how we help facilities teams operate.

As part of Trane Technologies, there is a shared focus on turning sustainability commitments into measurable outcomes. Initiatives like the Gigaton Challenge, which aims to reduce one gigaton of carbon emissions from customer footprints by 2030, reflect that scale.

But goals like that are not achieved through one-time projects. They are achieved through daily operations.

As Stephen Zetarski, President of Nuvolo, has written:

“Decarbonizing the built environment can’t be accomplished through equipment upgrades alone. It also requires continuous operational intelligence that can coordinate maintenance, energy, space and asset performance in real time.”
