  2. About Hector's dolphin • Physical Characteristics • Diet • Social Structure • Breeding • Facts : • Hector’s dolphin was named after James Hector who is believed to be the first person to have examined this species. • These dolphins are only found living in the waters of New Zealand throughout the year. • Due to pollution, boating and other activities over the past 30 – 40 years number of these dolphins have reduced from around 26,000 to less than 7,500

  3. The main tasks of the project • Energy efficiency; • Building services; • Green roofs and facades; • Calculation of investment and returns in passive house and retrofit projects.

  4. Energy efficiency • Analysing current situation • Thermal bridges • Choosing materials and windows • Energy demand on heating • Costs

  5. Energy efficiency.Current situation • U-values (old construction):

  6. Energy efficiency. Thermal bridges • Energy demand on heating: 160 kWh/m²y

  7. Energy efficiency. Thermal bridges solutions • Bring windows out into the insulation layer • Insulate balcony slab • Quality of construction works

  8. Energy efficiency. Insulation • Foamglas® insulation • Low environmental pollution • 66% recycled glass • Only renewable energy is used

  9. Energy efficiency. Windows and doors • Triple glazed windows U=0,78 • Double glazed in basement and stairwell U= 1,0 • Stairwell facade • New entrance doors • Balconies are glazed with tempered glass

  10. Energy efficiency. Energy Management effect • Energy demand on heating: 26 kWh/m²y

  11. Energy efficiency. Costs • First option 477 000 € • Foamglas® insulation • Alternative option 246 000 € • Rockwool insulation

  12. Building services • Heating system; • Water recycling system; • Ventilation system.

  13. Building services. Heating system What is district heating? District heating is friendly for environment ? How does district Heating work? How do we improve the temperature control in our project? 2. Valve 1. Radiator

  14. Building services. Water recycling system Advantages and disadvantages How to utilize the rain water?

  15. Building services. Ventilation system Mechanical exhaust ventilation How it works? Some examples of design:

  16. Green roofs and facades • Green roof Benefits:

  17. Green roofs and facades • Green roof Technology VEDAFLOR ® green roof Plus

  18. Green roofs and facades • Living wall Function

  19. Green roofs and facades Technology • Living wall 16mm diam. pipework ANS living wall module Drainage channel Waterproof membrane FSC pressure treated softwood battens ANS fixing rails Indicative existing structure Pre-planted before installation Fitted to fixing rails

  20. Green roofs and facades First option Second option

  21. Calculation of investment and returns in passive house and retrofit projects • Financial program • Renovation costs calculation • Cost of energy before and after renovation • Loan and savings calculation • Financial characteristics

  22. Calculation of investment and returns in passive house and retrofit projects

  23. Calculation of investment and returns in passive house and retrofit projects

  24. Calculation of investment and returns in passive house and retrofit projects

  25. Calculation of investment and returns in passive house and retrofit projects Financial characteristics • Payback period 22 years • NPV 21, 042 € • ROI3,76 %

  26. Conclusion Outcomes • Changes in tenant energy expenditure • Changes in carbon emissions for the environment • Health impacts on tenants and associated costs saved to society • Tenant comfort levels • Community effects

  27. Thank you for your attention
