Green Zipper. Nordic Build - Norway

Transcription

1 Nordic Build - Norway

2 In short If a tall building is a city in the sky, it needs gardens just as a city needs parks. A green vertical zipper will bind a garden together with the public realm. It seeks to create a sense of community that transforms our experience of the workplace. That may mean breaking down a large floor space into smaller groups to provide a feeling of identity and a social focus. The zipper suggests open, flexible working environments in which communication can flourish. More natural light can enrich a space. It can change our perceptions it can lift our spirits. Environmentally, it will work as a lung, driving natural ventilation systems to reduce energy needs.

3 Idéa Existing situation with the current slap in the structure By extending this, a big atrium is created. Exosceleton is added as a selfbaring structure. This will open for a dobbel-ply facade...and a possibillity to add floors indepentently from existing structure

4 Integration The proposal seek to integrate the public realm of the city through the flow of the new central station. Thus, the flow finds a new puplic atraction in the space of the zipper, with puplic functions as shopping, restaurant and a central station square. The new central station. Construction will start in 2014 with an estimated completion date of

5 An addition of greenery within the zipper will function as a filter, rinsing the air, when traveling through the space On top, a Green Garden is proposed. This will, besides extra office space, function as a green energy-producing battery created from air, sun wind, and greenery. The new space will let more daylight penetrate deep into the building...and give an improved view over the city The visual green image of the building will comute an enviromental vision to the city

17 Green Garden Bio-facade Biogass Heating CO2 Biomass Fuel cell Green Garden Warm water Electricity Central heating Biomass/biogass Electricity Heat Heat Holdingtanks in the Green Garden At the top of the building a Green Garden is located. This serves as the building s green battery. This is a laboratory for present and future energy production, created through bioreactor facades. The facades consists of micro algae which exposed for sunlight to produce green energy. The energizing algae facade uses the latest findings in energy and environmental technologies. Combined with geothermal and solar thermal heating it creates a holistic concept of regenerative energy. Microalgae: Smart energy bundle Energy production with algae is a new and equally exciting field of energy and environmental technology. Microalgae are tiny plants - mostly no larger than bacteria - which use sunlight to generate nutrients nitrogen and phosphorus biomass alongside with CO2 The algae are grown in the intelligent bioreactor façade, through photosynthesis transforming lower energy materials into energy-rich matter. Under optimal conditions, they divide twice a day, from which new organisms arise for energy. The proverbial bundle of energy is friendly to producers of renewable energy resources. In a biogas plant, located in the Green Garden, the harvested biomass, methane is obtained and then dried. This matter can then be used as fuel gas or the operation of engines. Simultaneously heat is generated, which can be used in the building. In short, CO2 storage on the Biomass, methane is extracted from the biomass as a renewable energy source, simultaneously heat is produced, which can be used in the building. Finally the bioreactors are used to control 1)light and shade, 2) the heat and cold protection, 3) and the sound insulation. Within the buiding, the facade runs through the final crater of the Green Zipper, and works as a bioreactor. Plate-shaped panels are placed in the cavity that is necessary for circulating the cultivation of algae culture medium. The panels are one story high and 60 centimeters wide and connected together to form clusters, and powered by separate circuits. The necessary supply lines runs alongside the edges of each cluster, integrated in a 30 cm wide space between the outer wall and the bioreactor. The water cycle The algae are continuously supplied with liquid nutrients and CO2. A constant mixing of the water in the collector is done by large air bubbles. Using solar power, the algae then multiply until they are ultimately forwarded to the harvest in the technology space in top of the building (Green Garden). The micro-algae can be separated from the culture medium, resulting in a thick porridge made from algae biomass. The culture medium is fed back into the circuit and flows into a holding tank, where it can be stored at five degrees for a few days. For the recovery of biogas, the external micro plants can be used further.

18 A facade, many tasks At the floor of the Green Garden, an algae-resturant is located (obviously serving algae-related food) Here the visitors can follow the progress of the aenergy-producing cycle, as the facade changes from light green to dark, green. The facade also it serves as sound insulation in the crater of the, and provides shade in bright sunlight. great potential It make sense to use facade bioreactor for regenerative energy, while contributing to minimize CO2 emissions in the modernization of existing buildings, which in addition have an artistic appreciation. Together with the photovoltaic technology, this system could replace solar thermal absorbers for housing intended market. In BG14, the vision is that the replacable panels in the internal facade easily can be replaced by algae-panels, as the technology developes, and thus create a living facade starting from light green, turning dark, harvested and then all over again. A literally green building! Green image for businesses In the area of commercial property the implementation as cold facade for energy production can also function as spandrel panels or sun blinds. The heat can contribute to cold pumps for air conditioning / ventilation of the office space. In this way, companies makes a contribution to reducing CO2 emissions, active and visible to the environment and climate. Green Garden concept Green is not just green Changes depending on dosage of the growth substances sets the color intensity to the bioreactor facade. That means Oslo can sit and watch the future in the production of bioenergy.
