“The idea is to provide the
responsible person with preventative data regarding the ongoing performance of the associated equipment and to highlight any potential problems or drop in performance,” said Joppi. He added: “In a rapidly-changing
world where technology is evolving on a daily base and impacting on our personal lives, it is logical to presume that more intelligent technologies will increasingly find their way into public buildings such as hospitals. “If we have the opportunity to help
The first stage of installing emergency escape lighting is consultation and design
system installed throughout the building, which it was claimed had fallen below standard and was not being properly managed by the appointed person. When specifying solutions, Rene
Joppi, commercial director at Mackwell, advises: “Before embarking on design, a full risk assessment must be undertaken to determine the areas in the hospital which have a requirement for emergency lighting. This will include escape routes, open areas, points of emphasis such as locations of essential fire safety equipment, and any areas deemed as high-risk task. “An accurate and compliant
emergency lighting scheme design, undertaken in line with the initial risk assessment, and the emergency lighting code of practice, BS 5266-1, and its accompanying standards; BS EN 50172 and EN 1838, will ensure the areas covered are illuminated correctly and adequately.” But, he warned: “In many cases the
risk assessment is not adhered to correctly, partly due to budgetary constraints and unhelpful timescales. “As a result, the lighting levels can be
compromised as lower-quality, inferior fixtures are used and the number of fixtures specified is reduced. This can lead to poor uniformity and ‘dark spots. “Similarly, a poorly-designed escape
route with poor-quality or incorrect exit signage can lead to confusion and ambiguity in an emergency escape situation.” And, for the emergency lighting to
remain compliant throughout its designed lifetime, there are several factors to be considered. “The performance of components is
heavily dependent on how they are operated and maintained,” said Joppi. “The rechargeable battery, for
instance, is a critical component, but it can be highly susceptible to abuse through neglect, exposure to high temperatures, and overcycling etc.”
Intelligent technology Maintenance is also crucial. For instance, if placed in a dirty environment, the light source may not be delivering its declared luminous flux, while any changes to building layout, structure and internal fabric can also have an impact on ongoing compliance. To address these issues, the very-latest
products routinely offer inbuilt diagnostics, for example on-board software that can monitor battery health.

in brief
• New diffuser reduces energy use A new LED lighting solution has been launched aimed at helping hospitals to reduce their energy use. Fitzgerald Lighting has unveiled the dust-limiting, wipe-clean diffuser, the LED Municipal. The product has a constant output driver that uses colour temperature 850 as standard and saves users 66% in energy costs. It also has a curved body shape and for extra security and tamper resistance. Optional features can also be specified including 1–10V dimming, DALI dimming, and integral three-hour maintained emergency lighting.
