Energy Modeling
From Swikipedia
Introduction
Energy modeling is a computer model that analyzes the building’s energy-related features in order to project energy consumption of a given design. It serves as an important tool for understanding the requirement of efficient design and development during the building design process. It includes all the possible parameters like weather, occupancies schedule, and building envelop, Systems and more, except natural disaster which has an effect on energy consumption.
Brief Description
Energy modeling is the most comprehensive integration of individual routine for HVAC, lighting system, chiller and building envelop and to develop a good energy model, the data entry should be strategic. Once the energy model for a building is ready with the desired input, it gives off results in the form of load breakup annual energy consumption and even the breakdown of energy consumption, which can be system wise breakup or equipment energy use breakup or zone wise breakup.
Benefits of Energy modeling:
• Energy modeling can help optimize the building design and allow the design team to prioritize investment in the strategies that will have the greatest effect on the building’s energy use.
• It can be a powerful tool in an integrated design process as it takes into account all the possible parameters.
• Energy modeling can provide valuable input during the conceptual design of the project, as it can be used to test the effects of site location, building massing, and building orientation.
• Energy modeling allows the design team to focus on the major drivers of energy use during schematic design.
• It also permits parametric studies to be done during design development, which allows a better understanding of the energy use of each building component. A series of simulations are done in which one component of energy use is set to zero at a time. When the results are viewed, a clearer picture of how the building uses energy emerges.
