Highly efficient photovoltaic modules on the rooftops ensure the power supply of the prototype.
The excess electricity supplied to the grid and the visitors. The building technology is interconnected and automatically responds to changes in the weather.
Energy concept for heating and cooling
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.
Innovative solutions in sanitation and ventilation
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.
Functionality of space+
The space+ is a connecting element that assumes several roles. It is an accessing area and therefore has an important social status. The accessing area structures the different levels of privacy, organizes the uses and is formulated for communal life. In addition to social aspects, the space+ provides passive benefits, because it is insulated, rather than air-conditioned. Depending on the time of year, it regulates the interior climate with passive measures and increases the daylight yield. Through the natural ventilation in the summer and the heat through the skylights in winter, it can be used almost throughout the year. Surplus energy is made available to visitors in accordance with our philosophy.
With respect to the architecture, the energy-consuming areas will also be flexible in terms of a zone demand control. There are two different types of spatial energy management (comfort and stand-by), which react quickly because of the air source heat pump. No energy is required to support the self-sufficient rooms that are not in use.
Electricity concept in the urban project as well as in the prototype
The urban context provides the networking of energy potentials to generate the possibility of energy in urban areas, and its excellent location allows the building to provide for several households. Utilizing a smart grid, entire complexes and neighborhoods are connected with energy technology, which can help meet their needs for heating and cooling efficiently. Because the building will produce a positive amount of energy over the year, excess unused energy can be shared to the neighbors and connected buildings to improve resource management.
Share energy means saving resources.
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.
Grid Living & Mobility Concept
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+ prototype 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.
Simulation as a predictive measure
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.
The rooms can be connected in a variety of ways. Thus various spatial situations and expansions are generated. Those transitions between the individual cubes are formulated to create switchable zones that can be allocated to one or other cube depending on the users’ requirements. Such flexible use is supported by multifunctional furniture.
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 prototype 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.
Materialization in the interior
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.
The prototype represents our philosophy, an example of the concept of «Smart Sharing» as a built vision, providing insight into our system and the Lucerne context. For our your+ prototype we select three different room types and connect them by the space+.
It contains the three most important rooms – a common room, the your room with flexible use, a semi-public room with a kitchen, called our room, and a private bedroom area with washing facilities, my room.
The three cubes of the prototype show varying grades of shared and private areas which are connected by the space+. This area is a meeting zone and provides access to the cubes. It has an important social meaning.
