ENE 6, the external lighting issue of the The Code for Sustainable Homes makes allows for two credits to be awarded when security lighting and external lighting complies with a number of requirements.
One credit can be awarded when all space lighting is provided by dedicated energy efficient fittings with appropriate control systems (passive infra red (PIR), ‘dusk to dawn’ daylight sensors or time switches).
Dedicated energy efficient light fittings are fittings that comprise the lamp, base, control gear and an appropriate housing, reflector, shade or diffuser. The fitting must be dedicated in that it must be capable of only accepting lamps having a luminous efficacy greater than 40 lumens per circuit watt. A light fitting may contain one or more lamps. Tubular fluorescent and compact fluorescent light fittings would typically meet this requirement. Light fittings for GLS tungsten lamps with bayonet cap or Edison screw bases, or tungsten halogen lamps would not comply.
Another Code for Sustainable Homes credit can be awarded when all security lighting is designed for energy efficiency and must be adequately controlled such that:
All burglar security lights have:
- A maximum wattage of 150 W; and
- Movement detecting control devices (PIR); and
- Daylight cut-off sensors
All other security lighting must be provided by dedicated energy efficient fittings and fitted with daylight cut-off sensors OR a time switch
Default Cases
If no security lighting is installed, the security lighting Code for Sustainable Homes credit can be awarded by default, provided all of the requirements related to the specification of space lighting have been met.
Dual lamp luminaires with both space and security lamps can be awarded both credits provided they meet the above criteria for energy efficiency
