Simply explained

Electricity-only house

A key component of HOWOGE's sustainability strategy is the decarbonization pathway for its existing buildings. This aims to permanently reduce CO₂ emissions from building use – for example, from heating or hot water. We strive to implement construction projects as so-called Efficiency House (EH) 40 – according to the principles of the "Climate-Friendly New Construction" (KFN) funding program. One of the solutions for greater climate protection in the building sector is our "electric-only houses."

What does "electricity-only house" mean?

HOWOGE's "electric-only houses" are buildings that are powered exclusively by electricity to meet their energy needs. Whether for heating, showering, or operating the necessary building technology, no energy generated from fossil fuels such as oil, gas, or coal is used.

How does an "electric-only house" work?

Simply put, everything in HOWOGE's "electric-only house" runs on green electricity. To minimize electricity consumption and make optimal use of the energy used or generated, the building must be constructed to be highly energy-efficient or (in the case of existing buildings) retrofitted. Besides excellent insulation, this also requires, for example, well-insulated windows and the use of energy-efficient appliances.

Power supply:

HOWOGE is also an electricity supplier. As on many of its residential buildings, the "electricity-only house" also uses photovoltaics to produce solar power on its roof. This power supplies the building's technical systems.
Some buildings already use a battery storage system. This allows the house to be supplied with electricity even when it's dark or the sun isn't shining brightly enough. Excess electricity generated is fed into the public grid – because, of course, even the "electric-only house" is connected to the grid to ensure a reliable power supply under all circumstances.

Heat:

HOWOGE is using efficient underfloor heating in its new buildings. The heat energy for this is supplied by a heat pump, which, depending on the model, extracts heat from the ambient air or water and transfers it into the building, even in winter. Some new buildings also feature controlled ventilation with heat recovery, such as the HOWOGE new building project at Sewanstraße 256A-C.

Warmwasser:

Die Warmwasseraufbereitung in den Wohnungen erfolgt dezentral. Hierbei werden elektrische Durchlauferhitzer oder Trinkwasserstationen eingesetzt, die das Kaltwasser nur bei konkretem Bedarf auf 45°C erhitzen. Somit muss nicht rund um die Uhr unnötig Warmwasser (etwa in Kesseln im Keller) gespeichert und bereitgestellt werden, was ebenfalls zur Energieeinsparung beiträgt.
Zusätzlich unterstützt die HOWOGE ihre Mieterschaft dabei, den Wasserverbrauch zu senken – zum Beispiel durch Handbrausen mit einem Durchfluss von nur 8 Litern pro Minute. Im Vergleich zu den üblichen 12 bis 13 Litern bedeutet das eine erhebliche Wasserersparnis.
