Here we go again... this time with smart lighting! We present the first issue of ‘Smart Electrician’ of 2016, designed for all of you who want to go beyond traditional electrical installation and delve into the exciting world of new technologies that are already changing our world.
Smart Electrician The Internet of Things for Electricians
This is the world of the Internet of course, but also that new buzzword, the Internet of Things (IoT), its industrial counterpart, the Industrial Internet of Things (IIoT), as well as smart and connected LED lighting, OLED displays and other marvels. There are also some new and potentially very exciting ways of making LEDs much more energy efficient. This involves nanotechnology techniques and you’ll find out more in this issue.

This edition is much more about smart and/or connected lighting, some also taking in the IoT. It is the very fact that LED lighting is digital that is now making the real waves. Being digital, LEDs are controlled very differently from conventional lamps – and in ways that are opening up entirely new possibilities. One of these is connectability, leading to lighting’s easy integration into the already massively growing IoT. Indeed, Philips considers lighting to be ‘the foundation of the IoT’ – well, it’s certainly one part of that foundation. So take a look at this issue of ‘Smart Electrician’, which reports on smart lighting, the voice control of lighting and switches, the LED revolution, how lighting can now send promotional messages to shoppers, personalised lighting experiences, connecting lighting to Apple’s watch, plus that exciting nanotechnology development.

all interact with each other to deliver the commands that have been programmed into what is effectively a bespoke system. Because everything is set from the computer via a simple program, it is possible to change or modify the settings of any of the devices and units connected to the system – such as creating or modifying lighting mood scenes and varying the time it takes dimmers to fade up or down. It is also possible to add and extend units at any time, which means that there is ultimate flexibility to adapt the system to suit changing needs and requirements. With the touch of a button it is possible to regulate the heating and lighting, close the shutters and gates, see who has arrived at the front door, dim the lamp in a child’s bedroom and set the coffee machine percolating. The options are endless. Whichever system provides the required solution, what they have in common is a means of reducing costs and saving energy, and with the 2016 deadline that will require all new dwellings to be ‘zero carbon’ looming, it is within everyone’s interest to embrace the technology that is helping to shape the future of our homes and work places.

Regulation 421.1.201 in Amendment 3 to the wiring regulations is not just about non combustible enclosures for consumer units, this new regulation requires non combustible enclosures on similar switchgear assemblies too. “Similar switchgear assemblies� includes switchgear that is used for the same fundamental purpose as consumer units i.e. circuit protection applications within domestic household premises. This is why Wylex have introduced several additions to their Amendment 3 range. As well as the NM range of consumer units there’s the range of Meter Cabinet Consumer Units (previously known as Skeleton Units) in full non combustible all metal enclosures. These bespoke units are designed for use in high rise, and similar applications where the electricity meter is housed within a cabinet outside the dwelling and the consumer unit is located in the same enclosure in the space above the meter.
In addition there is a brand new range of Domestic Switch Fuse Units in all metal non combustible enclosures. These products are used wherever large buildings are being converted into several apartments. These are ideally suited for sub main circuit protection applications in 60A 80A & 100A ratings. To further enhance the fire safety standards that are intended by regulation 421.1.201 Wylex, has introduced a range of accessories including intumescants, flame retardant grommets, non combustible blanks & mains tails glands All Wylex domestic circuit protection units meet the requirements of the relevant product standards (BS EN 61439) and the latest requirements of BS7671 Wiring Regulations including Amendment 3.

ISSUE 01 | 2016
Sustainable technologies can mean potentially big new business opportunities for electrical contractors and installers! Today, sustainable ‘green’ technologies are becoming ever more important in the drive to reduce CO2 emissions to atmosphere whilst saving energy and money. Sustainability effectively means development that meets the needs of the present without compromising the ability of future generations to meet their own needs, and in electrical terms, it means sustainable equipment and products that can be fitted and commissioned by electrical contractors and installers into existing buildings or into modern sustainable buildings and related environs. Such equipment is quite broad, including modern high efficiency heating systems, heat pumps, solar photovoltaic (solar PV) arrays, wind turbines, micro- and mini-CHP units, biomass boilers, fuel cell systems, whole house ventilation and heat recovery systems, ventilation fans having advanced energy saving motors, the latest energy saving lighting systems (including of course LED), as well as smart homes and buildings. Such technologies can provide large costs savings to home and building owners, as well as helping to reduce those all-important carbon emissions into the atmosphere, and it is here that electrical contractors and installers can often find new business. A mere six years ago, buildings accounted for about 43% of all the UK’s carbon emissions. This is reducing but so far not by that much. So buildings and other developments can also damage the environment through poor waste management or inefficient use of resources. This is such an arresting figure that both the EC and the UK Government have been trying to improve things with a raft of legislation, regulation and incentives all aimed at reducing the carbon emissions from buildings. In this article, we look at some very clever technologies – at least one of them genuinely new – that help to reduce the costs of energy usage, part of that cost being the damage that carbon emissions cause, which have their own costs. The EU’s strict 2020 renewable energy targets for member states are looming, yet countries such as the UK, the Netherlands and France are not currently meeting targets. CXC Global believes that this means business benefits for contractors, here
and in those other countries. Schneider Electric has been participating in the government’s £9.5m initiative to modernise the UK’s energy infrastructure so that it will be able to accommodate millions of homes fitted with solar PV and electric vehicle charging facilities. The most recent amendments to Part L and Part F of the Building Regulations and their accompanying compliance guides are shaping ventilation design in sustainable homes. Then there’s Dimplex’s new, innovative and simple solution for energy storage. Called Free-E, this works with the homeowner’s solar PV installation to heat the hot water cylinder for free. This clever energy management system diverts surplus energy generated by solar PV installation to the immersion heater in the domestic hot water tank. Crucially, says Dimplex, it opens up a huge market of existing solar PV users to contractors. Two very interesting techniques concerned with energy saving, energy sharing and sustainability come from Tesla Motors, the electric car manufacturer, and a Dutch-based company, Nerdalize. The former is using its extensive electric car advanced battery expertise to branch out into energy storage. The company’s rechargeable lithium-ion batteries will power homes and businesses to store solar energy and serve as a back-up system for consumers and businesses during blackouts. Such ‘stationary storage’ techniques will be crucial for the greater take-up of ‘green’ energy sources. The latter, on the other hand, has devised a way to decentralise data server farms to provide free heat into domestic (and other) environments…in essence, this is a data centre spread across many homes and businesses, using their local computers as radiators. Yes, really, and it’s been nicknamed ‘nerd power’! Take note of the IoT…. Many Smart Electrician readers will now be becoming aware of the fast growing ‘Internet of Things’ (IoT). This is a huge topic in its own right and the IoT will have enormous effects on our lives and on businesses. Suffice to say for now, that the IoT has the potential to make even larger energy savings in homes and other buildings, so it is essential to start learning about it now. ■
