Energy Flows & Energy Future of Lloyd Crossing Sustainable Design Plan

The Lloyd Crossing Sustainable Urban Design Plan is a sustainable strategies integrates multiple energy, water, and habitat. The Plan’s energy vision for Lloyd Crossing in the year 2050 is a vital, attractive urban community that has achieved a neutral carbon balance by implementing a series of incremental energy efficiency strategies, both on-site and off-site. These strategies work together to reduce the neighborhood’s reliance on non-renewable sources of power, increase its utilization of available solar energy, and generate cost savings that can be reinvested in other areas.

 Renewable energy
As the study area is built out, building efficiency will generate increasingly significant savings. Photovoltaic and wind systems will not only save money, but will also present the district's sustainable identity to the larger community. A number of renewable-energy strategies are planned:
10 megawatts of photovoltaic (PV) capacity are planned through rooftop PV, south-facing PV wall cladding, PV window shades for south-facing glazing, and PV arrays lining a 3/4-mile stretch of Sullivan’s Gulch.
1.4 megawatts of wind-turbine capacity are planned through two small (five to ten kilowatt) vertical-axis turbines on the roofs of high-rise office towers and two large (600 kilowatt) horizontal-axis turbines mounted on 60-meter poles.
Biogas will be generated from waste processing in the study area.
The development will purchase wind power for all imported electricity and carbon-offset credits for all imported natural gas.
These images compare the energy-use conditions of the area before development, in 2004, and in 2050 according to code and according to this development plan.

A Sustainable Residential Area - Bo01, Malmö, Sweden

图片
In Malmö, Sweden, a reconstruction project of a former industrial district was initiated known as City of Tomorrow in 2001. The reconstruction of Bo01 developed a sustainable mixed-use residential district focus on sustainable urban development. Malmö taken some active Strategies to sustainable city construction through the three main ways including energy conservation, management of drainage system and Sustainable transportation. 1.Management of drainage system Bo01 created a stormwater management system in order to protection of surrounding seawater quality. Green roofs, vegetated basins, ponds, and surface stormwater transportation system make up the storm- water system at Bo01. Water from downspouts and the stormwater from ground are led through channels to vegetated basins for Filtration and infiltration, finally drained into the sea.   2.Energy conservation Bo01 advocate use the renewable energy technologies such as wind energy, solar energy and geothermal...

Waste Management Technology in Malmö Bo01

图片
In the Bo01, The waste management system was created with the aim to develop a system that minimises the amount of waste, makes reuse and recycling possible and enables the use of waste and sewage as an energy source. Having waste separation units close to home is an important part of the planning of the area. The inhabitants usually have a separation room in their house or close by, making it easy for them to sort paper and packaging materials. Organic kitchen waste is ground at the residence and collected in underground vaults (Figure 1), from which it is pumped to an anaerobic digestion chamber. The biological treatment of this slurry by bacteria creates biogas (methane), which is drawn off and used to power public buses or used to generate heat and electricity. Figure 1. Food waste disposer the organic waste are grinded and disposed in separate pipes to a collector tank under ground. Similarly, the non-organic waste is deposited in the vacuum tubes located in the res...

Growing Sustainable Food Systems in Growing City

图片
The University of the District of Columbia (UDC) proposed a idea of creating sustainable urban food system aim to solve a city challenged with high levels of poverty, obesity, and population growth. From cultivation, preparation, and distribution to food waste management, this project will provides food security for city residents but does not compromise Earth's systems or the ability of our species to survive. UDC created a rooftop farm in the campus, which is the largest rooftop farm in the city to plant the vegetable and flowers. Beyond the campus, the Firebird Farm is working for the sustainable agri-experiments. Here UDC is experimenting with a wide selection of crops and techniques to sustainably provide food for a growing city. UDC is not just focused on growing crops on the campus and farm, they also build the “Urban Food Hub” include farms, hydroponics systems, and food preparation facilities in the city,   aim to providing new skills, jobs, and healthy sustainable fo...
