were created to install the fixtures.
One of the design criteria was to have
no upward light spill at night to prevent
disturbance to the surrounding fauna.”
In researching the lighting needed
for horses, LDP discovered that
equine vision is sensitive to shorter
wavelengths and moving shadows. The
stables are lit via indirect illumination
and from glare- free linear sources
which ensure good vertical illumination
on the faces of the horses.
“The covered arena, though simpler
in some aspects proved a different
challenge, it is a full-fledged Olympic
grade show-jumping and dressage
venue, complete with broadcast quality
lighting,” says DJ.
KEEPING THE SPARK
“Power supply is one of the biggest
challenges with the Willinga project,”
says Neil Shepherd of Shepherd
Electrical. “Bawley Point is a small
coastal town that is simply not used to
having such a huge point of load from
one customer. As a result, solar PV and
generators have to be used to provide
what we need.”
Power generation is currently
supplied by two utility pad-mount
sub-stations distributed strategically
around the property, supported with
stand-by diesel generators should
power go down. Solar panels provide
approximately 100kW. The sawtooth
roof on the Covered Arena provides
75kW while another 25kW is from the
workshop roof. The diesel generators
are designed to provide 72 hours power
capacity at full load across the whole
facility.
The primary source of power is
solar, but should the day be cloudy or
the battery storage is low, the grid
is utilised to re-charge the batteries
using the off-peak tariff. The majority
of the power drain is through lighting –
particularly for night events when the
arenas, pedestrian areas and roadways
need illuminatiopn.
Other power users onsite are the
heated horse hydrotherapy pool
which requires an electric heat pump;
water distribution pumps using VSDs
for pressure on demand, plus three
Stiebel Eltron instantaneous hot water
systems. In addition, the hydronic
heating system pipe work incorporated
into the reception building slab for
future use, has now been connected.
Cold winter days are not uncommon in
the region says Neil.
Neil and his team are also in the
process of installing a BMS Scada
monitoring system that is able to
identify any alarm or alerts from pumps,
solar PV, batteries – wherever there
is a requirement for notification to
tradesmen.

holiday home, a storage water tank of
