Great care must
be taken when
interpreting these
numbers, as they
vary from country
to country based
on the source of
raw materials,
production
processes and
transport
distances.

3.3 The Use of Environment Management
During Occupation
Sustainable building design is not the end, just the beginning. Buildings have
to be used and maintained to optimise the benefits of the sustainable features
incorporated in them. Lower energy use, material use and waste output during
occupation also facilitates the implementation of EMS.
A few examples of environment management technologies, fittings and appliances
are given below. Many of them have been discussed earlier in this Unit and in
Unit 4:
WATER RELATED TECHNOLOGIES
• Grey water reuse systems;
• Water-saving products such as low-flow showerheads and tap aerators;
• Low-flush toilets and vacuum toilets;
• Waterless urinals;
• Alternative sewage treatment systems;
• Dishwashers that operate on 5.3 gallons (as opposed to 12.5 gallons)
and 40% less energy than conventional models;
• Washing machines and dryers that use 14 gallons per full cycle;
conventional models use 50 gallons of water and 50% more energy.
