Energy-neutral homes on DC


Zero-On-The-Energy Meter

The four construction companies Ballast Nedam, BAM, Dura Vermeer and Volker Wessels have set up the national project "Stroomversnelling" (translates to Rapids) with six housing corporations planning to renovate, from 2014 to 2020, more than 110,000 houses into energy -efficient homes, called "Zero-On-The-Energy Meter" homes.

Innovative DC-DC system and DC smart grid

Direct Current Ltd works in co-operation with BAM to implement in three steps a centralized smart DC system, as depicted in the concept drawings below. In phase 3, the house will eventually be entirely connected to the DC net and fully operate on DC. In mid-April BAM has started renovating a prototype phase 1 in Soesterberg .


Phase 1

Installation of an intelligent DC system by Direct Current Ltd which makes a DC smart grid possible. DC USB sockets are connected to the DC smart grid. This USB wall outlets are supplied with DC for all the electronics that operate on DC, such as the computer, mobile phone, and TV.

Phase 2

Further development of the smart DC system. Making DC units and heat pumps DC-compatible and connecting them to the DC smart grid . Connecting the LED lighting, which also operates on DC, to the DC smart grid.

Fase 3

Final phase of development of the smart DC system. AC socket connection (for non-DC devices) to the DC smart grid. Connection to a DC smart grid and DC storage in the district which will also be developed and realized.

This is an innovative concept that requires adjustment in the current legislation. The Ministry of Internal Affairs and the Ministry of Economic Affairs have signed a Green Deal to send the appropriate adjustment to the House.

Due to renovation of the house you are saving on energy by improved insulation and smart electric facilities. By harvesting renewable energy through solar panels, at a standard energy consumption of the house, the energy meter will add up to zero on an annual basis. The occupant pays only if more energy is consumed.
