| Summary: | Incident solar radiation that falls in building surface has
effects in energy load. Cooling load is one of the highest
energy consumption in buildings, especially in tropical
country. Many researches are done to cope with this
problem. Many solutions are offered, from as early as
finding the optimum form, changing building
orientation, exploring the use of sun shading, to
implementing technology in a building. This paper aims
to measure the performance of L-shaped mini louvers in
a glass window to reduce solar radiation as one of
solutions that may be simply used in buildings. The
research uses simulation methods to compare the results
of blocked solar radiation in glass window with eight
different orientations throughout the year. Simulations
are done for two locations, in Singapore and Sydney.
These locations are taken to get insight of the
effectiveness of mini louvers in tropical and sub-tropical
area. Singapore has relatively hot temperature all year
round; meanwhile Sidney recently has temperature that
nearly breaks its record 80 years ago. The simulation
will utilize Rhinoceros with Grasshopper plug-ins plus
Ladybug. The weather data are obtained from United
States Departments of Energy website. Simulation result
shows that mini louvers can reduce solar radiation and
work best for north direction in Singapore. In Sydney,
type 1 and 2 windows work best for north direction
whereas type 3 works best for southwest direction.
