A WORD FROM UN HABITAT
SAVING ENERGY THROUGH YOUR APPLIANCES
There is a worldwide trend towards
energy efficient appliances and
building materials and the growing
awareness and appreciation of the
environment is set to increase the
demand for green buildings.
Current improvements in design and
technology offer new opportunities
to be competitive in the domestic and
international market. Green buildings
generally offer a more comfortable,
healthier and cost effective solution
for living and working. To go green
means to maintain a competitive
edge in the market.
Energy efficient appliances and the
latest energy saving technology is an
important feature of green buildings
and switching to energy saving
lighting, for instance, helps to reduce
your overall electricity bills by up to
20%.
Today, there is an energy saving
alternative for literally any the
appliances available for household
and commercial use. It is also
necessary to be aware of these new
trends in order to comply with the
legal requirements of integrated
building design.
Energy savings mean cost savings,
while maintaining or improving the
performance of an appliance when
compared to what is considered as
“the normal”.
Energy efficient appliances are
designed to meet three basic criteria:
1. Effective and efficient use of
materials,
2. Energy saving,
3. Low or no toxicity.

A WORD FROM UN HABITAT

The premium, if any, that we need
to pay today for an energy saving
alternative (or sometimes to replace
a still functioning older piece of
equipment) can be expected to
be paid off in a time span that is
significantly shorter than the life span
of the new equipment itself. This
means that investments in energy
saving technology will soon turn into
profit.
