Energy and Environment Expo Presentation - Indoor Air Quality for Buildings for Health , Personal Comfort and Working Efficiency

  1. 1. Paul Newton Ltd June 2014 Indoor Air Quality for Buildings For Health , Personal Comfort and Working Efficiency Optimising Building Air Systems Energy and Running cost reductions
  2. 2. Clean air solutionsClean air solutionsClean air solutions Camfil’s business concept – clean air Our business concept is to deliver value to customers all over the world while contributing to something essential to everyone – clean air Clean air solutionsClean air solutionsClean air solutions
  3. 3. Clean air solutionsClean air solutionsClean air solutions Outdoor Air Pollution Clean air solutionsClean air solutionsClean air solutions Particles: Traffic combustion particles, Power Stations, Pollen Definition of size: 0.01 – 100 µm • PM 2.5 • PM 10 Gases: Random movement, molecular size Gas molecule size < 0.001 µm • Nitrogen Dioxide • Ozone • Sulphur Dioxide • VOCs
  4. 4. Clean air solutionsClean air solutionsClean air solutions Indoor Air Pollution Clean air solutionsClean air solutionsClean air solutions • We spend 90% of our time inside • 50 % of all particles inside come from outdoor air – Heating and Traffic particles • 50 % are generated from indoor sources – Building materials, cleaning products, air fresheners • A big part of the population lives and works in areas where rates of particles exceed WHO guidelines regarding PM2.5 (10ug/m3/year)
  5. 5. How small are these particles? Clean air solutionsClean air solutionsClean air solutions
  6. 6. Presentation Title 6
  7. 7. Comfort Air Filters A healthy and beneficial climate • Offices • Hotels • Schools • Shopping centres • Conference centres • Airports Clean air solutionsClean air solutionsClean air solutions
  8. 8. Results of poor Air Filtration in Ventilation Systems Clean air solutionsClean air solutionsClean air solutions • Air flows reduced • Ducts filled with fine dust resulting in micro organism growth • Heating and cooling coils blocked • High cleaning and Energy costs • Indoor Air Quality issues for Health
  9. 9. Air Handling Unit energy flow Pre-filter Secondary-filter Intake Air Frost coil Supply Air Damper Heating coil Cooling coil FAN MOTOR Gas-filter (Carbon) Attenuator OUTSIDE INSIDE Electrical Energy input via motor
  10. 10. Clean air solutionsClean air solutionsClean air solutions Air Filter - Energy Equation Clean air solutionsClean air solutionsClean air solutions Calculations reveal that energy normally accounts for 70% of the total life cycle cost of the system. The energy consumption is directly proportional to the average pressure drop over the filter. Energy (E) = [(Q x ∆P x T)/(ŋ x Co)] . Pc • Q: Air flow, m3/s • ∆P: Average filter pressure loss, Pa • T: Operation time, hr • ŋ: Fan efficiency, % • Pc: Cost of Power, p/kWh • Co: Constant, 1000 in SI units

Clean air solutionsClean air solutionsClean air solutions IndoorAirQualityforBuildings11 Low Energy Air Filter Solutions Carbon Filters: ’Citysorb’ (Gas) ’Citycarb’ (Gas+Particle) Single Stage Bag Solution ’Hi-Flo’ Primary Filter ’30/30’ Secondary Rigid Compact Filter ’Opakfil Energy’ Eurovent Energy Rated Products
  12. 12. Clean air solutionsClean air solutionsClean air solutions Air Filter - Life Cycle Costing model Clean air solutionsClean air solutionsClean air solutions The life cycle cost for the filter is the cost of: Low Cost Filter Low Energy filter 1. Filter purchase 12% 35% 2. Labour 12% 11% 3. Energy used 70% 50% 4. Waste Disposal 6% 4% = Total Cost of Ownership
  13. 13. Clean air solutionsClean air solutionsClean air solutions Camfil Software - Life Cycle Costing Calculation for Air Filters Clean air solutionsClean air solutionsClean air solutions Parameters the software includes: • Type of filters in use: Outside air condition • Airflow rates • Number of filters in the air-handling units • Current change out conditions • Current energy cost • Installation cost • Disposal and cleaning cost
  14. 14. Clean air solutionsClean air solutionsClean air solutions Air Filter Standards and Guidelines IndoorAirQualityforBuildings14 Current Test Standard BS EN779 : 2012 Air Filter particle efficiency Indoor Air Quality Standard: BS EN13779 : 2007 Particle and Gas Phase Filtration guidelines Ventilation for buildings BS EN15780 : 2011 Inspection regimes - Internal Cleanliness of Ventilation Systems Eurovent Certified Air Filters New Energy grading for filters ratings from A to G
  15. 15. Air Handling Unit demonstrator shows live data energy savings with Low Energy Air Filter optimisation Air Filter Energy Savings - Demonstration
  16. 16. Clean air solutionsClean air solutionsClean air solutions Fan Motor Energy Reduction Clean air solutionsClean air solutionsClean air solutions Maximum AHU system energy conservation comes from a dual strategy of optimising static components, and use of a Variable Speed Drive (VSD) or Inverter to the fan motor:
  17. 17. Indoor Air Quality for Buildings 17 Stand alone portable air cleaners provide a practical health and economic solution Fast response and portable to give Clean Indoor Air Quality CamCleaner – Air Purifier
  18. 18. Clean air solutionsClean air solutionsClean air solutions Results of Good Indoor Air quality Clean air solutionsClean air solutionsClean air solutions Consequences on productivity and absenteeism • Productivity can be improved by 10% in the workplace from better indoor air quality • Improved ventilation systems can save 400 Euros per year per employee • Reduce sick leave rate by 30% * INIVE - International Network for Information on Ventilation and Energy Performance
