Building Energy Modeling

Posted by: Admin | Posted on: November 12th, 2012

Building energy modeling is a procedure in which an in-depth analysis of the building systems is being undertaken and various strategies are being developed in order to optimize the energy performance of the structural buildings. By the help of the energy modeling, the engineering team analyse the fact as how different systems interact within a building project and based on the results, they develop various integrated designs.

Building energy modeling is the basic tool required in order to give rise to high performance buildings. The professionals who perform the energy modeling procedures are known as energy modellers and their main job role is to oversee the design, construction and building phases of the different structural projects. The buildings which are constructed using the energy modeling procedures get the green building certification.

What Is The Need Of Building Energy Modeling?

  • Conservation of energy: According to a survey report, the buildings in United States consume about 39 percent of the energy and 68 percent of electricity. The building energy modeling approach makes use of innovative technologies in order to design and construct energy efficient buildings. The modellers carefully analyse the working of the building components in relation with the internal and external environment.
  • For sustainable infrastructure: Sustainable infrastructure can be possible by improved energy efficiency and the security technologies. It requires effective monitoring of the heating, cooling and the ventilation systems. It requires effective installations of the fire protection systems and the alarm systems. The building energy modeling concept plays a vital role in performing the above functions.

The Whole Process Of Building Energy Modeling

Here are the general detailed steps of the whole building energy modeling procedure:

  1. Preliminary energy audit: In this phase, all the energy related data is being collected and based upon the results, the component specific energy saving strategies are being drafted. The various design drawings and the equipment specifications are being required as input to conduct the energy audit.
  2. Improvements in efficiency: After getting the detailed reports of the energy audits, proven energy efficient systems are being installed in the structural projects.
  3. Monitoring of energy: In this phase, different energy monitoring systems are being used to track and control the energy usage of the individual components of the system. This helps in the identification of any type of inefficiencies present in the system.
  4. Development of renewable energy: This is an important part of the whole building energy modeling process. In this phase, various sources of the renewable energy are being inspected and the right source for the particular project is being selected and developed, in order to further reduce the energy costs.

Benefits Of Building Energy Modeling

The building energy modeling is crucial in the various phases of the project design such as the pre-design phase, schematic design phase, design development phase and the constructional documentation phase. In the pre-design phase, modeling helps in evaluating the climatic and the site conditions. In the schematic phase, modeling helps in determining the various building concepts such as zoning strategies, thermal loads, form and orientations and the day lighting strategies. In the design development phases, energy modeling helps in optimizing the various system controls and identifying the various opportunities for the energy recovery. In the last constructional documentation phase, modeling helps in determining the set points for the calibration of the equipment’s.
