EV charging for residential and commercial real estate
Electric vehicles are changing what tenants, employees and guests expect from a building. ista supports housing companies, property managers and commercial property owners in making charging work at scale: planned to fit the building, integrated into the existing energy supply, and billed accurately for every user.

Charging infrastructure is becoming part of the building, not an accessory
The shift to electric mobility is getting faster. Most charging takes place where vehicles stand for hours: at home and at the workplace. For property owners, this turns charging from an amenity into part of the building's technical infrastructure — with the same questions that apply to heating or metering. How much power is available? Who is allowed to use it? Who pays for what?
Regulation is moving in the same direction. Across Europe, the Energy Performance of Buildings Directive (EPBD) increasingly requires cabling or charging points in new builds and major renovations, and national programmes support retrofitting existing stock. At the same time, tenants and commercial users ask for charging before they sign. Buildings that can offer it stay competitive; those that cannot risk expensive retrofits later.
Multi-family buildings
In residential buildings, charging is rarely a one-off installation. Demand starts with one or two residents and grows over the years, which makes the initial design more important than the first charging point. A well-planned energy and cabling backbone allows further charging points to be added without opening walls again.
Which charging model fits depends on how parking is organised. Dedicated spaces usually call for one charging point per space, assigned to one household. Shared or rotating spaces are better served by shared wallboxes that several residents can use with their own authorisation. Visitor parking may need semi-public charging with separate access and tariffs.
What all models have in common: consumption has to be assigned to the right person and billed transparently. That is where ista's core expertise in metering and billing comes in — the same principle we apply to heating and water, extended to charging electricity.
Commercial and industrial real estate
Commercial properties usually have more user groups than residential ones: employees, fleet vehicles, tenants of a multi-let building, customers and guests. Each group needs its own access rules, tariffs and often its own priority when power is limited.
That makes usage patterns central to the design. Office buildings charge slowly over a working day. Retail and hospitality need faster charging over shorter dwell times. Logistics and fleet locations depend on vehicles being ready at a fixed time, which turns charging into an operational requirement rather than a service.
Charging infrastructure also carries weight beyond mobility. It contributes to green building certifications, supports ESG reporting on Scope 2 and Scope 3 emissions, and is increasingly expected in commercial lease negotiations. Combined with on-site generation and load management, charging can also improve the overall energy performance of a site.
What a complete charging solution involves
The scope of services ista offers varies by country. In principle, a charging project runs through these stages.
Planning and design
A charging concept starts with the building: parking layout, available grid connection capacity, cable routing, the charging models required and realistic future demand. Planning for expansion at this stage keeps later additions affordable.
Energy and charging infrastructure
Energy and cabling infrastructure is installed, charging points are commissioned and meters registered where required. Modular hardware lets charging points grow with demand, while intelligent load management makes efficient use of existing capacity.
Operation and billing
Ongoing operation covers monitoring, maintenance, repair, user administration, support and the supply of charging electricity. Billing turns measured consumption into transparent invoices per user, in line with local metrology rules.
Benefits
What charging infrastructure does for a property
- check
Asset value and lettability: Charging is becoming a criterion in rental and purchase decisions. Properties that offer it retain their appeal, especially in urban markets.
- check
Regulatory readiness: Meeting building requirements early avoids retrofitting under time pressure and at higher cost.
- check
Sustainability reporting: Charging with renewable electricity supports green building certification and ESG disclosure, and makes mobility emissions measurable.
- check
Cost control: Load management and needs-based expansion keep investment predictable and can avoid an upgrade of the grid connection.
- check
Tenant and employee satisfaction: A charging option that simply works — with clear access and clear invoices — reduces friction and complaints.
Frequently asked questions
AC charging points supply alternating current, which the vehicle's onboard charger converts to direct current for the battery. This is slower and well suited to long dwell times, such as overnight at home or a full working day at the office. DC charging points do the conversion themselves and deliver direct current to the battery, allowing much faster charging. DC is typically used where dwell times are short — retail, hospitality, or fleet operations with tight schedules.
A building's grid connection has a fixed capacity, shared with lifts, heating, lighting and everything else. If several vehicles charged at full power simultaneously, that capacity could be exceeded. Load management measures the load in real time and distributes the power that is actually available across active charging points. This allows significantly more charging points to be operated on an existing connection, and often avoids an expensive upgrade.
Each charging point records the energy it delivers, and each charging session is linked to an identified user through an app, a card or a fixed assignment. Consumption is then allocated and invoiced per user, separately from general building electricity. Where billing is subject to metrology law, the meters and processes used have to meet the corresponding requirements.
In many cases, yes. Whether an existing installation can be taken over depends on the hardware, the communication protocols it supports — OCPP being the common standard — and its metering capability. An assessment of the existing setup shows what can be integrated and what would need to be replaced.
ista worldwide — EV charging in your country
EV charging is part of our portfolio in selected markets. Where it is available, the charging models, service scope and billing formats differ, because parking structures, grid capacities and national law differ. The country websites describe what we offer locally, in the local language, and who to speak to.
