What Exactly is Energy Modeling and Building Simulation_
                     What 
exactly is 
Energy 
Modeling 
and 
Building 
Simulation?
Introduction
Energy simulation modelling is a virtual or digitalized 
simulation of a building or complex that focuses on energy 
consumption, utility bills, and the life cycle costs of various 
energy-related items such as air conditioning, lighting, and 
hot water. It is also used to calculate the return on investment 
of green energy solutions such as solar panels and 
photovoltaics, wind turbines, and high-efficiency appliances. 
Understanding building simulation is essential for 
understanding energy modelling:
Who is benefited by 
energy modelling?
● Engineers (no more massive spreadsheets!
● Manufacturers (Quantitatively prove that your product saves money in 
X amount of time.)
● Owners of buildings (Get the most bang for your buck up front)
● Tenants of a building (lower monthly bills!)
● The Natural World (one can determine the options to use the least 
energy and have the least emissions)
● As well as MANY MORE BENEFITS!
How do I create an energy-
model or a building 
simulation?
The right software is required to simulate a building on 
a computer.
Although either software package can be learned 
quickly, becoming a master takes years (just like 
anything else worthwhile).
What do I need before I begin 
Energy Modeling?
● Geometry and building location
● Materials for construction (walls, windows, u-values, shading 
coefficients)
● The building's overall operation
● Every interior load value (Lighting, plug loads, occupant numbers and 
activity level).
● System types (is it constant volume or variable air volume? DX coils or 
ice cold water?) - If you don't know what type of system you have, you 
can use a model to determine what is best!
● You must be astute...
Which software is the most 
effective?
This is not our place to say! We don't want to receive a lot of hate mail. Each 
package has advantages and disadvantages. Some packages have excellent 
functionality but a poor user interface, while others have excellent user 
interfaces but limited functionality. It is entirely dependent on what you are 
doing.
eQUEST is probably the quickest and also cost-free option. Keep in mind that 
it is almost entirely focused on energy, and that load design in eQUEST 
should be left to the experts.
If you need to do Load Design + Energy, the TRACE 700 is an excellent 
choice. Tell your boss to swallow his pride and buy it for you. It includes free 
support.
Alternatively, if you are only interested in Load Design, TRACE 700 Load 
Design is an option (it costs much less and you still get unlimited support).
