The theme of sharing combined with the condition for modular assembly and disassembly lead the design team to the concept of a shelf. The walls are designed as large shelves – instead of only books the shelf includes insulation, facade elements and technology. In the interior, it is used as furniture, and for support. As a final function the shelf is just that, an actual shelf to share books and other items with co-residents.
Rather than creating a new modern and untested design, our innovation comes in the form of refining the old and tried forms of construction. Due to the short construction phase in Versailles, the prototype must be buildable within ten days. Two of the rooms will be complete modules to transport, and therefore erectable in any weather. The third room will be erected in the first fair weather situation as it will be transported in a separated state.
Switzerland offers a wide variety of wooden materials and has a rich tradition in woodworking and craft. The pavilion differentiated qualities and products. Through natural treatments and the separation of the various elements we ensure that normal wear can easily be maintained, and when necessary, replaced.
In the dramaturgy of the tour the visitors will be shown that the three spaces are to be understood separately from each other. In order to differentiate the three rooms, different materials and colors are used, as appropriate for the different uses proposed for each living quarter. Everyone gets a room with its own identity. The prototype is an example from a multi-story residential building, and portraying this is an important aspect of the project.
In the prototype, the concept is clearly visible from an Anergy-net standpoint, and illustrated by a specific system. In the summer cooling phase the cold storage is filled with cold water. During the daytime, this cold water can be used to cool the house through a heat pump does not require refrigeration machine.
Thermal solar collectors provide the building year round with warm water for heating and the heating of domestic hot water. In addition, hybrid photovoltaic cells provide supplemental heat in the cold storage, which serves as a heat source for the heat pump.
Energy in the correct place at the right time is the principle to follow for the highest efficiency.
To reduce fresh water consumption, sophisticated systems are used in the prototype. For water-intensive operations, storage and reuse of rainwater supplements in appropriate situations such as the flushing of wastewater and shower systems. Drain water is also stored in order to provide for watering processes such as the wetting of the dry cooler. Reducing water consumption allows the strain of wastewater treatment to be reduced.
To provide a pleasant room climate, air quality is highly important. Decentralized ventilation units supply each room according to its respective need for air. Due to the direct placement in the facade no ventilation channels are needed. Energy efficient and quiet, these ventilation devices provide new possibilities in the design and construction of spaces.
To ensure the most efficient operation, all consumers need to be networked together. Energy can be managed in such a way that allows the maximum usage in peak production times, and savings when production is low. In order to reduce any peak performance waste in the PV system, the excess energy is temporarily stored in batteries. This energy is used by the consumer to buffer and operate the building as independently as possible from the main grid.
The energy storage of the project takes on various tasks in the system of the building and mobility. Besides the important tasks in the electrical concept, they also play an important role in mobility. The charged batteries are used for e-bikes, making it easier to ride the bike as a main means of transportation. Another concept uses the bicycle as a home trainer and saves the energy produced back into the battery, to store and be available to the your + house again.
The building automation system has three main components; energy management, comfort management, and additional features. The energy management is responsible for the peak and lull production phase management. In this case, one would like to break electrical power peaks and store excess energy for low-performance times. Active and passive systems affect the comfort conditions and are operated only when necessary. Additional systems are designed for safety, security and irrigation of plants and PV panels.
The different switching algorithms process internal and external inputs, and cohesively maximize efficiency.
In order to build energy-efficient buildings, it is important that holistic considerations are made in the planning process. In order to assess the effects of the solutions in the different stages of the project and respond appropriately, the planning process is supported with simulations.
