W22 Information/Advertising Display
CONSIDER:
• All appropriate renewable systems including:
- Specify most efficient appliances and luminaires: Efficiency: Grade
A in all cases.
- Significant energy savings over life of equipment and of building can
be achieved.
- Specify most efficient lighting, consider LED and piezo-electronic systems
where available and appropriate.
W30 Data Transmission
CONSIDER:
• CDM regulations suggest designers should consider the health risks
of occupants in use.
• Precautionary principal should apply.
• Use of thin Liquid Crystal Display (LCD) and Thin Film Transistor
(TFT) monitors.
• Use of lead caps on all ports on computer CPU rears but lead is
now seen as a bad material to have around.
AVOID:
• Radiation from infrared and radio transmission from wire-less
computer networks should be considered with some suspicion as a form or
radiation which may have a detrimental effect over prolonged exposure.
• Electro magnetic radiation from Cathode Ray Tube (CRT) computer
monitors and rear connections.
• Electro magnetic radiation from computer Central Processing Unit
(CPU) rear ports.
W52 Lighting Protection
CONSIDER:
• Electricity supply: hand over the building to the Employer (Client)
with a Green Tariff electricity supply, avoiding the financial burden
of the equipment to generate renewable electricity.
• Private networks linking many generation plants in many buildings,
around sites, campus, or towns.
W6 Central Control
CONSIDER:
• Centralised control modules which maximise the efficiency of use
of many sources of low medium and high grade heat and power sources for
optimum efficiency.
• Building energy management systems which warn if door, windows,
rooflights, smoke vents and fresh air and replacement air vents are left
open and loosing heat or cool.
