  1. Greening The Living Rainforest Feije de Zwart Wageningen UR Greenhouse Horticulture

  2. Buildings of The Living Rainforest 760 m² 240 m² 50 m² Amazonica Lowlands propagation 1050 m² greenhouse 600 m² other buildings

  3. Simulated energy consumption of TLR 2006 Liter oil equivalent per day

  4. 250 ton/year 3500 liter/year Simulated energy consumption of TLR 2006 Liter oil kg woodchip (30% moisture) per day • 1400 • 1200 • 1000 • 800 • 600 • 400 • 200 • 0 0 woodchip oil

  5. 250 ton/year 3500 liter/year Simulated energy consumption of TLR 2006 Liter oil kg woodchip (30% moisture) per day • 1400 • 1200 • 1000 • 800 • 600 • 400 • 200 • 0 0 woodchip oil 40 times a year

  6. Proposed refurbisment TLR 800 m² 120 m² 400 m² Amazonica Lowland Offices 1200 m² new energy friendly greenhouse 650 m² other buildings

  7. 105 tonnes woodchip per year Energy consumption of complete refurbished TLR Oil equivalents [liter/day] 20% more greenhouse,10% more office surface 60% reduction of energy use

  8. Heat demand versus heat surplus winter summer

  9. Heat demand and heat surplus Oil equivalents [liter/day]

  10. Two problems: • How to extract the heat from the surplus • How to apply the extracted heat (seasonal asynchrony and low temperature)

  11. 24 °C 22 °C 10 12 16 20 24 20 16 12 10 Loading the VSHE 28 °C

  12. 11 6 2 6 11 16 18 16 12 10 Applying stored heat 30 °C 25 °C 2 °C 0 °C 22 °C

  13. Applying stored heat 1 unit electricity 4 units heat COP = 4 3 units from VSHE

  14. 44% from wood chips 56% from heat pump More than half of the heat comes from heat pump Oil equivalents [liter/day] 200 150 50 tonnes woodchip 60 MWh electricity 100 50 0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

  15. Heat pump, heat capture and VSHE Saving:55 tonnes woodchip per year

  16. First only a small renovation Amazonica Lowlands propagation

  17. First only a small renovation 760 m² 240 m² 200 m² 120 m² Amazonica Lowland new grnh Offices 1000 m² old, very energy inefficient greenhouses 200 m² new, energy friendly greenhouse 650 m² other buildings

  18. Thank you for your attention
