  1. Commercial Building Disclosure Accredited Assessor Training Course - Lighting May 2012

  2. Housekeeping • Duration • Breaks • OH&S • Evacuation • Turn off mobile phones

  3. Course coverage • About CBD Lighting Assessments • Understanding the rules • The assessment form • Example assessments • Assessing your knowledge

  4. Topic 1About CBD Lighting Assessments

  5. What is the CBD program • The CBD program is the initiative of the Australian and State/Territory Governments. • The program was established under the Building Energy Efficiency Disclosure Act 2010. • Designed to improve the energy efficiency of Australia’s larger office buildings.

  6. CBD Administration • National program • Managed by the Australian Government Department of Climate Change and Energy Efficiency

  7. Objective of the CBD program • The aim is to minimise asymmetric information between buyers and sellers about the relative energy efficiency of large office buildings that are for sale or lease. • This information empowers the market with information that will encourage energy efficiency improvements. • Twin impacts – better price for efficient buildings, and lower greenhouse gas impacts.

  8. What is Building Energy Efficiency Certificate • Under the Building Energy Efficiency Disclosure (BEED) Act 2010, • A Building Energy Efficiency Certificate (BEEC) is required for sale, lease or sub-lease office space of 2,000m² or more. • The BEEC is comprised of three parts • Part 1 - A base building NABERS rating • Part 2 - A Tenancy Lighting Energy Efficiency Assessment • Part 3 - Energy efficiency guidance for building owners and tenants

  9. What is a CBD Tenancy Lighting Assessment? • An assessment of the energy efficiency of office lighting systems • Lighting power density • General lighting only and not tenant feature lighting • Nominal – not the same as BCA Part J6 • Control capacity • No judgment on effectiveness • Doesn’t assess actual consumption • What it can do – not how it is currently used

  10. Why have the assessments? • Provide information to prospective tenants or owners about the efficiency of the system • Affects cost to run of different spaces • Affects NABERS Tenancy Energy ratings. • Incentivise owners / tenants to upgrade inefficient lighting systems

  11. Guiding principles • Fair comparison between tenancies • Robust and repeatable • Cost effective and timely

  12. Extract from sample BEECBEEC – Cover page • Building details • Assessor details • NABERS Rating • Lighting Assessment coverage

  13. Extract from sample BEECBEEC – Part 1 • NABERS Rating detail • Assessment of base building energy performance

  14. Extract from sample BEEC BEEC – Part 2 • Assessment of general Tenancy Lighting system efficiency • Power density • Control capacity • Note: Base building lighting efficiency covered by NABERS rating

  15. Extract from sample BEECBEEC – Part 3 • Generic energy efficiency guidance • Same information for all BEECs

  16. Who can do a Tenancy Lighting Assessment • Accredited CBD assessor • Check the CBD website www.cbd.gov.au • Training requirements • Must be a NABERS assessor • Must have completed a supervised NABERS energy for offices rating • Attend this session and pass the accreditation exam • Pass the Commercial Building Disclosure program module

  17. Processes and procedures • Customer • Agree fee • Obtain information • Tenants • Negotiate access • Security and OH&S • Follow all site and tenant induction and OH&S requirements • Have general and site specific safe work methods statements

  18. Lighting Assessment process • Site inspection • Fill out the Tenancy Lighting Assessment (TLA) form • Ensure all required information has been filled • Submit TLA form to CBD team • Auditing of application • Issue of TLA assessment number

  19. Assessment timing • Lodge assessment within 4 months of assessment date (1st day of site inspection) • Up to 28 days to process the Tenancy Lighting Assessment form • Up to 28 days to process the BEEC application • Inform clients of processing timeframes

  20. Record keeping processes • Retain records for seven years • Retain primary data from assessment • Site photos notes and marked up drawings • Leases or contractual agreements used in assessments • Summary data only is not acceptable • Must be sufficient for an assessor / auditor to repeat accurately the assessment from documentation only • All evidence needs to be provided to the CBD administrator upon request

