OurDesign–ourVision–your +


5 Our Design – our Vision – your +

5.1 Design Process

The design process was divided into three phases:

First phase: Five ideasInthefirstphaseoftheprojectweworkedonfivedifferentideas.Wedevelopedavision for a context, mobility strategy and urban density. To achieve a wide range ofideasweworkedinfivegroups.Eachgroupworkedondifferentideasandconcepts for regarding the issue of urban density. Ideas for technology elements, solarusage,energyefficiencyandstorage.Threeofthesefivegroupswereselected to carry on and focus on their concepts.

Second phase: Three conceptsWe continued with three concepts. All three teams developed their projects further and broke them down from an urban scale to a prototype that would be exhibited in Versailles. The three prototypes should tell the story of the context and its concept.

Third phase: One projectIn the third and last phase we decided which concept would represent Switzer-land in Versailles. All the groups joined together to work as one team on the same project.

Current state of the projectWe are currently working on optimization and spatial design. The concept and project from the third phase was adopted and developed further. Since Septem-ber 2013, we have been working on detail work and concrete plans using the internal exchange of ideas and also by addressing external critiques. In this way, we aim to complete the redesign phase by early November 2013 and will then focus on the implementation phase. We will build our house between January and May 2014.

5.2 Our Philosophy In the future, ideal access to desirable things such as rooms, objects, services, mobility and energy will be very important. Using a cycle of sharing and exchanging, we activate that notion of ideal access in our project entitled your +. Anentirenetworkspansacrosssociety,contributingtomoreefficientenergyusetosaveresourcesandachieveaddedvalue.Ourunderstandingofself-sufficiencyis demonstrated in a living model. That is why with your +, we not only seek a solution for one location, but also a solution within a standard urban context.

5.3 Cooperatives in Switzerland A group joined together to follow a common goal. That is the underlying principle of a cooperation, which has a long tradition in Switzerland. Centuries ago, cooperatives were formed in central Switzerland in the form of «Alpgenossen-schaften», which had the purpose of sharing their land irrigation systems. Since then, the idea of living and working together has been deeply rooted in Swiss society. We pick up on that with our concept your + and interpret the idea of a cooperative in a new way.

5.4 Self-sufficient Lifestyle through Diversity

We seek heterogeneity. Different users and residents create a broad diversity and mutually expand their options through a cycle of sharing and exchanging. User-specificofferscanreducespatialandmobilityrequirements,therebypreser-ving resources.

Concept follows Context


6 Concept follows Context

6.1 Urban Development in LucerneThe contextual focus for the Solar Decathlon lies in urban areas. The urban planningdevelopmentinLucernerevealsseveraldynamicresidentialandbusiness areas around a strong core and old town zone. «Industreistrasse» is a central urban area with great potential for urban density, in which current themes could be addressed in an exemplary way. Industriestrasse is characterized by its proximitytoLucerneStationandLakeLucerne,alocalrecreationzone,butalsoalively area, which already has a diverse user group in a mixed socio-cultural context and is a perfect foundation for this vision. By using the concept of sharing and exchanging, we plan our project within this neighborhood since its characteristics are similar to many other urban situations in Switzerland.

6.2 Dense Building Development The your + project includes several types of buildings with various sizes and configurations.Forouryour + house we select three different room types and connect them to the your + pavilion. We present our living model in this way. The three cubes of the pavilion show varying grades of shared and private areas, which are all connected by the space +. They also create zones with different levels of privacy, along which the appropriate uses and room accesses are aligned. The spatial density and building form, the results of energy aspects and the ideal use of solar power generation, allow the new development to function autonomously.

6.3 Added Value A good social mix is desired to make an active, colorful life possible that can adapt to requirements and addresses various target groups. The urban concept is applied to multiple cities, so that maximum flexible mobility can be offered. We are creating a platform that conveys a message - a message of a new life model, your +,youraddedvalue.Everyonebenefitsmutually,everyonetakesandeveryone gives, everyone is networked with each other. The lifestyle focuses on using instead of owning and we provide the general conditions. The focus is on people, not money – objects, energy, shared spaces and experiences.

