Assessing your knowledge Topic 1 About CBD Tenancy Lighting Assessment’s What is the CBD program The CBD program is the initiative of the Council of Australian Governments (COAG). The program was established under the Building Energy Efficiency Disclosure Act 2010 and is managed by the Australian Government Department of Industry Designed to promote the disclosure of energy efficiency information of large Australian office buildings with an outcome of improving the energy efficiency of these buildings. Objective of the CBD program To disclose consistent and meaningful energy efficiency information about large office buildings that are for sale or lease to everyone (buyers, sellers and tenants). This information empowers the market with information that encourages energy efficiency improvements. Twin impacts – better price for efficient buildings, and lower greenhouse gas impacts. 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/ whole building NABERS rating ─ Part 2 - A Tenancy Lighting Assessment ─ Part 3 - Energy efficiency guidance for building owners and tenants What is a CBD Tenancy Lighting Assessment? An assessment of the energy efficiency of office lighting systems ─ Lighting power density “General lighting system” - primarily open plan 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 Why have the assessments? Provide information to prospective tenants or owners about the efficiency of the system ─ Effects cost to run of different spaces ─ Effects NABERS Tenancy Energy ratings. Provides guidance to owners / tenants to upgrade inefficient lighting systems Leasa App – assisting tenants to choose energy efficient office space Guiding principles Fair comparison between tenancies Robust and repeatable Cost effective and timely Extract from sample BEEC BEEC – Cover page Building details Assessor details NABERS Rating Lighting Assessment coverage Energy efficiency guidance Extract from sample BEEC BEEC – Part 1 NABERS Energy Star Rating NABERS Rating scope, area and hours Assessment of building energy performance NABERS Assessor who conducted the rating Extract from sample BEEC BEEC – Part 2 Assessment of General Lighting System efficiency ─ Power density ─ Control capacity Note: Base building lighting efficiency covered by NABERS rating Extract from sample BEEC BEEC – Part 3 General energy efficiency guidance This information comes with all BEECs Who can do a Tenancy Lighting Assessment Accredited CBD assessor ─ Check the CBD website www.cbd.gov.au Training requirements ─ Must be a fully accredited NABERS assessor ─ Attend this session and pass the accreditation exam ─ Pass the CBD program module (online via CBD website) ─ Register for the CBD assessor portal (instructions provided by CBD team) Processes and procedures Customer ─ Agree fee for services including possible initial site investigation ─ Obtain required information Tenants ─ Negotiate access, ensure all parties are aware that someone will be entering their offices to assess lighting, sometimes you may need to do it after hours Security and OH&S ─ Follow all site and tenant induction and OH&S requirements ─ Have general and site specific safe work methods statements Lighting Assessment process Site inspection Complete the Tenancy Lighting Assessment (TLA) form Submit TLA form to CBD team CBD team auditing the TLA application CBD team issue a TLA assessment number Assessment timing Lodge assessment within 4 months of assessment date (1st day of site inspection) Up to 15 days to process TLA application Up to 28 days to process a BEEC application Inform clients of processing timeframes No prioritisation 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 Record keeping processes Logical filing of evidence is essential Poor documentation is the primary cause for failing audits Rating form provides guidance on documentation requirements Lighting assessments can be audited up to seven years after the BEEC has been issued 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 Topic 2 Understanding the rules Functional spaces Break areas to assess into separate functional spaces Separate assessment per functional space Acceptable names for a functional space when part floor is selected: ─ Level 1, West Tenancy ─ Level 10, East Not acceptable part floor functional space name: ─ 10 or 12.03 ─ Open office ─ Suite 103 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 Naming functional spaces - example This is on level 2 of the building Acceptable use names of: ─ Level 2 Suite 1 ─ Level 2 Suite 2 Unacceptable use names of: ─ 12.03 ─ Open Office ─ Suite 103 General lighting system Lighting to illuminate the workstation areas of the tenancy May include “base building” and “fit-out” fittings Not desk-top task lighting Feature lighting is captured under some assessment methodologies Both are part of the general lighting system 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 General lighting system - example Included Both are part of the general lighting system ─ Troffers ─ Up lights Excluded ─ Exit lights ─ Emergency lights Exit lights are excluded General lighting system identification Yes No Yes Group exercise – identify the general lighting system Work in a group, identify the general lighting system from the photos and plans downloaded