DESCRIPTION

Architectural - Social - Technical Task: To generate proposal for a multi functional urban block for Älvstranden Utveckling AB. The project has to widen environmental improvements by an interdisciplinary co-operation between architects and engineers. Site: At the edge of a dense living urban area: between an urban back side, the old industrial harbour of Göteborg, Norra Masthugget and surrounded by parking lots, car lanes and highway dissociating the Göta älv river from the city. The developer got the opportunity by the municipality to catalyst an attractive future. Project: From a deep understanding of the urban and social needs, we created new standards of living in a dense urban community. A student community accommodates with mixed urban facilities: a library, a gym and a pub and a restaurant. Architect students: Charlotte Lartigue, Daniel Spence, Kristina Sahleström Engineer students: Elefterios Zacharachis, Henrik Bengtsson, Pär Johansson Professor: Michael Eden

Step 3, 2050

ReConnecting identity with the location

Extending the city grid and re-connecting the city with the harbour. See the building as “spark” for the evolution of the area and as a sustainable precinct, extending the green corridors in the city.Reflection of negative space in the building adjacent forms the build-ing structure for ultimate sun gain. A building able to function autonomously in a hostile climate and adapt and instigate a sustainable development of Södra Älvstranden.

“Art”+”Function”=”Spark”

The design takes into consideration the aim of the city to be “sustainable” and car free by 2050. It sees the evolution step by step, taking into consideration and making room for each new demand. It incorporates a new way of viewing “function” and “art” uniting the two to define the harbour front and bringing the city closer to the water. By first establishing a visual connection, it makes the physical connection easier to follow through. Throughout the design process, architecture, social questions and technical innovations have been in symbiosis.

Communal waterfront, energy landmark.

Creating a visual connection between the city and the waterfront as well as a very defined sense of place at the water front’s “energy boulevard” where tidal and wind power is used for the building and the developing area.

Architectural response, shaping the building

1- “site” two fronts:

A front open with view on the harbor, north light and noises from high traffic

A second front hostile, with shadows of neighbourd

2- Facades responde to the environmental constraints

3- Cuts througth to bring in light, to create space for green-houses and creating pockets of mini biospheres. .

3 Dynamic Living System

-The building as a self-supporting student community.

- The building as an exhibition: environmental systems exposed wherever possible.

- Flexibility to use rooms as hostel/rented room in summer.

- Rooms divided into small “community centres”, where one kitchen is shared between 2-4 in dividuals. Larger communal spaces, together with the green house area, cater for each floor and create oportunity for informal meeting and encourage multicultural mixing.

ercialFirst floor as an interactive space between public ground and private student rooms above.

The “voids” allow light to penetrate all spaces, also creating intimate commu-nal public spaces in conjunction with a pedestrian street.

The design layout of the residential plans is flexible, allowing for future changes. It aims toward a more communal living with the benefit of saving ener-gy and working against the isolated lifestyle inner city people live today, where depression is common. By focusing on creating environments where “accidental” meetings can occur, this problem would diminish, includ-ing a better mix and understanding among people of their fellow neigh-bours.Circulation through the greenhouse avoids the creation of corridors.

Construction Details

Ecologically sensitive application of materials Use of local and low-embodied energy materials (eg. timber shutters): recycled timbers, recycled shipyard steel, rammed earth, recycled insulation and south facade windows of EFTE (Ethylene-TetraFluoroEthylene Copolymer). The weight of the panels is 1 % compared to glass and hence require less structure to hold it and allows for less consuming transport. The thermal and translu-cent properties are similar to those of glass. Between the sheets of EFTE there is argon or vac-uum that gives a higher thermal resistance.

The facades are designed to meet different envi-ronmental constraints and give a richness to the architectural expression.

Waste treatmentAn integrated recycling station is found in each stairwell on the first floor. Tubes lead to the waste room on the ground floor where the waste is gathered and transported to a recycling facility. The compost is dried so that the organic mate-rial does not weigh as much as originally, which equates to a 75 % decrease in volume and mass, and is distributed in the greenhouse. This means fewer and smaller transports, from 52 to two transports annually. The system gives off heat to the room where it is situated. The wet material is ground and dries in an air stream of 20°C before it is mixed with dry material and transported to the storage chamber. The energy consumption is ap-proximately 6 500 kWh/year (0,75 kW), and the amount of biogas that can be extracted from the biomass is 45 000 kWh/year.

Water Awareness

The water system will be equipped with individual consumption measurements and low-flow tapping systems. These efficient systems can reduce the water consumption by 20 % each, which means a total decrease by 36 % compared to common buildings. Separated toilet system: urine used as fertiliser, solids taken to sewerage plant and used for biogas extraction: very little water consumed in the process.

Grey water recycle to reuse sink/shower water for toilets. dilution from rain water tank

nutrient free soil with water purifying plants

lava (bio film over rock)

rapid gravity sand filter

Complex Integration of Systems

-An integrated heating, ventilation and energy system us-ing new technologies such as wind balloons, tidal energy and energy generating floor systems, together with more conventional systems such as solar panels, river heat pump, heat exchanger between incoming and outgoing air, and where all rest heat in outgoing air is used to heat the green house.-Taking advantage of nearby water for heating/cooling.

-A heat pump collects heat from the river and transfers it into the floor heating system. The temperature supplied from the heat pump is lower than in a conventional hydronic heating system which makes the efficiency of the heat pump higher. When heat from the solar panels is available it will be used for the floor heating system.

Climate protectionareful investigation regarding wind and solar conditions on the location has been a major part of the planning process with an aim towards the lowest possible energy consumption. The greenhouses that are located on the south side of the building are designed for providing the best conditions for cultivation. Larger window areas towards the south than to the north decrease the demand for heating and artificial lighting in the building.The building is self-sufficient in regards to heating and warm water during a large part of the year. When the solar radiation is not enough a heat pump that collects heat from the nearby river, Göta Älv, will provide for the remaining part of heat. Electric energy for facility electricity is provided by high altitude wind balloons and tidal power plants that are located along the river.The domestic heating is provided by an efficient low temperature floor heating system. This system requires lower temperature in the water circuit (30°C/26°C) and therefore less energy is needed to provide the required heating, in-creasing the performance of the heat pump. Excess energy is transferred to an accumulator tank and stored for future need.The ventilation system will make it possible to filter out substances present in the outdoor air. The exhaust air flows through the greenhouses which heat them during the cold part of the year and cool them during hot sunny days, by this solution the greenhouses can be used all year long.The roof is covered by 1 000 m2 of solar panels that provide the basic supply of heat for domestic hot water (60°C) and hot water to the public areas.A large heat mass in the structure of the building store heat from daytime and releases it during night time. This means that the available power for heating and cooling will decrease since the peak demands will become smaller.
