Precedent Studies Hammarby Sjostad, Stockholm: Hammarby Sjöstad is Stockholm s biggest urban development project for many years. The area s location as a natural continuation of Stockholm s inner city has helped shape the infrastructure, planning and design of the buildings. The City of Stockholm s environmental goals for Hammarby Sjöstad: - Land usage: sanitary redevelopment, reuse and transformation of old brownfield sites into attractive residential areas with beautiful parks and green public spaces. - Transportation: fast, attractive public transport, combined with carpool and beautiful cycle paths, in order to reduce private car usage. - Building materials: healthy, dry and environmentally sound. - Energy: renewable fuels, biogas products and reuse of waste heat coupled with efficient energy consumption in buildings. - Water & sewage: as clean and efficient as possible both input and output with the aid of new technology for water saving and sewage treatment. - Waste: thoroughly sorted in practical systems, with material and energy recycling maximised wherever possible.

Musée du quai Branly: The Museum du quai Branly opened in 2006, and is the newest of the major museums in Paris. It received 1.3 million visitors in 2013. It is both a museum and research centre. The Musee du quai Branly is located in the 7th arrondissement of Paris, on the left bank of the Seine, close to the Eiffel Tower and the Pont de l'alma. The museum complex has four buildings, occupying 30,000 square meters, which, along with the garden, cost 233 million Euros to construct. The buildings: It's most unusual feature is the green wall, or wall of vegetation, composed of living plants, on the north side of the building, facing the Seine. Gardens: The "green wall" of the Branly building is made up of living plants a winding path in the north garden of the Quai Branly museum. The glass wall blocks the noise of traffic on the quai. The gardens were designed by landscape architect Gilles Clement, They were designed to be the exact opposite of a traditional French formal garden; there was no fence, no lawn, no gates, no monumental stairway; instead, Clement composed a tapestry of small gardens, with streams, hills, pools, and groves, using the native French plants and imported plants accustomed to the Paris climate. The gardens contain 169 trees and 72,000 plants On the north side, facing the street along the Seine, the garden is protected by a high double wall of plate glass, which blocks most of the sound from the street. The gardens on the north side practically hide the museum building. Instead of straight paths and a long axis to the entrance, the paths wound through the gardens, with no apparent destination. A notable feature of the Museum garden is the green wall, or wall of vegetation, created by botanist Patrick Blanc. The living wall of greenery covers 800 square meters of the facades of the museum, and 150 square meters of the interior walls. It includes 15,000 plants from 150 different varieties, coming from Japan, China, the Americas and Central Europe. Lomholt, I. (2014, March 6). Musée du quai Branly : Architecture.

Flood Risk: The Canal basin would act as a collection point to reduce the likelihood of the water level rising excessively in short period of time. The canal would also alleviate flooding risk by permitting the release of waters through the lock gates downstream. The main access routes are raised well above the canal basin and flood risk height ensuring safe escape and access routes The majority of the development and access to it are designed so that they are at least 600mm above the design flood level Surface Water runoff: Permeable paving to allow infiltration Use native plants with root systems developed to absorb more water, such as Willows and Alder. Rainwater harvesting can be used to store water in the basement areas of building (WC flushing, garden watering, sprinkler systems etc) Green roofs to reduce water runoff. The use of gravel areas around the trees and use of permeable paving to allow infiltration of rain water into the ground Rainwater: 25%-50% will be either green roofs or water harvesting. Heat Island: Shaded public spaces and footpaths (Roof overhangs, trees, pergolas, canopies, etc) Sun-shading devices for southern elevation towards the basin, using verandas and balconies. Green roofs and vegetable walls Cool area around the canal basin provides cooling effect and the access points enable air-flow throughout the development Tinted glass and refective surfaces combined with the correct size and positioning of windows. Public spaces and footpaths are shaded (Roof overhangs, trees, pergolas, canopies, etc) Open water and fountains in public spaces, cascades, plus the cooling effect of the canal basin. Pavement and wall surfaces have low absorption of heat and increased solar reflectivity Passive urban design strategies: Site layout/orientation Accommodation faces both south and east sunlight, high structures overshadow mostly retail units. The balconies/verandas on southern elevation allow the low angle rays of the sun to reach the building in winter See above other strategies for cooling in summer. Energy efficiency: Passive solar design with habitable spaces benefiting from the southern aspect. Maximising the thermal efficiency of building envelopes Thermal mass and the use of external insulation methods Insulation Air tightness, and the use of double flux air exchangers Avoidance of cold bridging Urban and Architectural Sustainability Maximising the thermal efficiency of building envelopes Thermal mass and the use of external insulation methods Insulation Air tightness, and the use of double flux air exchangers Avoidance of cold bridging Minimising use of energy in the buildings Natural illumination and ventilation, etc High risk areas of temperature extremes are modified by water features in the summer and glass walls in the winter Use of light wells and light tubes. Onsite renewable: LZC technologies Solar Photovoltaic supplying electric to the national grid to offset building consumption at peak times Solar panel/thermal water heating Reversible air/air heat pumps to provide both cooling and heating. Biomass fuelled heating or ground or water source (canal basin) heat pump Total site energy produced by Low or Zero Carbon energy technologies will be of: At least 25% Future Renewables: Waste heat produced by retail units/restaurantscan be used as heat source for water heating, or space heating Other sources of biomass/bioenergy Thermochemical solar power Use of waste in a biodigester to provide methane gas. Wind-tunnel effect and weather resilience: Avoid long narrow and straight gaps along the direction of prevailing winds Non-continuous facades (setbacks, pocket spaces, corner spaces, recessions, etc) Podium with setbacks can prevent window downwashing to pedestrian spaces on ground floor Setbacks on high buildings Use of trees and shrubs to shelter and protect from prevailing winds, particularly for building gaps or entrances. Recessed door ways and entrances. Minimse number of doorways on exposed elevations, and provide alternative access points. Ensure that entrances do not create their own funnel effect through the use of double doors, or rotating doorways. Landscaping: Mix of hard and soft landscaping with native species of trees and shrubs Facilitate the presence of wild life with the canal basin providing an attraction for water birds. The green area will connect between the buildings to existing green areas in adjacent developments. Water features throughout the development provide links with the heritage of the canal basin The canal can be stocked with fish to encourage angling. Trees and shrubs can provide nesting places and food for birds.
