The objective of our project is to buildup a
baseline model of two campus buildings and
validate results with actual data. With this
approach future estimation of building
electricity consumption, cooling load, heating
load can be done which might help the
energy manger to take some crucial decision.
Objective
AET Building
 Total floor area: 145440 SFT
 4 Floors, 24 Zones
North-East view South-West view
BSB Building
 Total floor area: 95,440 SFT
 3 Floors, 22 Zones
 Building geometry in SketchUp
 Zones are selected based on each floor
internal room distribution
Building Geometry
 For BSB three AHUs, 90VAV boxes and
single duct system
Modeling Approach
 Lighting and Standard 90.1 – ASHRAE
 Occupant load requirements,
International Code Council online library
2009

 The model can be made more dynamic
by introducing more complex control
schedule to catch up the real time
behavior.
 Also any new idea to improve the energy
efficiency of the building can be applied
to it and compare the improved design
with the previous design in terms of
energy consumption.
