Definition
51 T5 fluorescent tube
T5 fluorescent tube is 16mm (5/8”) in diameter and is more efficient than the
conventional T8 or T12 lamps.
52 Thin film photovoltaic
(TFPV) panels
A thin-film photovoltaic panel is made by depositing microscopically thin layers
of photovoltaic and conductive materials directly onto a pane of glass or other
substrate.
53 Total harmonic distortion Total harmonic distortion may lend to equipment failure and additional power loss.
54 UVC emitters
A UV emitter is a device to emit ultraviolet energy on the “C” wavelength which is the
most germicidal in the UV spectrum.
55 Vinyl
Vinyl is a plastic made from polyvinyl chloride (PVC). It emits gases and is potentially
harmful to humans, and can cause irritating respiratory illnesses such as asthma.
56 Volatile organic compound
(VOC)
Volatile Organic Compounds (VOCs) are a diverse group of organic compounds
that evaporate at room temperature. In a typical indoor environment, there are more
than 100 compounds that can be classified as VOCs emitting from sources such as
building materials, cleaning agents, cosmetics, waxes, carpets, furnishings, laser
printers, photocopiers, adhesives, paints and lacquers. Certain VOCs at high levels
are toxic and have adverse effects on the central nervous system, liver, kidney
and blood of human bodies. Hypersensitive individuals can have severe reactions
to a variety of VOCs at very low concentrations. Exposure to compounds such as
benzene for long periods may also increase the risk of cancer. It is desirable to
reduce exposure to VOCs, as the toxicological and sensory effects of VOCs are not
completely known.
57 VOC products
Products containing VOCs can release these chemicals when they are being used
and when they are stored. An odour may be noticed when using these products.
Product labels often list VOC ingredients and recommend that they should be used
in well ventilated areas. Ventilation means bringing in fresh, outdoor air to mix with
indoor air.
58 Waste management plan A plan that lists the work processes or activities that will generate construction waste
and demolition materials during the course of the work and describes the measures
to reduce/ minimise that waste.
59 Water cooled chiller
Water-cooled chiller is equipment that includes an evaporator, compressor,
condenser and regulator control, and which serves to supply chilled water. The heat
absorbed by the refrigerant in the chiller is expelled into the outdoor environment by
evaporation through cooling towers, or by seawater discharge to the sea.
