  3. Thebalitigergroup[Pantheratigrisbalica] Range: Indonesian Island of Bali Average Weight:  Female: 65-80 kg (143 - 176 pounds)  Male: 90-100kg (198 - 221 pounds)Size: Tigers reach up to ten feet in length and weigh 400 to 575 pounds. Diet: All tigers are carnivorous [pigs, deer, antelope, buffalo and other]Cubs Per Litter: (Usually 2-3 cubs) Cubs are born blind and weigh 2-3 pounds.Lifespan: Tigers live for 10-15 YearsOther Information: Smallest of all 8 tiger subspecies. Conservation Status: Extinct since the late 1930's or early 1940's [The last Bali tiger to be shot was believed to be a female in 1925. The Bali tiger were extinct around the end of 1937]

  9. Ground source heating & heatpumps

  10. Heat pump ground to water Horizontal sensor Vertical sensor

  11. Vertical sensor • Losse : 45 kW • Power of heat pump : 32 kW Choice of heat pump ground to water : - Vitocal 300-G, type BW/BWS : 6,2 à 35,2 kW • Coefficient of performance COP : 4,7 • Maximal temperature of departure : 65°C • Dimensions (Height x Width x Depth) : 970 x 600 x 1065 mm • Weight : 2 x 168 kg ( 35,2 kW)

  12. Installation externally • Number of geothermal probe : 10 • Depth drilling on geothermal probe : 50 m • Spacing between geothermal probes : 10 m

  13. Installation internally • Low temperature radiators FARAL of cast aluminium : • warm fast • cool slowly • are rather little expensive • Number of radiators : 88 • Connecting between heat pump and radiators : pipes PER (Polyethylene) • Number heat pump : 2

  14. Building services • Passive Ventilation System • Air-Tightness • Ventilation system • Water storage tank from rain water

  15. Passive Ventilation System • Heat Exchanger(TitonHRV1Q) • Comfort ventilation up to 300m3/h • Minimum energy consumption • Reducing carbon footprint • Moist and hard air extracted Directly • Less Noise (21dB) • Higher efficient heat exchanger up to 95% • Easy to maintain • Property running cost is low • Increasing property value

  16. Internal air-tightness • Air-tight buildings waste less energy and cause co2 • Vital to achieving passive build • Air- Tightness is 0.5 air changes per hour @ 50pa • Reduce maintains cost • 20% saving of electricity bill • VARIO Membrane(INTERAZUB) • Stronger than polythene • UV protected • Reducing moisture

  17. Natural Ventilation • Single Sided Ventilation • Required Air flow-67cbm/h • Helpful to improve indoor Air quality • Zero energy consumption • Low maintains • Lower initial cost • No noise like mechanical ventilation • Less hygienic problem with duct

  18. Rain Water Storage Tank • Avg. precipitation-25.74inch • Collection of water 781614 gallon water/year • Saving up to 50 % of water consumption • Use for Toilets, washing, and land scalping • NO Lime scale(less detergent required),kinder to plants • Help to increase property value (eco-friendly) • Storage capacity of tank 10,000 gallon • Save water save life

  27. DECISION

  28. Calculation of investment and returns in passive house and retrofitprojects Time: 20 yearsPresentvalueis € 99.032,26 Analysis of investmentrequired: “We have hypothesized that: - the Government founds covers 15% of the total costs; - at travel’s start the client’s capital must covers 10% of residual investment; - JESSICA covers 15% of the loan investment.”

  29. PossibleSCEnaries

  30. Value of the project “For actualization of saving energy we have assumed that this doesn’t finish at the end of the tenth year, therefore, for the last money return, we have utilized temporary costantreturn”

  32. Positive externalities of retrofit and passive house • benefits of sustainability; • quality of life of the inhabitants; • lesspoverty; • lower costs for the government; • increasedtourism.
