This page outlines some of the energy saving options available to you. Just call us or email us@hepgrove.co.uk to find out how we can help you start saving!
Occupany Detectors
The use of occupancy detectors makes a considerable contribution to the energy savings in both light management as well as in building services management system.
The occupancy detector switches on light, heating, and ventilation only when needed. The occupancy detector is a motion detector designed especially for ceiling mounting. Its optical system has a coverage angle of 360°, is high resolution, and therefore also suitable for use for detection of office activities, i.e., especially work performed while sitting.
However, in addition to movement, the presence detector senses daylight and artificial light and controls the overall brightness. If this is higher than the required luminous intensity, the artificial lighting is turned off again even though movement is present, or switched on, if not enough daylight is available. Thus, light is only switched on as needed, therefore enabling considerable energy saving potential to be exploited. Alternatively the artificial light is readjusted to only the amount that is needed to meet the predetermined brightness level.
Passive Infared Detectors
A 'passive infrared detector', PIR for short, records radiant heat in a wavelength range of 5-20µm, in which lie the heat radiation of people and animals.
Electronics placed downstream process and amplify the weak detector signals and thus detect movement, which induces the activation of connected equipment. These devices (also referred to as motion detectors or PIR detectors) were originally used in alarm systems and are now more commonly used for controlling lights.
LED's
In recent years LED’s have been widely used in very specific applications, however, the technology is now increasingly being used for general lighting. A wide range of LED Retrofit Lighting now exists, which is very energy efficient, compact, easy to install and has a long life-span and hence low maintenance requirements. There are lots of myths surrounding LEDs, which the industry needs to dispel. For example, fitting LEDs previously required lots of wiring and soldering, but now many retrofit bulbs offer ‘plug and play’ like functionality....you simply just swap out the bulb!
Compact Flourescent Lamps (CFL’s)
Inefficient light bulbs are disappearing from UK shops - they’re all being replaced by energy saving light bulbs. Energy saving light bulbs are compact, bright and available in a wide range of shapes - so the only difference you’ll notice is a drop in your electricity bills. CFL's combine the energy efficiency of fluorescent lighting with the convenience and popularity of incandescent fixtures.
High Frequency Ballast Lighting
High frequency fluorescent lighting ballasts give circuit power savings of some 10%. By combining high frequency ballasts with new high efficiency tubes, suitable luminaries can maintain existing lighting levels at up to 45% reduction in energy use and cost. Retrofit components that electronically convert existing luminaires to high frequency operation enable converted fittings to accept the new high efficiency tubes.
Office Power Management
Millions of tons of CO2 are wasted due to PC’s, laptops and peripheral equipment being left on when the user is away from the works tation. It is possible to save up to 60% of the consumed electricity from a single workstation. Leaving PCs, laptops and peripheral equipment switched on costs you and the environment. Even a modern PC uses over £100 in electricity left on every night of the year. Multiply that by your PC population and you’ re talking a lot of money. With simple changes to how your desk is powered, you can save up to 60% energy per year on a typical working office desk.
