Implication of Design and Operation on Cooling Load and Energy Cost for Academic Building At UTP

Cooling load of a building is very sensitive to the design and the operation of the
building itself. Every building from academic complex is unique, in a sense that
different designs and operations have different cooling loads. And it is very desirable
to determine the cooling load, so the operation of air conditioning system reflects on
the building’s specific energy requirement. This will provide a good balance between
occupants comfort and the related cost of running it. The objective is to determine
the repercussion of design and operation on cooling load and energy cost of Building
17. This project captures air conditioning operation data and translates it to a more
understandable output, so that operators understand what is happening with the
operation of air conditioning system. The samples data show that the peak operation
time is between 3 to 7 pm , with the maximum indoor temperature of 27C and
average flowrate of chilled air at 388 l s for that particular time period. It is clear
that the operation of the system is heavily influenced by outdoor weather and the
electrical appliances inside the building, with several outliers caused by improper
actions by users, faulty equipments and system trips.
