From the very first moment we met GACS-2026 One thing stood out when we went public: there's a huge amount of noise in the market. Everyone senses something is coming (EPBD, Bbl, energy management, demonstrability), but in practice, the question remains:
“What is really mandatory… and how do I prove it?”
Where it started: regulations → practice
The start of GACS-2026 didn't come from a product, but from a problem we saw everywhere:
many buildings have parts of automation (BMS, control cabinets, clock programs, meters), but not one coherent system that:
✅ demonstrably meets the requirements
✅ is legally defensible
✅ and most importantly: actually focuses on energy performance
That's why we started translating laws and regulations into something that building owners, installers, and managers can apply. Not as thick theoretical reports, but as practical steps, choices, and evidence.
The first gear: whitepaper & knowledge sharing
When we shared our white paper, we saw just how great the need is. Not just likes, but especially questions, DMs, and conversations with industry players. Because GACS isn't just about "putting something up." GACS is:
-
interpreting scope and capacity (what is/is not included)
-
technical analysis of installations and controls
-
proportionality and feasibility (what is logical and defensible)
-
and then: record, secure and improve
From opinion to method: the 6 steps
To structure this confusion, we've built our approach around a clear methodology. The basic approach is always this:
-
Determine scope & obligation
Capacity, building function, generation, situation in the building. -
GACS 360 Analysis (baseline measurement)
What is there, what works, what is missing, where are the greatest energy opportunities? -
Report & Action Plan
Not “pretty texts”, but: concrete measures, priority, impact, investment and order. -
Compliance file (demonstrability)
This is where things go wrong for many buildings. You can have a lot of things in order technically, but without a file, you're left empty-handed.
We build a file that is logical, traceable and defensible. -
Monitoring & dashboarding
Because without measurement, GACS is a paper tiger. Energy and performance data must be visible. -
Optimization + periodic reporting
This is where the real value lies: continuously adjusting, signalling, improving and demonstrating what you have achieved.
The evidence from practice: 73 analyses Municipality of The Hague
The approach only really became clear through practical pressure. With, among other things, the trajectory of 73 GACS 360 analyses (Municipality of The Hague) we received the same questions dozens of times in a short period of time:
-
Where is the line between “GBS present” and “GACS compliant”?
-
What is the minimum required to demonstrably comply?
-
Which measures are proportionate in existing buildings?
-
How do you organize this without the project getting stuck?
It is precisely there that our role arose as brand-independent knowledge and implementation partner:
We connect legislation, technology and realistic implementation.
The next step: measuring, sensors and smart unlocking (even without demolition work)
In existing buildings, cabling is often the biggest obstacle. That's why we take a pragmatic look at implementation options such as LoRaWAN sensors and smart connections (Modbus/BACnet) to make data available quickly and affordably.
Think about:
📌 energy meters (electrical/thermal)
📌 room temperature, CO₂, RH, presence
📌 fault messages, operating hours, setpoints, valve positions
📌 performance indicators per installation (component)
Not to have “more data”, but to steering to make possible.
And then: monitoring & reporting (where it all comes together)
For us, monitoring isn't just a screenshot of a dashboard. It's a rhythm:
-
monthly/quarterly reporting with trends and deviations
-
reporting waste and incorrectly configured regulations
-
justification of measures (what will it yield)
-
evidence for owner, user and auditor/supervisor
-
and a continuous improvement cycle
💡 That's why we often say:
GACS isn't an expense. It's an investment that pays for itself—and you can demonstrate it.
Where we're going
We're building a network where building owners, installers, and knowledge partners can share the same story. Because the challenge is too big to tackle alone—and because the impact (energy, grid congestion, comfort, costs) is too significant.
Do you want to know where your building is located and which step makes sense now?
Send us a message and we'll start with a scope + a clear baseline measurement.
GACS-2026 is the brand-independent knowledge partner/advisor for all GACS issues.
