More options and less floor space with intelligent layout and more usable living and working space
For urban planning implementation, we chose the example of a heterogeneous quarter in Lucerne with an ideal infrastructure. Our development plans four different buildings that are networked with each other, while also remaining in contact with neighbouring buildings.
Our project has three types of rooms, each with different uses. my room has the greatest intimacy and is used privately by one person. our room is the kitchen and dining area, which can be used by two to five other people depending on the situation. your room is the most public part of our project – since everyone is able to rent it according to his/her requirements. That creates added value such as efficient use of space, social synergies, flexible use potential and low overall rent costs. The three different room types are connected by space+, which serves as a lively, communicative connecting element with a wide range of use potential.
Three different room types connected by the space+ – in the urban context as well as in the prototype
From that urban planning context, we chose an example of each room type, developed our prototype for the competition in Versailles and connected the rooms to the space+ unit.
So we generate a prototype, with which we present our concept at the Solar Decathlon Europe 2014 in Versailles.
Cutting-like plan of the urban project
The ever-growing population and with rising energy and land consumption continues according to the trend of recent years. Resource consumption per capita compensated, to some extent technical progress in equipment and construction technology. New thinking and behaviors are necessary for establishing a sustainable resource management. We strive for with our idea of the parts and swap to conserve resources and to use land efficiently. In our concept of living rooms are shared and created to replace a platform to objects and to use flexible mobility. The base is us, the concept of co-operative which is firmly anchored in Switzerland for decades and focuses on the principle of mutual benefit.
Development of the population and their needs
Different parties may designate private-and share common space according to their specific needs – Modular design focusing on the purpose of social cooperative life.
Life with and without the concept of your+
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.
