and designed to provide best value to our clients.
Electrical Efficiency
Together with good maintenance practice, energy efficiency is
always a feature of our designs. We are also able to advise on
energy conservation and maintenance reduction measures for existing
installations.
Large savings can be made on electricity bills by the use of modern
lighting technology and energy saving devices.
Listed below are some common methods used to reduce electricity
bills:
- Installation of high frequency luminaries. This modern type of
luminary can be up to 30% more efficient than the older type of
fluorescent Luminary. A further benefit of this type of luminary is
that the frequency of light change is so fast it is more
comfortable on the eyes making for a more pleasant work
environment. High frequency luminaries can be used with day light
automatic dimming.
- A light sensor automatically adjusts the light output level to
allow for day light in a room. In a bright day light room, the
luminaries will drop down to below 30 % output, making great saving
on electricity bills. This method is very simple and requires no
action from the building users but saves on electricity all year
round.
- Installing Presence sensors to rooms. With this method lights
are only on when required. This can lead to large savings on energy
bills. Combined with modern luminaries described above and day
light dimming, very large savings can be made (approximately 40-50
%).
- Replacing any old Tungsten luminaries with fluorescent type
luminaries. A fluorescent luminary uses about a quarter of the
electricity of a equivalent Tungsten type lamp.
- Installation of lighting control systems to large buildings.
This type of system can give the landlord great control over the
way lighting is used in a building. Lighting can be timed to come
on and go off at certain times and be adjusted to suit the needs of
the building users. The down side of complex systems is that they
can be expensive to repair or change.
- Thermostatic control of any electric heaters or operation by
presence detectors/time switches. This can help minimise wasted
expensive use of electric heating. Generally heating by electric
heaters is not cheap (unless by Economy of Peak storage Heating).
Large bills can be run up quickly with bad controls on electric
heaters.
Lighting design
Lighting design is a area of the construction/refurbishment
process that often does not get the recognition it deserves.
The atmosphere in a room can be drastically effected by the type of
lighting installed and the lighting design levels.
Get it wrong and people will often just not be happy
working/resting in that area or will be unable to work safely or
effectively.
Lighting designers have to be aware of various regulations such as
'CIBSE Lighting Requirements' which details methods of lighting and
recommended lighting levels in different environments.
New Lighting schemes now have to comply with building control
guidelines on energy efficiency.
Detailed below are some common lighting design
considerations:
1. Rest Areas
If any area is being designed for people to relax in, it is
important lighting design levels are not to high. Localised areas
of higher lighting level can be provided for reading etc by the use
of down lighters with background lighting possibly being provided
by uplighters. It is very important to minimise glare as this will
cause stress to the eyes and make relaxing very difficult.
2. Computer Rooms
Areas designed for use with computers should comply with CIBSE
LG3/LG7 guidelines, which basically aim to ensure glare from
lighting does not reflect on VDU screens. The recently updated LG3
guidelines aim to ensure that some light is thrown on the ceiling
and walls to prevent the 'dark patches/high contrast effect'
previously associated with lights designed to be used with
computers.
3. External Lighting
This can either be designed for effect or to provide security
lighting or both. many studies have shown that good lighting in
public areas is a very effective way of reducing crime and also the
fear of crime.
Buildings such as town halls churches etc can have lighting schemes
designed for them that can really make them stand out at night time
and look quite dramatic and make an areas more attractive to
visitors.
4. Energy efficiency
Provision of suitable Lighting systems is now recognised as an
ideal way to improve the energy efficiency of a building. Modern
high frequency luminaries used with lighting controls (automatic
day light dimming or PIR sensor switching) can greatly reduce the
cost of lighting a building with savings of up to 40 to 50%
compared with older lighting methods.
5. Emergency Lighting
Public buildings, shops etc have to have emergency lighting systems
installed to meet British, European standards and Building Control
requirements.This is to enable safe escape in emergency
situations.
As can be seen from above Lighting design is a deep subject in its
own right with many engineers specialising in it exclusively. With
modern lighting and lamp technology improving all the time the
opportunities are getting greater. Putting in the right lighting
design input in the beginning of a project can benefit people for
years to come. Please contact the Electrical Services Manager if
you require any further information regarding this subject.
Electrical Security
Security considerations for building managers seem to be on the
increase all the time. As an electrical services group, we
regularly have to deal with these issues.
Detailed below are some of the common problems we deal with and
some solutions we recommend/implement. It is very important to give
a problem the attention it needs and consult specialist advice to
achieve the best results in this area.
With the wrong specification such as with CCTV installations
large sums of money can easily be wasted producing systems that do
not achieve the desired result and so investing in proper
planning/research is essential to ensuring a good outcome!
The topics below have only be covered in brief and are only
intended as a quick guide. Please do not hesitate to contact the
Electrical Group Manager should you have any queries or if you
would like some advice on a relevant security/safety issue.
CCTV
The installation of camera systems has been one of
the fastest growing areas of security work, with Britain having one
of the highest numbers of cameras per person in the world.