7 The your + House Concept

7.1 Architecture – the Concept of Sharing

The pavilion represents our philosophy, an example of the sharing concept as a builtvision,providinginsightintooursystemandtheLucernecontext.Itcontainsthe three most important rooms – a common sharing room with flexible use, a semi-public room with a kitchen, and a private bedroom area with bathroom facilities. These three rooms are presented as an independent volume that is combined with the space + that also acts as an accessing area.

7.2 FlexibilityThe cubes can be connected in a variety of ways. Thus various spatial situations and expansions are generated. Differently prioritized corridors indicate the relevant character of the subsequent rooms. Those transitions between the individual cubes are formulated to create switchable zones that can be allocated to one or an other cube depending on the users’ requirements. Such flexible use is supported by multifunctional furniture.

7.3 Functionality of the 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,becauseitisinsulated,ratherthanair-conditioned.Dependingonthetime 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 maintain comfort conditions almost throughout the year. Passive benefits in space +

7.4 Energy Concept

Sustainable constructionSustainable development is influenced by ecological, economic, cultural and social criteria. All these criteria are taken into account when choosing the building method. A modular building method with flexible connections enables transport to Versailles, dismantling and material reuse.We regard the diverse timber building tradition in Switzerland and the know-how it entails to be a local resource. A timber construction method from native wood forms an ideal basis for constructing the three cubes and also has an excellent energy balance with special attention paid to the grey energy. The challenge of a timberconstructionmethodliesingeneratingsufficientstoragemasstostorethe heat created during the day and release it during the night. That is why the project your + works with materials that have strong storage properties, making them energy carriers.

Photovoltaics The photovoltaic system has the aim of generating as much energy as possible in combination with limited performance. That is why we use a sun-tracking system. In the your + project, we seek solutions that achieve large energy yields per square meter, have little to no cell aging, with high performance in high temperatures, while operating at low cost with a low energy input. That is why wedecidedtousesolarcellswithHeterojunctionTechnology(HJT).Theircelldesign has a high light yield and good performance in diffusing light. That ensuresahighlevelofeffectiveness.Furthermore,HJTcellshaveasignificantlylowertemperaturecoefficientthanconventionalsiliconsolarcells.The «SmartWire Connection» technology is an attractive combination with the HFT cell: It combines the advantages of leading photovoltaic technologies to improve the overall performance of cells and models, thereby achieving a sustainable reduction in solar power production costs.Other advantages are achieved through the relatively simple low temperature manufacturing concept, which is economically attractive because it saves energy and requires fewer production stages.

Heating/Ventilation/SanitaryWe use thermal solar collectors to produce hot water and heat the building. Usingvacuumtubecollectorsallowsustoachievehighlyefficientperformanceand also protects against overheating or freezing. Comfortable room temperatures are achieved through heating and cooling ceilings. The exchange of air is ensured through decentralized ventilation devices with integrated heat and humidity recovery. Rainwateriscollectedtominimizewaterconsumptionandcanbeusedforvarious sanitary facilities. The resulting wastewater is largely processed and reused in another cycle.

Electrical conceptToensureanefficientoperation,allconsumersmustbenetworkedwitheachother. That allows devices to be switched on when there is enough available power. Excess energy is temporarily stored to lessen any power supply peaks from the photovoltaic system. That energy is used to alleviate consumption peaks and thereby ease the burden on the public power grid.

BatteriesThe energy absorbed by the PV system will be stored in batteries. They will be networked with a load management system. This ensures that peak power is not suppliedtothegrid,enablingthehousetobeself-sufficientaftersunset.Thee-bike batteries are combined to create a single storage unit that every inhabitant has access to it. If required, a battery can be taken from the bank and used on an e-bike to ride to work. At home the e-bike can be used as a stationary exercise bike, the amount of training can be used to charge the battery. Mobile devices can also be charged with a USB connector.

Building automationBuilding automation has three parts: energy management, comfort management and additional functions. Energy management deals with operating the battery bank. The aim is to break down peak electrical performance periods and store the surplus energy for periods with less yield. Active and passive systems influence the comfort conditions and are operated according to requirements. Additional systems are used for safety, security and irrigation.
