Convective heat emitted from LED lighting affects indoor
thermal
conditions in buildings and increases the indoor air
temperature
and cooling load in the summer. A new thermal management
model for integration of LED lighting with an HVAC system
was
proposed to prevent this heating effect in buildings. To explore
the
applicability of this model to buildings, field measurements and
an
indoor thermal load analysis were conducted for two seasonal
operating
modes. From the measured data, the lighting heat input
fractions
for simulation modeling were determined, and the indoor
thermal
loads for cooling and heating were compared with a base
case
using the building simulation software EnergyPlus, based on
the
heat balance method. Finally, the annual site energy uses in
buildings
subjected to various climatic conditions, from hot and
humid
to cold and dry, were compared to analyze the building
energy
reduction effectiveness of the model. The following conclusions
were
drawn
from the results of this research.
