Energy-optimised construction in new buildings

All of these new buildings are steps towards "buildings of the future". With a range of new concepts, materials and technologies, the possibilities and facets of energy-optimised construction are being demonstrated. Whether an office and administration building, or a production hall, all buildings are designed for maximum workplace comfort and minimum energy requirements. They are scientifically evaluated over an extended occupation period, and optimised during completely normal operation. Each project description is updated here on an ongoing basis, and follows the project through its phases, from "planned", "constructed", "in operation" and "evaluated", through to "optimised".

Single-family homes with renewable electricity and heat provision

Climate-neutral building concepts are more in demand than ever before as a result of the latest energy policy requirements of the EU and the German federal government. In Freiberg, the performance of two single-family homes conceived as energy self-sufficient buildings was scientifically investigated for two years. For two different utilisation profiles, it can be shown that high solar coverage levels are possible, particularly for the power and heat provision.

Zero-energy primary school in a timber structure

In Halle, a school was built as a passive house using wood as a construction material. The school sponsor, an ecclesiastical foundation, wanted to use environmentally sustainable building materials and – with the energy-optimised building concept – ensure a high level of comfort while learning at manageable operating costs. The building envelope with a very high thermal protection standard and four-glazed box windows ensures an already low heat requirement, which is further reduced by means of the ventilation systems with heat recovery.

Sustainable university building in climate-neutral campus association

The spectacular new central building of Leuphana University Lüneburg interprets energy-optimised building in a different way. The claim of environmental and social sustainability is conceptually underlined by sidestepping the need for cooling, and by minimising power requirements for ventilation and lighting. Noteworthy is the natural ventilation through openable windows in combination with a self-shading façade and switchable glass.

Energy efficiency strategy for new hospitals

Hospital buildings consume considerably above-average amounts of energy. This is primarily due to the high amounts of energy required for their operational needs. The “Hospital Plus” project is therefore looking to develop energy efficiency strategies for hospitals and their operation. For this purpose, individual hospitals are being examined in more detail. One of them is the University Hospital in Frankfurt am Main. For the second construction phase, a new-build scheme is envisaged, which is currently being designed. The intention is to plan, build and operate the building in a functionally and energy optimised manner.

Energy innovations in energy plus child day care centre

This building is remarkable: the “Noah’s Ark” is a child day care centre that has a particularly exemplary design not just in architectural and building ecology terms but also in regards to the structural technology and energy use. The energy-plus building is designed to generate more energy than its users will consume. To achieve this, the building concept includes not only a large photovoltaic system for generating energy but also several innovative systems and components for handling heat and electricity in a particularly energy-efficient manner.

New office and laboratory building utilises waste heat recovery and geothermal energy

The building was to be particularly energy-efficient and significantly overcomply with the Germany Energy Saving Ordinance. Waste heat from the server and multimedia rooms of a nearby building is used for the heat supply system of the building, as well as geothermal energy extracted with a heat pump. The borehole heat exchangers also support the air conditioning of the building and the supply of process cooling energy.

Excellent architecture with a sustainability certificate

The new building for the Hamburg Department for Urban Development and the Environment (BSU), which was completed in 2013, is home to about 1,400 employees and, with its high architectural quality, is set to contribute to the urban regeneration of the hitherto rather neglected Wilhelmsburg urban district. The service and administration building also forms part of the Hamburg International Building Exhibition (IBA). The building complex, which consists of a tower and two wings, is exemplary in that it is energy-efficient, sustainable and cost effective at the same time.

Am 21. 6. 2013 wurde das Energy Efficiency Center in Würzburg feierlich eingeweiht. Es ist das neue Zuhause des Forschungsinstituts ZAE Bayern. Mit seinem Institutsneubau unweit des Hubland-Campus wollen Forscher viele neue Technologien demonstrieren.

Energy Efficiency Center as flagship building for technology

This is no ordinary building: In its new building in Würzburg, Germany, a research institute intends to test innovative materials, systems and technologies experimentally and evaluate their use options in new buildings and existing buildings scientifically. It is being built with innovative prototype building materials, building systems and technologies which can all be used for an energy-efficient building method to conserve resources.

University building with an innovative energy system

Erfurt University of Applied Sciences is expanding its traditional “Green Campus” with a modern teaching and laboratory building. The energy concept for the building features several innovative approaches that are aimed at achieving a particularly sustainable building operation. The use of district heating combined with an adsorption heat pump enables a rainwater cistern to be used as both a renewable heat and cold reservoir.

Z3 office building as a laboratory for sustainable construction

The “Z3” office building for the Ed. Züblin AG company utilises innovative concepts for the building structure and building services technology. With the new building the globally active construction company wanted to create more space for its staff at its headquarters in Stuttgart – and at the same time construct a laboratory for sustainable construction for the company’s own use. It was also intended that the Z3 building should combine the two existing buildings, “Züblin-Haus” (1984) and “Z-Zwo” (2002), in urban design terms to form a cohesive unit. At the same time Z3 has its own unique appearance thanks to its facade, which uses a modular timber frame structure.
