Property developers should embrace the challenges posed by South Africas
electricity crisis and introduce energy efficient measures in new housing
developments.
This is the call from Fanie Lategan of the Chas Everitt International
Western Seaboard office. It is evident that measures must be taken
across a broad front, not only in the immediate future, but also with
a view to make better use of energy resources that are set to become
scarcer and more expensive.
Lategan says electricity shortages will affect SAs economic prospects
and it is therefore vital that all sectors do their utmost to conserve
electricity. In this regard, property developers can make a substantial
contribution by including energy efficient features in as many new houses
as possible. They now have a great opportunity to influence the way
consumers view and use electricity in a country that has become used
to cheap energy.
In the past, many available energy-efficient methods and devices
were not specified in new construction because of cost and other factors.
With electricity scarcity set to continue for several years, and tariff
hikes an inevitability, many of these will start making economic sense
- and will no doubt enhance the desirability of energy efficient homes
among consumers.
Lategan says not all measures are expensive. Solar power is widely
touted as sustainable, but costs are still high. However, age-old basics
such as positioning buildings to face north and to ensure adequate natural
ventilation, should not be negotiable and should take precedence over
cosmetics such as, for instance, positioning buildings to capture particular
views.
Insulation, such as the many proprietary brands of ceiling insulation,
and even double glazing of windows, which is normally found in colder
northern climes, will go a long way in cutting electrical consumption
for heating and cooling. He also adds that roof paint that reflects
heat away from surfaces is locally available and that the so-called
green roof concept, where living plants are set into a growing
medium on top of the roof surface, is gaining renewed acceptance worldwide
thanks to considerable energy savings in air-conditioning.
Lategan suggests that developers also pay particular attention to hard
landscaping in housing complexes since large expanses of brick or concrete
act as heat traps. Heat islands, a term describing the phenomenon
in which urban and suburban temperatures are 1 to 6 degrees Celsius
hotter than nearby rural areas, are created by such landscaping, as
well as conventional roof surfaces.
Other possibilities include making provision for gas appliances, fitting
automatic timers to electric geysers or installing solar water-heating
systems, insulating plumbing and installing window shutters. Homeowners
will probably make some, or hopefully many, of these changes to their
existing properties and in future, buyers of new properties are likely
to favour developments that already include such features, Lategan
says.
