Elioth took part in the call for ideas on the development of the Arstafaltet district on the southern outskirts of Stockholm (Sodermalm). The project is part of an urban environment that saw the birth of Hammarby Sjostad, one of the first European eco-neighborhoods. The aim of this phase was to evaluate the potential of the urban project with regard to the Swedish energy policy (energy production at 50% renewable energy by 2050) and to initiate a comfort analysis Microclimate of outdoor spaces.
The engineering process was not a “stand alone” analysis, but it was driven threw the project beside the architectural and landscaping decision. We have this way been able to influence the massing and the park three distribution to maximize the solar passive resources and the wind protection. After a first “4 seasons” approach, we went deeper into the wind analysis for mid-seasonal situation where wind can really affect the draft temperature (Stockholm summer is “naturally comfortable” and winter is too severe to expect comfort). The engineering approach developed during this early phase project has shown the interest for microclimatic design in order to optimize the massing and the outdoor conditions. The typology analysis will help the urban planner in defining some constraints and potential for the future building designers. Despite the northern climate, we have shown that the Swedish target for a ~65% renewable mix is possible locally going beyond the Swedish energy target for 2020 but conditioning some specific investments. One of the major inputs for the project orientation is the opportunity for a new generation low temperature district network.