  21. Record keeping processes • Logical filing of evidence is essential • Poor documentation is the primary cause for failing audits • Lighting assessments can be audited even seven years after the BEEC has been issued

  22. Administrative processes • Submission requirement • 4 months from date of first inspection to submission • Validity of assessment • Valid for 12 months from certification date • Interpretation of rules – CBD administrator • Dispute resolution • With client • With CBD administrator

  23. Topic 2Understanding the rules

  24. Functional spaces • Break areas to assess into separate functional spaces • Separate assessment per functional space • Acceptable names for a functional space:- Level 1, West Tenancy- Level 2, Whole Floor- Level 10, East • Not acceptable functional space names:- 10 or 12.03- Open office- Suite 103

  25. Functional space area • Maximum size is the smaller of: • Whole tenancy; or • Whole floor • Can define functional spaces to be the same as used for the NABERS rating • NLA required for the whole functional space • NLA to give perspective but not critical • Areas already required for NABERS rating so should be available

  26. Naming functional spaces - example • This is on level 2 of the building • Use names of: • Level 2 Suite 1 • Level 2 Suite 2

  27. General lighting system • In place when tenant moves in • Remains when tenant leaves and makes good • Not desk-top task lighting • Not feature lighting • Conference rooms • Reception

  28. General lighting system • Do not assess the quality of luminaires • Poor optics • Dirty / old • Failed lamps • Do not assess the quantity of light • Low lux levels • Dark areas

  29. General lighting system - example • Included • Troffers • Excluded • Exit lights • Up lights

  30. General lighting system identification

  31. Group exercise – identify the general lighting system • Work in a group, identify the general lighting system from the photos and plans provided • You have 15 minutes

  32. General lighting system exercise 1

  33. General lighting system exercise 2

  34. General lighting system exercise 3

  35. General lighting system exercise 3a

  36. General lighting system exercise 4 1200x600 grid

  37. General lighting exercise 5 1200x600 grid

  38. Nominal Lighting Power Density

  39. Nominal Lighting Power Density • Four categories: • “Poor” >15W/m² • “Median” 10.1-15W/m² • “Good” 7-10.0W/m² • “Excellent” <7W/m²

  40. Identifying luminaires • Definition of terms • Luminaire naming conventions • Counting lamps • Determining nominal lamp power

  41. Luminaire naming conventions • Suggested option • XXabb • XX is a luminaire body code (2 or more letters) • a is the number of lamps (single digit number) • bb is the nominal power of each lamp - typically 2 digits but may be 3 or more • If you need more information, precede with a plus sign • RT236 is a 2x36W recessed troffer • RT236 + LVR for louvred diffuser

  42. Luminaire naming conventions • Suggested option • XXabb • XX is a luminaire body code (2 or more letters) • a is the number of lamps (single digit number) • bb is the nominal power of each lamp - typically 2 digits but may be 3 or more • If you need more information, precede with a plus sign • RT236 is a 2x36W recessed troffer • RT236 + LVR for louvred diffuser

  43. Counting lamps • Must physically sight the lamps • Diffusers and reflectors can give misleading lamp images • Luminaire on the right has a single T8 lamp

  44. Determining lamp power • Use the nominal lamp power • Written on the lamp’s tube or base • Where unsafe to inspect use nominal 50W lamp power for halogen downlights

  45. Luminaire control gear fundamentals • Identifying ballast types • Identifying transformer types • Determining luminaire power

  46. Identifying Ballast Types • Using the ballast discriminator • T5 – electronic only • Looking up lamp model • Inspecting lamp connection

  47. Identifying Transformer Types • Visual inspection • Magnetic – larger, heavier • Smaller – details written on transformer • Ballast discriminator with care • If pointed at transformer (not lamp) • Provided ceiling/obstructions aren’t too strong

  48. Total luminaire power • Standardized figures only – NLP may differ from actual power NLP = nominal lamp power

  49. Other luminaires • For luminaire types not scheduled eg • LED • T5 adapters • Directly measure luminaire power or take from nameplate • Ensure safe work methods are followed • Engage specialist trades person if required

  50. T5 adapters
