It’s a shift that starts with data. Lerczak explained that energy audits are increasingly the norm, helping stakeholders set baselines and build actionable decarbonization roadmaps. The goal: ensure that improvements aren’t just one-off wins but part of a coordinated push toward lower emissions and higher efficiency. “Contractors who understand how their work fits into these bigger strategies are more valuable to owners than ever,” he added.

Perhaps the most striking finding in this year’s SSI report is the widespread adoption of building automation systems (BAS). Ninety-four percent of surveyed venues now use BAS to control HVAC systems. “Despite seeing an 84% decrease in resource consumption, only 38% reported decreased operating costs as a benefit of their sustainability program,” Lerczak noted. The paradox? While the technology is there, many venues may not be fully optimizing these platforms to capture all the savings. “It’s not just about installing controls – it’s about optimizing them, especially in venues that operate year-round for sports, concerts, and conventions. Contractors can add real value by ensuring systems are tuned for both peak and partial occupancy.”

Lighting controls are also catching on. Thirty-two percent of venues have installed sensors throughout their entire facility, with 90% of those reporting improved facility management and 65% crediting sustainability programs for increased sponsorship revenue. Water efficiency, though lagging behind, is beginning to see adoption, with 14% of venues using sensors to detect leaks in restrooms – a small step with outsized potential for resource savings.

Retrofitting older stadiums for sustainability remains a challenge. Upfront costs, competing priorities, and timing all play a role, especially when investments in fan-facing experiences often take precedence. Yet, teams are reframing the conversation: Reduced operating costs, improved comfort, and longer equipment life are now seen as essential value propositions, not just nice-to-haves. Increasingly, upgrades are being bundled with planned renovations to minimize disruption and maximize impact. Lerczak said, “We’re seeing more MEP upgrades bundled with planned renovations to minimize disruption and maximize value. For contractors, it’s critical to coordinate with these broader capital projects and understand the owner’s full vision.”

For sheet metal and HVAC contractors, the evolution of sports venues into year-round, multi-use facilities means system flexibility is paramount. “Owners are asking how HVAC and air handling systems can adapt to off-season events, partial occupancy, and changing climate demands,” Lerczak said. “Contractors should be asking about controls integration, lifecycle value versus first cost, and how their work supports certifications like LEED or ENERGY STAR.”

He advised, “Don’t just focus on price. Ask about utility incentives, roles and responsibilities for sustainability strategy, and how your systems will be verified and maintained long-term. The venues that get this right – like those hosting the Super Bowl or the Bears’ future year-round home – set a new standard for the industry.”

The business case is finally catching up with the environmental one. Fifty-eight percent of venues surveyed saw increased sponsorship revenue tied to sustainability programs, while 39% lowered operating costs. Among those with advanced lighting controls, most cited improvements in both facility management and visitor satisfaction. For HVAC systems, nearly all venues with comprehensive controls reported better management and resource consumption, although the link to direct cost savings is less clear – another sign that optimization, not just installation, is where the next gains will be found.

“Contractors who can demonstrate the lifecycle value of their solutions, rather than just the lowest upfront cost, are winning these jobs,” Lerczak said.

So what’s next? “Prioritizing all-electric and decarbonization strategies, enabling real-time monitoring and commissioning, transitioning to low global warming potential refrigerants, and leveraging data-driven automation,” Lerczak said. The evolving regulatory landscape is another wildcard, with updates to EPA refrigerant rules and new local energy codes pushing venues further down the sustainability path.

He also pointed to the importance of ongoing teamwork: “Sustainability-driven efforts do not happen in a silo. Successful outcomes depend on early and ongoing coordination among owners, designers, contractors, operators, and vendors. When sustainability is baked in from the start, projects are more likely to deliver measurable cost savings, operational reliability, regulatory readiness, and long-term value.”
