Simulating the energy needs and usage in a building before it is constructed is possible thanks to technology. Energy modeling software is used to simulate whole building energy performance to ensure the right decisions are made during the design and construction phases of projects. Software tools make it possible to consider all the interior and exterior elements that influence energy consumption.
Instead of just considering the type of HVAC system, building designers and contractors can input additional elements like the building envelope and the local climate. Ideally, energy simulation strategies are also used to also monitor and assess energy performance after building occupancy to achieve optimal operations and maintenance in terms of energy consumption. This course explores the topic of energy modeling and the availability of free energy modeling software like eQuest for green building design.
