  1. Profitingfrom the Green Evolution ing. André R.P. Schoonenwolf (RI/ONRI) Senior M&E Consultant Hospitality Industry SINE Engineering BV - Amsterdam

  2. Our energy can be Green • Mr Gore has done a great job: • His message is clear and very convincing • His environmental PR work is great • He really opened the eyes of the world • But …… experts do have comments

  3. Green is red hot! Mr. Al Gore recently in Holland: “You Dutchmen should use Wind Energy”

  4. Map of Holland

  5. Our energy sources • Just think about it for a moment: • Winds are generated by the sun heating the earth, • Waves are caused by wind blowing over water • Water covers around three-quarters of the earth • We still use so little of the natural sources!

  6. Are you really Green? Is your project environmentally driven? Do you go for sustainability? Is it your Green Image(Green Key)? or is it just: Reduction of exploitation costs?

  7. How sustainable can we go? It must be a special approach Team up experienced specialists Integration of the various designs Architect Statics M&E User Just target all possible details Go straight for your goal

  8. Integrated design is precision

  9. Services = Exploitation Plan Costs more Carefully Demand Investment Guarantees Avoid Extra Costs Services in €uro’s: >30 % of building costs Reduce Exploitation costs

  10. Alternative energy sources • Energy from the earth by Aquifiers(closed wells) • Low temperature heating • High temperature cooling • Wind energy (electric power) • Solar energy (hot water & electricity) • Sea, river & lake water (cooling) or wave-tech? • Sewarage water recycling for garden irrigation

  11. Upgrade Now! • Focus on the new low cost hotel formulas • They use the smart and green technologies • Smart technology raises efficiency • Digital systems prove to save money • But: dare to KISS!

  12. Sustainability • How sustainable are our thoughts • Don’t talk but just act • Examples and experiences enough • Use effects with proven results

  13. USP for Your hotel Green concept & your Guest=USP • Energy & Environment: World Standard NOW! • The guest is E&E-sensitive (marketing reviews) • Ideal combination: Comfort & Low Energy use

  14. You will be forced to followJust an example

  15. Brushless Fan coil Motor NEW DEVELOPMENTS

  16. The Brushless motor • Life time increase with less maintenance. • Less noise (no vibrations at high speeds). • More reliable • Better cooling (3 times less capacity to dispatch ) • More flexibility in speed choice and higher torque • Working point closer to the need • Energy saving (lower absorbed power, optimal efficiency) • Lower subscribed electrical power for the building

  17. Energy saving with Hee fan impeller + Brushless Energy saving with Hee fan + standard motor Brushless Fan coil Motor

  18. Induction units No Noise & No Energy consumption!

  19. Effect of Induction Units • Lack of moving parts • Pressure control is super effective • No guest around = 50 % air reduction • Interesting in investment (-18 %) • Interesting in exploitation (-26 %)

  20. Results of Modern Refrigeration • Electrical use 65 % to conventional • Heat recovery for preheating of domestic hot water and your swimming pool

  21. A sustainable hotel Dorint Hotel Schiphol Airport 443 rooms 15 kW instead of 1.1 MW power need Sorry,figures are confidential

  22. Cogeneration(CHP)

  23. Results Cogeneration • Combustion engine drives a generator • 30 % Electrical power generation • 60 % Heat generation( 80 grC ) • Ideal situation: Hotels! • Equal use of electricity and heat(hot water)

  24. Solar energy • Location is very important • Temperatures are crucial • High outside temperature means: • Hot water production • Photo voltaic process stops >35 grC  

  25. Example Solar Energy Example: 20 solar panels in Western Europe Yearly electricity production:2.280 kWh Investment:€ 20.200, maintenance: € 192  Yearly energy reduction :€ 502 (2008) Governmental energy bonus:€ 752.40(2008)  Yearly reduction in CO2: 1414 kg Return on investment: 16,1 year

  26. Example solar energy Same example: 20 panels in Southern Europe Yearly electricity production:4.490 kWh Investment:€ 20.200, maintenance: € 180  Yearly energy reduction :€ 1.302 (2008) Governmental energy bonus: non  Yearly reduction in CO2: 2738 kg Return on investment: 9,3 year

  27. Wind Energy

  28. Results Wind Energy • Depend on location(average wind force per country) • W.M. of 50 m high can deliver 750 kW(force 6 in NL) • West coast NL 800 -1200 kWh/year/m² • Mid country NL 500 - 800 kWh/year/m² • Comparison: Gambian Coast: 300-500 kWh/year/m2

  29. Results Wave technology • One must be near the sea • Regional energy aggregation only • Tides must help you (heights) Ideal locations Scotland(UK) & Bretagne(France)

  30. But what about Domestic Water • Raindance shower head(Hans Grohe) • Reduces water use with 43 % • Doubles guest comfort • Lowers maintenance • Lowers roomcost/night ( > € 0,45)

  31. LED lighting • Electrical use only 8 % of Tungsten lighting • Longer lifetime (30-50 times) • Precise selection of lamp type is needed

  32. LED = Cold atmosphere? • Soft    3000K/3500 K    • Warm 4000K/4500K •    Natural 5000K/5500K • Pure 6000K/6500K •    Cold 7000K/7500K

  33. LED high efficiency lighting • 6 times longer life( 35.000-45.000 hrs ) • 78 % reduction of power consumption

  34. Lower power needs? • Immediate power capacity reduction • Change or even take out Transformers ! Too much transformer capacity is reducing your financial results!

  35. Finally… • Upgrade your Technical Services Department • Screen their knowledge regularly • Promote new technology to them • Employ only quality. You need it now. • Raise your TSD efficiency and save money

  36. Profit from Technology

  37. Profit from New Technologies You will laugh €’s every day Thank you…
