LIGHTING FOR LIVING Connected Home Conference 2011

LIGHTING FOR LIVING 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?

LIGHTING FOR LIVING WHY 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

LIGHTING FOR LIVING WHY 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.

LIGHTING FOR LIVING ENERGY 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

LIGHTING FOR LIVING ADMINISTRATION 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

LIGHTING FOR LIVING What 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 1 a • A single dwelling • Either detached house; or • One of a group of two or more separated by a fire-wall • Class 1 b • A boarding house, guest house, hostel or the like • Total floor area not exceeding 300 m 2 • Not more than 12 persons ordinarily resident • Class 2 Multi Residential • Class 10 • Non-inhabitable building or structure • Being a garage, carport, or shed

LIGHTING FOR LIVING ADMINISTRATIVE 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?

LIGHTING FOR LIVING COMPLIANCE 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.

LIGHTING FOR LIVING DESIGN INPUT / TECHNICAL KNOWLEDGE

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

LIGHTING FOR LIVING PART J 6 – ARTIFICIAL LIGHT & POWER • Lamp Power Density or Illumination Power Density • Excluding heaters that emit light • Must NOT Exceed 1. In a Class 1 & Class 2 residential building, 5 W/m 2 2. On a verandah or balcony, 4 W/m 2 3. In a class 10 (garage) , 3 W/m 2 NOTE: where Illumination Power Density is used it may be increased by dividing it by the adjustment factor (refer Table 3. 12. 5. 3)

LIGHTING FOR LIVING CALCULATION METHODS • Two methods • Illumination Power Density, or • Lamp Power Density • Why? It accounts for control systems

LIGHTING FOR LIVING PART J 6 – 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

LIGHTING FOR LIVING PART J 6 – ARTIFICIAL LIGHT & POWER • Lamp Power Density

LIGHTING FOR LIVING PART J 6 – ARTIFICIAL LIGHT & POWER • Lamp Power Density • Ground Floor (5 w/m 2) • 208. 88 x 5 = 1044. 4 watts • Garage (3 w/m 2) • 37. 48 x 3 = 112. 4 watts • Porch / Alfresco (4 w/m 2) • 4. 11 + 10. 32 x 4 = 57. 7 watts • Total allowance for house • 1214. 5 watts

LIGHTING FOR LIVING PART J 6 – 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

LIGHTING FOR LIVING PART J 6. 2(a) – ADJUSTMENT FACTORS • Illumination Power Density Adjustment Factors • Subclause J 6. 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 J 6. 2(a)(iii) requires Illumination Power Density to be used

LIGHTING FOR LIVING PART J 6. 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 1. 2. controlled by daylight sensor, or Lamp efficacy of not less than 40 lumens / watt

LIGHTING FOR LIVING PART J 6. 2(a) – ADJUSTMENT FACTORS

The difference between Residential and Commercial

The Difference between Residential and Commercial continued

LIGHTING FOR LIVING Lighting 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

LIGHTING FOR LIVING TECHNICAL 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/m 2 for interiors, 4 W/m 2 for verandahs and balcony & 3 W/m 2 for garages, etc.

LIGHTING FOR LIVING TODAY So what are the answers? • What do the new requirements really mean for the new home owner? • Optimal versus minimal outcomes? Do they live in the dark? • Is the day of the Down Light gone?
