|Title:||NIST Technical Note 1735 LoopDA 3.0- Natural Ventilation Design and Analysis Software User Guide|
|Published:||February 22, 2012|
|Abstract:||LoopDA 3.0 is an update to version 1.0 of the natural ventlation design tool developed by the Natural Institute of Standards and Technology. This software tool can be utilized to determine the size of natural ventilation openings necessary to provide a airflow rates that satisfy design requirements based on minimum ventilation and cooling load requirements. The method employed is based largely upon the Loop Equation Design Method that provides for sizing of openings to utilize driving wind and stack pressures to achieve design airflow rates. This version implements a simple thermal design calculation to assist in determining design tempertures and airflow rates and provides a more streamlined interface to more efficiently implement the design process as compared to the previous version. A simple design example is also provided.|
