Kulturhus i Älvsjö - lågenergibyggnad i trä

Ringbom, Lars January 2015 (has links)
Bevaransvärda ekar och en stor sten har fått styra utformningen över ett scenrum, mellan landskap och byggnad. Som kontrast till Älvsjömässan är omgivningens inflytande  tydligt på kulturskolan. En plattform möter upp utgången på stationsbyggnaden och fortsätter dess infrastrukturella syfte att ta besökarna över tågspår och stenås.  Materialet är trä med lättbalkar, ekologisk cellulosaisolering och ytskikt av plywoodskivor. De kraftiga men mjukt rundade väggarna ansluter sig både till en organisk och klassisk form  och kan antyda både kolonn och trädstam. De relativt höga våningarna, som succesivt terraseras från söder till norr landar över mässahallen västra fasad - som en markering av sitt värde som kulturinstitution i området. De kraftigt isolerade väggarna fungerar också ljuddämpade - vilket närheten till pendeltågen gör nödvändig.   Byggnaden kan delas in i tre sekvenser: den höga delen med drama- och teatersscen, mellandelen som är ett trapphus med salar och verksamhet, samt cafét som även den har ansluten verksamhet. / Oaks and a large stone has been crusual to the design of the stage space, between landscape and building. In contrast to the Stockholm International Fairs the environment influence is sinificant on the cultural school. A platform meets the end of the station building and continue its infrastructure with a view to taking visitors across railroad tracks. The material is wood with light beams, organic cellulose insulation and the surface layer of plywood. The powerful but smooth rounded walls connect to both an organic and classical form and can indicate both the column and the tree trunk. The relatively high floors, which gradually terra served from south to north lands of exhibition hall western facade - as a highlight of his value as a cultural institution in the area. The heavily insulated walls also serves silenced - as near to the commuter train makes necessary. The building can be divided into three sequences: the high part of drama and theater scene, the middle part is a stairwell with labs and activities, as well as the café, which also has connected business.

Studie av lågenergibyggnader inför projektering av nära-nollenergi förskolor / Study of low energy buildings in preparation of near zero energy preschool projects

Nilsson, Daniel, Hallberg, Vilhelm January 2016 (has links)
Purpose: Production and utilization of buildings contributes immensely to global carbon dioxide emissions. The construction sector today accounts for over a third of global energy use will increase as the world population increases. According to the EU Directive from 2010, all new buildings in EU member countries as of December 31, 2020 are to be classified as near-zero energy buildings (NZEB). The goal is to investigate the various energy-affecting measures of the involved architects, structural engineers and planners that can improve the energy performance of a kindergarten to be closer to near-zero and identify obstacles that make it more difficult to achieve NZEB. Method: The investigation strategies for the project are qualitative methods in the form of semi-structured interviews with architects, planners and ventilation engineers for six different kindergartens. The interviews were conducted by telephone in which the questions were sent in advance to those interviewed. Mail interviews were conducted early on which resulted in either short answers or not answers at all. The energy performance documents of the different kindergartens were analyzed to get information about the different energy performances. Findings: The result does not contain a solution as to what the near-zero energy definition is or how to define it, but is more like guidance concerning what factors you can influence to get closer to near-zero energy for a kindergarten. Recurring problems surfacing in the interviews is that not all the involved roles have been able to influence predetermined choices of shape and space that, among other things, contribute to a limited space for services that planners are having difficulty influencing afterwards. Implications: The result helps contribute to making sure buildings are built in a more energy-efficient way and by such reducing the construction sector's share of the global energy consumption. The building's energy efficiency may not contribute to poor indoor climate in such a way that it affects children's health in a negative manner. This results in a need for careful planning where all parties can contribute with their best energy efficiency solutions without being too limited by the architectural constraints of shape and space. Alternatively, better communication between planners and architects in the earlier stages. Good planning contributes to a better result. Limitations: The result is based on Swedish kindergartens in a Nordic climate and should not be applied in countries without a Nordic climate. The result is not only applicable to kindergartens but is largely applicable to most similar buildings. Contact with more architects, constructional engineers, planners and more kindergartens would have given a better result.
