Provisions to use newater
Use of greywater (from i.e. handwash basin and showers) to flush WC
Use of aerated showers
ESD for water efficiency

8. ESD for environmental air quality
Low VOC paints, carpets and furniture
Refrigerant leak detection system
Mould and fungi eliminating liquid compound
Plants at work place
ESD for environmental air quality

9. Bamboo house Occupant well being-thermal comfort Visual comfort
Air quality
Thermal mass
Light shelves
Natural ventilation
Choice of material
Operational energy-energy demand
Bamboo house

10. Occupant well being-thermal comfort
Thermal comfort ranges for different people
Preferred temperature can be plotted to determine the thermal range of comfort
Occupant well being-thermal comfort

11. Visual comfort General guidelines 100 lux: corridors 300 lux: reading
2000 lux: computers
Visual comfort

12. Naturally ventilated areas showed low readings of CO2-limit 1000ppm
Air quality

13. As a buffer to the swings in air temperature-moderates the differences
It keeps the house cool during the day but slightly warm the house at night time
Thermal mass

14. East and west facing openings will only get reflected direct lights from degrees from horizontal=before 0900 and after 1700
Only diffused light will enter during the middle part of the day and windows on the north and south side
Light shelves

15. Local topography, vegetation and surrounding buildings have an effect on the wind speed and directions-critical factor in the effective operation for natural ventilation
Natural ventilation

16. Choice of material Operational energy-energy demand
Bamboo-readily available, fast growing minimal environmental impact
Choice of material Operational energy-energy demand

17. United Christian College

18. High connectivity and interaction of indoor and outdoor spaces (eco-path, communal courtyards, outdoor classroom, green roof, atrium green wall)
Low carbon environment-facilitating and utilization of natural ventilation

19. Grey water from swimming pool for cleansing of outdoor paved areas
Composting bin at the ecopath to turn waste into fertilizer
Green terraces to reduce heat gain and improve the air quality
No or low VOC finishing materials in the indoor applications

20. Passive cooling to reduce carbon footprint
Atriums with top vents for stack effect
Cross ventilation enhanced by wind catcher and wing walls
Maximise the use of daylighting

22. Council House 2 (CH2)

23. Sustainable design and energy performance
POE result-rated highly in thermal comfort, daylighting and air quality
Personal control at workstations

24. Passive design techniques- duration of opening and displacement of air
Concrete ceiling absorbs heat during the day and release heat at night
Sunshading to minimize heat gain and filter light penetration

27. Green slope-3rd prize winner

30. Filtered treated and stored Hot water warmed by solar
Biological treatment
Inflow-overflow
Combined greywater and rainwater utilization system with underground tanks
Water recycling-water from green roof and lake+ underground water pumped through a well
Filtered treated and stored
Hot water warmed by solar
Secondary water recycling-rainwater + runoff stored in greywater tank for treatment
Used for flushing toilets and watering greens

31. The given climatic conditions

33. Solar panels for glazing and energy generation
Passive solar design aimed to maintain interior thermal comfort and reduce requirements for active heating and cooling-turbines, cross ventilatilation, shading, jalousie on exterior walls, ventilated green atrium space( refreshing the air and reducing noise)

34. examples

36. Green creepers on the east-west façade shading the interior spaces from direct sunlight
Integrated filtering system for treatment of greywater, blackwater and stormwater
Living machine to produce portable water-wastewater treatment technology-series of tanks+ vegetation + organisms= bioremediation and ecological based components
