summary: the cooperation between two young danish practices sea and effekt proved to be highly successful with their much-praised winning design for the new building of the estonian academy of arts. while developing the project (which will enter construction phase in 2010) the teams are simultaneously actively participating in international competitions in estonia and other countries as well. below is one of their recent competition entries, the subject being the new town hall of tallinn.
the building would have created an iconic, 65 meters tall landmark in the skyline of tallinn. similarly to the eaa, the town hall is pushed into heights, a concept which in this case did not bring much success. the jury thought the building to be too tall and out of scale, furthermore, the pyramid-shape was considered functionally and logistically too complicated. full description will follow after a short intro in estonian.
eka uue maja autorid - taani noored arhitektid büroodest sea ja effekt - on pärast võidukat eka konkurssi end eestiga üha enam sidunud ning võtnud osa ka raekoja ning pärdi kontserdimaja konkurssidest. suuremat edu nad küll saavutanud pole, kuid vähemalt on töödega pakutud päris põnevaid lahendusi, mistõttu saavad need siingi esitletud.
taanlaste nägemus tallinna uuest raekojast lähtub soovist luua ikooniline maamärk, mis saavutatakse sarnaselt eka-ga vägagi riskantselt kõrgusse pürgides. hoone vorm lähtub lihtsast horisontaalse mahuga kastist, millest tuletatud kaks torni - «twin peaks» - raamivad vaateid linnahallilt vanalinnale ja vastupidi ning moodustavad nende vahele puutepunktid maapinnaga, läbi mille hoone mastaapsus oluliselt väheneb. jääb küll selgusetuks, kas hoone saanuks siis ronitavaks või mitte.
žürii raportis ei leidu projekti kohta ühtegi head sõna. kavandatud hoone oli otsustajate hinnangul mõõtkavast väljas ja liiga kõrge (65 meetrit! - see on meetri võrra kõrgem kui raekoda vanalinnas), püramiidjat vormi peeti sellise paljukorruselise hoone puhul funktsionaalselt ja logistiliselt liialt komplitseerituks, lisaks poldud rahul fassaadiga, mis vaid teeskleb olevat kandev - kusjuures vastupidiselt autorite eka projektiga. kriitikat sai ka ulatuslik klaasfassaadide kasutamine, mis on säästlikkust taotlevale hoonele sobimatu. mäletatavasti kummitas (või kummitab siiani?) sama probleem ka eka-t.
probleemidele vaatamata on tegemist ülimalt efektse tööga, mis - kui vaadata vaid vormi - oleks tallinna siluetile palju juurde andnud. unesco virina saatel, muidugi.

the historical town hall
the original town hall building located in the heart of tallinn has an impressive history of over 700 years of architectural changes and improvements. originally it was a low rise building slowly growing in size and appearance over the centuries. the tower was added in the 17th century strengthening the iconic appearance of the building in the growing cityscape. thereby the typology changed into a building that does two equally important things. it has a body which relates to the streets and urban spaces and at the same time the tower rises to become an urban landmark that can be seen from the rest of the city.
a new landmark
we propose to create a new town hall that combines these qualities in an integrated design. the new building combines the need for viable urban spaces as well as iconic qualities branding the city. it will be an important landmark that both represent the power structure and act as a guiding icon in tallinn’s new cityscape. it’s both rational and humanistic at the same time. it combines the need for a sustainable and energy efficient building with the need for a sculptural landmark with beautiful experiences.
the twin peaks
the shape of the twin peaks is created by a simple gesture. two corners are lifted into towers and two corners touch the ground. it creates a unique triangulated building that offers a variety of experiences depending on where you see it from. the shape gives experiences in both micro and macro scale. on one hand the building becomes an iconic landmark that can be identified from afar in the skyline and along the coastline. at the same time it also slopes down to the ground connecting to the surrounding urban spaces in a dialogue with the context and human scale.
a sustainable building
the new town hall positioned outside the old city centre is a cornerstone in the transformation of the harbour front. at the same time in close dialogue with the cityscape and the landscape. the scale of the site, context and programme gives the possibility of a larger, compact and sustainable building. a building that is easily accessible by car, public transportation or by foot from the old city centre. we propose a compact building typology opened by large atriums providing energy efficiency as well as good daylight conditions and indoor climate.
sustainable design
integrated design
a sustainable and healthy building with a minimum of the energy consumption and co² emissions can be achieved through an integrated design process. the integrated design process includes multidisciplinary collaboration and workshops with participation of key stakeholders, design professionals and the users. in the design process evaluation of design variables are investigated with regard to architecture, functionality, and environmental issues such as resources, indoor climate and energy consumption.
energy optimization
when it comes to energy issues, the close relation between the thermal and visual comfort, indoor air quality and the energy required for operating the building is the key to a successful design, where sustainability is embedded in the design. the indoor climate also has direct impact on the quality of life, comfort, health and well being of the occupants of a building. the building has been designed with focus on reducing the energy demand for heating, lighting and ventilation by a compact building design, usage of passive solar gains, daylight and efficient technologies. furthermore it is possible to implement energy producing components such of solar cells or hot water solar collectors.
façade engineering
the building envelope and transparent areas are designed and engineered in order to create a well insulated and air tight boundary to the surrounding climate. the façade scheme, where glazed and blinded areas can be randomly placed in between the overall façade grid, allows enhanced modelling of the façade properties in order to create the optimal balance between daylight utilization, the prevention of overheating by solar irradiation, and insulation. hence it is possible to optimise the façade properties in accordance to the orientation and the demand, expatiations and usage of the different rooms behind the façade.
dailight utilization and artificial lighting
the façades are modelled in order to create high daylight utilization and distribution of daylight to the deeper parts of the building. in connection with the use of an effective daylight controlled artificial lightning system this will effectively reduce the significant energy consumption for electrical lighting.
climate regulation
high thermal mass and effective climate regulations systems and strategies reduce energy consumption and at the same time insures a good indoor climate. ventilation and climate regulation are performed by system specifically designed to the different parts of the building. atriums and large areas are ventilated by natural ventilation. during summer where solar irradiation and rising temperatures demands ventilation, natural ventilation insures an effective ventilation with a minimum of electrical energy consumption. in office areas and other heavily populated areas mechanical ventilation with an effective heat recovery creates a good thermal and atmospherics environment without creating a large energy demand heating of supply air.
