Basically, there are many sources of heat load that happen during the ceremony in hall the when
it using. Large number of occupants, each of occupants will comes with their own gadget,
lighting, and computers for PA system contributes to heat load causes which can make
uncomfortable condition throughout the ceremony, especially for the important guests. Below is
the description for each of the heat load causes from the hall when it is used for any ceremony
during sunny day;
a) Heat from human beings
Occupants are major source of heat in building interiors. Considering that a human consumes
hundreds of calories each day in the form of food, and part of this energy is released as heat
during metabolic processes. The heat released by humans is even higher during intense physical
activity, through perspiration. The heating effect of humans also increases depending on
occupant density. As a result, the human contribution to the total heat load can be especially high
in the hall.
b) Heat from electrical and electronic appliances
Indoor space in the hall are filled with electrical and electronic appliances such as lighting
fixtures, smartphones for each occupants, laptop and LCD monitor. These appliances consume
electricity and release some heat in air-conditioned spaces.
c) Solar heat gain
Three different ways in which heat from the sun can reach interior space of the hall which are
conduction and convection. Conduction occurs across walls and roofs of the hall since they are
exposed to a temperature difference between the hall interiors and the warmer outdoor
environment. Convection refers to heat transfer from surfaces hot outdoor air or indoor air
movement to surfaces at different temperatures.
