Secondly, Switzerland’s new land-use law callsfor building in existing neighborhoods instead of constructingongreenfieldlocationstoallowthemostefficient use of the country’s limited constructibleland.

Two Swiss specificities aggravate the afore-mentioned challenges. First, Switzerland willundergo a significant population growth from 8.4 million to 9.8 million by 20352. Providing livingspace for an increasing population is particularlychallenging due to a significant part of the countrybeingmountainous.This,coupledwiththehighvalueplaced on direct democracy, citizen involvementand the importance of finding consensus, createsanenvironmentwherethetwonewlawscanonlybe implemented in an integrative and collaborativemanner.

Todothis,weneedtochangeourlifestyles,thewaywebuildandthewaywetravel.We need to engage in both an urban and energy transition.Thesechangesarebestachievedbyworkingonaneighborhoodscale,allowing forcommitmentandengagement from theentire community. The NeighborHub provides theidealplatformfromwhichthiswillhappen.Webelievethat localstakeholders fromboth thepublicandpri-vatesectoraswellasassociationsandNGOsarethekeytoaneffectivetransition.

It promotes these themes amongst thepopulationbybeingactiveonthree levelsof involve-ment.TheNeighborHubisashowcase of sustainable living, a space where neighbors can learn through experienceabouthowtolivemoresustainablyandaspaceforthecollaborative planning ofSwitzerland’sneighborhoodsofthefuture.

The NeighborHub provides the perfect space fromwhich a neighborhood can kick-start its urbanand energy transition, enabling Switzerland to createthemostsustainablehousing,neighborhoodsand lifestyles possible. By taking on this role, the NeighborHub becomes the home of Switzerland’s urban and energy transition.

As the world grapples with climate change and resource depletion,many countries are committingthemselvestotakingthenecessarymeasurestolimittheglobalincreaseintemperaturetoamaximumof2degreesCelsiusbytheendofthecentury.

Switzerlandtakestheseandothercriticalchallengesto heart. It aspires to protect its landscape fromurbansprawlwhiledrastically reducing energy con-sumption and increasing the amount of renewable energyused.

The NeighborHub provides the ultimate solutionto these critical challenges facing Switzerland.Firstly, as laid down by the country’s new energy law, Switzerlandmust end its use of nuclear power, dramatically increase use of renewable energy andlowerenergyconsumptionby43%in2035comparedto20001.

Candidates for urban transition

85%ofSwitzerland’spopulationof8.4million live in itsurban centers. These need to be densified3 in aqualitative way to avoid urban sprawl and conservethe country’s limited constructible land to allow forlongtermsustainablegrowth.Atthesametime,urbancenters need to provide sufficient living space that offers a high quality of life despite a growing popu-lation. To overcome these challenges and achievea qualitative urban transition through collaborativeplanning,urbancentersneedNeighborHubs.

Partners

The NeighborHub is composed of a collection ofpartnerswhoarewilling to invest in a new kind of infrastructure,onethatwillenablearapidandcoher-enturbanandenergytransition.

Private entities can demonstrate solutions byshowcasing their technologies in this exemplarybuilding, while public institutions can use it to carry out collaborative planning. NGOs or associa-tions can propose activities inside theNeighborHubtoraiseawarenessofsustainabilityorspecifictopicsrelevant inaneighborhood.Toestablish theviabilityand interest of having different stakeholders cometogether, we interviewed potential partners activein our target market of Fribourg : Switzerland’slargest construction company, Implenia, Fribourg’senergy supplier, Groupe E, and the city government of Fribourg. Due to Switzerland’s direct democracyandinstitutionalprocesseswhichrequirehighpartic-ipationfromallstakeholders,planningprocessesareparticularlylengthyandexpensiveasallpartieshaveampleopportunitytoslowdownorblockanykindofproject.ThisobstacletoachievinganurbantransitionisovercomebytheNeighborHub.

The city of Fribourg has a major urban development process coming up,whichwill seethe creation of a completely new neighborhood.11acresofwhatarecurrentlymilitaryinstallationson prime real estate close to the city centerwillbe closed in 2020, and control of the land willbe passed from themilitary to the city for resi-dential development. During our interview withthe city’s architect,wewere able to confirm theNeighborHub’scapacity toactasaplatform for exchange between different stakeholders in the development of the new neighborhood.The projectwillrequirefiveyearsofplanningfollowedbyfifteenyearsofconstruction.Thecity’sarchi-tectsuggestedthattheNeighborHubcouldbethefirst building initially set up on the undevelopedland,andserveas thecentral planning location fortheprojectandlaterbecomingacentralmeet-ing point for the community whichwillpromoteasustainablelifestyle.

Groupe E has been trying to move ahead witha project to construct a small wind park around the city of Fribourg but is encountering resistance from various stakeholders like localresidentsandenvironmentalNGOs.TheycouldinthiscaseimagineusingtheNeighborHubasaplacewheretheycan,togetherwithotherstakeholders suchaslocalgovernments,createaplatform for discussionabouttheproject.Toachievethis,otherstakeholderssuchasnatureprotectionNGOsandcitizen associations could use the NeighborHubtodiscuss theprojectandfindcommonground,thistooenablingurbanandenergytransition.

Faster urban planning processes allow stakehold-ers to save time and money. They not only benefitconstruction companies like Implenia, but alsoenergy companies which encounter stiff resistance toprojectsaimingtodevelopproductionofrenewableenergy.

Impleniahasalready tried tobring stakeholders together to learn about their points of view andto be able to deal with them. The advantage ofthis is thatpotential solutions toconflict issuescanbefoundatanearlystage,reducing friction, expenses and loss of time during a potentiallylong process, from the formal launch of the projecttocompletion.

Implenianeedsaboutnineyearsfromthelaunchof a large real estate development project to itscompletion, a certain amount of this time beingused up by democratic processes where the projectisdiscussed,re-evaluatedandoftentakento court. The company saw that by involving the local neighborhood community from anearly stage, project length can be reduced by 10-15%.Theysee theNeighborHubasaperfect locationwherethisprocesscantakeplace,thuscontributingtofacilitatingtheurbantransition.

Planning collaboratively

The last step is involving all stakeholders in the process of rethinking an urban area.Having discov-ered sustainable solutions and having learned andexperiencedtogether, people will want to go further and be included in more global discussions.

ThecostoftheNeighborHubwillbereducedwhenitis industrially-produced.Thewooden frame ismadewith efficient advanced machinery that enables industrial production. Finally, by adapting the build-ing to Swiss standards that require fewer technicalfeatures (ie no air conditioning and no fire safetysystem), we can estimate that the final product willcost800,000CHF.

Asshownbytheabove-mentionedinterviews,publicinstitutions and companies are convinced of theneed for such an infrastructure. They will thus beinclined to enter a partnership and supply land fortheNeighborHub.Thecostofsuch land isvaluedat200,000CHF9.

The total investment can be summarized as anannual cost taking into account the building’s life expectancy (25years10), theamortizationand the in-terestrate(2%).

Referringtheinvestmenttoannualcosts(60,000CHFperyearwiththeland)helpscomparetheinvestmentcapability of different stakeholders (public / privateinstitutions andassociations) and shows that it is averyaffordable expenditure for long-term impactful resultsindrivingtheurbanandenergytransition.
