  2. LIGHTING FOR LIVINGTODAY TODAY What are the new requirements and why ? What do they really mean for the home owner? Optimal versus minimal outcomes? Is the day of the Down Light gone?

  3. LIGHTING FOR LIVINGWHY ARE WE DOING THIS? The Building Code of Australia. Now the National Construction Code or NCC Introduced Regulations detailing energy efficiency requirements Commercial Buildings 2006 Residential was introduced in Victoria from 1 May 2011 Comprehensive Strategy aimed at All Buildings throughout Australia To address factors affecting global warming

  4. LIGHTING FOR LIVINGWHY REGULATE? Why Regulate? Growing Building Energy Sector New residential market $2.4 Billion P.A Renovation market $2.5 Billion P.A Adding houses with poor energy efficiency means GHGE continue to increase & impact is extended to the next generation.

  5. LIGHTING FOR LIVINGENERGY EFFICIENCY The BCA (NCC) is designed to promote the prudent use of energy by Regulatory measures Voluntary choices It uses building design to achieve this Incorporates a lot more than electrical

  6. LIGHTING FOR LIVINGADMINISTRATION of the BCA Federally Enacted but administered through the individual State and Territory Building Acts Building Regulations For example in Victoria it is the Building Commission BCA also calls up relevant Australian Standards

  7. LIGHTING FOR LIVINGWhat is covered under the new requirements Building Classification, Classed from 1 to 10. Class is determined by purpose for which it is designed Classifications 3-9 (commercial) have had energy requirements since 2006 Class 1a A single dwelling Either detached house; or One of a group of two or more separated by a fire-wall Class 1b A boarding house, guest house, hostel or the like Total floor area not exceeding 300m2 Not more than 12 persons ordinarily resident Class 2 Multi Residential Class 10 Non-inhabitable building or structure Being a garage, carport, or shed

  8. LIGHTING FOR LIVINGADMINISTRATIVE ARRANGEMENTS currently BCA technical requirements have to be satisfied in order to gain approval of a building proposal Plan submission and approval procedures. Issue of building permits. Inspections during and after construction. Provision of evidentiary certificates. Issue of certificates of occupancy or compliance. Accreditation or approval of materials or components. Review and enforcement of standards. Fees and charges. How do we handle this for residential lighting?

  9. LIGHTING FOR LIVINGCOMPLIANCE VARIFICATION - HOW & WHEN? This is possibly the most unclear area as to what is needed to be provided. Lighting design? What does that entail? When should this be considered? Before plans submitted The customer will need input.

  10. LIGHTING FOR LIVINGDESIGN INPUT / TECHNICAL KNOWLEDGE

  11. LIGHTING FOR LIVING • What are the requirements of the NCC? • Only affects NEW home construction……..at this stage

  12. LIGHTING FOR LIVINGPART J6 – ARTIFICIAL LIGHT & POWER Lamp Power Density or Illumination Power Density Excluding heaters that emit light Must NOT Exceed In a Class 1 & Class 2 residential building, 5 W/m2 On a verandah or balcony, 4 W/m2 In a class 10 (garage) , 3 W/m2 NOTE: where Illumination Power Density is used it may be increased by dividing it by the adjustment factor (refer Table 3.12.5.3)

  13. LIGHTING FOR LIVINGCALCULATION METHODS Two methods Illumination Power Density, or Lamp Power Density Why? It accounts for control systems

  14. LIGHTING FOR LIVINGPART J6 – ARTIFICIAL LIGHT & POWER Lamp Power Density - The simplest method of calculation Total power consumed by lamps, excluding ballasts, etc Total = nominal wattage of all lamps in the space / floor area of space Lamps powered from GPO’s are not included GPO’s controlled by wall switches MUST COMPLY

  15. LIGHTING FOR LIVINGPART J6 – ARTIFICIAL LIGHT & POWER Lamp Power Density

  16. LIGHTING FOR LIVINGPART J6 – ARTIFICIAL LIGHT & POWER Lamp Power Density Ground Floor (5w/m2) 208.88 x 5 = 1044.4 watts Garage (3w/m2) 37.48 x 3 = 112.4 watts Porch / Alfresco (4w/m2) 4.11 + 10.32 x 4 = 57.7 watts Total allowance for house 1214.5 watts

  17. LIGHTING FOR LIVINGPART J6 – ARTIFICIAL LIGHT & POWER Illumination Power Density Calculates the Total power consumed by lamps, ballasts, current regulators & control devices Total = power used / floor area of space Lamps powered from GPO’s are not included GPO’s controlled by wall switches MUST COMPLY + +

  18. LIGHTING FOR LIVINGPART J6.2(a) – ADJUSTMENT FACTORS Illumination Power Density Adjustment Factors Subclause J6.2(a)(ii) provides an alternative approach for dwellings with sophisticated control systems These controls are likely to reduce energy used A concession is given on the lighting power limit Recognises situations where sensors, switching devices, control systems have an impact on performance of lighting Clause J6.2(a)(iii) requires Illumination Power Density to be used

  19. LIGHTING FOR LIVINGPART J6.2(a) – ADJUSTMENT FACTORS Illumination Power Density Adjustment Factor Notes Manual Dimming Programmed dimming Dynamic Dimming Fixed Dimming Adjustment factors do not apply to incandescent or halogen lamps Either LPD or IPD must be used not nominal allowance for batten holder Where transformers are used - must be electronic type Halogen lamps must be separately switched from fluorescent Exterior lighting must be controlled by daylight sensor, or Lamp efficacy of not less than 40 lumens / watt

  23. LIGHTING FOR LIVINGLighting Design considerations Outcome / Objective-what are you trying to achieve? Lifestyle and / or cost Technology. What options do we have? Cost. Installation and running How is the light to be used? Decorative /practical / mood

  24. LIGHTING FOR LIVINGTECHNICAL PROVISION OVERVIEW The BCA stipulates maximum power density specified as a maximum limitation of watts per square metre The BCA does NOT specify the type or configuration of lighting installed The BCA does NOT specify the required lighting levels in a dwelling These decisions are design driven applications The stipulation under BCA requirements is 5 W/m2 for interiors, 4W/m2 for verandahs and balcony & 3 W/m2 for garages, etc.
