3 In an office building, lighting accounts for around 39% of the overall energy consumption. By installing lighting controls or low energy lighting such as LED ceiling tiles, this percentage can be reduced and energy savings can be made. 9% 18% 39% Lighting Office Equipment 19% 15% Heating/ Cooling Ventilation Other Office Energy Consumption

4 In association with leading presence detection company Steinel, we are able to offer free energy saving surveys. Before you make the commitment of installing PIRs or presence detectors we can provide you with a detailed report that will tell you exactly how much you will save and which sensor to use. We can leave a PROLog on site that records precisely how much energy a detector will save you. It records the rooms activity and daylight levels over a 2-4 week period.

5 T8 & T12 fluorescent tubes T5 fluorescent or T8 LED tubes Discharge lamps such as SON (sodium) & HQI (metal halide) New LED-integrated downlights, ceiling tiles, low bay and high bay fittings

6 Most modern LED luminaires now have the light source built into the fitting, the LED and driver is integrated into the fitting. This design allows for brighter LED chips to be used, purpose built heat-sinks and the most energy efficient, reliable control gear. The LED is not replaceable, but because they have life expectancies ranging from 25,000 to 50,000 hours they shouldn t need replacing for a very long time. For example the ASD LED high bay featured in this guide would last for 21 years if used for 9 hours per day, 5 days per week. No lamps would need replacing and no maintenance would be required throughout this period. Efficacies of 103 lumens per watt can be achieved. Almost double the requirement of Part L2.

8 Our LIF qualified lighting team can advise you on the most suitable light fittings to use, to meet the needs of any room or environment: For Schools and Colleges you may need to meet Lighting Guide 7 (LG7) design requirements or UGR19 for offices. Hotels and retail shops; recessed and surface modular fittings. Suspended fittings, uplighters and downlights. Sports halls, large retail outlets, factories and warehousing; low bays and high bays.

9 Our Lighting Engineers offer a complete lighting design service using their industry experience and Relux software. Energy surveys to establish how much energy you are using and where you could make savings. To offer the type of lighting that best suits your needs and budget. Should it be LED or T5 fluorescent? To provide if required a complete package. Survey, Design, Supply and Installation.

10 All Commercial Buildings and Schools are covered by Part L2 of the Building Regulations. All installations to Existing Buildings under 100m 2 are not notify-able but should meet regulations. All non-dwelling Buildings should be provided with energy efficient services and controls. Part L2 is awarded to the building not the lamp or luminaire and account is taken into energy saving controls. The overall efficiency of the building should achieve lighting efficacies of at least 55 lumens per watt. As detailed in Parts L2A and L2B energy meters should be installed, so that at least 90% of energy can be calculated by category, e.g. lighting, heating etc.

11 Lighting must provide the following minimum average initial efficacy levels. 1. General lighting in Office, Industrial and Storage Areas: 55 Lumens per circuit-watt. 2. General lighting in other types of space: 55 Lumens per circuit-watt. 3. Display Lighting: 22 Lumens per circuit-watt.

12 Exemptions to Part L Building Regulations include: Specialist Process Lighting Emergency Lighting Specialist Lighting such as Stage Lighting and Illuminated Signs.

13 Our Lighting Engineers can work from Autocad drawings and scaled plans to design your installation. We can arrange a site visit if there are no plans available. Ensure the design meets your needs, is energy efficient and make sure it complies with Part L2 of the Building Regulations. Use fittings that meet with the requirements of the government Enhanced Capital Allowance scheme. So you can claim a 100% offset against your Corporation Tax in the same year!

14 Want to cut energy consumption and start saving but don t have the funds available? We can assist with an interest free carbon trust loan. The loan can even include installation costs! Start reducing energy costs now, don t wait!

15 You don t always have to install expensive low energy lamps or luminaires to save energy. If a room is not always occupied or if it has sufficient daylight for most of the day, energy saving controls should be considered: Absence Detectors such as PIRs and microwave sensors make sure that light is only used when it has to be. Lux Sensors can be installed to dim and/or turn off lighting during periods of absence and/or sufficient daylight.

16 Lighting Control Systems such as the Lutron GRAFIK Eye QS adjusts lights and shades for any task or activity at the touch of a button. You ll save energy while meeting the aesthetic, functional, and regulatory needs of any project or space. Groups of luminaires can be looped together in a room and controlled by their own specific sensors or timers using DALI addressable ballasts and Lutron control panels.

17 8FT T12 Fluorescent tubes are now banned by the EU as they are not energy efficient. LED technology is not always the most cost effective solution. We recommend installing new 2x54W T5 fluorescent fittings. They can be supplied in the same 8FT format to make installations easier and to match the existing set up. To save further energy they can also be supplied with built in presence detectors that dim down to 10% when an area is vacated. They won t turn on if sufficient daylight is present.
