Calculate HVAC loads with BIM

摘要

VAC cooling and heating load analysis for buildings currently is performed by using widely available software tools. For the past 25 years, this method has become the status quo for HVAC design engineers, and it has proven to be an effective way to accurately calculate building cooling and heating losses.rnHowever, this method has some disadvantages, including tediousness of inputting data for large buildings and difficulty in reusing the inputted building data for other types of analysis such as lighting and energy calculations.
