October is the quietest month for your building. It's also the most revealing.

In the middle of summer, your building is fighting to stay cool. In the depths of winter, it's straining to stay warm. In both seasons, your systems are running so hard that real problems hide behind sheer output.

Then comes October. The moderate temperatures of fall create something valuable: a diagnostic window. When your building isn't battling extreme heat or cold, its systems reveal how they actually behave under normal load. And that's when the hidden issues surface.

This is when we find the control sequences that never quite settle. The scheduling gaps that waste energy overnight and on weekends. The overrides an operator set months ago and never reversed. The equipment that's been quietly compensating for a problem no one diagnosed.

During peak seasons, these issues get masked by systems running flat out. In October, they stand out clearly, which makes them far easier to identify and correct.

Here's why the timing matters: whatever you fix now, you fix before winter stresses your building all over again. Correcting a control issue in October means a more comfortable, more efficient building in January, instead of a season of tenant complaints and inflated energy bills.

The calm season isn't downtime. It's your best chance to get ahead of the problems winter will only amplify.

Curious what your building is doing when it isn't under pressure? That's exactly what our retro-commissioning process is built to uncover.

ENERGY STAR Expertise You Can Count On

ENERGY STAR certification is more than a score. It’s an opportunity to understand building performance, recognize opportunities for improvement and make informed decisions about what comes next.

With 14 years of experience as an ENERGY STAR Licensed Professional, Global Facility Solutions President Robert Calloway helps building owners navigate the certification process and make sense of their energy performance data.

That expertise extends across our team. From understanding ENERGY STAR Portfolio Manager and evaluating eligibility to navigating certification requirements and identifying opportunities to improve performance, we understand the details that can make a difference.

We help building owners move beyond benchmarking to turn data into action—with the clarity and confidence to make informed decisions about their buildings.

Have questions about ENERGY STAR certification? GFS is here to help.

The buildings that will struggle with BEPS aren't the old ones. They're the ones still sitting on their studies.

Here's what we've learned working with building owners across multiple compliance cycles: the age of your building matters far less than what you do after the analysis lands on your desk.

We see it constantly. An owner commissions a study. We deliver clear recommendations, a realistic roadmap, and a path to compliance. And then... nothing. The report goes in a drawer. The plan waits for "next year." Meanwhile, the deadlines keep moving closer.

The buildings that will struggle aren't the aging ones with outdated systems. Those have a clear path forward. The ones that will struggle are the ones whose owners have a plan and aren't acting on it.

Here's why this matters right now: these projects take time. Electrification, HVAC upgrades, control system modernization, none of it happens overnight. It takes time to scope, fund, implement, and see results. The owners who start now have room to spread the work across budget years and hit their targets. The ones who wait compress their timeline until compliance becomes a crisis.

And if you're a BGE customer, waiting costs you even more. The Building Performance Tune-up Program is still offsetting up to 85% of project costs.

As you finalize your 2027 budget, here's the question worth asking: is your compliance plan a line item, or is it still sitting on a shelf?

The study was the easy part. Let's talk about what comes next.

Most engineering firms hand you a report and walk away. We stay until the job is done.

That approach is at the heart of how we’ve expanded Global Facility Solutions’ services.

Building owners today are navigating BEPS mandates, corporate decarbonization goals, tenant expectations and investor pressure—all at once. Yet the support they need is often fragmented: one firm conducts the audit, another handles the design, a contractor completes the work, and someone else verifies the results.

Every handoff creates an opportunity for the plan to lose momentum.

We’ve expanded our services to help close those gaps—connecting engineering, planning and implementation so building owners can move from recommendations to results without having to manage the patchwork themselves.

Now, GFS can support your building from the first question to final commissioning—and beyond:

Start with sustainability analysis and BEPS support to see exactly where your building stands. It's a low-cost, low-risk first step.

Move into energy and MEP engineering when you need to cut emissions and improve your Energy Utilization Index, backed by real building analysis and energy audits.

Tackle major projects like building electrification, HVAC upgrades, central boiler and chiller plants, and control system modernization.

Put your plan into action with implementation support—not just onto a shelf.

Keep GFS by your side through construction, startup, and commissioning, so what was designed is what actually gets delivered.

One partner. One accountable team. The full life of your project. Where does your building stand today? That's where we start.

Fall brings the biggest occupancy shift of the year. Summer schedules are over, schools are back in session, and offices are running at full capacity again.

Here's what many building owners miss: if your occupancy changed but your ENERGY STAR Portfolio Manager profile didn't, your score is about to tell the wrong story.

When more people return to your building, energy usage naturally increases. Your utility provider is pushing that higher usage data into Portfolio Manager automatically. But if your headcount, operating hours, and property use details still reflect summer operations, the system sees rising consumption with no explanation—and your score drops.

That's not an efficiency problem. That's a data problem.

Take 30 minutes to review:
● Worker headcount—does it reflect actual fall occupancy?
● Operating hours—have schedules shifted with the season?
● Property use details—any changes in how spaces are being used?

Accurate metrics now mean your year-end data tells the true story of your building's performance—which matters for your ENERGY STAR score, your BEPS compliance position, and every benchmarking submission built on this year's data.

