How HAUT, one of the world's most sustainable buildings, turns EV charging data into revenue

HAUT is no ordinary residential tower. The 73-meter-tall building in Amsterdam's Amstelkwartier spans 21 floors and ranks among the tallest hybrid timber buildings in the world. Holding a BREEAM Outstanding certificate, the highest sustainability rating available, HAUT serves as an international benchmark for innovative timber construction.

Sustainability here goes beyond the structure itself. The building features rooftop solar panels, a battery energy storage system, and 53 of its 56 parking spaces are equipped with EV charging stations. The charging infrastructure includes load balancing, and the battery provides backup capacity and powers the charging stations directly. The parking garage is spread across two levels and accessed via two car lifts, an exceptional setup for a residential tower.

What was the challenge around EV charging data and ERE credits at HAUT?

Behind this impressive sustainable infrastructure lies a significant administrative challenge. The building has three main utility connections: one for the residential units, one for the ground floor, and one for the shared spaces, including the charging stations, which together account for approximately one third of total energy consumption.

In 2025, the Homeowners Association (HOA) wanted to convert the charging data from all those stations into HBEs (Emission Reduction Units, or EREs, from 2026 onwards) and generate financial returns from their green infrastructure. But that proved easier said than done.

"The NEa does not make it easy," says Carel Bal, HOA chairman and the very first buyer of an apartment in HAUT. "The regulations are strict, the reporting and documentation requirements are extensive, and linking the solar panels and battery to the charging data adds another layer of complexity. You really need a specialized partner."

The solution: Voltico manages the entire process to turn charging data into income

HAUT chose Voltico, which took full ownership of the process, from collecting and processing the charging data to submitting the claim to the NEa and handling the final payout.

Carel elaborates: "Voltico's platform automates the entire process end-to-end, including continuous data quality checks. The first claim generated thousands of euros in HBEs. A strong result for the first year, and earnings will only increase as more residents switch to electric vehicles."

Why are ERE credits relevant for the HOA?

ERE revenues flow directly into the HOA's shared reserve fund, resulting in lower service charges for all residents, a concrete, measurable benefit for the entire community.

But it goes beyond financial returns. EV adoption becomes more attractive when the charging infrastructure also generates income. It strengthens the building's sustainability profile with a verifiable contribution to CO₂ reduction in road transport. And it makes HAUT an even more compelling investment for forward-thinking residents.

"Given the significant costs involved in building out the entire charging infrastructure, it's great that we as an HOA are now getting a return on that investment," says the chairman. "And Voltico guided us through the entire process from A to Z."
