compliant

For a new or existing non-domestic building, all office, industrial, and storage spaces must have lighting that averages at least 95 luminaire lumens per circuit Watt or should observe a LENI calculation that follows Appendix B of Part L. Other spaces within non-domestic buildings must average at least 95 lamp lumens per circuit Watt for general lighting, or 80 light source lumens per circuit Watt for display lighting. LENI The Lighting Energy Numerical Indicator (known as LENI) offers another way for non-domestic buildings to comply with Part L2. LENI is a more complex calculation that requires the designer to calculate the performance of the lighting in terms of energy per square metre per year. This figure also takes lighting control into account, and is therefore based on a lighting design that takes into account all of the user’s needs. Recommendations for appropriate illuminance values and other lighting requirements are found in BS EN 12464-1:2011 ‘Light and Lighting - Lighting at work places - Indoor work places’. Much like the standard Part L2 requirements, there are separate allowances for display lighting. Lighting Controls Lighting controls should follow guidance found in BRE Digest 498 ‘Selecting lighting controls’. For general interior lighting, areas should avoid unnecessary lighting at times when either daylight levels are sufficient or the spaces are unoccupied. Areas should also feature local switching that’s accessible to users. Display lighting should be controlled on dedicated circuits. Unoccupied spaces should have presence detection and occupied spaces should have daylight sensing.

Reasonable provision should be made for a dwelling to benefit from energy efficient lighting in the following instances: 1. A dwelling is extended 2. A new dwelling is created via change of use 3. The lighting system is being upgraded as part of a re-wire 4. New builds Fixed Interior Lighting In any of the above instances the lighting must have a minimum of 75 light source lumens per circuit Watt. Any single installed switch should operate no more than 6 lamp units, with a total capacity no greater than 100 Watt. Internal light fittings should have zones of local control, which may be manual, automatic or a combination of both. Fixed Exterior Lighting Exterior lighting should have both of the following: 1. Daylight sensing 2.<75lm/W = automatic sensors/>75lm/W manual control.

Thermoplastic Fire Rating TP(a) and TP(b) The Building Regulations 2010 Approved Document B - Fire Safety Aurora’s LED Panel range TP tests were carried out by the LIA and the results detail the burning rate of a thermoplastic material. The tests that were carried out on each material samples were in accordance with BS 2782-0:2011 Method 508A Rate of burning, Laboratory method to determine whether the thermoplastic is TP(a) or TP(b) rated according to The Building Regulations 2010 (volume 2 - Buildings other than dwelling houses B). TP(a) is awarded to any material, when tested using Method 508A above, where the test flame extinguishes before a

certain point on the test sample and any flame or afterglow self-extinguishes within 5 seconds of the source of ignition being removed. TP(b) is awarded to any other material at a thickness between 1.5mm and 3mm that, when tested using Method 508A above, has a maximum rate of burning of 50mm/minute. For more detailed information on the application of TP rated materials, please see Building Regulations Approved Document B - Volume 2.
