Concept House

Ontwikkeing van een duurzaam huis in een sociaal duurzame context


Concept House

• Initiatief: gepensioneerde ondernemer in de bouwsector die gelooft in volledig geïndustrialiseerde woningen

• Uitdaging opgepakt door: Prof. Mick Eekhout, Chair of Product Development TU Delft

• Projectleider beginfase: Dr. Wim Poelman• Project leader realisatiefase: Dr. Arjan van Timmeren


Waarom een Concept House van uit de TU Delft?

• Onafhankelijk van practische sociale beperkingen • Onafhankelijk van economische beperkingen • Gelegenheid om zelf te bepalen wat er gebeurt• Gelegenheid om resultaten te onderzoeken• Gelegenheid voor derden om te zien en te leren• Gelegenheid om reproduceerbaar onderzoek te doen• Gelegenheid om de industrie te stimuleren


Voorwaarden:

• Conceptuele ideeën• Visie op de toekomst• Financiële ruimte• Geschikte partners• Materialen en componenten• Mankracht• Locatie


Partners

• Voor elk betrokken materiaal/component zijn partners vereist

• Het aantal partners groeide voortdurend• Sociale complexiteit groeide voortdurend• Aantal stakeholder = aantal belangen


Initiële componenten


Stakeholders and interests

• Onderwijsinstituten: TU Delft – kennis– onderzoek

• Building companies: 10 partners– kennis, – nieuwe opdrachten– uitstraling

• Suppliers: 30 industries– verkoop

• Local governments: Rotterdam– prestige


Conceptuele ideeën

• Overvloed aan ideeën• Selectie criteria• Technische haalbaarheid• Sociale haalbaarheid• Vooroordelen (hout?)• Impact van de innovatie• Niet te veel in een keer willen

As built situation 2012


Technical evaluation Transition traditional to IDF mindset

• Partner Unica used to measure bathrooms. Not necessary anymore.

• Partner MdR was confronted with another steel building sequence.

• Partner VDM had calculated 1500 KG for the bathroom. This turned out to be 4000 KG, leading to many unexpected adaptations.

• The Solarlux façade was not adapted for housing. • The FAAY electrical wall channels were not tuned with the

timber building structure of VDM.

1


• Insufficient attention for flexibility, resulting in problems in electrical installation.

• Flexibility lacked between floors and walls by partner Unica. • The electricity channels in the floor not properly produced. • The drawings of FAAY came too late.• FAAY refused flexible wiring in the ceiling. • Electric wiring in the façade by VDM became unattainable by

the outside ceramic cladding.• Holes for toilets were not realised in the factory but on the

spot.

Technical evaluation 2


• The screws for mounting inner walls to floor were too long.• Integration partner Niko (Home control) and Itho

(Autotemp) turned out to be impossible, because of intellectual property.

• A decentralised ventilation system of Renson per room, was taken at the last moment

• The architecture of the installation space had to be changed dramatically at the last moment and improvised.

• Partner Unica was too late with detailing and drawing result inefficient use of space.



• Rainwater drainage was forgotten.• Partner Icopal ordered insufficient materials. Improvisation

is necessary. • Partner VDM changes drawings, made by TU Delft. Partner

Justimax had to draw the cladding a second time.• The holes in the ceramic tiles of partner Mosa were

wrongly drilled. 120 m2 has to be redone. • Obsolete tiles could be returned to Mosa for recycling. But

the tiles went to a common waste processor. • Consoles for the solar protection system of partner Renson

came too late. Causing extra hiring of aerial platform.



• The edge of the roof is not realized according to drawings, resulting in improvisation.

• Inaccurate connection between the inner walls on the structure of VDM were done by forbidden PUR.

• The ceiling was made seamless although industrial seams were acceptable.

• Materials as the floor made installation dangerous and troublesome.



Conclusions

• A step into sustainable building practice • For cooperation between companies and universities is a

challenge.• It is difficult to involve companies in futuristic developments. • The strategy to build a complete house turned out to be

effective. All parties participated with a great motivation. • The project disturbs the primary process of the companies.• Parties are experienced better results. • The change of project leaders at TU Delft gave instability. • Necessary permission next steps of finance determined

further possibilities.

Conclusions

• Difficult to plan a project in changing. • Experimenting and building are no friends. • Difficult to mobilize knowledge at the university and to link it

to practical experience of companies. • The culture at the university did not contributed to the

project. However the guts and perseverance happen to be present in the chair holder Mick Eekhout.

• Politics form an important success factor. Not only the product, but also the context is important.

• Concept House Village might be a useful platform just as Booosting and Barba House.