You have 15 minutes General lighting system exercise 1 General lighting system exercise 2 General lighting system exercise 3 General lighting system exercise 3a General lighting system exercise 4 1200x600 grid General lighting exercise 5 1200x600 grid Nominal Lighting Power Density NLPD ─ Applies to general lighting system only ─ Dependent on luminaire power, number of luminaires and area ─ The possible assessment methods are Grid based Aggregate method (contains 3 options ) Typical range 6 – 20 W/m2 ─ Most buildings in 8 – 15 W/m2 range Nominal Lighting Power Density Five categories: ─ ─ ─ ─ ─ “Very poor” >18.1W/m² “Poor” 15.1-18W/m² “Median” 10.1-15W/m² “Good” 7.1-10.0W/m² “Excellent” <7W/m² Identifying luminaires Definition of terms Luminaire naming conventions Counting lamps Determining nominal lamp power 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 Counting lamps Must physically sight the lamps Diffusers and reflectors can give misleading lamp images Luminaire on the right has a single T8 lamp 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 Luminaire control gear fundamentals Identifying ballast types Identifying transformer types Determining luminaire power Identifying Ballast Types Using the ballast discriminator T5 – electronic only Looking up lamp model Inspecting lamp connection Identifying Transformer Types Visual inspection ─ Magnetic – larger, heavier ─ Smaller – details written on transformer ─ Use of ballast discriminator is not permitted, too unreliable Total luminaire power Standardised figures only – NLP may differ from actual power NLP = nominal lamp power Total luminaire power Standardised figures only – NLP may differ from actual power Other luminaire cases Voltage reduction devices, dimmers: ─ Assess as if no voltage reduction device or dimmer present T5 adapters ─ Assess as per T5 lamp of same type If still not covered: ─ Directly measure luminaire power or take from nameplate ─ Ensure safe work methods are followed ─ Engage specialist trades person if required Luminaire defaults Where inspection not possible, defaults may be used: ─ ─ ─ ─ ─ ─ Fluorescent: Highest T8 of same length GU10 Halogen downlight: 50W+mag transformer Other halogen/mercury vapour: 250W LED downlight: default figure based on aperture diameter LED retrofit linear: default based on length LED strip: 21W/m These are conservative figures T5 adapters LED fittings Luminaires – Documentation Requirements Photos of each luminaire depicting lamp type, lamp power, number of lamps and control gear AND/OR As installed equipment lists AND/OR Results of individual luminaire power tests OK for # lamps X Not OK for lamp W OK for # lamps X Not OK for lamp W OK for lamp W X OK for grid X Group activity– identifying and naming luminaires Identify and name the luminaires shown in each of the photographs provided Try to identify ─ Luminaire type ─ Lamp power ─ Control gear type ─ Any additional information needed to work out total luminaire power Luminaire identification 1 Dimensions 1.2m x 0.3m T5 lamp ANSWER • Recessed T5 troffer, • Can’t tell the power without checking the lamp label • Could be 28W (T5 HE) or 54W (T5 HO) Luminaire identification 2 ANSWER • Recessed T8 troffer, • Can’t tell the power without checking the lamp label • Must use ballast discriminator to check control gear type Luminaire identification 3 ANSWER • CFL Downlight • 2 lamps • Lamp power is 13W • Control gear – need to check with ballast discriminator (or look up lamp model – this one is magnetic) Luminaire identification 4 ANSWER • Halogen downlight • Can’t tell lamp power from photo, could be 20W, 35W or 50W • Visual inspection to find control gear type • If unsafe to inspect – assume 50W lamp with magnetic transformer Luminaire type evidence Visual inspection of the luminaires Photographs of the system components ─ Lamps ─ Evidence of ballast/transformer type ─ Overall luminaire Luminaires Any questions on luminaire identification? Assessing NLPD Four methods Grid method – works for open plan with regular grid 3 aggregate methods – increasingly flexible methods for sites that are more complex Assessing NLPD When is a Functional Space assessable? A functional space is assessable if: ─ It contains >50m² of qualifying office space AND ─ Qualifying office space is >15% of area AND ─ There is an existing or proposed lighting system for these areas Qualifying office space = space for workstations or desks ─ Excludes meeting rooms, reception areas, function rooms, toilets, kitchens, storage and utility, 2-walled corridors Cell office - OK Aggregate Method 2 - suitable space Cell office - OK Open plan OK Server room – NO Building Core – NO Cell office - OK Resource room – NO Corridors – not OK Cell office - OK Tea room – NO Meeting rooms, etc NO Non-assessable functional space documentation requirements Floor plan or dimensioned mock-up showing qualifying office space <50m² or <15% of functional space area AND/OR Photos showing lack of lighting system AND Site notes identifying lack of proposed system Grid method of assessment Permitted when ─ Simple repeating block consisting of up to two luminaires covering open plan area of at least 50% of the space area or 250m², whichever is smaller; AND ─ Less than 5% (by wattage) deviation from the