Optimation of Electrical Energy Generation for Low Rise Office Building with Folding- BIPV Concept

Abstract

BIPV is an architectural concept that
related to energy contribution. The system has
functions of producing electricity as well as building
form giver. The effectivity of BIPV depends on solar
radiation received. Meanwhile, the solar radiation
received depends on numbers of solar receiving area
and environmental shading. Environmental shading
will decrease the effectivity of BIPV. But, integrated
configuration of folding-BIPV is expected to create
more numbers of solar receiving area. The integrated
configuration of folding-BIPV will create optimum
BIPV, both in electrical generation and building form
giver. Experiment to low rise office building in
tropical climate is done by giving folding treatment.
The experiment also considers about environmental
shading. Evaluation is done by analyzing and
optimizing the numbers and uniformity of solar
radiation received. Simulation with ARCHIPAK 5.1 is
used as experimental research tool. The simulation is
used to calculate annual radiation received (kWh/m²)
from folding-BIPV configuration. Manual calculation
is used to calculate total annual radiation received
(kWh) and uniformity percentage. Gradient diagram
is used to do the optimation. Result of this research is
an optimation of electrical energy generation in low
rise office building which use folding-BIPV concept
