UNIT 4: ENVIRONMENT MANAGEMENT SYSTEMS<br />
099<br />
The Hong Kong Hotel, Hong Kong has reduced water consumption by 20% by<br />
installing aerators in bathroom outlets and eliminating the use of running water<br />
for cleaning.<br />
In Canadian Pacific Hotel and Resorts hotels, water outlets and distribution<br />
pipes are regularly checked for leaks, aerators are installed in taps, low-flow<br />
showerheads and low-volume cisterns are used in bathrooms, and photoelectriccell-operated<br />
toilets and washbasins are used in public facilities. At one of<br />
the chain’s hotels, the Hotel Vancouver, a solution based on baking soda and<br />
salt is used to purify swimming-pool water. This has reduced chemical use and<br />
associated costs, and made handling and disposal easier.<br />
ENVIRONMENT MANAGEMENT PROGRAMME FOR ENERGY<br />
Energy efficiency not only reduces fuel and electricity bills, it also increases the<br />
overall comfort of the property. Energy management may be divided into two main<br />
areas:<br />

Maintenance or ‘Good Housekeeping’ Options<br />
• Loft insulation can help prevent condensation and mould, and can<br />
reduce heating bills by almost 20%. Insulation materials include<br />
mineral wool and brown cellulose fibres. A thickness of 15 to 20 cm<br />
should be ensured for maximum energy efficiency. As insulation makes<br />
the loft area colder, hot water tanks and pipes in this area must also<br />
be insulated.<br />
• Shut down power in sections of the building that are not in use.<br />
This can be done through the use of Building Management Systems<br />
(BEMS), discussed later in this section.<br />
• Insulate all hot water tanks, pipes and boilers.<br />
• Seal gaps in walls, windows, doors, roofs and floor to control heating/<br />
cooling loss and penetrating damp.<br />
• Make visitors aware of the importance of energy conservation. Invite<br />
them to switch off equipment and lights when not required.<br />
• Match the size of the appliances to demand requirements. Oversized or<br />
undersized equipment wastes energy.<br />
• Train staff to use less hot water and to save energy by switching off<br />
equipment when not needed.<br />
• In the kitchen, match pan size to hot plate/burner size. Defrost food at<br />
room temperature and not in hot water.<br />
• Maintain hot water in taps at 50°C.<br />
• Use translucent lampshades to optimise light output.<br />
• Open and close curtains to maximise and minimise heat gain as<br />
required.<br />
• Ensure timers and controllers are set according to the degree-day<br />
thresholds and levels of activity inside the property.<br />
• Ensure boilers and chillers are regularly serviced to maximise<br />
efficiency.