repeated block; AND ─ Documentation requirements for grid method can be met Grid method of assessment Use for regular arrays 0.6m Identifying the array Measure the grid spacing ─ Need actual measurement of tile size – don’t assume 1.2m 2 tiles 4 tiles Grid spacing 400 1200 1350 450 Grid spacing Look for repeating patterns In this example, assume a 1200x600 grid tile Alternate spacing 2400 and 1800 Average 2400x2100 spacing Grid spacing Staggered array Area per luminaire Grid spacing Another staggered array Do not be confused ─ Look for the symmetry Grid Method Documentation Requirements Reflected ceiling plan (Plan/mock up/photo) demonstrating grid; AND Plan/mock up showing that the minimum coverage requirement is met; AND Photos/site notes/drawings showing that nonstandard fittings < 5% watts across open plan; AND Photos/site notes identifying qualifying luminaire types in grid Grid Method - suitable space Repeating block: ─ >50% functional space area ─ >250m² <5% of luminaires in open plan not same as main luminaire Grid Method - unsuitable space Perimeter luminaire>5% by wattage Aggregate Method 1 – Open Space Permitted when ─ There is open plan area of at least 50% of the space area or 250m², whichever is smaller; AND ─ Documentation requirements for Aggregate Method 1 can be met Use for most irregular or multi luminaire configurations where there is enough open plan Aggregate Method 1 Identify an open plan space that: ─ Is either>50% of space area or>250m², whichever is smaller ─ Contains all the luminaire types used in the open plan area in a similar proportion to the open plan area as a whole OR, if no such space available ─ Use the whole open plan qualifying office space Aggregate Method 1 Prepare drawing of sample space Calculate sample space area better than 5% accuracy Count all luminaires in sample space Enter data into spreadsheet Aggregate Method 1 Documentation Requirements Reflected ceiling plan (Plan/mock up/photo) demonstrating irregularity of layout;

AND ─ Documentation requirements for Aggregate Method 2 can be met Use where there is inadequate open plan for the grid method or aggregate method 1 Aggregate Method 2 Identify a qualifying office space made up of open plan and cell offices that: ─ Is either>50% of space area or>250m², whichever is smaller ─ Contains all the luminaire types used in the open plan area in a similar proportion to the open plan area as a whole OR, if no such space available ─ Use the whole qualifying office space Aggregate Method 2 Prepare drawing of sample space Calculate sample space area better than 5% accuracy Count all luminaires in sample space Enter data into spreadsheet Aggregate Method 2 Documentation Requirements Reflected ceiling plan (Plan/mock up/photo) demonstrating irregularity of layout; AND Plan/mock up showing aggregate method sample space; AND Photos/site notes identifying qualifying luminaire types in aggregate method sample space; AND Site notes count of all luminaires within aggregate method sample space Aggregate Method 2 - suitable space 115m² Open plan space <250m² and <50% - too small for Aggregate Methodaggregate method 1 2 – sample spaces 286m² - OK Aggregate Method 2 - suitable space Aggregate Method 2 – sample spaces 386m² - OK Aggregate Method 2 - suitable space Aggregate Method 2 – sample spaces Aggregate Method 2 - suitable space 179m² - too small Aggregate Method 2 – sample spaces Aggregate Method 2 - suitable space 294m² OK Aggregate Method 2 – sample spaces Aggregate Method 3 – Entire Functional Space Permitted when ─ Space cannot be assessed under Grid Method, Aggregate Method 1 or Aggregate Method 2; OR ─ Space is under 250m² Use for small functional spaces or where the documentation is too poor to meet requirements for the other methods. Aggregate Method 3 Identify area of Functional Space to 5% accuracy Count all luminaires in sample space Enter data into spreadsheet Aggregate Method 3 Documentation Requirements Area of functional space to 5% accuracy Photos/site notes identifying qualifying luminaire types in space; AND Site notes count of all luminaires within functional space Grid and Aggregate Methods exercise 1 How would you assess this space? Tenancy is a single open office area of 240m² Grid and Aggregate Methods exercise 2 How would you assess this space? Grid and aggregate method assessment Any questions on grid or aggregate method assessment? Lighting control assessment Assessed as “control capacity” Assess only the control system’s capacity to deliver outcomes No assumptions on how well it is actually working Lighting controls Control capacity assessed as Good, Moderate or Poor Look at the main control system for the space Two factors to consider ─ Switching zone size ─ Control strategy Control strategy Three basic control strategies to assess ─ Manual ─ Time based ─ Occupancy based Occupancy sensors Occupancy control ─ Luminaires on supervisory control with occupancy sensors available ─ Luminaires hardwired to occupancy sensors ─ Luminaires with occupancy sensor and timer control Timer Control Timer control ─ Luminaire connected to a supervisory control system ─ Luminaire controlled by time switch ─ Luminaire interlinked to turn off when security alarm set Manual Control Manual control ─ Anything which doesn’t