Operation & service

We look after your building.

With das.care we operate and monitor your entire energy system – from the building envelope to the energy billing. The goal is a building that runs energy-efficiently, economically and climate-friendly for good.

Starting point

The manufacturer warranty ends where operation begins.

Without das.care, only the warranties of the individual components apply. They cover material and production defects – not the interplay of facade, roof, storage and control.

01

Every manufacturer on its own

Module, storage and inverter each have their own warranties, deadlines and contacts. Nobody is responsible for the system as a whole.

02

Faults without material defects

Wrong settings, an installation issue or components that don't work together – none of that is covered by any manufacturer warranty.

03

The yield drops unnoticed

Without monitoring, a gradually weakening plant only shows up when the annual statement arrives. By then the yield is lost.

Life cycle

das.core generates. das.care operates.

das.core turns the building envelope into a power plant. das.care keeps that power plant in optimal operation across the building's entire life cycle – technically, energetically and commercially.

Generate

Energy comes from the envelope

BIPV facade, PV roof, storage, heat pump and charging infrastructure form the power plant. Delivered and integrated through das.core.

Operate

The system stays on target

Monitoring, maintenance and service keep the plant at its design point for decades. Deviations are reported before they cost yield.

Optimise

Operation becomes self-sufficiency

Load management, peak shaving and storage control shift energy to where it is worth most – up to 70 % self-sufficiency in the ecosystem package.

Modules

Five modules. One operation.

Each module can be booked individually and added at any time. Billing is per square metre of gross floor area and month – predictable, without surprises.

All prices per square metre of gross floor area per month, plus VAT.

das.care.guarantee

Without das.care, manufacturers are liable. With das.care, we are liable for the system.

The difference is not the length of the guarantee but its subject: components or plant.

das.care.basic monitors and checks once a year. das.care.plus additionally includes regular maintenance, spare parts management, prioritised fault resolution and on-site service – and extends the manufacturer warranty by approx. 5 years.

Per square metre of gross floor area and month: € 0.15 for basic, € 0.45 for plus, € 0.25 each for management and flow, € 0.35 for clean. Usage-based items add € 6 per bill, 10 c per kWh energy platform and a 15 % peak shaving fee.

Yes. Each of the five modules can be booked individually and added at any time. Bundle all of them and das.care.all.in.one gives you a 5 % discount.

The das.care.hotline is staffed around the clock. After a report, the service is ready to deploy within four hours. With das.care.plus, fault resolution is additionally prioritised.

Setting up das.os costs a one-off € 5,000. After that, monitoring, control and reporting run through the platform.
