A sustainable residential city
- 1. A Sustainable Residential area Submitted by : Team Xochipilli Section C of Civil ‘15 Engineering , planning & architectural appreciation CE 208 Group includes ID : 1510 ( 003,009,010,012,013,014, 015,019,021,028 )
- 2. What is sustainability ? Meets the needs of the present without compromising the ability of future generations to meet their own needs
- 3. Being sustainable makes sense. It can improve health, increase safety, and save money.. Sustainable residential areas can be an effective solution for ensuring sustainability among people
- 10. Top View
- 11. Elevations
- 15. Wheelchair & Bicycle lane
- 18. Sunpathanalysis Maximum sunlight in South East direction, maximum area of photovoltaic cell is provided in that direction
- 19. Windanalysis
- 20. WindofChittagongflowingfrom Southwestdirection Wind rose of Chittagong Wind turbine direction is Adjusted according to the analysis
- 21. Agenda • Minimizing Energy Use and Use Renewable Energy Strategies • Conserving and Protecting Water • Enhance Indoor Environmental Quality • Optimizing Site Potential • Pollution and waste reduction measures, and the enabling of re-use and recycling
- 22. Main Features
- 23. Wind turbine electricity Wind turns the propeller like blades of a turbine around a rotor, which spins a generator , which creates electricity.
- 24. We provided 3 wind turbines of 8 ft blade length
- 25. Blade length, l = 2.44 m Wind speed, v = 80 m/sec ( Chittagong , from BNBC 2015 ) Air density, ρ = 1.23 kg/m3 Power Coefficient, Cp = 0.4. Wind energy calculation
- 26. A = πr2 =18.70 Pavail = .5 ρAv3 Cp .5x1.23x18.70x803 x.4 = 2.36 MW
- 27. Photovoltaic glass for electricity generation Enables the conversion of sun light into electricity. To do so, the glass incorporates transparent semiconductor- based photovoltaic cells , which are also known as solar cells. The cells are sandwiched between two sheets of glass
- 28. Total 9140 ft2 Of photovolataic glass used
- 29. Calculation of the solar PV energy output of our photovoltaic system
- 30. Rain water harvesting Rainwater harvesting is a process or technique of collecting, filtering, storing and using rainwater for various purposes. We are storing rainwater for emergency purposes
- 31. Using Biogas Biogas is produced through the processing of various types of organic waste. It is a renewable and environmentally friendly fuel
- 32. Waste produced by single person = . 40 waste/day/kg Biogas from waste = . 028 m3 / kg waste No of people in a floor = 25 approx. So, total no of people in a building = 25x18= 450 So, waste produced by total people = . 40 x 450 = 180 kg/day Total biogas produced by people = 0.028 x 180 = 5.04 in3 Biogas calculation
- 33. We know , 1m3 = 19 mega joules Biogas calculation So 5.04 m3 = 95.76 mega joules Or 26.6 kwh !
- 34. Under roof greenhouse A greenhouse is a structure with a glass or plastic roof and frequently glass or plastic walls . Its roof and sides have to allow light to penetrate.
- 35. We used the last floor as green house These pv glasses also harness electricity
- 36. Electricity generating stairs and corridors Vibrational energy harvesting using piezoelectric tiles in stairways & corridors subjected to human traffic & use that power in lighting staircases and corridors
- 37. Electricity generation from roads & sidewalks
- 38. Electricity generation from roads & sidewalks
- 40. Separate lanes on the residential zone road Separate lanes for bicycle and wheelchair will be provided with sufficient spaces
- 41. Green facades Green facade is created by growing climbing plants up and across the facade of a building, either from plants grown in garden beds at its base, or by container planting installed at different levels across the building.