meet the requirements of timer or occupancy sensor control Bell press switch is not sufficient evidence of a timer control system Daylight sensors Not included in control grading May be integrated into occupancy sensors Control Type Flow Chart Control Technology Documentation Presence of occupancy control ─ Photos/docos for sensors AND ─ Drawing/mock up of sensor locations OR count of sensors Presence of supervisory control ─ Manuals, photo of interface, controllers, switch type Presence of time switch ─ Manuals, photos, drawings Manual Control – no documentation Control Technology Documentation Sketch or commentary reasonably demonstrating coverage of the occupancy/timer system is greater than 50% Can’t document it? ─ Then you can’t claim that level of control ─ Try the level below Switching zone size Three switching zone sizes to assess ─ Up to 100m² ─ From 100 to 250m² ─ Over 250m² Assessment is based on the largest switching zone in the functional space Control Capacity Control Zone Documentation Lighting control zone area documentation ─ Only required for spaces claiming occupancy control ─ Marked up scale drawing showing fittings, control zones and area of each control zone Functional space area documentation ─ Only required for manual space control spaces under 250m² Switching size example Sensors marked in red All areas are controlled by the occupancy sensors Ceiling tile is 1.2m x 0.4m Switching size example Case 1 – motion on any sensor turns all the lights on Switching zone size is >250m2 Control capacity is “moderate” Switching size example Case 2 – motion sensors control local area only Largest switching zone size is <100m2 Control capacity = “good” Effect of switching zone size Small switching zone (50m²) Large switching zone (2,000m²) Control Capacity Any questions on control capacity identification? Proposed systems Lighting system is to be upgraded within 3 months of the assessment date Assessments cover both NLPD and control capacity Must assess the existing system too ─ Proposed systems are not a substitute for an existing system assessment Proposed system assessments are optional Assessment of proposed system May arise from contractual commitment to upgrade lighting system ─ Owner proposed lighting upgrade ─ Make good provision Must be contracted with an agreed completion date within 3 months of assessment date Contract must be sighted by assessor ─ Retain copy of contract or relevant pages as evidence Assessment of proposed system Must be fully documented ─ Luminaire selections complete ─ Control strategy clearly set out ─ Control equipment selected Assess existing and proposed Difficult Buildings Exemptions for Buildings Denial of access or information to complete ratings Non-assessable spaces for the TLA component Exemptions from Disclosure Obligations A building may apply for an exemption if: ─ It is used for police or security operations; or ─ It can’t be assessed due to the characteristics of the building or area of the building. Submission of exemption application does not allow marketing or negotiation of the property until the exemption is granted. Exemption - Process Police or security operations ─ Gather details on the nature of operations within the building ─ Seek exemption from the Department of Industry under BEED Act Clause 17 (3) (a) ─ Note: Security is generally interpreted as being national as opposed to corporate or commercial security • Provide detailed reasons in the application form why exemption is required. • Exemptions are provided at the discretion of the Department. Exemption - Process Non assessable Building ─ Gather detailed evidence demonstrating why building is not assessable, e.g. Detailed reasons why rating can’t be completed Any statement from NABERS indicating a rating can’t be provided ─ Seek exemption from Department of Industry under clause 17(3)(b) ─ Record details on application form specifically identifying reasons why building is not assessable Access Denial - Process If a tenant/owner refuses access or information ─ Assessors can require information or access be provided by owners or tenants (lessees) if it is necessary for an assessment. The Department provides templates for requests ─ If an owner or lessee still refuses access or information after a request, they must apply for an exemption under clause 18(7). If access or information is refused without an exemption, this is a breach of a civil penalty provision. Penalties apply. Exemptions granted under 18(7) may support claims of inability to conduct an assessment under clause 17(3)(b); Where a functional space does not allow a TLA Assessment An assessment may not be possible because space is: ─ Under refurbishment No lighting system in place; or Lighting system is incomplete (luminaires missing) ─ Non office fit-out Extensively fitted out with small cellular offices, meeting rooms or conference rooms Where a space does not qualify for an exemption Assessor needs to include the space in the assessment form Mark the space as not assessable on the FS tab Provide a reason why the space was not assessable ─ Include a reference to the clause in the rules used to determine the space as not assessable Difficult Buildings Any questions on exemptions, non-assessable spaces or denial of access?
