2 About Hector's dolphin Physical Characteristics Diet Social Structure Breeding Facts : Hectors 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 2

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. 3

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

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

6 Energy efficiency. Thermal bridges Energy demand on heating: 160 kWh/m²y 6 Thermal bridges (current)Lenght (m) Value (W/mK) H (W/K) External wall - ext. wall, outside corner175,940,587,97 Ext. wall - ext. wall, inside corner121,4-0,2-24,29 Floor - ext. wall1020,440,68 Roof - ext. wall1020,440,68 Windows and doors perimeter8370,4334,80 Ext. wall - intermediate ceiling4070,3122,04 Balcony - ext. wall118,80,671,28 673,16

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

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

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 9

10 Energy efficiency. Energy Management effect Energy demand on heating: 26 kWh/m²y 10 Thermal bridges (after)Lenght (m)Value (W/mK) H (W/K) External wall - ext. wall, outside corner175,940,117,59 Ext. wall - ext. wall, inside corner121,4-0,1-12,14 Floor - ext. wall1020,022,03 Roof - ext. wall1020,110,17 Windows and doors perimeter8370,018,37 Ext. wall - intermediate ceiling4070,0520,34 Balcony - ext. wall118,80,111,88 Total 58,24

11 Energy efficiency. Costs First option – Foamglas® insulation Alternative option – Rockwool insulation 11

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

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

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

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

16 Green roofs and facades Green roof Benefits: Stemming the flow of water off a roof; Noise reductionBlocks out UV lightLessens heat gainAdditional layer of thermal insulation Green space in a city.Absorb the high levels of carbon dioxide 16

17 Green roofs and facades Green roof Technology VEDAFLOR ® green roof Plus 9. Sedum, small vegetation 8. Light mineral substrate E (thickness 8-10 cm) 7. Drainage mat / vegetative plate (thickness 20mm) 6. Distinctive layers of polyethylene film (thickness 0.2 mm) 5. Bituminous coating VEDAFLOR ® WS-I - Root penetration resistance second waterproof layer 4. Bituminous coating VEDAFLOR ® WS-U - root penetration resistance first waterproof layer 3. Foamglas T4+ Slab 2x150 mm Foamglas T4+ Slab 100 mm 2. Vapour barrier VEDAGARD ® SK-PLUS 1. Roof deck 17

18 Green roofs and facades Living wall Function Means for water reuse Plants reduce overall temperatures of the building Used for urban agriculture, urban gardening, or for its beauty as art Alleviate sick building syndrome 18

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

20 Green roofs and facades First option Second option 20

21 Calculation of investment and returns in passive house and retrofit projects 21 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 Type of worksConstruction costs, Ventilation5 158 Water recycling Heating system Green roof+ facade Walls, roof, basement wall and floor, windows TOTAL Support program 30% TOTAL

23 Calculation of investment and returns in passive house and retrofit projects 23 Costs, Heating needed (kWh/m²*y) 13,56159,63Before renovation 2,2226,18After renovation 11,34133,45Savings on heating

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

25 Calculation of investment and returns in passive house and retrofit projects 25 Financial characteristics Payback period 22 years NPV 21, 042 ROI 3,76 %

26 Conclusion 26 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
