Energy Modeling is a simulation software that analyzes a building’s energy performance. It’s the most efficient tool to determine Capital Expenditure (CapEx) for optimizing energy usage and achieving low carbon emissions. The software program utilizes numerous building characteristics (e.g., envelope construction materials, lighting systems, HVAC distribution, water heating, and renewable generation systems) to “construct” a building virtually. It also factors in the building’s schedule for occupancy, plug-loads, and control system settings (thermostats, airflow, etc.). When an Energy Model is 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 can save thousands of dollars.
Using Energy Modeling to make Key Decisions
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.
New Construction
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
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.
