ENERGY THAT WORKS FOR YOU
Every solution adds value.
Together, they work better.
From a targeted intervention to a complete upgrade, we start with the actual needs of your building.
KNX & smart buildings
Coordinated control of lighting, shading and climate using KNX, with BMS integration where supported.
Explore the solution
External wall insulation
External insulation and heat-loss reduction, with careful attention to building details.
Explore the solution
Heat pumps & fan coils
Heating and cooling with a correctly sized heat pump and fan coil units (FCU).
Explore the solution
Integrated energy upgrades
Envelope, generation, heating, cooling and automation in one coordinated plan.

Beyond choosing equipment.
We design the outcome.
A building is a system. Its envelope, installations and usage are connected. We assess your investment as a whole.

HOW WE WORK
From the first conversation
to reliable operation.
Assessment
Energy bills, requirements and technical information, with a site visit where needed.
Proposal & scenarios
Interventions, budget and explicit savings, ROI and payback assumptions.
Design
System sizing, coordination and assessment of required approvals.
Installation
Planned implementation with checks at critical stages.
Commissioning
Testing, adjustments, documentation and user guidance.
Monitoring & support
Operating checks and support under the agreed plan.
WHY GEBS
Technical thinking.
A clear investment picture.
The building before the product
Solutions selected around loads, use, opportunities and constraints.
Transparent assumptions
Understand the scope of the proposal and how each financial scenario is calculated.
Owner control
Documentation, instructions and system files that support independent maintenance.
APPLICATIONS
Different buildings.
Specific needs.
Homes & apartment buildings
Room-level comfort, reduced losses and use of roof space. Assessment of communal installations and required consents.
Offices & commercial spaces
Schedules, occupancy and work-related loads. Smart lighting and climate control with operating efficiency in mind.
Larger buildings & hospitality
Multiple zones, demanding use and central supervision. Staged interventions and BMS integration.
ENVIRONMENTAL PERFORMANCE
Less waste.
More responsible operation.
Environmental improvement starts with lower energy demand. We combine efficient equipment, renewable energy and consumption control.
Energy and emissions indicators need a defined reference period, data and appropriate factors. We do not publish unsupported percentages or zero-footprint claims.

Your questions, in practice.
Which intervention should come first?
It depends on the building. We assess consumption, envelope and systems before prioritising interventions. The right sequence can avoid oversized equipment and unnecessary costs.
When does a solar battery make sense?
When the generation and consumption profiles, energy prices and storage costs support it. A battery is not automatically the most economic option for every building.
What does zero-feed-in mean?
Controlled operation intended to prevent energy export to the grid. Suitability, technical requirements and connection conditions are assessed for each installation.
Can KNX be installed in an existing building?
We assess cabling, access, devices and the scope of work. A solution may combine different communication media once compatibility has been confirmed.
Can a heat pump also provide cooling?
Yes, within a suitably designed system. FCU systems need provision for condensate drainage, insulation, hydraulic distribution and appropriate controls.
How many years will payback take?
We do not promise a universal period. Payback is assessed using net investment and annual net savings, with explicit assumptions and alternative scenarios.
Is the preliminary assessment an energy study or certificate?
No. It is an initial information-gathering step. Technical design, a site visit and any energy certificate have a separate agreed scope.
LET’S START WITH YOUR BUILDING
Take the first step
with actual data.
Describe your property and your needs. Prepare a summary for a preliminary energy assessment.
This form prepares your request. Your information stays on your device until you export it or choose to send it by email. Nothing is submitted automatically.
Explore a payback scenario
Enter your own assumptions. This calculation does not predict the performance of a particular installation.
Simple payback = investment / (gross savings − additional costs). Constant annual values; excludes discounting, financing, tax, degradation and replacements.
