Study of Energy Simulation and Its Scope

Posted by: Bhushan Avastthi | Posted on: April 30th, 2013

The study of energy simulation assists you in taking informed decision in the design as well as construction of the buildings from the point of view of energy consumption. We can utilize this tool to help us settle on the right or optimum equipment and material specifications in a systematic and scientific manner.

The process of energy modeling and lighting stimulation devises simulation model for the optimum use of energy efficiency of the proposed projects such as:

  • Building Envelope (Windows, Wall, Roof, etc.)
  • Day lighting simulation for the optimum use of natural lighting and lighting controls.
  • HVAC systems and its related components.

Professionals working in this field conduct whole building simulation work and also help in assisting design teams to perk up overall energy efficiency as well as reducing operating costs in new multi-residential, commercial and institutional buildings.

Scope of Work:

  • Building performance analysis is a tremendously powerful way to evaluate, analyze and quantify various design concepts and low carbon technologies
  • Defining modeling assumptions
  • Detailed building simulation and energy modeling
  • Formulating proposed as well as base case building simulation model
  • Energy reductions can be achieved significantly
  • Occupant comfort can be ensured
  • Multi-disciplinary decision-making is ascertained

A building energy simulation program is by no means less or more than a calculation of a building’s energy use hour-by-hour, by means of complex thermodynamic equations, which takes into account the building’s internal conditions, the invariable changes in the weather and the building and space conditioning system’s vibrant response to such changing conditions. Energy simulations, specifically when used in concurrence with measured data, are the utmost technically defensible and reliable method for ascertaining energy savings in buildings.

Such programs are very superior in keeping track of the building physics. These programs are however not good at predicting occupant behavior. The leading grounds of error between the usage of simulated and measured energy are the differences between of the building’s assumed and actual operating schedules.

Energy Simulation have been utilized to demonstrate compliance to building energy standards for over twenty years, not just in the U.S., but also increasingly in several other countries such as India and China. These tools and techniques are also utilized for assessing DSM projects to go beyond the building energy standard, for calculating energy credits for green building certification (for instance, LEED), and for determining the energy savings from building efficiency projects. Even when measured data are plentiful, the tools of energy simulations are still required to normalize the data for changes in human behavior, differences in weather, or other exogenous effects.
