The future of building.

Smart design.

“Of the 7.4 billion people living on Earth today, two billion are still in childhood, that is, less than 16 years old. These two billions will require their own homes, jobs, and infrastructure in the next 16 years.

In 1930, a total of two billion people lived on the planet. This means that we will need to rebuild the world of 1930 in the next 16 years. If we were to do so according to German standards, we would need 1,000 billion tons of concrete and bricks. These are neither available nor producible.

It is high time to rethink building.

Werner Sobek
on the occasion of the awards ceremony for the Fritz Leonhardt Prize on July 4, 2015.

The hour of need: sustainable development.

The Agenda 2030 adopted by the international community is a blueprint for the future. Its key objective is to ensure that all human beings can enjoy prosperous and fulfilling lives. This includes economic, ecological and social development aspects. aktivhaus is dedicated to the areas in building construction.

Our definition of sustainability.

Taking the three pillars of sustainability, ecology, social and economic development, we set our own aktivhaus goals.

1. Ecological Goals

Triple Zero®: Zero Energy Building, Zero Emission Building, Zero Waste Building.

2. Social Goals

To create more affordable housing for all generations using fewer materials.

3. Economic Goals

Lower initial investment and life cycle costs thanks to the use of renewable energies and materials.

aktivhaus – the first house with the power to change the world.

An essential part of the aktivhaus concept is to sustainably produce energy from regenerative sources. The roofs of the aktivhaus have been fitted with connections for photovoltaic systems. The alphaEOS intelligent energy management system is the first to offer a heating control system that adapts to user behavior and every single room automatically and is self-learning. It also ensures predictive temperature control while offering maximum energy savings.

Sustainability in its purest form: Triple Zero®!

Zero Energy Building

The building does not use more energy on an annual basis than it produces itself from sustainable sources.

Zero Emission Building

The building does not produce any CO2 or other harmful emissions.

Zero Waste Building

At the end of the life cycle, all components can be completely transferred to biological or technical cycles. The plot of land can be restored to its original state without leaving any contaminants or residue behind.

Triple Zero® is a standard developed by Werner Sobek standard that defines the requirements a sustainable building should ideally fulfill.

The aktivhaus criteria for sustainable building.

Aktivhaus developed ten quality criteria for building more buildings using fewer materials. They ensure sustainable building and living that features high a aesthetic value. Because building a house also means creating homes for people, especially for young families. The individual floor plans make aktivhaus a house for all generations that is affordable for average income earners both in terms of rent rate and purchase price.

Integration into existing structures

The aktivhaus can be integrated into existing structures thanks to its lightweight construction and design of the facades

Individual floor plans

An aktivhaus module features an individual floor plan with an internal layout of 2-3 rooms that can be combined
with other elements to make large apartments and flexibly change the location of doors and windows

Generation and age appropriate

aktivhaus makes it possible for generation after generation to live in the house. The ground floor features a barrier-free design. The other levels have age-appropriate flooring, door widths and bathrooms.

High living comfort

The aktivhaus offers a high level of living comfort with its lighting and ventilation concept.

Can be dismantled and rebuilt

The floor plan of the aktivhaus can be subsequently changed or even dismantled and rebuilt elsewhere

Ecological building materials

The aktivhaus is made from organic materials, in particular, wooden elements and other renewable resources

Building that is easy on the environment

The aktivhaus stands for construction that saves on resources thanks to the use of recyclable materials, its low weight, and low foundation requirements

Use of renewable energy

The aktivhaus is energy efficient, complies with the EnEV 2016 and uses renewable energy.

Delivered ready-for-occupancy

aktivhaus can be delivered three months after the order is placed ready for use and occupancy, meaning occupants can move in right away thanks to industrial prefabrication.

Affordable building

An affordable fixed price per square meter of floor space is set for planning, manufacturing, and transporting the aktivhaus modules.
