From the
ome interesting stats have emerged in a joint survey by the Electrical Contractors’ Association, Chartered Institution of Building Services Engineers and the Scottish electrical trade body, SELECT.
It appears that there is still some way to go before end-user clients fully grasp the Internet of Things.
The survey revealed that more than half of the respondents felt that the lack of clear advice and knowledge was a barrier to installing connected technology.
I can’t help feeling that somewhere along the line, someone is missing a trick. Interestingly, six out of 10 respondents said that they had no plans to evaluate or install connected technology. Connected technology is undoubtedly a fantastic salvo in the battle to reduce energy bills and create more efficient buildings. And installers can only benefit from the expected evolution in this kind of technology.
But with consultants, engineers, end clients, local authorities and facilities managers citing lack of
awareness/knowledge as a barrier, clearly work needs to be done. One useful pointer is that over the next five years, respondents said the technologies most likely to be installed in buildings will be CCTV and security (78 per cent), heating (74 per cent), fire systems (69 per cent), and BEMS (67 per cent).
The ECA intends to work with the wider industry to help building clients develop and implement plans to take advantage of these commercial and technological opportunities.
If this is to be an annual survey, I look forward to seeing how the stats stack up next year!

TALKING POINT By Phil Marris, Managing Director at Jaga Heating Products UK air pollution – a problem that cannot be ignored
he UK – alongside Germany, France, Italy and Spain – has been issued a final warning by the European Commission for failing to address breaches of air pollution limits for nitrogen oxide. EU Member States have been repeatedly asked to implement air quality plans to safeguard public health, but the requests have fallen on deaf ears.
T
Just recently, it was recorded that London air was far worse than in the notoriously polluted Beijing, hitting a peak of 197 micrograms per cubic metre for particulate matter on the Air Quality Index.
In a survey of 1,670 adults, 58% believed that the current levels of air pollution in the UK are either harmful or very harmful to overall health.
A University of Surrey study says London tube commuters are most at risk – being exposed to more than eight times as much air pollution as those driving to work. Whilst motorists were exposed to 8.2mg of the harmful pollutant PM10, tube travellers experienced 68mg. Such exposure can lead to complications including breathing problems and respiratory diseases.
Whilst there has been much dialogue concerning air pollution, little is said about the importance of excellent Indoor Air Quality (IAQ). Commuters spill out of tube stations and are likely to work in offices all day. But working inside doesn’t protect you from air pollution. CO2 levels can easily increase in any building with little or no ventilation.

The outcome – a stuffy, polluted environment which is likely to hamper concentration and productivity of a building’s occupants.
Solutions and Considerations
Naturally, the answer would be to invest in a ventilation solution which can restore excellent IAQ. Simply opening a window cannot effectively control CO2
levels,
and will let in the polluted, unfiltered air.
Instead, Demand-Controlled Ventilation (DCV) is becoming an increasingly popular choice. An intelligent and automated system, DCV works with sensors that instantly detect rises in CO2 levels in a room, reacting instantly to draw fresh filtered,
pre-heated or cooled air in whilst the stale air is then extracted. It is critical that office workers around the country are not just protected from outside air pollutants, but that the conditions within their workplace are also excellent.
Almost 70% of office workers believe that poor air quality in the workplace is negatively impacting their day-to-day productivity and well-being – a problem that can no longer be ignored.
