ELEMENT:
Philips, fluorescent, high energy fitting with low mercury content.
AIM:
The aim of the electric lighting system of the house is to provide adequate
illumination, but at the same time reduce the heat gain to the house generated
by the light fittings, thereby maintaining the effectiveness of the natural
ventilation. Fittings and lamps were selected to give the required illumination
for a minimum amount of energy use. The lamps selected have less hazardous
materials in their construction. Walls are light coloured to increase
internal light levels.
STRATEGY:
Conserve Energy
The electric light system complements the natural day lighting and operates
interactively with it, complementing rather than supplementing or substituting
for daylight.
The reflective surface of the walls and roof (by being light coloured)
increases the reflection of light inside and outside.
The low heat output from the fittings reduces the heat gain and so helps
to moderate the internal air temperatures. This means less heat for the
passive cooling system to remove and thus better thermal control.
The use of low mercury fluorescent fitting lamps have a reduced quantity
of mercury in the lamps. Mercury is a toxic material which is necessary
for fluorescent lamp production but can get into the human food chain.
The effective ballust system controls lamp flicker common to fluorescent
lighting which is psychologically disturbing to occupants.
