Abstract

The concept of ecological building is not clear. The concept, which belongs to thematic context of sustainable development, is difficult to understand because it combines two individual concepts which originate from two different sciences. The word ecology implies to organism's interaction mechanisms and to ecosystem dynamics, whereas the word building implies to architecture, artifacts and semantics. In ecological building the whole interaction dynamics has to be reassessed. The interaction between artifacts and environment conveys the same principles as the interaction between organism and ecosystem. Buildings and towns have the same kind of genotypic and phenotypic features as organisms have. Genotypic features can be paralleled to materialistic, atomistic, features. Phenotypic features result from the interaction process, in which the modifying environment consists of culture, local conditions, style and time.

Localism is crucial in the context of ecological building. Localism is a geographically defined entity, but also it is primarily a process. In this research the connection between ecological building and localism has been examined in two neighbourhood units. Buildings in Rovaniemi (Ounasrinne) and in Mikkeli (Peitsari) built on non-profit and social housing basis were selected. The criticism against the ontology of ecological building is based on the questionnaires and the personal interviews, which were targeted at the tenants of the selected tenements, selected designers, contractors and the board of the real estate companies. In addition, the managing directors of the real estate companies and the representatives of the Finnish Housing Fund and the Ministry of Environment were interviewed. Migration during the entire lifecycle of the tenements, which is an indicator of localism and sustainable development, was researched by analyzing the registers of occupants.

The research revealed that the actors have defined the concept of ecological building in different ways. Most often ecological building is related to material features. Ecological material is not automatically related to high quality material and local materials are not the first priority. The responsibilities are contradictory in the implementation of ecological building. The primary presumption seems to be that the state is responsible for the implementation. Environmental consciousness and ecological building have positive status. In the future the mode of building, which is assumed to be ecological, will increase and environmentalism is regarded as a benefit in business competition (contracting and designing). The research also revealed that the need for change in values, which is usually connected to the thematic of ecological building and the sustainable development, is groundless; the actors think that the nature as such conveys intrinsic value. Instead, ecological issues should be an interest, which affects the decisions made during the process. The tools, which are used in the process, should more effectively support the implementation of ecological building. Free will is not sufficient any more.

The research revealed that the periods of occupancy are short in the examined tenements and we can talk about new kind of nomadism. In these neighbourhood units lifelong occupancy is not realism. The renovations, which have been designed according to the tenant's will, must be revaluated, because the median period of occupancy is approximately 1½-2 years. Technical renovations did not lengthen the periods of occupancy in Ounasrinne, vice versa. In neighbourhood units attention must be paid to the tenements; the support for housing should be defined locally according to the actual tenement sizes.

Tiivistelmä

Tutkimuksessa ekologisen rakentamisen ja paikallisuuden välistä yhteyttä on tutkittu kahdessa lähiössä. Tutkimukseen mukaan valittiin yleishyödyllisen rakennuttamisen ja sosiaalisen asuntotuotannon kohteita Rovaniemen Ounasrinteeltä ja Mikkelin Peitsarista. Ekologisen rakentamisen ontologian kritiikki perustuu kysely- ja haastattelututkimukseen. Paikallisuutta ja kestävän kehityksen tematiikkaa indikoivaa muuttamista vuokratalojen koko elinkaaren aikana tutkittiin talokirjojen avulla.

Tutkimus paljasti, että toimijoilla on toisistaan poikkeava käsitys ekologisen rakentamisen sisällöstä. Useimmiten ekologisuus liitetään materiaalin ominaisuuksiin. Ekologista materiaalia ei mielletä automaattisesti laadukkaaksi eikä paikallisia materiaaleja priorisoida. Ekologisen rakentamisen implementoinnissa vastuukysymykset ovat ristiriitaiset. Ensisijaisesti edellytetään, että valtio on vastuussa ekologisten tekijöiden implementoinnista. Ympäristötietoisuus ja ekorakentaminen koetaan myönteisesti. Tulevaisuudessa ns. ekologiseksi rakentamisen oletetaan lisääntyvän ja ympäristötietoisuus on kilpailuetu liiketoiminnassa (urakointi ja suunnittelu).Tutkimus paljasti, että kestävän kehityksen tematiikkaan ja ekologiseen rakentamiseen liitetty vaatimus arvomuutoksesta on perusteeton; toimijatahot arvostavat luontoa sen itsensä vuoksi. Sen sijaan ekologisuudesta pitäisi tulla intressi, joka ohjaa prosessin aikana tehtäviä päätöksiä. Prosessin hallinnassa käytettyjen työkalujen on selkeämmin tuettava ekologisen rakentamisen implementointia.

Tutkimus osoitti, että tutkituissa vuokrataloissa asutaan lyhyitä aikoja ja voidaankin puhua uudesta nomadismista. Näissä lähiöissä elämänkaariasuminen ei ole realismia. Asukkaiden toiveiden mukaiset korjaukset tulevat myös uudelleen arvioitaviksi, koska asumisaikojen mediaani on 1½-2 vuotta. Tekniset korjaukset eivät muuttaneet asumisaikoja Ounasrinteellä; päinvastoin. Lähiöissä tuleekin huomioida asuntojakauma asumistukia määritettäessä.
