DESCRIPTION |

|
|
|
|
| A Building like an Organism |
|
|
|
 The active energy building, developed by falkeis.architects, emerged as the winning project from an internationally invited architectural competition for an apartment building in Vaduz / Liechtenstein. After a 6-year planning, research and implementation phase, the building was recently completed. Innovations realized on the highest technical level "directly on the object" now make the Austrian architect a bravura piece.
 Main goal of the active energy building is to create a sustainable structure producing more energy than it consumes. The building is energy autonomous as it utilizes renewable energy exclusively, produces energy locally and employs new techniques regulating the building climate.
Investigating new strategies for the reduction of carbon dioxide emission, the whole project is developed on the inherent logic of sustainability. Sustainability as a holistic concept becomes form-generating. This applies to the massing of the building, as well as to the construction of the load bearing elements and the development of the energy technology. On the level of construction, sustainability is defined by the adaptability of the building itself. The design and distribution of the load bearing elements allows for spatial reprogramming over the entire lifespan of the building without impacting load bearing components. On the level of energy design, the building is sustainable by using renewable energy forms exclusively, and due to the local energy production and new techniques regulating the building climate. |

 In close cooperation with experts from various fields some of the research findings for the ‘active energy building’ were developed further into innovative products such as the acoustically active 3D light fields, the high-performance concrete with an outstanding reproduction quality or the multi-component molding technique. Some of the technological inventions yielded a patent, like the movable building envelope, or were built as prototypes creating new knowledge in the field of digital fabrication, like the complex 3D Voronoi load bearing structure and the 3D freeform textile building envelope, working as a shading device. |

| Energy concept |
|
|
|
 The energy supply is based on renewable sources: geothermal energy and passive and active utilization of solar power. Passive solar gains (3.1) are part of the buildings´ heating system. Active usage (3.2) of solar radiation includes solar power production and systems to support climate regulation in the building.
 Therefore, solar and interstellar radiation are made productive for air conditioning the building by means of facade elements with latent heat storage devices specifically developed for the ‘active energy building’.
The building works as a networked structure managing a local cluster. It is a smart node interconnecting existing buildings, sharing information as well as energy surplus. |
