Energy Modeling is a software simulation of a building’s energy use that can be utilized to optimize and reduce energy usage while maintaining optimum building performance. The Energy Modeling software program utilizes numerous building characteristics (envelope construction materials, lighting systems, HVAC distribution, water heating, and renewable generation systems) to “construct” the building simulation, also factoring in the building’s schedules for occupancy, plug-loads, and control system settings (thermostats, airflow, etc.). When an Energy Model has been created using design documentation and drawings (or compared to site conditions and utility bill consumption for existing buildings) an energy specialist can then fine-tune and optimize energy related parameters and recommend detail energy conservation measures that have the potential to provide thousands of dollars in savings.
Energy Modeling is a great tool for building owners to make key business decisions that may end up saving them a lot of money. Whether it is a new construction or an existing building, Modeling offers great insight as a decision making tool.
Energy modeling is a great tool to use when you have to choose between multiple system design options.
Whether it is HVAC system, lightning or the plumbing system, with the right tools and knowledge, reports can be generated on how the system will perform under various design options. All the choices can be simulated within a very short time and help the decision making a lot easier for building owners.
Existing buildings can also be modeled and simulated. Generally, existing buildings are simulated to find out if a system is causing excessive leakage of energy. It can then be used to improve the systems and even calculate the return on investment if you replace the older system with an existing one. Energy Modeling is also used for setting Energy benchmarks in retrofitting projects.