The use of CCTV systems has in the last couple of years become more
tightly regulated, with systems having to comply with the Data
Protection Act. This involves amongst over things having the CCTV
system registered with the Data Protection Offices.
Suitable warning notices must be displayed (with owners contact
information), and Data storage/use must conform to Data Protection
Requirements. This is to provide an audit trail if video evidence
is required in a court of law and to provide safe guards against
its miss use.
Further information on the Data Protection Act/CCTV is available
from the Home Office web site or Contact internally Garry Hobbs on
0203 373 1838 or email
garry.hobbs@newham.gov.uk.
Reasons for Installing cameras
Installing a CCTV system can provide a means of remote monitoring a
building/area. In Newham many sites are linked backed to the Newham
Control Centre where sites can be regularly monitored by trained
personnel all day, seven days a week. This facility can be combined
with high tech facial recognition software, where the system can
alert staff to the presence of particular individuals.
The CCTV system allows images to be kept on tape or stored
digitally which can be used in prosecutions if the images conform
to standards laid out in home office rules. This is a good reason
to ensure only suitably skilled/qualified persons are used to
design CCTV systems. A bad design could lead to the images being of
poor quality and useless to the C.P.S.
Installing CCTV can provide reassurance to tenants/members of
the public. It can also act as a good deterrent to criminal acts or
anti social behaviour and should be seen as one tool helping to
deal with these problems. Where CCTV is installed it is generally
essential to look at the lighting conditions in the areas involved.
This will be required for good pictures, but also it has been shown
that good lighting significantly helps to reduce crime and fear of
crime.
You do not want a camera staring into the sun.
Digital CCTV Systems
Digital Systems are now available where the recorded images are
stored on a hard drive as opposed to a video recorder. This reduces
allot of the management problems associated with the VCR system, ie
changing tapes etc. Recorders can be sized to allow a months
recording to be stored. After this the recorder will start to over
write the stored data with new.
Intruder Alarm Systems
Intruder alarm systems are installed to most council
buildings.
These generally operate by the use of Passive Infra Red (PIR)
detectors that detect when a person comes in their range and
triggers the alarm. Door and window contacts operate the alarm when
activated. Most intruder alarms will be connected via a dedicated
phone line back to the Newham Security Control Centre, where the
alarm is monitored.
False alarms can some times be a problem, which can be caused by
amongst other things insects getting inside detectors etc. Again,
great care should be taken when designing an Intruder system to
ensure detectors cover all relevant areas.
A planned break in could be via a route not protected. Detectors
should generally cover all Staircases and all entry points. Any
room with valuables with window access generally should be
protected.
Areas such as computer rooms may need special protection. Panic
alarm switches can be connected to modern Intruder Panels, which
can be used at reception desks and offices where people are often
alone and vulnerable.
Controlled Access Systems
The electrical services group has designed and arranged the
installation of many 'access control' systems through out the
Borough.
These have been installed to housing blocks, some office areas and
schools.
Most of these schemes involve key fob access systems. The tenant
is issued a small plastic fob, which when presented to a special
box automatically releases the door magnets or locks.
Tenants can automatically release the door to let in guest to
the block, once they are sure it is safe to do so. When a tenant
moves away from their flat, their fob can be removed from the
system. Fobs can also be deleted from the system if they are
lost.
These systems tend to be very reliable as there are no moving
parts as such. Problems experienced are generally due to
vandalism.
It is important that these systems are connected to any local fire
alarm system to ensure safe access from the building is provided in
the event of a fire. Schools are increasingly having access control
systems fitted to allow them greater control over whom enters their
buildings.
Electric Gates
Motorized electric gates are increasingly being used by schools and
office accommodation areas to control access of cars to parking
areas. These can be Fob controlled as mentioned above allowing
control over parking in restricted areas. The gates can be linked
with intercom facilities to a school office, allowing remote
operation.
Panic Systems
There are a number of different panic alarm systems on the market
today. Many modern intruder alarm panels have the facility to have
a number of panic alarm buttons connected to them. The panel can
either give local warning or send a message to a control centre via
a phone line.
Wireless version are available that are often used in classrooms
or social services properties. The panic switches can be
repositioned regularly to their best position with ease. Pendants
(panic devices) can be supplied with the system that can be worn by
play ground staff etc in schools.
Design Issues for panic Alarms
Typical considerations:-
What kind of response is required when a panic switch is
activated? A loud noise local to the activation (such as a
electronic) sounder could cause panic, leading to maybe serious
injury. A flashing beacon with a discrete sounder in a near by
office, can give the opportunity for help to be got to the incident
with the minimum of panic, hopefully enabling a situation to be
resolved peacefully.
The position of the panic switch could be critical, and is worth
giving great thought to.You do not want to have to run across the
room to get to it!
Connection to a Control Centre
If you are left working alone, you will want the Panic activation
to be seen some where, ideally a control centre such that Newham
Security provides. They can then arrange for appropriate action to
be taken upon an activation.

more information, please do not hesitate to contact the Electrical
Services Manager John Ficken on 0203 373 8465 or email