Not sure your profile reflects reality? GFS can review your Portfolio Manager setup and ensure your data is working for you, not against you.

𝗕𝘂𝗱𝗴𝗲𝘁 𝘀𝗲𝗮𝘀𝗼𝗻 𝗶𝘀 𝗵𝗲𝗿𝗲. As you plan for 2027, energy compliance and building performance deserve a line item—not an afterthought.

Here's what we're seeing: the building owners who lock in their compliance services now are the ones who avoid the spring scramble. We're already fielding calls from clients who want their third-party verification scheduled the moment their December bills arrive.

As you build your 2027 budget, consider:

𝗧𝗵𝗶𝗿𝗱-𝗽𝗮𝗿𝘁𝘆 𝗱𝗮𝘁𝗮 𝘃𝗲𝗿𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻. If your building is subject to Maryland BEPS, verification isn't optional—and demand for qualified verifiers peaks close to deadlines. Budgeting and booking now means you're first in line, not waiting in one.

𝗘𝗻𝗲𝗿𝗴𝘆 𝗮𝘂𝗱𝗶𝘁𝘀 𝗮𝗻𝗱 𝗮𝘀𝘀𝗲𝘀𝘀𝗺𝗲𝗻𝘁𝘀. If your BEPS study identified energy conservation measures, 2027 should be the year you start implementing—not the year the recommendations sit on a shelf. Spreading projects across multiple budget years starts with putting the first phase in this budget.

𝗨𝘁𝗶𝗹𝗶𝘁𝘆 𝗶𝗻𝗰𝗲𝗻𝘁𝗶𝘃𝗲 𝗽𝗿𝗼𝗴𝗿𝗮𝗺𝘀. BGE's Building Performance Tune-up Program is still offsetting up to 85% of costs. Incentive programs don't last forever—build participation into your plan while the funding is strong.

𝗕𝗲𝗻𝗰𝗵𝗺𝗮𝗿𝗸𝗶𝗻𝗴 𝘀𝘂𝗽𝗽𝗼𝗿𝘁. If tenant utility data collection slowed your submission this year, budget for a process that starts in January, not May.

The gap between buildings that hit their compliance and performance goals and those that don't usually comes down to one thing: planning ahead.

Let's talk about what your building needs in 2027—so it's in the budget before the budget is final.

This Labor Day, GFS recognizes the people whose work keeps buildings running.

The engineers who diagnose problems others can't see. The building operators who make rounds at 6 a.m. to check systems before tenants arrive. The technicians who climb into mechanical rooms and above ceilings to keep equipment performing. The maintenance teams whose steady, often invisible work prevents the failures no one ever hears about.

Our industry runs on this kind of expertise: hands-on, practical, and earned over years in the field. It's the foundation of everything we do at GFS, and it's what makes better building performance possible.

To everyone whose work keeps the built environment operating: thank you.

Our offices will be closed Monday, September 7th in observance of Labor Day. We hope you enjoy a well-deserved break with family and friends.

We're excited to announce two additions to the GFS team!

David Hirschauer joins us as Vice President—and for David, this is a homecoming. He was part of the GFS team 12 years ago, and we're thrilled to welcome him back. In the years since, David has grown tremendously, earning his MBA and building deep experience in the energy industry, including time at Constellation Energy. He returns knowing our business, our approach, and many of our long-standing clients. Some reunions are just meant to happen.

Clayton Garmon joins our engineering team, bringing a passion for both design and sustainability. Clayton found GFS while relocating to Maryland and connected immediately with our mission and approach to solving building challenges. He'll be jumping into MEP design and sustainability and energy solutions work for our clients.

What we love about both of these stories: David returns because the relationships never ended, and Clayton sought us out because our message resonated. That says something about the culture we've built together.

Please join us in welcoming David and Clayton to the team!

Interested in joining a growing team that's helping buildings across the country operate more efficiently and sustainably? We're always looking for talented engineers. Visit our website to learn more.

As summer winds down, the window for one of the most valuable building performance investments is opening: fall retro-commissioning.

Transitional seasons (when buildings shift from cooling to heating mode) reveal system inefficiencies that are invisible during peak summer or winter operation. This is when we consistently find the most impactful opportunities for improvement.

Here's why fall is the ideal commissioning season:

Seasonal transitions expose control system issues. As outdoor temperatures fluctuate, buildings that rely on overridden or poorly programmed controls struggle to maintain comfort efficiently. These are exactly the issues that drive up energy costs and tenant complaints throughout the winter.

Utility rebate programs have funding available now. BGE and other utility providers typically have program capacity in the fall. Taking advantage of incentives before year-end maximizes your return on commissioning investment.

Results are visible before year-end compliance submissions. Issues identified and corrected in September and October show up in your 2026 annual energy data—improving your ENERGY STAR score and BEPS compliance position before the year closes out.

Planning now means implementation in September. Retro-commissioning projects require scheduling, scoping, and coordination. Building owners who start the conversation in August are positioned to have work completed before the heating season is in full swing.

Don't wait until you're dealing with winter comfort complaints to address building system performance. The best time to find and fix inefficiencies is before they become problems.

Contact GFS to schedule your fall retro-commissioning assessment.
