The next frontier for energy in real estate
Your buildings and your energy buying, run as one system across the whole portfolio. For commercial and residential real estate.
The next edge is fusing technical and financial optimisation
Efficient buildings
Smart buildings cut waste and kept tenants comfortable.
Dynamic buying
Fixed prices carry an ever bigger risk premium. A mix of market prices and long-term green power contracts avoids it and makes the portfolio renewable.
Fusing both
Buildings and energy buying run as one system, across the whole portfolio.
See first. Steer second.
A financial digital twin of your portfolio
Cost per building, per quarter hour
And why: contracts, green power, market prices and tenant consumption in one view.
Smarter energy buying
See how far you can hedge beyond PPAs and spot price exposure.
Reporting and invoice checks on autopilot
No more spreadsheets, no more surprises on the bill.

Buildings that run on the market
Building systems optimised against spot prices
Heating and cooling shift to the cheapest hours, without touching comfort.
Solar, batteries and EV chargers scheduled as one
Forecasting, nomination and asset optimisation in a single loop.
High-IRR energy assets
Know where a battery pays back best, and how big it should be.

Pilot the smart buildings, then scale
A first phase, before any active steering, already answers the questions that matter.
What does each building cost per quarter hour, and why?
Can we hedge prices further, beyond PPAs and spot price exposure?
Is a battery worth it, and where does it pay back best?
How big should each battery be: common areas or whole building?
How far can existing building systems be optimised against spot prices, and what would that yield?
How much value does automating reporting and invoice checks deliver?
What can you sell to tenants: power, heat, supply, solar, storage?
Who pays for a battery when tenants share the gain?
Buildings and energy buying, run as one system
Energy costs down significantly
High-IRR investments in energy assets
New energy offers for tenants
A lasting competitive advantage
